2023 Hyundai Sonata

On a highway cruising at 70mph with the acc (adaptive cruise control ) on and following distance set at max a car from another lane turned into my lane and then continued to an off ramp. my car initially braked and then downshifted from 8th to maybe 4th and accelerated hard - scaring me and my passengers. i did add to the actions of the car by pressing the following distance button on the steering wheel a few times. i had owned a 2016 sonata with acc and drove over 100k miles with acc operating. that is why i pressed the following distance button - to lessen the actions of the car when the car entered my lane. the 2016 also had a acc setting of fast, normal, & slow (i used normal). the 2023 has no acc setting. i did complain to my dealer and he said this was normal and nothing happened. i feel this is dangerous so reported it to hyundai customer service. they told me to go to my dealer.

P074d73 is code showing up coming up and going off after sometime. this is code something related to the transmission. worried if it could cause the transmission to fail which may result in loss of power during the drive which could potentially cause fatal accidents. it occured multiple times. attached the screenshots

While on the highway, my car suddenly started shaking violently and losing power. i lost steering and was unable to accelerate. i pulled over to the side of the road and the vehicle would not start again. i took it in and a fuel injector was stuck open and it had flooded my engine. this was the second time with this vehicle that this happened.

Moonroof shattered yes could have lost control due to fright/heart attack no insurance said it happens to hyundai often no warning at all

I was driving on the freeway, at the speed limit, cruising along. then all of a sudden, my vehicle starts to decelerate from 65 mph and i push the gas, thinking i must have let up too much on the pedal. however, that only causes the rpm to drastically rise with no change in my speed. i thankfully managed to maneuver from the far left lane to the freeway shoulder on the far right. the whole time, my speed was around 40 mph and dropping drastically. trying to safely navigate a slowing vehicle on a 65+ texas freeway is an adrenaline-rush that i wouldn’t wish on anybody. i was severely panicking. i was almost hit by several vehicles in my maneuvering. i could have died last night. once on the shoulder, i tried to start my car. i thought it may be a battery issue, but it turned on. it didn't start, though. the lights came on, as did all of the typical system/dash lights that usually indicate when a car’s engine hasn’t “turned over.” i used bluelink to call for roadside assistance (since i’m only a little over 2 months into ownership) and waited. i was escorted off of the freeway to safety — thanks to a 3-car police escort and free city tow trucks — and eventually picked up by hyundai-serviced aaa. the latter then towed my vehicle to the dealership where i bought my sonata. my car is currently being checked/inspected by my dealer (north freeway hyundai) and i only have gotten the following notice from bluelink: "a possible condition with your engine control system has been detected with your 2023 sonata on 02/22/2023 at 07:23 am cst. a full system check is recommended to be done soon." i checked and there are no open recalls (currently). even more concerning, my car recently underwent complimentary maintenance, including an oil change, through my dealer (on february 13, 2023 - i have the receipt), was good on gas, and had no warning lights displaying. until it stopped running — the time i tried to start it on the side of the road, the dash showed an “engine” light.

I want to say through this message exactly a month ago that i bought my hyundai sonata sel 2023 and today driving the car it completely lost power when accelerating so i had to stop immediately i put my turn signals after that i turned off the car! i opened the hood and i didn't see any smoke coming out until that part, everything was fine. then when i tried to start the car, it made a strange noise and a strong smell of gasoline began to come out! try several times and the same result that the car does not start the engine makes strange noise and the smell of gasoline is very strong that i had to get out of the car and leave it off, at the time i write this message i am still waiting for assistance!

This is the second incident with the same issue. both times the car starts to shutter and when you give it gas it doesn't do anything and then it just dies. no steering no brakes nothing. you may or may not be able to restart the car to move it if it breaks down when it's in traffic, luckily we were able to get it fired up long enough to move it off the road.

Water continues to gush out of the driver side passenger door when opened after raining. i also found out on friday, july 30, 2023, that water has been leaking into the trunk of my brand-new car since purchasing it on may 10, 2023. it's a hybrid. [xxx], pearson hyundai's new car sales manager (who i bought my car from), and i are extremely concerned about water leaking into the trunk of an electric vehicle which puts me, my family and anyone else who rides in the car at potential risk. currently my car is at pearson hyundai again to fix this issue for the fourth time. attached are the three previous service invoices that i've received. if needed, i can provide three videos that i recorded of the same issue on may 30th, june 17th and july 1st. please know that i have also shared the videos with [xxx], pearson hyundai's service manager and [xxx], pearson's service advisor. on july 3, 2023, i filed a report with hyundai customer service. the case number is [xxx]. the last text i received from [xxx], pearson's service manager, yesterday (7/5/23) follows: "i’m sorry i don’t have any answers yet, we’re trying to figure this out, i’m even reaching out to somebody i know when the collision industry that understands body framing-- sent from gmail mobile" information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Dtc subsystem ems failed engine over heated. car diagnostic failed displaying p00b700. hyundai issued tsb covering issue dealer failed to notify since nhtsa did not require action. car has been in garage waiting for appointment. this could have left me stranded.

When i approach an intersection to stop my car auto shut off engages. when trying to hit the gas to release my car from auto shut off the emergency auto shut off engages and i must put my car in park. turn the ignition to off and then crank my car back all the way on. release the park and drive. this happens intermittently for several weeks and i’ve almost been rear ended several times. i have taken the car to a hyundai dealership for the issue and they tell me nothing is wrong.

The power-operated driver seat has moved on its own, without warning, while the vehicle is in gear, potentially moving the driver away from being able to reach the brake pedal or otherwise control the vehicle. the vehicle uses seat position memory pre-sets and/or driver profiles, such that even if a new driver sets the seat position manually or by using a pre-defined memory setting, will move the seat to the position it was last driven in. the driver can stop the seat from moving further by either activating the seat position controls or by selecting a seat position memory setting.

Purchased a new hyundai 2023 sonata from mcgovern hyundai rt 2 may 22, 2023. after two weeks of driving the vehicle, i noticed it hesitates when i push down on the gas pedal. i had planned to have the dealership take a look but have a very busy schedule, the issue continued each time i drove the car to the point it was hesitating, basically pausing as i cross intersections. on the 26th of july i was driving on the highway, as i started to experience issues when stepping on the gas. entering a tunnel in boston, i pushed down on the gas pedal and noticed the car was decelerating, i was losing speed, in a panic in the center lane of the tunnel, i was able to get the car over to the far right. the car was shaking aggressively then finally just gave out and i called 911. they towed the vehicle to the police headquarters, i called hyundai for assistance. had some hiccups but two days later they were able to service the vehicle, supposedly found a faulty fuel injector. they changed out the 1 faulty injector test drive and said the problem was fixed. i picked up my car on july 28th 2023. there is something still wrong with the car, it still has some hesitation and now misfires. have not heard from hyundai, i was assigned a case manager and told someone would follow up, no one has reached out. so lucky my children were not in the car and that i'm safe. i could have been killed, others could have been hurt/killed. this should not happen to brand new cars.

My concern is a potential unintended acceleration forward as. i was. parking vechicle. sudden burst of speed, went thru shrubbery and off a 2 foot wall. felt as if we were taking off a runway in a plane. car went nose up over the wall and then dropped into a neighbor yard digging a divot, ripping rear left fender and bumper with some undercarriage problems. my spouse and i were seatbelted and not injured. i can not recall any safety warning until car stopped and then do recall a message being on dash but cannot presently recall what it said. vehicle currently being worked on at collision center where insurence appraisor gave go ahead with estimate to repair damages

The brake rotors are faulty and become warped at 9k mile i now have 27k and are extremely warped causing braking issues at higher speeds. i have been waiting over two months for new rotors from the dealer with no word as to when they will arrive. if the vehicle is left un-driven for a couple days the rotors will become rusted. even the brand new vehicles in the hyundia showroom are covered in rust. the suspension of the rear shock are extremely weak and bottoms out on the smallest rut. cornering i’m the vehicle is subject to enormous amounts of whee hop which could result in an accident.

Transmission goes into limp mode please note this is an n line and shift points are low taking off from a light vehicle goes into limp mode in first 150' cars to the rear almost ran into the back of the vehicle. car is 2 days old and i have an appointment tomorrow to have it looked at. this sounds like similar problem that caused a recall last year on the 2022. this is a dual clutch auto.

My 2023 hyundai sonata limited has an issue where water enters the rear left door and gets trapped between the lower door seals. water pours out when the door is opened. a google review of "sonata rear door leak" shows this is a wide spread issue with this door and car model. if this were to occur in a northern climate the door would have ice collect between the door and door sill and prevent the door from opening in an emergency. google shows numerous people have tried to get this addressed . most with no success from hyundai. i had taken my car to coconut creek hyundai in coconut creek florida in aug 2023 and was told "this condition is common to the model". no fix attempted. i escalated to hyundai usa, and they literally stated they cannot superceed the dealer and to take the car elsewhere. they ignore the door issue and also stated on recorded call ( their recording) that this condition is common to the model. i fear the first accident that the door cannot be opened due to internal ice collection. please just google "sonata water in doors" to see how common this is!

Forward collision warning appeared, vehicle lost power and would not accelerate. vehicle kept loosing power. multiple codes appeared. i am an ase certified mechanic, so i went to my own business to get my scanner and there was a list of codes. vehicle is currently at dealership and they are tracking down issues. currently blaming an ecm but unsure. this is the second vehicle i have had this exact issue with. i have video that it won't allow me to upload of all the codes. i have a video of a previous issue, with a different vehicle. it's a 2023 hyundai santa fe

The contact owns a 2023 hyundai sonata. the contact stated that on two separate occasions while driving at various speeds, the vehicle started to shake, and the vehicle lost motive power. the vehicle was pulled over to the side of the roadway and turned off. the vehicle failed to restart on both occasions. the vehicle was towed to a dealer where it was diagnosed that the fuel injector needed to be replaced. the vehicle was repaired. the manufacturer was notified of the failure. the failure mileage was approximately 11,000.

Vehicle’s front collision sensor popped up on dash, vehicle lost all power. almost was hit by a group a semi trucks hauling a wide load that wouldn’t have been able to stop in time. this is the 3rd time it has happened in a week and a half.

Took a trip to the grocery store, and started up my car when i got back. the engine turned over but after a few seconds, it stalled. tried this again, but lightly pressed the accelerator. this raised the rpm, but it dropped quickly and stalled the engine again. made a couple more attempts after and eventually, the engine light came on. shortly before this incident, i had about 10-15% of gas left in my tank. after this happened, bluelink reported that i had 1% left. got the vehicle towed to the dealership, where they confirmed the condition and found that the fuel injector for cylinder 3 needed to be replaced. i consider myself lucky that this happened while my vehicle was parked. this would've been a huge safety concern if it happened out on the road.

I was traveling on the freeway when i began experiencing erratic acceleration, around which time the check engine light came on. i took the next exit, and continued to experience the same symptoms, as well as rough idling, and a bit of smoke. the car was towed to the nearest hyundai dealership where the fuel injector was replaced under warranty.

Sunroof burst while driving on freeway at a low speed due to heavy traffic. there were no overpasses or bridges above the vehicle when explosion was heard. no point of impact on sunroof from possible rocks and glass is shattered but in one piece and it appears to have burst outwards as it’s bowing upwards. sunroof had rarely ever been used prior to this and vehicle is only 1 year old. only some tiny pieces of glass came off initially, but headliner collected them instead of landing on driver/passenger while driving.

Driving going 30 mph, vehicle stopped accelerating. error code was engine control system failure. codes p2178, p0301 and p0087f0 were shown at dealership. car was taken to dealership for repairs where the fuel injector on cylinder #1. 16 days after receiving car back, we went to start the car and it wouldn't start. after several attempts, gasoline began spewing from the car leaking an entire tank of gas on our garage floor and driveway. very dangerous! being towed to dealership again today.

Instrument cluster lighting is too bright even on lowest setting. combined with poor side visibility from headlamps it is easy to hit object or pedestrians when turning on unlit areas. have run over a curb three times and damaged two wheels because they can't be seen from the overly bright instrument lighting at night.

Had been traveling for approximately 2.5 hours in a winter storm, pushed on brake to slow down and park and the car started to chug. turned car off and then back on again. car would not start and had to be towed to nearest hyundai dealership. there were no warning signs at all, car just suddenly quit. we were later informed that it was the fuel injectors. we were very fortunate that this did not occur in a place with no cell service on a very frigid, stormy night.

The car did not shift from drive to park after coming to a stop and pressing the park button. this caused the car to roll forward slowly and run into our garage door. this is not the first time the car hasn't shifted.

This is the 3rd time it happened to me. i was driving on the highway at speed 60-70 and a flash came across my dash that said emergency brake warning and my car started slowing down. i panicked and pulled over the road. the warning came on so fast and not even a min it stood on. it went off within 5 seconds. this is a safety hazard and can cause death when this happens. please issue a recall for this to be fixed because this is dangerous to me and other drivers. i want my money back because this is the manufacturer defect or issue. they need to correct this before fatalities happen.

The hyundai sonata was brought to a stop in a parking lot. when the driver went to put it in park, the vehicle accelerated across the parking lot and smashed into a solid wall. the driver broke her right ankle from standing on the brake pedal. the brakes were ineffective at stopping the vehicle. the collision avoidance system failed to activate or warn of the impending collision. the driver and passenger were severely injured and the car is considered a total loss. there were numerous other injuries sustained. no one outside of the vehicle was injured.

I have had three occasions where the dashboard lights would flash and the car would lose all power. the first occasion occurred on december 29th at around 12:20 pm at a crowded intersection. the dashboard lights lit up and all of a sudden the car had no power at all. i managed to get it through the intersection and pull it off to the side of the road. to start it up i have to turn off the car by putting it in park and start it up again. this is stressful and terrifying to think about if this had happened on the freeway. additionally, i took the car to get serviced and was charged a $1,800 bill to fix it in january. this repair took two weeks to complete. the car has since turned off two additional times on february 15th going down a hill at 40 mph and march 26th on a mountain road going 60 mph. i am very concerned this will happen on the highway and i will get into a serious accident or worse. to make matters more difficult, i have taken the car back to the hyundai dealer again to have it looked at in april and will most likely be without the car for at least another week. i bought the car brand new and the check engine light has gone off four times since then.

See attached document for complaint

The car would not accelerate, nor switch gear while i'm driving middle of the highway. the car engine started to shake after my car wouldn't switch gear. the car engine would not start after turning the car off and caused a engine misfire. the transmission gear has a hard time switching gear from 0-40mph. this same incident occurred twice since purchasing the car in late november 2022.

My car randomly engaged emergency brakes while driving 70+ mph on the highway with no cars nearby. it almost came to a complete stop but i was able to accelerate again. it was not acting as a safety features because there was not a car close to my front. i am concerned if it happens again i could get in a crash and rear ended. the dealership does not seem concerned

On two separate occasions, one at @9500 miles and the next at @19,000 miles the car engine started shaking and lost all power while driving. unable to steer car. both times towed to dealer and they say it needs new spark plugs and need to clean cylinders. they do not know root cause of problem and have not done any testing of the engine, no leak/compression testing. dealer refuses to cover cost of repairs saying out of warranty but cannot give any assurances this won’t happen again. i’ve requested they contact hyundai engineers to find out what’s causing this and, to date, they’ve done nothing. vehicle is unsafe to drive and is still at dealership with no reason to underlying issue.

2023 hyundai sonata limited, 1.6 t. battery discharged within 10 days while parked. this problem is well known to dealership. the dealership has to jump start cars and start them frequently on the dealership lot. it is impossible to park this model car at an airport or parking lot for more than a couple of days and maintain a battery charge. no warning or alerts. the problem is that the reserve amp hours of the standard stock battery is not adequate to supply the electronic drain of computers while parked.

I was driving on the interstate at interstate speeds and the car started to lose power. i was able to steer the car to a safe location and call roadside assistance. it appears that the engine control system had a failure in one of the control modules. the problem was reproduced at the time that i dropped the car off with the service center. the history of the issues for the vehicle are available. my safety was put at risk because the car lost power at high speed and i was only able to limp to a safe location. no warning lights happened until the issue was already taking place. after being notified by my hyundai app, i was able to discover that the vehicle had a history of having this code (i have only owned the car for 32 days)

At 82,000 miles car started to consume coolant. had ehrs tbs performed coolant no longer leaking. thi is the 2nd car that had this coolant issue.

Hello, i have hyundai sonata 2023. the fuel tank of this car is expanded on [xxx]. i have never heard about this issue to any cars. i took my car to dealership they said they don’t know why this happened and they said they cannot fix it, my car at the dealership more than a month. i have created a case with hyundai corporate office in ca, it’s been a month since this case was created and i could reach out to my case manager only twice for this period of time. they are keep saying they are working on it, but no results they don’t even look at my car. today i barely could reach my case manager and she told me that this is not under warranty and i will need to fix it out of my pocket. when i bring the car to the dealership they told me this not under warranty since warranty was up to 60k miles, i have 90k i asked them to fix it and i will pay but they said they don’t know how to fix it. today i have researched and found that this issue is really common among kia k5 and hyundai sonata’s 2021 2024, i will provide a link here: [xxx] please check this link and you can see that most of the cars fuel tanks are expanded and back seats popped up. i have same exact problem. kia asked drivers to inspect the cars with this issue and they said they will fix it for free since this is fuel tank defect. but what should i do with my hyundai sonata. i have same exact issue as you see at the link i have provided. i had powertrain dtc po451 since march of this year dealership said just check if gas cap is on properly, but this caused this issue i see hyundai will not help me it will almost 2 month i don’t have my car and i am still paying for it, please let me know what i can do thank you! information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

On 3 separate occasions the vehicle decelerated, lights flickered and stated to produce a burning smell through the engine. each time the car would not allow me to accelerate and eventually stalled out. the car would no immediately start. after a few minutes it would start but not accelerate. after about 30 minutes it would start and would drive about 5-15 mph, enough to get me to my location. on the first occasion i was coming home late in the evening after working a 12 hour shift and had to have a family member get me after being stranded by the side of the road. the second time i was taking my 4 to son to his planned surgery in a bigger city and it broke down on the way. it was not safe driving in the city barely being able to excel but we did it for my son. the third time i was in a larger time in traffic and missed an appointment as i tried to stear my decelerating vehicle out of multiple lanes of traffic to a safe location. i could not use the air conditioner while i attempted to let it rest in 100°+ heat. each time the lights would flicker and dim. there would be a smoke from the exhaust. after the first 2 occurrences we took it to the dealership but they were not able to replicate the problem or identify a causative code. during the last occurrence we were able to get it to the dealership very slowly and they deemed it to be the fuel injector malfunctioning. this was fixed after about a week or so of being in the shop . about a week or two after the fuel injector was fixed the check engine light came on. we took it back into the service department and they "reset" the system thinking it was an error. the light came back on in less than 24 hours. the vehicle has been running a little harder, not as fast or responsive as normal. a service/evaluation date was scheduled and the code was checked indicating it was likely the catalytic converter. we scheduled another service appointment once the part was in which is 2 weeks from the evaluation appointment.

I have been having transmission issues the whole time i've had the car. there is a delay upon take off, and it bogs down instead of downshifting. i was driving my son to school and made a left turn. it started to go but then delayed for 10 seconds before suddenly taking off. if the on coming traffic had been closer, they would've hit us. the dealer has reproduced the problem but can't get enough information for the tech line to approve a new transmission even though the dealership has repeatedly said that is what it needs. i've never had a warning light on it. it's been in the shop for it this time since 7/26/24.

My name is [xxx] , and i am the frustrated owner of a 2023 hyundai sonata sel. for context, i am a [xxx] woman who had never experienced the frightening event of a “brand new” car breaking down—until now. i am still in shock and trembling from the experience i had with my “new” 2023 hyundai sonata on the morning of [xxx]. at 9:30 a.m., i was driving on [xxx] . i was driving the speed limit (55 mph) and cruising along when, all of a sudden, as i went to accelerate, my vehicle instead began decelerating rapidly. i pressed the gas pedal, thinking i might have let up too much or accidentally had my foot on the brake. however, pressing the gas only caused the rpm to spike, with no change in my speed. i had to act quickly, paying close attention to the surrounding traffic as my car slowed down. thankfully, i managed to maneuver from the far-left lane to the shoulder of the highway. my speed had dropped to around 30 mph and was decreasing. trying to safely navigate a slowing vehicle on a highway filled with traffic is an adrenaline rush i wouldn’t wish on anyone. i was in a state of severe panic. as i steered the car onto the shoulder, i noticed it was shaking and struggling to move forward. white smoke was also coming from the exhaust. once safely stopped, i put the car in park and turned off the engine to let it cool down. after a few minutes, i restarted it and noticed the engine, oil, and battery indicators were all illuminated on the dashboard. my first thought was a battery issue, but the car was still able to turn on. however, the engine did not start. a notification appeared, stating the car was not in a condition to be driven. after receiving the car back from the hyundai dealer i was notified that the issue was due to fuel injectors failing. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

While driving on the country side, my car engine stopped providing power to the car and started making some noise. the engine rpm would fluctuate and increase due to downshifting but there was no power. luckily, the car had some speed around 50 mph, the road was slightly downhill and nobody was behind, managed to coast to a gas station half a mile away. the engine shut itself off after the car stopped. i was able to restart the car but it would shut itself off within 2 seconds of restart. car was towed to the dealership and i was told that it had a faulty injector. the injector was replaced a week later and i received my car back later.

On 4 occasions in the last 4 months when i push the gas my cars rpm will go up but the car does not accelerate. this has happened twice on the interstate when trying to merge with trsffic and twice in city traffic, once when making a lefthand turn across oncoming traffic and once just driving down the road. i have taken the car to 2 separate dealerships for a total of 3 times and they drive it a few miles and tell me they can't duplicate the issue. i just picked my car up today after leaving it for 6 days. on my way home the emergency breaking system activated for no reason slowing my car down on the interstate. both of these issues could get me or someone elas killed. i have not even had this car for 2 years and i am afraid to drive it. please help. i know i am not the only person with this issue because i can see others on the internet who also have been told that the dealership can't dupe the problem. even the dealership i just picked it up from said they had another car there with the same problem that they can't duplicate so there is nothing they can do.

For like the fifth time while i'm driving the car just dies. i can be going 55 i can be going 70 and the dashboard lights up like a christmas tree and the car just dies. i have to pull the car over to the side and i have to turn it off and restart it again. and then about 3 days later the check engine light will go away. this seems like a software issue but hyundai and my local dealer cannot help me i'm going to get killed in this thing. i can't take it on the highway i can barely take it down the street because it could go out on me while i'm driving and i could be in the middle lane and i could get killed. they tell me they can't replicate the issue but it's a software issue somebody needs to do something before i get killed. every single light on the dashboard turns on and the engine just dies. this is like the fifth time this has happened. i think this car is a lemon but no one will help me.

Since i have had the car, i would have to check my invoices for exact mileages, i have changed my brakes 4 times now. i only have 40k miles on the vehicle. this is very bizarre to me since i have owned a 2020 hyundai sonata sel convenience prior to this and never once changed the brakes. i have also changed my rotors once, resurfaced them another then, and i am in the process of changing them again. now to this day, my calibers are shot. they will take 2 months on back order to come in from korea. maybe hyundai needs to look into n lines in specific as i have read many people complaining about the same thing. it's 40k miles and i am just now needing to change my rear brakes, seems pretty reasonable. something is very wrong with this car.

During snow and icing conditions the forward collision radar in the logo gets covered up and becomes inoperable. this at the very time that we most need forward collision warning. it would helpful if there was electric deicing in the unit, much like the rear view side mirrors.

Fuel injection systems failed at 5000 miles cell 2 at 15000 miles cell 3 under warranty but although tech said other two would fail prematurely hyundai would not replace cell one and 4 as these failures happen suddenly without warning while driving i feel this is a serious safety hazard

The push button shifters do not shift gears, unless the brake is depressed. on a slight incline, it is natural to shift from forward to reverse without braking leaving the driver in the wrong gear. so i have often started forward expecting to go backwards. i accidently ran over a portable toilet trying to quickly reverse out of a driveway on a slight incline. i hope no one has run over a person this way. i have had other close calls. this system is far more dangerous than lever style shifters. even a little mistiming between brake and shift can leave the car going the wrong way.

I bought the new car on 11/21/22. there have been two incidents with the same cause. incident #1: on 1/25/23, while i was on a six lane highway with high speed traffic and rush hour level traffic, the car began to fail, with 'bucking', failure to respond to the gas pedal, loss of power, and difficulty steering. at that time, the check engine light also went on (it had not been on previous to the event starting). i was able to get the car off the highway, where it completely died - it would not move. it was towed. mileage at this time was 1,330 miles - the car was 2 months old. it was diagnosed that "cylinder #3 fuel injector is stuck open causing drivability issue". the likelihood that i would have been hit, by another car on that multi-lane highway with cars at high speed, and hurt or even killed is extremely high, if not certain. i did not file a report with nhtsa about the first incident (i was not aware of this service.) incident #2: on 12/7/24, while i was again on a six lane highway, high speed traffic, night darkness, rain, and rush hour level traffic, the car began to fail in the exact same way as in 2023, 'bucking', failure to respond to gas pedal, slowing, difficulty steering, etc. i was able to get off the highway before it completely 'died'. it was undriveable and had to be towed. there was no warning light prior to the event occurring. mileage at the time was 21,091. the probability, considering the rain, the dark, and the fact that i was on a 'super highway', that i could have been hit, hurt or even killed is extremely high. the diagnosis was 'tsb indicated #3 fuel injector be replaced." i do not have any of the old fuel injectors. in addition, i routinely - multiple times a week - have small children in this car. these events could have happened when i had a carful of small children with me. my routine schedule means there was also the high probability of others being hurt.

Twice within the first 26k miles i had 2 individual fuel injectors go bad. both times my check engine light came on in the middle of driving, and then my car would no longer increase in speed and left me stranded on the road. luckily, i was able to pull over to the side of the road. the random malfunction of the vehicle could’ve caused an accident or put my life, as well as the drivers on the road, in danger. when my vehicle arrived at the dealership, i was told that it was “because of the gas i was putting in my car”. i have never had any problems with any other vehicle when using the same gas, and have never heard of it from anyone else except from people with the same make and model as me. the dealership refused to replace the other 2 remaining fuel injectors because “they aren’t in need of repair” but acknowledged that i will just have to wait until the other 2 fuel injectors go bad and possibly be stranded in the middle of the road again. when picking up my vehicle after the seconds repair, i was told that my timing cover was leaking oil and that was repaired as well. when asked how that happened, the service center told me it was a factory malfunction. the first incident where cylinder 2 went bad was on 12/27/2023 at 13,143 miles the second incident where cylinder 3 went bad as well as the leaking timing cover was on 12/2/2024 at 25,890 miles

I was driving into work on a major road (about 45 mph) when my 2023 hyundai sonata stopped accelerating and my engine gave out. initially i thought i was accidentally pressing on my break pedal but when i realized i wasn’t pressing the break, i had just enough time to turn on my hazards and get out of traffic and onto the shoulder of the road. i was stuck between a main exit and the major road. my battery, oil, and engine lights came on (no service lights had been on prior to this incident) and my car was just very slowly rolling before it automatically engaged my parking break - which makes me fearful of what would have happened if i had still been in busy traffic. i could gotten very badly rear-ended. my car only has just over 5600 miles and i never had any issues with it before and kept up with the general maintenance. i attempted to restart my car to no avail and about 30 minutes later i was able to restart my car but there was a very strong vapor smell in the cabin of my car. i got my car towed to a dealership and was informed one of my fuel injectors was misfiring/gone bad - similar to many other incidents on this site. i asked the dealership if they were able to view the state of my other fuel injectors and was told they were unable to do that, so i am unsure if other fuel injectors will go bad in the future.

I bought this car brand new in november 2023, by february, the car started stalling on the streets/hyway. all dash lights would come on, the vehicle would stall and is no longer able to restart. this happened 4 time in 2024. when i tow it to the dealer, they always come back with the same answer. ''the ac motor power cable has been disconnecting leading to lose of power''. they have replaced it 4x but the same problem persist. it's very scary especially whn am driving in a busy road or when am driving at night in the middle of winter. am not sure how to move from here. thanks.

2023 sonata n-line, complete loss of power while driving on seven (7) occasions over the past year. in all cases above 60mph creating a dangerous condition to myself and fellow drivers while attempting to pull to the side of the road while rapidly losing speed. in all seven (7) cases, the dtc code is p065312. i have asked the dealership to note the recurring issue in my service records and i have reached out to hyundai, mostly so that if i am involved in a serious accident because of this issue, there is a paper trail for legal purposes. the dealership folks are nice but basically unless the car rolls into the dealership with smoke pouring out of the engine, they want to charge a diagnostics fee and keep the car for multiple days which isn't helpful because like most, i need the car and the issue is extremely sporadic. it is disappointing and i hope hyundai takes note and provides remedy for the issue sooner rather than later as this is my sixth (6th) hyundai vehicle and really do like the car otherwise. all incidents below: 01/23/2025 - 9531 miles 01/20/205 - 9128 miles 12/15/2024 - 5500 miles 12/13/2024 - 5374 miles 11/22/2024 - 2409 miles 01/12/2024 - 568 miles 01/08/2024 - 554 miles

Good afternoon. my issue is related to an existing recall that hyundai motor sent to me back during the beginning of january 2025 for a gas valve, tank inspection (replaced if necessary.) and ecu computer update. i've been to a total of 4 hyundai dealers and none of them have been consistent with this recall. the first dealer is "future hyundai" in concord, california. initially, i'd took my car there for both recall and sound coming from the gas tank and my fuel level dropping. i was told by a service advisor by the name of hayley, that it would cost a diagnostic fee to locate the issue. i didn't have the fees. but, seeing that the gas tank was part of the equation. it was free. the gas tank inspection was never done. i was told by hayley that the fuel valve was replaced. but they mechanics only done a quick visual. i wasn't reassured that my issue was resolved. so i'd took it to a another hyundai dealer. this dealer told me that part of the procedure is to take off the tank and inspect it. i didn't get that far because i was told that a tool that was used is used to take off the tank was broken. a bleeder tool. which doesn't make sense, because the tool is used for bleeding out air from the fuel system. "allstar hyundai." the last two of the 4 dealers, "san leandro hyundai" and "freemont hyundai", told me that my fuel pressure hose in my gas tank and had swelled up. san leandro dealer told me that my gas tank expanded. but the "freemont dealer" only mentioned the fuel hose. but never mentioned the gas tank. but decided to add it anyways. none of these dealers have been consistent regarding the recall. "freemont hyundai", the last of the 4, the service man told me that my tank is available. but his story changed from the time that i can get the job done 4 times. to having to have my car for two days before they can order the part. he'd order the parts, verified to me, when i was at my appointment. but now that conversation changed.

The contact owns a 2023 hyundai sonata. the contact stated while driving at various speeds, there was a loud sound coming from the rear end underneath the floorboard like a part slamming on the undercarriage of the vehicle. the contact stated that the fuel gauge suddenly indicated that the fuel tank was empty. the vehicle was taken to the dealer who diagnosed that the gas valve and electronic control unit (ecu) had failed. the contact stated that the gas valve was replaced, and the electronic control unit (ecu) was updated. after receiving the repair, the contact noticed that while attempting to accelerate, the vehicle downshifted before shifting to the desired gear and accelerating. the failure was most persistent while driving uphill. the check engine warning light was illuminated. the vehicle was taken to another dealer, all star hyundai (3950 century ct, pittsburg, ca 94565) who was unable to diagnose the vehicle due to not having the tool necessary to detach the fuel tank. the vehicle was then taken to another dealer, san leandro hyundai a carnamic car center (1066 marina blvd, san leandro, ca 94577) who diagnosed that the pressure valve was swollen and the entire fuel tank and pressure valve needed to be replaced. the vehicle was not repaired. due to the inconsistency of diagnostic results, the contact decided to take the vehicle to another dealer, fremont hyundai (43690 auto mall cir, fremont, ca 94538) who diagnosed that the pressure valve was swollen but had not diagnosed that the fuel tank needed to be replaced due to not finding a failure with the fuel tank. the manufacturer was not made aware of the failure. the failure mileage was approximately failure mileage was 75,000.

I have had this car checked out 3 times and on my way to the 4th appointment. i can be in the middle of the road or pulled up in my driveway the rpms go crazy shuts off every light comes on then clicks and i have to waite and try to restart. this car has been a problem since we bought it brand new even the chrome has come loose on it. took to 1 dealership they said it's not throwing a code so nothing they can do i pulled out of the dealership onto the busy highway and the rims went crazy lights came on and it died called the mechanic that said nothing was wrong he came out got it running took it back came back said nothing showing up so there was nothing he could do. i'm driving another 3 hours away hoping i make it to another dealership that said they would look at it after i sent pictures and a video to the mechanic. i will never buy another hyundai again and definitely tell anyone i know not to.

Similar to other stories i’ve read online, my 2023 sonata broke down on the highway a minute after any error signal popping up, in a dangerous location on the highway with no shoulder. plaza hyundai dealership was first/last and only people to perform an oil change or service the car. they told me they wouldn’t take the car due to being full after the incident. a different hyundai dealership took the car and found the breakdown was due to a missing oil drain plug and the engine leaked all the oil, while noting they didn’t do the previous oil change and there was no external damages. plaza hyundai is refusing to claim responsibility and just trying to milk me for much money as possible/get me to purchase a new engine.
