2023 Kia K5

I was driving with no other cars around, and i heard what sounded to be an explosion, come to find out my sunroof had exploded. i had glass fly all over the back windshield, and onto the road behind me. this could have caused an accident or damage to other vehicles if someone was around me.

Purchased a 2023 kia k5 in august 2022 and as of oct 2022 it has 800 miles. four times within that period when i was either stopped or coming to a stop the acceleration excessively increased to 4 or more rpms. i held my brake hard and put it in neutral in which the rpms got higher so i proceeded to park. the first 3 times (while in traffic) it lowered the rpms back down to normal. the 4th time (today) when stopped and shifting to park the rpms did not lower so while in park, i slowly took my foot off the brake and it slowly lowered the rpms. in all 4 instances i had the auto hold on. the 4th occurrence i noticed that the auto hold on the dash was blinking green then white so i turned it off. if this were to occur while i am driving at a high speed, i am afraid it will cause me to have a severe accident. please investigate if this has been reported in the past and act fast before there is a fatal result.

Mpg is lower then number provided by both dealer and manufactorer (my average 24 city 27 highway ) factoring that i rarely even use climate controls and other fuel consuming things and often turn off engine in mcdonald's drive thru lane

Wheel resonance ducting separated from wheel inside of the tire. broken pieces, threw off the balance of the wheel/tire resulting in very excessive vehicle vibration.

My wife was driving down the highway with her cruise control set to 75. she noticed she was only doing 71 and pushed the gas pedal manually. the rpm's increased to between 4000-5000 but there was no acceleration with the car. the car then dropped to 68 mph and would not accelerate at all. after pulling over and turning the car off and then restarting it started working ok. this seems to match the transmission recall of the 2023 kia k5 gt-line but this car is not currently included in that recall. this recall should be investigated and possibly expanded.

This is the letter i sent to kia: dear sirs, i own a 2023 kia k5 ex that i bought new and currently has about 8500 miles on it. today, while driving on i95 in florida, i had my right rear tire blow out. i could tell by the feel of the car that i had a flat before the systems warned me, but that is not why i’m writing you today. while i was working my way over to the right shoulder to stop, all of the waring lights came on and the brakes stopped working. now i want to be clear. it wasn’t a failure of the brakes themselves. it was not the anti-lock brake system. the brake pedal itself locked and would not let me apply the brakes. again, i want to be perfectly clear here. i am now driving on a 6 lane highway at about 50 miles and hour on three tires with no working safety systems and i cannot slow down the car. eventually, the brakes came bake on line and i was able to stop the car. however, if the traffic suddenly slowed down, as is common on south florida, i would have had no way to avoid a collision. i do not know if this is a programmed response to a tire blow out or a major flaw in your safety systems. if it was designed that way, fire the moron who designed it and have it fixed. if it’s a flaw in the design, have it fixed. i cannot believe how dangerous a car you let me drive. sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Went through automatic car wash, in neutral. the gear shifted and the car sped up, bumping the back of another car in front. no warning sound, and no auto break.

My sunroof exploded while driving on lakeshore drive. i hear a loud boom and i almost crashed. i thought it was my tire or something else look up its my sunroof, i could have hit some one or hit something. it hasn't been inspected or anything as of yet it just happened at 6:30am. this is crazy because there was no warnings no cracks no anything. i ride with my sunroof cracked open every morning. so i don't understand.

I was involved in a traffic accident on may 29 2023. i was hit on the passenger side sustaining $18,000 in damages. my side air bag never went off.

The car was 4 months old when i was trying to get home when all of a sudden i noticed all the engine lights started to go out. with a few minutes on the road, the car automatically shut down in the middle of the road. my head almost hit the steering wheel and i was so close to hitting another car. i tried to start the car but it wouldn't start, the engine was making a strange noise and it smelled like burning. i waited 45 minutes on the side of the road and started the car. i drove the car to kia and the fastest the car will go was 25 miles. when i got to kia i explained everything that had happened to the car. they did not assure me that the kia warranty was going to pay for everything and that they were going to investigate what was wrong with the car. it was a wiring issue and was covered under warranty. i brought the car home around 6:300 p.m. m. from the kia body shop and before i pulled out of the parking lot, i had the same problem again! the check engine light came on and the car came to a screeching halt again. i drove the car back to the body shop. i didn't tell him anything about what was wrong with the car. the car was serviced, however you should have no problem with a new 2023 car.

Was driving on the highway at roughly about 70 mph and all of a sudden heard a big explosion and found out my sunroof blew open with glass all over the back seat and inside of my car. luckily no one was in the back seat, if there was, they would have been injured very badly.

I was in a car accident on 6/30/23. i was side swiped and the front airbag deployed and exploded in my face, knocking me unconscious and leaving me with chemical burns. i had a grade 2 concussion so it's hard to remember a lot. i was taken to the hospital. and drivers and passengers from 3 other vehicles were also taken to area hospitals.

Tire: pirelli p zero all season m+s (235/45/18) tire experienced a catastrophic failure while driving entire tire came a loose from rim leaving the car incapacitated and unable to maintain control. luckily it was a rear tire which allowed partial control until able to safely stop the car.

Received an oil change as part of normal service schedule on a 2023 kia k5 vehicle purchased august of 2022 (from different dealership). 4 days after this service was conducted, the drain plug in the oil system of the vehicle fell out of my car, therefore draining my vehicle of the oil it needs to operate normally, causing the car to completely stall near my home. i had to pay out of pocket at a nearby express oil change facility to have a new drain plug and oil put into car, after which i immediately brought my vehicle back to this dealership to ascertain what happened. this is the second time this same exact issue has occurred with my vehicle (the first time occurring after an oil change at a different kia dealership in charlotte, nc), which i brought to my service advisor's attention prior to them beginning the oil change service. i expressed to this service department that i am extremely concerned there is something malfunctioning or defective within the vehicle that has caused this issue twice in an almost-new vehicle, and that i was now concerned there could be possible damage to my engine from this reoccurring issue. the service department at kia wesley chapel did absolutely nothing to address my concerns or the issue other than replacing the drain plug (yet again). this kia service department, and kia overall, refuses to recognize or admit to any issue within the vehicle, and i was told to "wait and see if it happens again".

I noticed several internal markings like streaks on the left windshield. i presented this issue to kia asap. kia service managers examined the windshield and refused to acknowledge that it was internal, possibly due to a manufacturing defect from a containment during the manufacturing process from the windshield company. they do claim that they feel pits on the windshield, which was due to another dealership scraping the object to see if it was external or internal. kia told me to file a claim with my auto insurance company and that it is not covered under warranty. i am concerned that the windshield integrity is compromised and a possible danger to someone hitting the windshield which could cause additional injuries from the safety glass deficiency.

Loss of power even hitting the gas. sputters and does not accelerate. had spark plugs changed thinking it will resolve the problem and it didn't. severe safety hazard even needed to get up speed

The contact owns a 2023 kia k5. the contact stated that the interior of the vehicle had an abnormal gasoline odor. the contact stated that the gasoline odor was inside and surrounding the outside of the vehicle. the vehicle was taken to the dealer. the vehicle was not diagnosed or repaired by an independent mechanic or the dealer. the contact stated the vehicle was previously taken to a dealer a month prior, but the failure could not be duplicated. the manufacturer was not made aware of the failure. the failure mileage was unknown. the vin was unavailable.

When driving my car will send off all dashboard lights, sounds. lose acceleration. pull over, rmps fly up and won. turn car off and turn back on to regain acceleration. engine light remains on. i know there is a recall for this for my exact car type, but the recall does not show up under my vin. after a phone call with nhtsa, i was told to report my vehicle to the website. my safety and others is at risk for obvious reasons. this can easily cause a crash. this happened once at 5k miles, dealership supposedly fixed it. but it happened again the other day at 19k miles. there are no warnings prior to my vehicle going into safe mode.

2023 kia k5 gt, 8300 miles. took car for 1st oil change and dealer said front brake pads and rotors need replaced. $800. the car is driven to school and home. how is this possible? brakes should not be worn out this fast! does this mean every oil change appointment will be $800 to replace brakes again. reading forums this is a common issue for this vehicle.

I was driving on [xxx] orlando florida on [xxx] doing approximately 70 miles an hour when a large explosion occurred out and within my car the whole car shook this happened twice within a 5 mile radius. the car was eventually brought to kia city in orlando, where they determined that the fuel system had failed . the valve had failed, and the fuel system tank and fuel pump had swelled and blew .this could lead to catastrophic explosion in the vehicle, and or someone catching on fire. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

Back number was replaced

Gas tank expanded and bent the undercarriage up so much it blew off the fuel pump cover and pushed up the back seat.

Glacier white pearl paint is faulty. chips and peals. simply driving the car and getting rained on caused the paint to chip and peal.

Why is kia dealership are allowed to sale cars that have recalls. knowing that they have recalls and are allowed to sale. why not fix the issues and then sale. safety concerns driving and have to kids in the back car 65mph and car shut down breaks don't work or accelerator used the emergency breaks had shut down the car. took it to the dealership i been calling them status on my car with no information provided. imaging being behind 18 wheeler my accelerator don't work. parts for recalls are out stock so why keep cars in the dealership knowing they don't have parts to fix the issues.

One day i was driving and my car began to shake really bad. it doesn’t transition smoothly when switching gears in transmission. sometimes it doesn’t accelerate and i’d have to floor the gas to get it going. rough acceleration. car would even shake in idle sometimes. it has been doing this ever since. one day it’ll shake, the next day it might not. it doesn’t matter if i drive slower or faster, the car still shakes, has rough to no acceleration, and shifts gears roughly. engine light is on and is reading misfire of cylinder 3.

I submitted a previous report nhtsa id: 11488746 and have not heard anything. i continue to have this problem and am afraid it could cause a severe accident. when i come to a stop with the "auto hold" engaged the acceleration increases to 4 rpms or a little higher so i hold the brake down hard with my foot in fear that the auto hold will not work. i proceed to shift it in park then as i take my foot off the brake the acceleration returns to normal. this is very alarming and has occurred to me at least 20 times since i've had the car. i have had the car in the dealership but they do not see anything wrong with it and does not register any error codes. the car has less than 10k miles on it.

I was driving down the road and i heard a loud boom noise and it was my sunroof burst it pieces. it was raining and it was not hot. nothing fell on it.

The contact owned a 2023 kia k5. the contact stated that while her son and daughter-in-law were driving, three loud bangs were heard coming from underneath the vehicle. the vehicle was pulled over to the side of the road and inspected; however, no cause for the banging sounds were found. the vehicle was then taken to a gas station to be inspected, but no cause for the sounds were found. the contact’s son then added fuel to the vehicle, but the fuel spilled from the filler neck. the vehicle was taken to the residence. the vehicle was then taken to a dealer where it was determined that the gas tank had expanded and damaged a part underneath of the vehicle. the vehicle was taken to be inspected after being deemed a total loss. the manufacturer was notified of the failure. the failure mileage was unknown.

Engine came on and off twice, car was smelling like gas and driving rough. tried to put gas in car and it would not take the gas, it wasted all over car. i checked my back seat and felt it was hard and sitting right so i looked under and the seat was lifted. after doing research, i learned i have an expanded fuel tank. not only that but there has been a recall on it that i was unaware of, i took the car immediately to the nearest dealership and they acknowledged there’s a recall and i can’t drive the car because the backseat can explode anytime now.

Heard and felt extremely loud bang under the car while driving then check engine light came on. vehicle had low power and the gas was decreasing severely fast. the backseat had moved with our 2yr daughter in her car seat above it. took it to dealership and they said the gas tank expanded and couldn't be fixed. they offered bottom dollar to buy it back

The contact owns a 2023 kia k5. the contact stated that while driving at 65 mph in hot weather, a loud popping sound came from underneath the vehicle. the vehicle lost motive power. the check engine warning light was illuminated. the contact coasted into a ditch and inspected the vehicle, but no exterior damage was found. the vehicle was restarted and driven to a gas station. the check engine warning light was no longer illuminated. the vehicle was taken to the dealer, but the cause of the failure could not be determined. the failure persisted and the fuel gauge level dropped while driving. the contact pulled over and placed a bag under the vehicle to check for fuel leaks, but found none. the contact stated that the vehicle failed state vehicle inspection due to an unknown emission code. the vehicle was taken back to the dealer, who performed an oil change and updated the computer system. the failure recurred while driving with three minor children in the rear seats. the fuel tank made a loud explosion, and the rear seats propped up, pushing the children forward while the seat belts restrained them in their seats. the child seated in the rear passenger seat received medical attention for injuries to the back of his legs caused by hot fuel fumes from underneath the seat, as well as black specks stuck on his legs. the contact's husband opened the fuel tank, and loud air pressure was released. the fuel tank was bubbling. the vehicle was towed to classic kia of carrollton (2920 n interstate 35e, carrollton, tx 75007), who determined that the fuel tank needed to be replaced and requested that the manufacturer send an engineer to inspect the vehicle. the vehicle was towed to the third dealer, huffines kia corinth (6940 s interstate 35, corinth, tx 76210), where an engineer determined the vehicle was non-repairable due to the fuel tank expanding in multiple locations and bending the sub-frame. the contact was informed that the fuel tank was manufactured without a pressure release valve. the vehicle was not repaired. upon investigation, the contact stated that the 2021-2023 kia k5s were not manufactured with a pressure release valve. the manufacturer was made aware of the failure and three cases were opened. the manufacturer offered to buy back the vehicle and reimburse for medical and vehicle rental expenses; however, the contact declined the buyback because the offer was less than the original agreement. the failure mileage was 17,857.

Component or system failed: the fuel tank exploded, causing the vehicle to become undrivable. the explosion was so severe that the back seat was completely blown off. the vehicle is currently not in my possession, as it has been with the dealership for over three months. i have photos and proof of the damage, and i am willing to provide them for inspection. how safety was put at risk: i have a [xxx] son who sits directly above the fuel tank in the back seat. when the explosion occurred, the back of his seat was completely blown off, and had he been in the car at the time, he could have been seriously injured or killed. this was an extremely dangerous defect, and i am deeply concerned that this could happen to other kia vehicles, putting more lives at risk. beyond the immediate danger of the explosion, i have been left without a working vehicle for over three months, and kia has provided no resolution. despite confirming that the vehicle is not repairable, they have stalled the process, forcing me to continue making payments on a car i do not even have. problem reproduced or confirmed by a dealer or independent service center? yes, the kia dealership confirmed that the vehicle is not repairable and that the fuel tank failure was severe. however, they have not provided any solution or compensation. has the vehicle been inspected? yes, the vehicle was inspected by the kia dealership, which determined that it was not repairable. i do not know if it has been inspected by any third-party mechanics, insurance representatives, or other authorities. warning lamps, messages, or symptoms prior to the failure? there were no warning lights, messages, or other symptoms prior to the explosion. the vehicle was operating normally before this occurred. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

The contact owns a 2023 kia k5. the contact stated that the rear passenger's side chrome trim extending to the trunk had separated from the vehicle. the contact related the failure to tsb number: sa552. the contact was concerned that the failure could cause a road safety hazard. the dealer and the manufacturer were not notified of the failure. the vehicle was not diagnosed or repaired. the failure mileage was approximately 13,500.

The contact owns a 2023 kia k5. the contact stated while driving at approximately 70 mph, the transmission unexpectedly downshifted, shuddered, and there was an abnormal sound coming from the vehicle. the electronic stability control warning light was illuminated. the vehicle was taken to a dealer where it was diagnosed that the transmission needed to be replaced. the vehicle was repaired; however, the failure persisted. the manufacturer was notified of the failure. the failure mileage was approximately 18,000.

I was involved in a head on collision, all of my safety warning notified me but my airbags never deployed. this is a serious safety hazard especially with many problems being reported with airbag deployment. the adjuster and collision center both stated at the rate of speed from the accident, the airbags should have definitely deployed. my car was deemed a total loss from the damage even without the deployment.

The back chrome cover around the rear windshield all 3 pieces are coming loose and i had the one on my passenger side fly off while i was going down the highway and the piece almost hit the truck behind me thankfully traffic wasn’t to bad on the highway so he was able to hit his breaks and maneuver out of the way before. i currently have 2 more pieces trying to come off. after doing further research i have seen hundreds of other post from k5 owners years 23&24 all having the exact same issue of the chrome pieces coming off and or flying off while driving. in the pictures you can see the one missing piece and the other 2 you can see where the other 2 pieces are starting to loosen up. if you physically touch it they both will move and feel loose. i believe this should be a recall before one of the pieces fly off and cause a accident by hitting another car like what almost happened in my case or just flying off and hitting a person. i bought my car used but it was a single owner my car was a little over a year old i’ve personally had it for i believe 10-11 months and i keep it in the carport daily so i shouldn’t be having these issues already.

2023 kia k5 gt1, once at 16k miles and now again at 26k miles, while driving, the dashboard console flickered on me and the car lost complete acceleration and power, fortunately on urban roads or else would have been extremely unsafe and dangerous if high speed, especially since i have a child. pulled over and turned off vehicle, and turned back on acceleration regained but check engine light remains solid. took it to dealer at 16k miles and they checked it out and just reset the codes, advised if it happened again to bring it back right away. i am aware of the open recall on this kia model, but my specific vehicle vin is not impacted. however, i suspect the sudden power loss issue is the exact same issue. this is an extremely dangerous and unsafe issue with this vehicle, particularly if you have kids or are driving high-speeds on the highway!!!!

While driving, thankfully not with my [xxx] son, the vehicle made a real big bang noise and lost power. looked back and the whole back seat was lifted. towed to dealer and tech found that fuel tank had expanded and exploded seat back. incident happened in november 2024, and to this day, kia has been the most difficult to deal with. they offered to buy vehicle back, but we have been waiting for a long time for answers and resolution of this issue. its impossible to get someone on the phone and we keep getting the run around with a loaner/rental while trying to continue to live normal life going to work and dropping kid at school information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

The national highway traffic safety administration (nhtsa) received a letter dated july 13, 2022, petitioning the agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain hyundai motor america, inc. and kia america, inc. vehicles spanning model years (my) 2005-2021. the petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. the petition itself can be reviewed at nhtsa.gov under odi number 11481745. on september 12, 2022, the office of defects investigation (odi) opened defect petition (dp22-003) to evaluate the petitioners’ request. the petitioners have provided additional complaints within four supplemental letters dated january 31, 2023, march 21, 2023, may 23, 2023, and august 4, 2023. odi’s evaluation included the review and analysis of the complaints and supporting information submitted by the petitioners, as well as additional complaints submitted directly to nhtsa which referenced either the oil drain plug or a crack in the oil pan. after reviewing the available data, odi has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. if during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. an improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing.  there is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. in october 2023, hyundai published a technical service bulletin (tsb) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. after a thorough review of the material submitted by the petitioner, the information already in nhtsa's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, nhtsa does not believe that a formal investigation is warranted. therefore, the petition is denied. a federal register notice (frn) further detailing nhtsa’s reasons for denial of the petition will be published. the reference numbers for the complaints to nhtsa cited by the petitioner can be found in the petition submission documents in the public file for dp22-003. to review those complaints and the additional complaints odi added to its evaluation which are cited in the closing resume odi report identification number document, go to nhtsa.gov.
