2021 Hyundai Ioniq Plug-in Hybrid

Auto hold/epb lights come one while driving. deactivates cruise control of on. turns off auto hold. ongoing issue with many reports but no recall or dealership knowledge. ongoing issue since purchase.

The "auto hold" feature on my hyundai ioniq malfunctioned, displaying a dashboard warning: "auto hold conditions not met. press brake pedal." this message randomly appears while driving or stopping, and it deactivates the auto hold and electronic parking brake (epb) functions. in some cases, the car rolls after stopping because the system fails to hold the vehicle. this issue compromises vehicle safety, especially on inclines or during stop-and-go traffic. it puts me, passengers, and other drivers at risk. the problem has occurred multiple times and is unpredictable. it appears to be linked to a faulty brake switch or sensor, as noted in hyundai’s tsb 23-br-001h. i discovered this issue is affecting many other hyundai ioniq owners, as seen in this discussion: https://www.ioniqforum.com/threads/auto-hold-malfunction.37797/ the dealer has not yet inspected the vehicle, but the symptoms match the tsb. no accident has occurred, but the safety risk is serious due to brake failure behavior. there were no visible warning lights before the issue started, just the "auto hold" message when the failure happens. i bought the car from a used car dealer when it had 39,000 miles. now it has around 74,000 miles. i’m not sure if it’s still under warranty. i haven’t taken it to the dealer yet, but the symptoms match exactly what other people are reporting online.

On a recurring basis, the warning lights come on for”auto hold” and “epb” or emergency parking brake. car continually beeps and gives warning until car is reset. during this time, the cruise control will turn off, causing safety issues during travel. also, the other safety features seem to stop working during the time this warning is activated. emergency stop, et cetera. only activated when vehicle is operating under highway mph. typically local roads with stops/starts trigger this issue. mechanics have no idea what is wrong with vehicle warning. i see online that this is a common issues with hyundai ioniq. a possible recall is needed to investigate/fix this issue as local dealerships arent aware of a solution.
