Auto brake fault has been a constant issue with this 2021 Hyundai Ioniq Hybrid. This causes lots of system functions to stop working (adaptive crusice control, lane keeping assistant, etc.) The dealer originally replaced the wiring harness, but it came back again and again with the same issue. They finally figured out that replacing the rear calipers seemed to make it stop. They have done that twice and this past weekend the fault warning appeared again. So, for the 4th time, we will be taking the car back in so this error goes away. For additional details, I will give you the most recent time, but note that the other 3 times all happened with in the first 1-3 years of ownership.

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.

The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
