“The contact owns a 2021 Hyundai Ioniq Hybrid.

The vehicle was taken to the local dealer where it was diagnosed that the brake caliper had failed and needed to be replaced; however, parts were not available. The vehicle was not repaired. …”

NHTSA complaint #11484263, filed 2022-09, 19,000 miles

“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. …”

NHTSA complaint #11618338, filed 2024-10

“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. …”
