The Auto Hold and EPB orange warning lights have been a recurring problem with our 2022 Hyundai Ioniq. We first noticed the car exhibit a jerky/jolting hesitation after accelerating from a complete stop which was reported to the dealership with confirmed paperwork at ~52K miles. The Auto Hold and EPB orange warning lights have been documented via photographs and video on been active at mileage ~58K and 72K, but the dealership could not reproduce (or scan the codes?) the warning light signature or jerking motion. Additionally, the car indicated that is was trying to either activate or deactivate the Auto Hold function even when the car was in motion and is never turned utilized by any driver of the vehicle. Even though this problem was described as hazardous and may cause the brakes to lock leading to an accident. Finally at ~88K miles the dealership was capable of properly diagnosing the problem and replaced the left rear caliper with CPB motor.

The Auto Hold and EPB orange warning lights have emerged for the second time on this vehicle after fixing an initial Auto Hold/EPB problem at mileage ~88-89K (tracking number assigned by NHTSA for this issue was 11761449). The mechanic stated this feature can malfunction in the error mode leading to unprompted braking in a previous conversation. After taking it into the dealership for review, it was revealed that a different wheel's braking machinery was compromised and needed to now be replaced making it the second repair of the same part on first the left rear now the right rear wheels. The first occurrence of the second warning light emerged ~94K. Of note, we purchased another Ioniq and have just experienced the same issue for the second times in that vehicle at mileage ~31K and ~34K, so it appears to be a common defect in this automobile.

The Auto Hold and EPB orange warning lights emerged while commuting to work, which are associated with the brakes. The problem was diagnosed by the dealer because the other car we own is also an Ioniq and we have had two different Auto Hold problems noted with that automobile (NHTSA tracking numbers 11761449 and 11761458), therefore we sadly have experience detailing this defect. There were no issues with the car prior to the Auto Hold/EPB warning lights appearing. The vehicle has been inspected by the dealership and the part has been replaced.
