Hyundai Ioniq

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…

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…

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…

I was driving my two young daughters (ages [XXX] and [XXX]) to school, in clear conditions, when we suddenly heard a static-like noise. Instantly, the car's check engine light and check EV battery light came on, and I realized I could no longer accelerate. I immediately pulled off to a safe shoulder and turned the car off and then back on. The car would not move. I exited the vehicle and THANKFULLY left my car door open. I walked around the vehicle and immediately called my husband for…

The vehicle has suffered a catastrophic failure of the hybrid drive motor rotor, transmission, and engine clutch, resulting in a $14,993 repair quote. This is a direct consequence of a failed remedy for NHTSA Recall 18V260 (Hyundai Campaign 176).In February 2020, a dealer performed an 'inspection/cap' remedy under Campaign 176. However, this did not permanently fix the manufacturing burrs on the hydraulic clutch actuator housing. Over time, the inner oil seals degraded exactly as warned in the…

VEHICLE SAFETY HAZARD: ACTIVE HIGH-VOLTAGE ISOLATION FAULT (DTC P0AA6) WITH DECEPTIVE DEALER/MANUFACTURER BYPASS & CONCEALMENT. On April 15, 2026, the dealer scanned my 2021 Ioniq EV and uncovered DTC P0AA6 (Hybrid/EV Battery Voltage System Isolation Fault), which denotes a catastrophic high-voltage leak into the chassis. This is a severe safety hazard posing immediate risks of fatal electrocution to occupants, EV battery thermal runaway (fire), or sudden total loss of propulsion at highway…

The vehicle was not repaired. The manufacturer was contacted. The contacted…

The contact owns a 2022 Hyundai Ioniq Hybrid. The contact stated that while driving at various speeds and while passing a nearby vehicle on the left lane or while a street sign was nearby on the right side, the vehicle would independently apply the brakes without the brake pedal being depressed. No warning lights illuminated. The vehicle was taken to a local dealer, where it was diagnosed; however, the failure was not identified. The manufacturer was made aware of the failure. The failure…

Installing a car seat and the belt buckle failed. The plastic part split and no longer holds the belt together. This was under regular pressure with standard leverage that the car seat design calls for. Nothing was ever on top of the buckle and it is not damaged in any other way at all other than the failure. They refused to replace it via warranty.
