“I was pulling into a parking spot and my vehicle suddenly lurch forward, and I had to slam on the brakes quickly, scraping the front of the curb. I checked there was no warning lights. I checked the floor mat, and this was not impeding the accelerator pedal I am certainly I did not accidentally hit the accelerator instead of the brake.”
NHTSA complaint #11732187, filed 2026-04“The dashboard error code (check vehicle power supply) also in the bluelink app the error code(DTC P1A9096). I was driving the car. It was 196 miles of range.

NHTSA complaint #11630270, filed 2024-12“The vehicle popped up a screen that said check power source. Then within 30 seconds went into limp mode said power was limited and couldn't drive faster the. 25mph in the middle of a highway. By the time I pulled over to the side of the road my car was dead. Ive been trying to get Hyundai and the dealership to dignose the issue. Based on the error codes I was given it appears to be a dead iccu and 12v battery. I am in a ioniq group on Facebook and over the last week of being in it I've counted over 50 dead iccu on this group alone. All in one week.”
NHTSA complaint #11712691, filed 2026-01“My Ioniq6 slowed down to 20 mph for the second time tonight. No matter how hard I pressed on the accelerator the car would not speed up past 20 mph. A message on the dashboard said “Limit: 20 mph”. Eventually the car picked up speed then said “Limit: 43 mph”. (The speed limit on University Blvd at this point was 35 mph). I did not test that, as I was almost home. This happened around 7pm on Saturday, Nov 18, 2023. My wife was in the car with me and asked why I was driving so slowly. The first time this happened, a couple weeks ago, I don’t recall seeing a message on the dashboard. …”
