Filed Oct 31, 2026 · Brakes · AZ · crash

I was turning into a driveway and I had slowed down to do so. When I took my foot off the brake the car lunged forward at a high rate of speed. I didn't have my foot on the gas pedal. It happened too fast for me to respond. The car crashed into the side of the garage and continued accelerating and it drove through the garage door. No airbag deployed. I was the only person involved and I am uninjured. The car has not been evaluated yet as it is still in the garage waiting for the tow truck to pick it up on Monday. It will be towed to an auction place in [XXX] and Hyundai as asked to evaluate the car before anything is done to it. I have asked my insurance agent to arrange that with the auction house. There was no warning prior to this happening. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There are have been three significant safety issues with the car. 1. The forward collision alert system goes off without warning and with zero debris or cars in front of me. This has happened three times, putting my safety and those around me at risk. 2. The car has suddenly had what feels like the rear brakes locking up without warning midway through a turn. The car wheels were still spinning but the car stopped moving. This put me directly in harm's way. 3. While my foot was OFF the accelerator while I was approaching a stoplight, the car suddenly accelerated and lunged forward, nearly causing me to hit the car in front of me. I have taken the car in three times and called the dealership about this one more time and have had no resolution; they claim to be unable to replicate the issue. There were no warning messages prior to the failures.

On my way home waiting for the green light the car would not respond to the accelerator.. the engine would rev up on the tachometer but would not move. Finally the engine responded and the car took off reaching 83mph in a matter of seconds. After release of the accelerator I was able to get the car under control. At the next traffic light even with my foot on the brake the vehicle lunged forward nearly striking the car in front. I put the car in neutral and was able to use neutral and low gear to get it back home...the car was towed to the dealership the next morning.

According to the dealership where I bought this car, the ignition coil failed. This has happened two times so far, resulting in two separate trips to the dealership to diagnosis and repair the issue. They were able to reproduce and confirm the problem; however, what caused the coil to go out is unknown. The component has not been inspected by any other sources outside of the Hyundai certified mechanics at the dealership. No warning lights or messages appeared at time of occurrence; however the engine would rev up when switching between hybrid and gas modes causing the car to lunge forward. The car also would lose power and not accelerate placing me in extremely unsafe conditions as this has occurred on the highway both times. The car is currently at the dealership getting another ignition coil installed. The second time these symptoms appeared caused me to lose power while turning into a gas station from the highway almost resulting into a t-bone crash with a semi-truck. I purchased this car end of February 2021.
