NHTSA Complaint #11457937 — 2021 HYUNDAI ELANTRA HYBRID

On multiple drives the car has "lurched" or accelerated when foot was NOT on the accelerator pedal. These were minor issues, but unnerving when pulling up to park near a structure. Today 3-23-22 I was driving and after about 1 hour of normal operation the car began to accelerate while pressing the brake, and decelerate while pushing the gas. The engine was revving and then slowing down opposite of what would be expected. This is a hybrid vehicle - it felt as if the gas engine was supposed to be spooling up to charge the battery but instead was feeding power to the wheels. there was no engine light illumination from this. I restarted the car and it seemed ok. Honestly, this was scary - trying to move from one lane to the next to an exit to safely exit the morning rush hour freeway. I had to keep my foot HEAVY on the break to make it slow / stop. On two other previous drives the vehicle "lurched" / the car "bucked" once or twice and then the gas engine would not re-engage. the MIL came on, and the car drove on battery power only. I drove off the road, restarted, and the vehicle worked fine. By the time i got the car to the dealer the MIL had cleared and they were unable to pull any codes and deemed the car safe / found no issues.
