NHTSA Complaint #11571954 — 2020 HYUNDAI TUCSON

I turned on a road that the speed limit is posted 55mph and I accelerated up to about 50 and suddenly my speed dropped back to about 10mph and the car began shaking and the engine light was flashing. There was absolutely no warning at all. I had left my house about 15 minutes prior and everything was fine while I was driving up until then. My engine failed. If I had entered an busy highway I would have most likely caused a Major Accident and been killed and/or killed others. It happened around 5:00 A.M. in the dark which was bad enough as I was alone on my way to work. I had it towed to the Dealership and they replaced the knock sensor and assured me that the car was perfectly safe now. But on Dec. 1,2022 I was driving on a 35 mph road and the car did exactly the same thing and I had to be towed again.This time after much arguing the engine was condemned and replaced.
