“My exact engine was as in a recall but not my car which failed prematurely at 84,000. I have taken extensive maintenance in the car in the for the past 2 years. Hyundai made me pay to tow my car to a dealership denied me for a goodwill replacement with the same exact problems as the same exact recalled engine and stuck me with the bill.”

NHTSA complaint #11768574, filed 2026-10

“The vehicle has 82.000 miles on it, and the engine started to rattle as I entered the street to my house, and the motor quit running. I had the vehicle hauled to a repair garage for analysis, and they said the piston rings failed. The vehicle is in perfect shape except for the broken engine.”

“At a stop sign, or red light, car bucks, then accelerates. Steering column is making noise. Took car to dealership..stated they can't look at my car until October 31st, 2023! My car only has 16k miles. If this is a dangerous issue, especially the steering colum noise (possibly a bearing issue or rack and pinion problem)..why am I having to wait until October??”
