What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While driving, the vehicle stalled. The vehicle was towed to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure recurred. While driving at 35-45 MPH three days later, the engine light illuminated again, and the vehicle started to decelerate.
Tire size: 225/4R18 88W Code 2119 indicates manufacture on 21st week of 2019. Factory original equipment on a 2020 Hyundai Elantra GT (N-Line). At the dealer for an unrelated service at approximately 37,000 miles. Tech noticed cracking on sidewall of all original tires. Suspects it is dry rot.
My 2020 Hyundai Elantra stalled on me in the middle of driving it. Only check engine light was on. Had an oil change three months prior to it stalling and not wanting to accelerate.
By June the car stalled in the middle of the street. Restarted it and was difficult to accelerate. Made appt with dealership, couldnt get me in until two months later. Continued having problems car needed more oil and did oil change in July. Continued to drive and it blew a hole in engine.
