For several months, my leased vehicle will suddenly stall while driving or not start at all. This often leads to me suddenly stopping the vehicle in traffic. I am 5.5 months pregnant and cannot continue to operate this vehicle in this condition, as it is a risk to both my safety and the safety of my child. I have communicated my concerns about this several times to the dealership, with the only resolution offered to me being to pay to lease a new vehicle. The check engine light has continuously been lit, despite service appointments. I have only been advised that there is -??no solution yet-??.

This is regarding recall number: 203 nhtsa:21v-301 My vehicle failed this recall inspection and has been with the hyundai dealer(Hyundai South Bay Torrance) for the past 2.5 weeks and I still have not heard anything regarding the remedy. The recall letter says that the engine would be replaced but the hyudai dealer said that the hyundai corporate office has not replied to them and it could take months to fix this. This is irrational as they have kept my vehicle and there is no guideline on when i will get it back.

- Gardendale, AL, USA

There is a recall on my 2020 Hyundai Elantra that I was notified about on June 28th 2021. I called the dealership where I purchased my car and was told that since there is no remedy for the piston oil ring that there was nothing they could do until a remedy becomes available. My car has been hesitating when accelerating and that is one of the signs of my car affected by the piston oil ring. I was told that if I continue to drive the car I am taking a risk of damaging it further. According to the NHTSA website It says the remedy is to have the whole engine replaced and they are not going to fix the recall until a remedy becomes available on their end.

Hyundai has failed to remedy the engine manufacturing defect for the past few years. Hyundai has not been able to remedy the engine defect in the 2.0 nu mpi engine in a timely manner. The Hyundai dealership, Tipton Hyundai sold me a dangerous, unsafe car with an engine manufacturing defect. The correct remedy for the engine 2.0 nu mpi defect is a buyback program issued by Hyundai.

Vehicle engine seizes and will not start. Happens multiple times. Towed vehicle to dealership and they state there is no recall for this problem however; NHTSA has a recall number of: 21V301000.
