Car was taken to dealership for inspection. Upon inspection, it was determined that the fuel tank had expanded and pushed towards the heat shield, and expanded upward pushing up the back seats of vehicle. It was determined to not safe to drive. Manufacturer contacted me and offered a buyback. Upon their offer of a buyback, it was determined that I would owe the manufacturer approximately $2,000. I have requested that they fix it, and they have refused to give me the paperwork I requested about the car's condition and fixability. I am in the process of negotiating and am filing this complaint for the record.

My vehicle while driving, it is jerking and shaking. When I come to a stop, the cars rpms go up and down while the car is shaking. When I pressed the gas pedal to accelerate the car will not accelerate as normal and the car jerks as I’m driving it. The RPMs rev up and down without any pressure placed on the gas pedal. The check engine light came on.The miles per hour only allows me to put one digit. I wanted to clarify that the problem is occurring anywhere between 0 mph to 65 mph when these the car jerks and shakes and the RPMs go up and down without me pressure on the gas pedal.

Seat Belts
07/01/2022
The seat belt latches do not latch or will spontaneously unlatch. This has been a problem for about 4 years. I have checked for recalls and not seen any for my car. I will check with the dealer but have tried vacuuming the latches without effect. I have never experienced anything like this in any previous vehicle. The warning buzzer lets me know when the seatbelt unlatches, but I seriously doubt the belt would hold in case of an accident.
