I was sitting in the passenger seat of my new 2023 Chevy Bolt EV while parked at a convenience station. The vehicle was on and not hooked up to a charger. I smelled something burning and quickly thereafter I saw smoke coming from under the driver side seat. The driver exited the vehicle and looked under the seat. The driver attempted to put out the fire with his hand and the carpeting under the seat. The fire got bigger. I ran to the closest extinguisher and pulled the pin to extinguish the fire. It was out for several seconds before re-igniting again. Another round of extinguisher foam was released and the fire was put out. I reported the damage to the dealership, the car manufacturer and my insurance company. I towed it to the dealership where it has been sitting since 6/1/24. Nothing further has been done since then. The dealership refuses to assess the vehicle and to date the manufacturer has not sent any inspectors to diagnose the reason of the fire. As A matter of fact my insurance company, the dealership and the manufacturer all advised me to get and pay for my own inspection from a 3rd party inspector which I am working on scheduling now.
