Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving, a fire started inside the vehicle between the rear passenger side seat belt and the rear window. My daughters were in the back seat and started screaming. I immediately stopped the vehicle and ran to put the fire out by smothering and throwing water on it. There was zero warning...no lights or warning messages. No major injuries occurred (only small minor burns to my right hand). I then brought the vehicle to the dealership where it was purchased. I was told it was a known issue, and I was prompted to file a claim with my insurance company. …”
