Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I am a teacher and got a call in my classroom that my Suburban was on fire parked in the parking lot. The fire department was called and when I got outside, sure enough there was smoke all in the Suburban and smoke coming from the roof of the vehicle (not the hood). When the fire department arrived, they entered the vehicle, disconnected the battery, and proceeded to tear out my rear headliner to extinguish the electrical fire that was occurring. …”
