Example complaints

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

“I was stopped at a red light and was rear ended by a car going 40. The car started on fire in the rear of the vehicle and burned pretty bad. I have to get a new car due to the significant damage resulting from the fire, I'm just happy my kids weren't with me at the time. I have herniated and bulging discs in my cervical and lumbar, which were found by mri. Not sure what happened with this car but thought it important to let the general public know about it.”
