Example complaints

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

“Heater core randomly cracked one day, causing a tear-like spill of anti-freeze through the top of the radiator. Car was taken to a mechanic and we tried welding the cracks. Anti-freeze still spilled out and anti-freeze smell came in through air events and the liquid also burned, causing smoke to come out from under the hood.”

NHTSA complaint #10193546, filed 2007-06
