Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Fuel line rusted out and leaked gasoline onto pavement, under driver's seat. This event was not caused by an accident, and did not cause an accident. This event did create a fire hazard, but it was caught in time. My car is in the dealer's repair shop 13+ days now and still awaiting repair, because the manufacturer (ford) has the new fuel line part on national back order and refuses to fulfill my dealer's order for a new part. Please help me get my car fixed. …”
