Example complaints

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

“Took vehicle to dealer to have oil change. Was told that they found needle bearings in oil pan. Car cannot be driven because needles may enter the engine and cause engine to seize up or complete engine failure. They had to replace 16 rocker arms, drain magnet,r and r oil pan to clean,change oil and filter. I believe these rocker arms failure is due to a defect in the vehicle as my car only has 16480 miles and is stored from oct. Through may. Car is one owner,me and has been taken for oil changes before driving in summer and again before storing for winter. …”
