Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Traveling at a speed of 30 miles per hour at a low RPM, I heard a loud grinding noise underneath the car. Initially I thought road debris was caught underneath the car and I was dragging it along while driving. I quickly turned the car to the right off the road and turned the motor off. Underneath the vehicle I noticed all of the engine's oil spewing out from the bottom of the engine. I contacted my insurance company and arranged for a tow vehicle. I thought an object struck the undercarriage of my car. …”
