Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Passenger and driver seats in my 2000 Gmc Sonoma have seat positioning controls and locking mechanisims that do not always lock properly and/or get jammed up and have broken. A friend was sitting in the passenger seat and it failed to lock into place to keep it from sliding forward. I adjusted the bolts that fasten the seat to the floor of the vehicle to help 'realign' the seat frame so that the mechanism that keeps the seat from siding front and back would keep the seat locked into position once the seating distance is set. …”

The rear differential pinion seal was bad. It was replaced, but there is still a bad growl coming from the rear end when the consumer accelerates. The left door rattled, the right upper door hinges bushings were bad, there was no grease on the front ball joints, the front actuator motor for the 4-wheel drive was replaced.”
