Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Replaced the transmission 4 times, recall on seats were fixed but bolts keep breaking so I bought new seats of a differnt style and replaced them after a 5 year problem. Paint has been flaking off the truck for appoximately 4 yrs and I cant get the dealer or GM to do anything with this paint problem. They say it is because I am the second owner. The truck was in an accident but the top of the cab and the bed is all that needs painted, and they were not damaged in anyway because of the accident.”
NHTSA complaint #10071252, filed 2004-01, 150,000 miles“Problems with vehicle slipping out of gear while driving. The vehicle went from drive to neutral while driving. The vehicle was taken to the dealer, who told the consumer that a new transmission would cost him $4000.00 and to rebuild an old one would be $3000.00. The consumer has made ongoing complaints about the vehicle and feels the cost of the transmission should be lowered. …”
