One problem related to back up lights has been reported for the 1998 Chevrolet Cavalier. The most recently reported issues are listed below.
#1, the front brake rotors warped and the pads were worn. Dealer refused to replace under warranty so I paid out of pocket. Now second set of rotors and pads is in need of replacement. #2 trunk lid latch could not be opened with key, dealer refused to repair/replace under warranty, so I paid out of pocket. #3 reverse light switch failed, again dealer refused to replace under warranty, I paid out of pocket. Switch has gone bad again and I paid to have it replace a second time. #4 driver's door hinges were bent and door did not always close tightly, dealer repaired at no charge. #5 driver's side side had a metal bar sticking through the upholstery into my back. Dealer repaired at no charge.
