Dear Consumer:

Thank you for contacting the Center for Auto Safety (CAS) about your Cavalier, Sunfire, Skyhawk, Firenza, 2000, Sunbird, or Cimarron (GM's J-Car). CAS has received numerous complaints on sudden acceleration, peeling paint, excessive oil and/or coolant consumption, poor engine performance, power steering loss, and transmission failure. Introduced in 1982 with the Cavalier, Cimarron, Firenza, Skyhawk and Pontiac 2000, the J-car holds the distinction of being the only platform shared across all five GM car divisions. GM dropped the Cimarron and Firenza after the 1988 model year followed by the Skyhawk after 1989. In 1995, the Sunbird became the Sunfire just as the 2000 became the Sunbird in 1985.

The reliability of GM's J-Cars is much worse than average. In fact, their reliability has been so poor that all but the 1995 Cavalier and Sunfire made Consumer Reports' list of "Used Cars to Avoid" since 1988. The Car Book lists steering, fuel system, and brakes as the three most common J-Car complaints. Engine problems, including cracked heads, surge or racing, leaking rear main oil seals, and piston knock, have also plagued these vehicles.

GM's door-mounted "automatic" belt system on pre-1995 vehicles cannot prevent ejection if the door opens while driving or in a crash. CAS petitioned the National Highway Traffic Safety Administration (NHTSA) to recall faulty "automatic" lap-shoulder belts and door latches on 5.5 million 1987-90 GM vehicles including the 1990 Cavalier, Sunbird. NHTSA denied CAS' petition. In 1992, more than 50,000 1991 Cavaliers/Sunbirds were recalled for defective shoulder belt guide loops.

Uncontrolled acceleration is a notorious J-Car problem that has resulted in 5 recalls of more than 300,000 vehicles. GM sent bulletins to dealers acknowledging power steering defects in 1982-88 J-Cars, secretly extended the P/S warranty to 5 years/50,000 miles and paid for post-warranty repairs for those owners who complain loudly. An expensive defect on 1985-92 J-Cars is peeling paint. At CAS' request, GM agreed to pay for complete repainting for paint peel and delamination through six years and unlimited mileage but, in March 1995, GM cut this back to 5 years.

You'll find information on these and other J-Car defects below and what you can do about them plus a complaint box. Your information will help us build a strong case against GM on the defects we know about and help us spot new ones.
