Buick Skylark

January 2000

Dear Consumer:

Thank you for contacting the Center for Auto Safety (CAS) about problems with your General Motors N-car (Buick Skylark, Somerset; Chevrolet Malibu; Oldsmobile Calais, Achieva, lero, Cutlass; Pontiac Grand Am). First introduced in 1985 as the Pontiac Grand AM, Oldsmobile Calais and Buick Somerset Regal, N-cars have undergone a bewildering array of changes over the years. In 1986 the Somerset Regal became the Somerset and was joined by the Skylark. In 1988, the Somerset was dropped and the Calais became the Cutlass Calais. In 1992, the Achieve replaced the Cutlass Calias but was cut after the 1997 model year when GM brought out the Oldsmobile Cutlass (just plain Cutlass) and Chevrolet Malibu. The Alero debuted as a 1999 model. CAS has received thousands of complaints on N-car defects such as power steering loss, stalling, sudden acceleration, paint peel, engine fire and failure, and automatic transmission failures.

In January 1992, GM announced a “service campaign” to correct stalling on 1986-87 N-cars with 3.0 V6's. The policy was in effect through December 31, 1992 or 100,000 miles, whichever came first but, consumers say that “service kits” GM used to cure stalling don't help. GM documents have linked two dangerous N-car defects, sudden acceleration and surge, to engine computer and cruise control malfunctions. GM has conducted four recalls on fuel line defects that can cause fires. All mid-1987 through 1994 N-cars have GM's door-mounted automatic belts that can't keep occupants inside the car if a door opens in a crash.

Among the N-cars' most expensive defects are engine problems: the 2.5-liter has had cracked heads and blocks (1985-86), valve guide wear (1987), and timing gear noise (1985-90). GM has had so many problems with the “Quad 4” engine that it extended the warranty to 6 years/60,000 miles, waived the $100 deductible on 1987-91's and notified owners about defective head gaskets. on 1992-93's, the “Quad 4 engine” had cracked heads and coolant loss for which GM extended the warranty to 7 years/100,000 miles. Other expensive defects include automatic transmission failure (1985-90), loss of power steering when cold (1985-88), and electronic dashboard failure (1985-88). Another expensive defect on 1985-92 N-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 more information on these and other N-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.
