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, Alero, 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.
