Dear GM Minivan Owner:
Thank you for contacting the Center for Auto Safety (CAS)
about your General Motors (GM) Minivan. CAS has received thousands of
complaints on defects such as stalling, brake problems, engine
failure, transmission breakdowns, and door malfunctions.
Safety defects top the list of problems on GM's Minivans.
Crash protection is inferior on the Astro/Safari. According
to National Highway Traffic Safety Administration (NHTSA) 35-mph frontal
crash tests, the 1996-98 models produced a 25% and 34% chance of life
threatening injury for driver and passenger respectively. Earlier models
were even worse with drivers of 1985-92 Astro/Safari vans having a 78-96%
chance of death or serious injury in a 35-mph frontal crash while passengers
fared little better at 61-86%. The Chevrolet Lumina APV, Venture, Oldsmobile
Silhouette, and Pontiac Transport/Montana, while doing well in NHTSA's
35-mph frontal crash, had poor crash occupant protection in the Insurance
Institute for Highway Safety (IIHS) 40-mph frontal offset crash test.
In July 1999, GM announced it would conduct a "special policy"
service recall to modify antilock braking systems (ABS) on 2.4 million
sport-utility vehicles, pickup trucks, and vans including the 1992-95
Astro and Safari vans. Door malfunctions have plagued GM Minivans. The
sliding doors and liftgates on all of the minivans have had serious defects.
GM issued a special return program, GM Bulletin (33-10-55A),
for defective power sliding side doors in October 1993, for the 1993-94
Lumina APV, TransSport, and Silhouette. This program was in effect through
August 31, 1994. You may be able to still get GM to fix your defective
power sliding door for free if you were not notified or if you take GM
to small claims court. At CAS' request, GM has agreed to pay for complete
repainting for paint peel or delamination through six
years and unlimited mileage, but in March 1995, GM cut this back to 5
