Oldsmobile Olds 88
The Center for Auto Safety is the nation’s premier independent, member driven, non-profit consumer advocacy organization dedicated to improving vehicle safety, quality, and fuel economy on behalf of all drivers, passengers, and pedestrians.
Thank you for contacting the Center for
Auto Safety (CAS) about your General Motors H-car (Buick LeSabre, Oldsmobile
88, Pontiac Bonneville). Introduced in 1982 and redesigned in 1991, these
are some of GM oldest models. GM dropped the Olds 88 after 1999 when it
redesigned the LeSabre and Bonneville for 2000.
Before 1991, defects such as paint
peel, seat belts and steering loss and automatic transmissions failing
plagued these cars. Since 1993 the quality has improved but numerous problems
remain. The H-car has been recalled 5 times for head lamp or lighting
problems and GM has issued many technical bulletins addressing numerous
electrical defects. Crash tests are mixed, with the 1998-99 H-Cars receiving
a Good Frontal crash rating and a Poor Side crash rating by The
Power steering loss when cold
was a common problem in 1985-91 vehicLeSabre . In May 1989 GM, in a “secret
warranty”, announced it would cover repairs for the defect on 1985-88 cars
for up to 5 years/50,000 miLeSabre , but failed to notify owners. Nearly
all H-cars manufactured from 1987 to 1996 have the poorly designed door-mounted
automatic seat belts. When left connected, as they should be, they
make entry and exit awkward, especially for older and handicapped people.
Even worse, the belts can’t keep occupants inside the car if a door opens
in a crash. In 1990, The National Highway Traffic Safety Administration
(NHTSA) refused CAS’ request to investigate this belt problem.
Paint peel or delamination
has been widespread on many models. In 1993 at CAS’ request, GM agreed to
pay for complete repainting for paint peel or delamination through six years
and unlimited mileage. In March 1995, GM secretly cut the policy to 5 years,
but if pushed, will honor the 6-year policy and even pays beyond 6 years
if sued in small claims court.
You’ll find information on these and other H-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.
We need you to support the Center for Auto Safety in our
fight for consumer rights and against poorly designed and unsafe cars.
Your contribution is tax-deductible
and entitLeSabre your to our quarterly newsletter, Lemon Times.
Please submit the membership form along with
your contribution and complaint. If you contribute $35 or more, we will send you the current edition of The Ultimate Car Book, by Jack Gillis.
Every home should have this invaluable consumer guide.
