Dear GM Owner:

Thank you for contacting the Center for Auto Safety (CAS) about your Geo
(Prizm, Storm, Metro or Tracker), or Chevrolet (Nova, Spectrum, or Sprint).
These models are made by Isuzu, Suzuki or Toyota. When GM introduced them,
they were sold as Chevrolets; later as Geos; and now as Chevrolets again!
As a joint venture car produced with Toyota in Fremont CA where its twin,
the Corolla is made, the Prizm (formerly Nova) is the most reliable with
the others falling much lower in reliability.

Brakes, exhaust, body hardware and integrity have generated the most consumer
complaints. The National Highway Traffic Safety Administration (NHTSA)
has conducted many investigations of defects and generated numerous recalls
on Chevy/Geo models. Even the Nova/Prizm has had four safety recalls.
GM has recalled Spectrums three times for fuel system defects that can
cause fires. GM recalled 1993-94 Trackers for rear axle shaft fracture
that can cause the wheel assemblies to separate and 1994 and 1999 Trackers
for steering shafts that separate. GM recalled 466,902 1989-91 Tracker/Metros
& 1990-91 Storms for defective Takata seat belt buckles that unbuckle
in crashes. GM recalled 211,306 1990-92 Storms for steering wheel hubs
that fracture in crashes and interfere with airbag deployment. The 1990-94
Metro sedans and coupes have door-mounted automatic belts that can't keep
occupants inside the car if a door opens in a crash.

Engine defects on these subcompacts include oil consumption on the Spectrum,
coolant leakage on Sprints, and loss of oil on Trackers. Many service
bulletins discuss various leaks and noises. GM informed dealers of these
defects, but never told owners. If you paid for repairs, try to recover
them through Better Business Bureau (BBB) arbitration; you can arbitrate
if your car is less than 5 years old and 50,000 miles. Otherwise, use
small claims courts to recover expenses. Many owners have succeeded in
getting compensation from GM through these avenues.

You'll find information on Chevy/Geo defects below and what
you can do
about them plus a complaint
. 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 entitles 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.
