Saturn – All Models
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 Saturn. Though Saturn is the newest division
of General Motors (GM), some of the car’s defects have been around other
GM models for a long time. CAS has received complaints on common Saturn
defects such as engine problems, transmission breakdowns, water
leaks, and other body defects.
GM tried to do everything right with the
Saturn but missed several major marks. Despite spending $3 billion and taking
8 years to bring out the Saturn, GM failed to offer the one feature consumers
most wanted — i.e., airbags. Instead GM equipped the Saturn with motorized
front shoulder belts and separate lap belts as its passive restraint system.
Even Saturns with air bags still have this motorized passive belt system
which induces 70% of occupants to forget to use the separate lap belt. The
1991-92 Saturns both had failing passenger crash test scores. Not until
Saturn came out with a standard dual airbags in 1995 did it pass all the
An example of problem avoidance came in
Saturn’s largest recall of 352,883 1991-93 models for underhood fires caused
by a short circuit in the generator which led to excess current and overheating
in the wiring harness as well as generator failure. Rather than replace
the defective and more expensive generators, Saturn opted to change the
wiring from the generator to tolerate the higher current from the short
circuit leaving the owner to pay for any generator that failed.
Service bulletins issued by Saturn document
dozens of problems, including engine, transaxle, and other components. Manual
transaxles may pop out of fifth gear, and automatics have a harsh or erratic
upshift. On SC models, using the horn can cause the headlights to pop up.
The engine can miss, surge, backfire, lack power on acceleration, or stall
after start-up. Saturn notified about 1,800 owners of 1991 models that their
engines had incorrect coolant supplied by Texaco and that they would get
new cars. Engine problems continue to plague Saturn with 1991-97 models
needing new cylinder heads due to coolant mixing with the oil. Saturn extended
the warranty to 6 years/100,000 miles in June 1999, only for 1994-96s with
1.9L SOHC engines.
You’ll find more information on Saturn problems below and what
you can do about them plus a complaint box.
Your information will help us build a strong case against GM as we fight
for action on Saturn defects.
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 which entitles
