What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While my grandson was driving my 1998 saturn sc2, another vehicle hit the car on the drivers' side and the airbags did not deployed.
Upon impact the air bags never deployed. Prior to losing control the consumer felt as though the vehicle was accelerating as she was trying to brake. The cruise control button was switched to on but it was not engaged. Even after the vehicle had come to a complete stop the vehicle continued to rev as if in high gear.
At 60-65 mph driver heard a knocking sound. The noise level increased rapidly, then, engine stalled. Vehicle was in traveling lane on the highway, consumer exited vehicle, and ran to shoulder. Vehicle was rear ended by 5-6 different vehicles.
The master cylinder failed x2 resulting in my rear ending a jeep. The repair cost to the car and to replace the defective master cylinder cost me over $1500 out of pocket . This should not have failed in less than 70,000 miles.
Driver hit side left window & steering wheel. Then hit light pole. Air bags deployed. Driver was unconscience. The rear seat collapsed forward after being hit.
During the smog test, my car overheated but the temp. Gauge did not indicate it was hot. The temp gauge was registering that the car was running at it's usual temperature. I have always gotten my oil changed when I'm suppose to, and I've had the engine flushed to try and keep it in good mechanical condition.
Sun roof rails, after a great deal of research I have found the clips that the sunroof runs along to raise and return the window to its closed position, are defective. The company's answer to this problem is to sell you a very expensive replacement kit in which most of the parts are not even necessary.
Transmission shift cable, just broke while driving. After doing some research, I found this is a very common problem with the saturn sc2. The plastic ball that holds the cable in the shift lever commonly breaks.
