One problem related to vehicle shudder has been reported for the 2002 Saturn SL1. The most recently reported issues are listed below.
Car has been taken back to Saturn for repairs 5 times and after the max of 2 days the problems were back. The car is not safe to drive and has been parked in my garage for now two years. Saturn is not willing to buy the car back through the wisconsin lemon law and by an inspector and myself it is a pure lemon. The car vibrates, idles very rough, and has the curious tendency to stall, lose power while driving at any speed. The car does not know what first gear is, the back end tells you of any bump in the road. Car has stalled several times when turning in a major intersection just love the sight of on coming cars and getting the finger and the horn. Not to mention the fear of going to the hospital for injuries, maybe not me, but maybe my passenger at the time in this car was 6, my daughter.
