One problem related to engine failure has been reported for the 1998 Saturn SC2. The most recently reported issues are listed below.
I own a 1998 Saturn Sc2 and I have had many costly problems with it. On October 5, 2004 the engine failed because of a timing chain and now the whole engine will have to be rebuilt. Prior to this incident, the car has been consuming an enormous amount of oil. In March of 2004 I had to have the fuel injectors and O2 sensor replaced. I have had many expensive problems with this car.
