I have had my 2001 SL in and out of there for nearly a year for the same problem. I have given them well over $600.00 so far, in several different trips, to fix the same issue. An honest shop gave me the bad news that the main computer brain needs to be replaced, and only Saturn dealerships are allowed to make this repair. I took it back to the dealership and told them that, but instead they changed the oil and told me that it was fixed. They even charged me an $85.00 "diagnostic fee" for changing the oil. Needless to say, it is still not fixed, and I can't even get a return phone call.
I have a complaint in with Angie's List and with the BBB, and still no attempt to resolve this issue.
