  • 80,000 miles


2002 Saturn SC1 lost engine--oil in coolant at 80,000 miles. The mechanic that disassembled the engine stated that the camshaft journals were worn so bad that the engine could not be re-built. Replaced engine 5 months ago, last week, auto transmission stopped engaging reverse gear. Discussed with local Saturn dealer who offered no help. This is my daughter's car. My car--2002 Saturn SC2 had to have an engine overhaul at 46,000 miles due to burned valves in #2 cylinder. Extended warranty covered repairs. Oil consumption prior to overhaul was excessive (qt every 1000 miles--dealer said normal) my automatic transmission has an intermittent extremely rough downshift, which was reported to Saturn dealers 4 times while in warranty. Each time, they said they could not duplicate the problem. Our family bought the car new, and recommended maintenance has been performed. At this time, I feel that Saturn has some well documented problems with both the single cam and twin cam engines, as well as the automatic transmissions.

On 2/1/07 my car started running rough, with no ses light coming on. After a couple of weeks the ses light came on and I took the car to the dealer for repairs. A defective intake manifold gasket had caused the rough idle, and the dealer said that if I left go to long enough it could have caused the engine to seize up. My car has only 37,315 miles on it and is garaged when not in use. A new intake manifold gasket was replaced for a cost of $463.44. I do not hot rod this car or abuse it in any fashion, I am 52 years old. If I had ignored the ses light I could have had an accident if the engine would have failed in traffic.
