2002 SL1 110,000 km I bought the car in 2006 at 50 months old ; 65,000 km. Saturn dealer told me, at my first service visit that the upper motor mount was worn & needing replacement. I figured that it should be a warranty repair - he said no. Then I asked why only 4 years 65,000 to wear out the mount. He replied that it was an aftermarket mount - poor quality. I then asked why the OEM mount wore out BEFORE 4 years 65,000 ! ..... to require an aftermarket - long before I bought the car. Errrrr.. hummmm. hemmm .. So long Saturn dealer. Question - at what point should I be concerned about the motor mount wear ? When I notice some sort of vibration ? What sort of costs would I expect for labour / parts ? Thanks ; John T
