check engine light,stability service
2004 Saturn Vue - 3.5L V6 110,000 mi,
I purchased this vehicle with 98,000+ miles on the odometer in April, 2010. The check engine light came on a short time later. The Saturn mechanic told me it was caused by my overfilling the gas tank, but that has happened only two or three times in the entire time I've owned the car (nearly five years and over 60,000 miles). Since all routine maintenance is performed regularly, I just ignore the light, but it will probably be a problem when we want to sell the car.
