I own a 2008 Aveo hatchback..@ 60,000 miles replaced timing belt. @ 75,000 miles after filling upwith gas @ Meijers, engine ligh came one.. Dealership replaced sensor. Now @ 106,500 miles, after filling up @ Meijers again, the engine light comes on again. Took to dealership.. *Thinking about getting timing belt replaced again.. The dealership said nothing wrong with car. Got oil change, picking up car tomorrow.. Should I get the timimg belt replaced asap? I drive 83 miles one-way to work three times a week.. Gas killing me, but get nealy 33 miles if I drive 60 mph.. What is the shelf life of the 2008 Aveo..?? I have an automatic trans.. Love my car... Need help and advice on maintence..
