My engine light came on and I called On Star to diagnose the problem. They said it was possibly a leaking gas cap. Replaced it...was not the problem. Had the evaporative charcoal filter changed...not the problem. Had the dye put through the emission system and the local repair shop (Firestone) replaced four O2 sensors and the receiving end of the gas tank neck where the gas cap screws onto @ a the tune of $1300.00.....light came back on two days later. Now, right after I fuel up the damn thing doesn't want to start up. Have to wait about five minutes then it would start after one or two tries. Something has to be done, GM shouldn't get away with this......
