Chevrolet Equinox 2013 74350 miles
Check Engine light came on after picking it up from the dealership after a connector was replaced. Taken in the next day due to it was after hours. They kept the car for 2 weeks, resetting the light and letting it run for hours at times and driving on the road. However no codes show up. They checked the gas cap when we dropped it off. However we had the cap replaced less than 3 months ago. Light is still on! But Chevy has no idea what it is. Any suggestions?
