My service engine light, abs light and trac light stay on at all times. I have had it serviced with the result being "my gas cap was not tight. " I feel there is more to this than they say due to knowing 3 other Alero owners with the same problems.
Without warning caller hears a noise ,and at the same time, the bell sounds , and the dash lights come on. The lights that come on are the anti lock brake lights. The track off light, and the service engine light. For only a few seconds the brakes will not work. Has had wheel bearings replaced in the front, and is about to get it done again.
