Having problems with your 2006 GMC Sierra ?
Gold colored light is on, my wife is driving the truck, says it is a geometric figure with two handles.She is afraid to turn the key off and reset it, because she is afraid it will not restart.
Sounds like the check engine light. Usually just an emissions warning such as loose gas cap. If the vehicle is behaving normally don't worry too much about it.
