I have a 2006 Saturn
Ion and my brake light comes on and out when the car is in motion. It also comes on when I make a left hand turn. The light will either come on for abut 10 seconds, but lately within the last couple of days it has stayed on as long as 20 minutes before going off. I recently has my back brakes done (May) and have had a coil repaired that was causing the car to shut off. What could be causing this?
