“I have a 2003 montecarlo ss with a 3.8 engine. Recently within the last couple of months my security light has come on. Have been told it is the pass lock. In order to shut it off I stop the car shut off lock and unlock doors and the light goes out. I have also been told this could either shut the car off or not start. Big problem. It could come on while driving or stationary.”

When starting off from a stop position and making a hard left the service traction system light comes on and the trac off light comes on and the ABS light comes on and the car makes a grinding noise. Only does this at this time. The second complaint is the overhead driver control panel will not come on and then after driving a ways it will come on. When off the air or heat or defrost will not work. I have replaced it once and now it is doing it again. I have not done anything about the lights for the traction.”
