It all started with my lights not turning off at night. I would have to disconnect my battery to get the lights to go off. Then the chimes would not go off. Disconnect battery again. Was told to replace key fob battery. A couple of weeks later, door locks, gauges, all dash lights, horn, headlights, went crazy driving down the highway with my 7 year old son with me. I have taken this vehicle to 7 or 8 places including the Pontiac dealership and noone knows what to do. Noone!!! my horn would blow intermittently sitting at a redlight one day, with two cars in front of me. The car immediately in front of me thought I was blowing at them because the light had changed and started to go, even though the car in front of them was still stopped. This is a seriously dangerous problem with the electrical system of this vehicle. The closest I got to a diagnosis of the problem was that it was a problem with the security system somehow. I just dont know what else to do.ad
