We have recently taken in our Uplander into the dealership yet again but this time it was because the car would die in the middle of the road due to traction control, abs brakes. They changed out the computer brain and we had the battery cables replaced. And a week and a half later we had to replace the factory battery. Now, after that and more....we are experiencing the head and tail lights coming on randomly when the car is just sitting in the driveway not running, day and night. What is causing the headlights and tail lights to come on random when not in use?
