The map lights go on and off over bumps. Took the car to the dealer and they could not duplicate the problem (although the mileage in and out on the service ticket was the same, so obviously they just hooked up their tester and called it good instead of actually test driving it to see it happen.) They returned the vehicle to me, and the very next time I drove it, lights going on and off again while driving. Could be a safety issue at night.
