The contact owns a 2005 GMC Envoy. While driving at an unknown speed, the interior and exterior head lamps failed simultaneously without warning. As a consequence, visibility is significantly reduced, which increases the risk of a crash. The vehicle was taken to the dealer numerous times, but they cannot determine the cause of the failure. He is in the process of notifying the manufacturer. The failure mileage was 26,000 and current mileage was 46,000.

I own a 2005 Envoy - 7 months after owning it - while driving in the dark all the sudden the headlights and dash/radio/mirror lights started flashing on and off. "like a cop car" to the point we pressed on star-afraid the car was going to stall on busy/dark freeway. When I called a dealer they said oh "that's normal" you had to much running and new cars can not handle "heater/radio etc. "its no big deal" > I called another dealer and they said no-this is a problem bring the car in. Ends up there was a bulletin for this and the chip had to be updated. Very wrong for the one dealer to say no big deal-when they know a update was out.
