Exterior lights will not come on. I work nights so it's imperative my lights are in good working condition. Driving 65 down a highway in the middle of the night and your lights shut off is a scary situation. I noticed a recall for this is under development. I'm not sure what that means and would appreciate clarification.

It was dark- almost 9:00, I turned my car on, everything stared fine, lights came on automatically as normal. Then I started driving came to a red light and they just went out, both of them at the same time. I was confused, I thought maybe somehow the switch got bumped so I was frantically turning the knob trying to get the lights to come back on. I couldn't understand what happened. None of the settings worked, not automatically, manual. I pushed the fog light button and those came on fine so I kept those on and turned around and went home. My husband and I then tried to find the source like a bad fuse but all other lights are workig, blinkers, highbeams, breaklights, reverse lights, interier lights, fog lights. We have not been able to get them back on.

Low beam lights failing intermittently. Lights shut off twice @ 9:30 pm on 5/16/2015 driving on divided highway at 65 mph. The lights started operating normally after pulling off on the shoulder both times. Researched the web and found this is a problem with probably the headlamp driver modules or relay. Drove the SUV to the GMC dealer today and they said they had no record of a recall for this unit and any work done on the problem would be billed to me. I left the dealer and called GMC and had them pull up this unit on their system and got the same run around. They finally told me that some 2007 GMC Envoy are being recalled for this condition but not mine. This is a scary condition and due to an extreme safety concern I purchased the relay at an auto parts store today for $38.31 and installed it myself. This problem is probably more wide spread than GMC has reported.

Headlights failed causing lights to go out while driving. Only the bright lights will work. Some kind of electrical malfunction. From my research, there have been many others.

I took my vehicle in for an oil change and the shop noticed that my brake lights did not work. I left the shop and decided to investigate the problem myself. After replacing all of the bulbs and discovering that the problem was elsewhere. I took the car to a dealership and they found that the problem existed under the dash, they determined that every time I hit brakes, the wires were being stripped and caused a short.
