Seven problems related to brake light have been reported for the 2003 GMC Envoy. The most recently reported issues are listed below.
Headlights and brake lights went out at same time. High beams work, vehicle runs, has all powers. This happened when I left the house, while driving, noticed when it began to turn into early evening.
To whom it may concern. 8/29/2012. I bought a used 2003 GMC Envoy xl sle/slt and purchased the vehicle from sherman of skokie IL. About this vehicle. The third brake light piece that covers the top of the rear window basically fell off the car on a windy day. The plastic piece that holds the third brake light broke leading to the entire piece falling off hanging by the 2 wires that connect for power. I live in algonquin IL and recently have seen three other Envoys with the same missing third light piece in a period of two weeks. I have looked up recalls for this vehicle but surprisingly have found none. Knowing I have personally seen several Envoys with the same missing third light piece I think there needs to be a recall. Not only is this a safety hazard but it's the law to have a third brake light in illinois. I have not brought to a dealer since there was not a recall and I do not have the out of pocket cash to pay for this to be fixed. Respectfully I would like this third brake light piece replaced and fixed at no cost to me. I do have the third light piece that fell off to give back to you so you can inspect it. I would like this fixed within 30 days of receiving this letter. I would appreciate your prompt response to this safety hazard and thank you for your time. This is the letter I sent GMC and they said there is nothing they can do!.
While driving @ 35 mph I noticed a very loud rattle and heard a noise looking in my rearview mirror a saw the whole plastic top that fits over the hatch back and houses the third brake light, fly off into the air and land in the other lane of traffic. It ripped the brake light wire right out. Luckily no one was coming around the turn at the time. Had to stop traffic to get it out of the road. This is a busy side road that comes to a stop light.
: the contact stated the brake lights were loose and became inoperable. A NHTSA recall, #04v527000 was performed on the vehicle concerning, the exterior lighting; brake lights however; the recall did not remedy the problem. The dealership would not offer a second repair under the recall.
: the contact stated while driving 70 mph on the highway the brake light on top of the rear window fell off. The dealer was alerted. Updated 9/20/2006 -.
: the contact stated, there have been four failures to the exterior turn signals as well as the brake lights. The vehicle was taken to a dealer for a recall notice where the exterior lights were replaced, but the problem continued. While driving at 35 mph, the left turn signal was engaged before making a left hand turn but the exterior light would not illuminate. The failure of the exterior lights resulted in the contact's vehicle being struck on the drivers side doors causing minor damage. No police report was filed.
Faulty wiring in brake light caused vehicle to catch on fire. Gm has offered to repair but I still don't feel it is safe.
