The vehicle was taken to a dealer where it was diagnosed that the headlight driver module needed to be replaced. The vehicle was repaired. The failure recurred numerous times. The manufacturer was not made aware of the failure. The failure mileage was approximately 117,000.

I purchased this vehicle 10 months ago and have to replace the headlights 9 seperate times not including the brake lights 5 times. After the 3rd time the man at the auto parts store stated this is a known problem with GMC> the lights get too hot and burn up the bulb and the connectors. I have had 2 buy now 4 rabbits connectors and they make the bulb last a little longer but the exspense is sad. If this is a known problem and it is posted all over the interent from customers with the same issues why has not recall beem placed for these lights. If it is heating hot enough to melt a connector that is a fire hazard and needs to be recalled. Now my speedometer stoped working and to my surprise I wass advised this also a common GMC problem with the cluster repair being required to fix it.

High beams on vehicle project straight up to the sky. When weather is clear it is not noticeable but when raining, foggy or snowing visibility is affected a great deal. My internet search indicated a problem with an aftermarket headlamp assembly but mine are GM stamped. This is definitely a safety issue.
