I was driving my 2008 GMC Acadia slt in the evening, and when I switched from high beams to low beams, everything went black. I thought maybe my bulbs had burnt out, so took it to the dealership the next day. To my surprise, they discovered that the bulbs had melted the connectors, as well as the wiring harness, and everything has to be replaced.

My 2008 GMC Acadia passenger side head light went out about 2 months ago. I purchased a replacement light bulb and took it to my mechanic. When he took apart the compartment where the light is he found that the wiring harness that plugs into the bulb was completely burned and melted. There was no way of replacing the wiring harness without splicing the wiring and installing an aftermarket connector part. This weekend the drivers side bulb was out and again we had it taken apart only to find the identical problem with that bulb. In addition he checked on the other one just to see how it was working and found that the bulb is again getting too hot for the wiring and will likely burn up the harness again. The vehicle has been recalled for 2 electrical issues, the most recent being a circuit that could over heat and cause a fire. In addition to the headlight issues I have had my passenger side rear window wont roll down and the power rear hatch has started to malfunction and closes at random and if not careful will smash you if you are under it.

I own a 2008 GMC Acadia with melting headlights. The plastic housing is melting and the bulbs are melting into the sockets. I have had problems for many months with the electrical system including replacing 3 batteries in 1 1/2 years. I have had the vehicle checked by the dealer which finds "no problem" with the electrical system, and no explanation for the battery life. With intense heat that would be necessary to cause this socket to melt, metal and all, is of great concern, and is a potential fire hazard. This vehicle also was involved in a recent recall for possible fire with heated windshield wipers (now disconnected). Hopefully, this can be investigated, so that no one gets hurt.

My daughter sliced her hand on the jewel lamp inside edge of the rear taillight assembly on our 2008 GMC Acadia while getting in and out of the hatchback. I will try and sand it down, but the plastic edge from the mold is very sharp.
