Headlamp wiring melted the headlamp module and bulb receptacle there was no fire but there could have been I was informed there was a service directive on this that expired on 12/31 but I still had to pay $240 to have it repaired when I googled the problem I found multiple complaints about this defect. I feel it is something you should look into.

Right headlight gasket around daytime running light overheated and melted headlight casing causing entire headlight assembly to need to be replaced. Did not discover until realizing daytime light was not coming on. Unsure of how long the issue had been going on.

Day time running light went out and the socket and housing melted.

- Virginia Beach, VA, USA

Passenger side headlight failed to properly function, bulb was changed and still failed to function properly. Problem seems rooted in manufacturer's wire harness not properly functioning.

Day time running lights burn out on GMC Acadia. Light gets so hot, they melted and burned the headlight assembly. This is a possible fire hazard. I have had the lamps replaced 4 times by the dealership, between both headlights assemblies. Less then 60,000 miles, the headlight assembly was so badly burnt and bridle, it fell apart in the technicians hand and it would not hold a lamp anymore. The whole entire headlight assembly needs replaced. The problem is caused by heat from the halogen lamps. An easy fix could be replacing the halogen lamps with leds. These are day time lamps only and are on all the time. This is a very poor design and craftsmanship by GMC and a safety issue they are not willing to correct. I have tried addressing the issue directly with GMC with no luck.

I have had multiple problems with the daytime driving lights over heating and causing the entire headlight assembly to melt. Incidences on 8-1-09 8-15-09 4-8-10 and 11-15-12. And again in 2013. The fact that there is enough heat to melt the assembly to the housing tells me there is possibility of a fire. This is obviously a design and mechanical flaw of the vehicle. The consumer end of this is that along with the chance of fire, the vehicle's design requires the entire front grill to be removed in order to replace the headlight wiring harness and housing. This labor intensive method means that replacing this part can cost upward of $900. And it still does not address the initial problem of the overheating that caused the wiring harness to melt into the housing. So you are just waiting for it to happen again and hope that it is within the 30 days warranty for repairs. And wondering if my car is going to catch fire.

Multiple problems with this vehicle. It has been in the shop more than 10 times in the past 4 years that I have owned it, frustrating. List of repairs: Timing belt, head lights, steering, camshaft, oil leak, struts, brakes and this is what I can recall mostly.this vehicle has had multiple services especially for service stability track that never gets repaired, they can't find the problem. Also service air bag keeps coming on but dealership cannot do anything while the light is not on. Very frustrated with this vehicle. I have never experienced so many repairs and services with any other vehicle as I have the Acadia. I owned a galant car before the Acadia for 5 years and only had to do one repair in those 5 years I owned it. I regret purchasing this vehicle! I am a single mother of two and I need a dependable vehicle not one that is malfunctioned!

I was taking my daughter to Florida for cheer leading competition; I was just outside of Illinois when the check airbag light and message screen came on thankfully the light went off but came back on on our way back to Chicago and kept coming on and off. Took it to dealer but they only said that the harness was tight they only wiggled it and light went off but came back a couple of days later. Then the power steering started making noise dealer said they didn't hear anything and didn't do anything and noise is getting louder. Then suspension stared it making noise. Took it to dealer and had tie rods replaced. Then the service airbag problem came back and this time didn't go away. Took it to the dealer and they said that the harness was to tight and they rerouted it so it wasn't tight anymore. Worked for a couple of days and its on again but I didn't take it back and now is past its warranty.then head lamp went out. Had to pay dealer $180 (rip off) next the other head light went out. My nephew replaced it in less than 10 min. Now there is a recall for that head light problem. Then wipers arm came loose from motor I had my cousin fix it for me. Now I have had the check engine light on for a couple of weeks took it to autozone came back with the code to replace the canister purge solenoid now I have the transmission problem, it started to act funny shifting pretty hard some times and then a few days ago I was driving on the freeway coming home when I notice the rpms at about 45000 and it wouldn't change gears and the fuel gauge started going nuts I don't know why and had to drive it home on the same gear. Took it to autozone and came back with the same code for the solenoid plus P0700/P0716/P0717 for the transmission. Now my Acadia is just sitting on my driveway no money to fix it and driving my 15 year old truck hoping GMC does something about this nightmare

Daylight running lights overheat both driver and passenger sides. There is evidence that both bulb sockets have overheated and the light housing has cracked from the overheating. With the bulb and socket overheating this has the possibility of causing a fire, with evidence being the cracked lamp housing form the heat. I have replaced the bulbs on both sides always using dielectric grease. I have owned this car since 2010 and replaced the right side bulb 3 times and now on the left side 4 times. There is a factory recall on other year models but not on the 2008 GMC Acadia slt-2 having every bell and whistle. It was Monday, Nov. 19, 2012 when this electrical system failure happened again.

My vehicle has an issue with the daytime driving lights and headlights. The lights have failed multiple times due to the bulb melting into, and fusing to, the headlight assembly. This created a condition where the entire headlight assembly needs to be replaced. This includes the lens piece, the bulb, and the wiring connector. This is an issue at night (no/misaligned headlights), the loss of the benefit of daytime driving lights, and I imagine a possible fire.

While it was raining outside, I was sitting in the back seat and happened to look up and saw water/ rain trickling out from around the rear interior overhead light, it was also coming in around the sensor in the overhead. The trickle eventually slowed down to a drip. In my opinion, water and electricity don't mix.

- Rosedale, MD, USA

The drl went out and we took it to the dealer to be replaced. They said the housing around the wiring/light had melted and we would need to replace the entire housing at a cost of $1,100. They stated it was a fire hazard. I am out of warranty and see that this is a common issue.

I replaced the driver side daytime running lamp and 8 days later replaced passenger side daytime running lamp. The last bulb replaced was on the passenger side and now is burned out again less than three weeks later. There is evidence on both bulb connectors of overheating. Dielectric grease has been used everytime bulbs have been changed through out the life of the vehicle. To the best of my knowledge, any time there is overheating on an electrical circuit further problems could arise. There is a factory recall on other year models but not on the 2008 GMC Acadia slt-2 having every bell & whistle along with higher price tag than lesser trim packages.

Low beam headlight out. Have changed twice within a 2 month period. Second time I changed it went out the very next day.

Headlight failure due to faulty wiring in headlight assembly.

- Colorado Springs, CO, USA

Passenger side headlight doesn't work. Connector is burnt. Appears to be electrical problem and requires entire head light unit to be replaced. Not covered under extended warranty. Cost is ~$600.

2008 Acadia. Low beam lights suddenly stop operating while driving. Severe safety hazard. GMC forums on internet show hundreds of consumers experiencing same issue. Our low beam drivers side went out. Low beam passenger side two days later. Due to poor engineering, the lights cannot be accessed without removing the bumper or tires. Not a bulb issue. Problem with melted wiring harness. There was no to way replace the wiring harness without splicing the wiring and installing an aftermarket connector part. Possible fire hazard as the bulbs are too hot for the current wiring. The harness replacement will only fail again because the wiring cannot handle the heat. This issue can leave you stranded on a dark road at night with no headlamps that may just suddenly go out. This is a potentially serious and deadly problem. According to the many forums, this is a common issue on Acadias and Saturn outlooks.
