Wiring problems of the 2008 GMC Acadia

There is water that comes down into the wiring harness of all of the doors. I am able to take the wiring harnesses off and tons of water dumps out. This has corroded many of the electrical components. The corrosion has led to locks windows mirrors and speakers not working. Please recall this. . . . .

My 2008 GMC Acadia began displaying service air bag and turning off the passenger airbag intermittently when a passenger was in the front passenger seat due to the wiring harness under the passenger seat. After a few months it now stays on all the time. GMC said it's not under a recall but I have read several complaints about it with the same year make and model stating it's a recall this happens when in motion and while stoped.

Daytime running lights bulbs repeatedly burned out and now the wire harness has melted down. Fuse failed to trip. Damage has now been caused to the entire drl assembly (melting, see photo). Additionally I am concerned that whatever caused the bulb and wiring to melt will cause a vehicle fire and endanger my family. There are many cases of the drl bulb and harness melting, but my local gm dealer said there was no recall when I called to discuss the issue. Gm/Saturn released a letter authorizing paid repairs, that was valid from 2011-2013, but these vehicles are still on the road, and it needs to be a recall regardless of warranty status. The replacement parts have been recalled--gm knows there is an issue with these components.

The bose system in my 2008 GMC Acadia stopped working. I was unable to use the onstar system because there was not sound coming out of the speakers. Today we removed the wiring harness in the rear doors of the car and found water.

2 drilled holes in the sunroof are allowing water to flow throughout vehicle wiring harnesses. Water has settled in engine and harnesses. In my case, the water shorted out the amplifier. Worried that this could also create electrical fire or other malfunction(s).

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.

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.

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.

In 2011, our Acadia electrical system started to malfunction. First the driver's side headlight wiring burnt. We had that replaced. After the headlight, we started noticing the engine light was coming on and the air bag sensor was notifying us that the air bags will not deploy. None of the sounds where coming on in the car. For example, if you were not wearing your seatbelt the "dinging" did not happen. I took the Acadia in for service and they told me it was my cell phone that triggered the defect. I thank god I was not in an accident however if GMC knew of the defects why not be up front with us. My family and I travel plenty. Safety is the number one concern, we bought the Acadia faithfully and hopes GMC provides the best service possible.

When first starting engine a loud pop would occur. Signals, clock,stereo, dome light, battery gauge stopped working. Cheverolet dealer replaced the stereo and ampliifier ($1500 ). Then if I left Acadia in the rain I would find a small puddle of water on the floor under the emergency brake and a drop of water on the air bag on the driver side in front of the vehicle. Was told it could be the sun roof tubes were blocked so I took it to the auto glass place and had the tubes cleaned out. Very concerned about the water because I do not want to loose power in vehicle again. Just went on a trip and had to park outside in parking area and had a real puddle on my mat and underneath the mat. Today I called an auto windshield repair shop to see if the windshield could be leaking and was told that if the car was not in an accident or if it has not had the windshield replaced, they didn't think it would be the windshield leaking, that gm was good about installing and sealing the windshield. My car is kept in the garage and I am the only driver. It has never been in an accident and I am afraid that the wiring will short out, cause a soft spot in the floor, or start a fire. This automobile has only 69,285 miles and has been very well taken care of by only general motors dealerships. Serious problem involving wet elements and electrical problems here. Please let me know what to do!.

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.

The above odi id numbers signify existing complaints identifying water leaks and resulting damage in 07 & 08 GMC Acadias. Gm instituted recall campaign #08207: customer satisfaction - sunroof water leak-install drain tube extensions dated: Aug 27, 2008. Campaign was preceded by numerous tsbs linked to the same type of water leak. *** purchased certified vehicle on 3/4/09. TSB #08027 performed prior to certification and sale. Service manager stated water was present in the rear dome lamps and headliner. Returned to dealer 3/5/09 for water in the passenger floor area. TSB # 080857003a was performed. Prior title owned by a commercial entity and most likely never responded to these issues. Picked up vehicle on 3/6/09. Still taking in rain water. Took back to dealer on 3/9/09. Door seals replaced and returned on 3/11/09. Has not rained since this posting but concern is for electrical integrity on vehicle as water leakage was concentrated near main fuse block near kick panel and main wiring harness under passenger floor area. Mold is also a concern as dealer has not replaced carpeting or headliner but only cleaned affected area. Vehicle is used for transport of family over long distances and an electrical failure during on road use can be catastrophic.
