There is a potential fire hazard with the daylight running lights overheating before they burn out on both driver and passenger side. The bulb gets so hot that they melt the bulb socket causing an electrical fire hazard. The heat also has made the headlight housing brittle and cracked to where the socket wont stay in place inside the headlight housing thus causing the bulb to lay on the plastic causing a fire hazard. General Motors knows about this fire hazard because I have called it to there attention and because they have a customer satisfaction program #13135. They have also recalled some 2007 and 2009 to 2011 vehicles but not 2008 with the same problem.

Water leaking after rain storm down to floor mats on both the driver and passenger side. We had our windshield recently replaced back in may of this year, so I thought that this was maybe the issue and took back to the glass repair shop. Upon investigating further, they found that the issue was happening to many of the GMC vehicles on the electrical recall. I went to GM's website and entered my VIN and nothing about this issue on our personal vehicle. In our small community there have been two house fires, major damage caused by the electrical system ignition etc on GM vehicles. We do not want to be the next victim.

My GMC Acadia 2008 constantly stalls on me the issues started August 5 and has continue up to last night August 17th. While I'm driving the car would shut off on me and the check engine light would appear. I wont be able to restart the car so I had the car towed to the nearest GMC dealer. After paying for a diagnostic report the mechanic told me they could not find any codes indication the check engine light even came on. Last night I was scared because I left work at midnight after driving about 10 minutes the car started jumping then turned off and the check engine light came on in the middle of the street. I called on-star and they were dispatching a tow truck because the car would not come on. After 45 minutes I tried to turn the car on and it came on so I cancelled the tow truck service. This is a issue that's been happening for the last 2 weeks. I cant get the issued fixed because the last 2 diagnostic reports that were ran states no issues. I also had on-star run a diagnostic report right when the issue happened and they also told me they don't see any issues. I took a picture with my cell phone when the check engine light came on but no one seems to know the issues the SUV is facing. Everything stays on the radio the lights just the car shuts off and wont start for like 45 minutes to an hour. I've looked on different GMC Acadia forums and it seems I'm not the only person having this issue with this same make model and year car. Someone on the forum suggested I make a compliant at the ntsa.

The vehicle refused to shift out of first gear and the check engine light became illuminated upon pulling out into the roadway. At 25 miles per hour the rpms were 4000 and it just would not shift. We pulled over, called for help and were stranded on the side of the road with two small children. We were hours away from home, and had to call family from hundreds of miles away to come help. The vehicle after being turned off and sitting for a while did then return to normal operation when restarted. Vehicle was driven home and two days later the very same problem recurred. Going to trade in this pos before someone gets hurt.

When the ignition switch was turned on, the car started, but rather than return to the "on" position, the switch returned to the "off" position and the motor turned off. This has happened numerous times, but only one time when the vehicle was actually in motion.

Acadia 6-cyl

  • 48,001 miles
When first starting engine a loud pop would occur. Signals, clock, stereo, dome light, battery gauge stopped working. Chevrolet dealer replaced the stereo and amplifier ($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!

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.

  • 65,000 miles
Turned off vehicle when arrived home. Opened the door and realized car was still running, keys were in my hand. Put key back in ignition and jiggled, nothing happened, car still running. Turned key to middle and then to start, turned off again and car finally shut off. I tried to start again to see if happened and the yellow light (malfunction light) came on. This time I was able to shut off the car. Called dealer to schedule service for this issue and recall 14030 that I just received in the mail, they can't get me in until July 11th. A few hours later I went out to car to put Acadia manual and grocery bags back in vehicle, unable to unlock back door with remote. Tried to start car but nothing happens except clicking noise and the yellow malfunction light comes on. Odometer reading above is estimate because the car is dead, unable to view actual odometer reading.

So the window switches don"T work, when I'm trying to open the window it will open but then it won't close back, the steering wheel makes squeaking noises and most important the most costly thing to repair was the transmission. We purchased the car used with 53,000 miles on and after driving another 20,000 miles the transmission broke I had to pay out of my packet about 4,000 dollars for the repair I have two small children and when it comes for safety im not sure if we should keep the vehicle. When I'm reading all those recall issues I'm getting worried about my kids safety.

Bought this life altering mess of a vehicle in June 2013 with 77K miles. Since that time a wide spectrum of issues have arose and cost me for than just money. Windshield wiper quit working and needed to be fixed (I now see that was a recall) constant electric issues in using beeping, lighting up at inappropriate times, not registering a grown adult in passenger seat. Also, leaking transmission fluid. GM did cover that charge which was no help with the rear end that had to be replaced at a cost of nearly $3000. Transmission still (before leak "fixed") and after will read idle transmission hot at many times. Leaking water when we receive heavy rains. Leaking comes from drivers side airbag "label") I have been financially strapped because of this vehicle I had worked and saved so hard for just trying to keep my job! I need my vehicle to work and my life is at risk when I'm forced to get behind the wheel because of these issues that GM is aware of. With the money I've spent (I'm a single working mother with two young sons) because of GM turning a blind eye I am in dire need of the proper resolution to this year long devastation of preventable events. Please assist me in this fore I'm unable to go further with continuing to fix problems that thousands of other owners are having with the same vehicle. Thank you. In 2011 my children and myself lost our home to a devastating flood that rocked our city and as of Feb 2014 we were finally able to move out of the camper and get a home. I cannot prevent a flood and all the pain it caused myself and my children but I will not cease to fight for what it right. That is replacing my vehicle with equal, reliable safe vehicle immediately! after all, this was completely preventable and should've been fixed before now. Please help me. Thank you for your time.
