The contact owns a 2008 GMC Acadia. The contact stated that while driving at an undisclosed speed, the vehicle stalled without warning. The vehicle was towed to the residence. Wilkins Buick-GMC 6913 ritchie hwy, glen burnie, MD 21061, 410 999-1419, was contacted and the contact was informed that the engine and transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 142,000.

The timing chain broke which in turn broke the engine as well. It happened as I was exiting the highway, it just stalled and would not start again.

The contact owns a 2008 GMC Acadia. While driving various speeds, the "reduced engine power" indicator illuminated without warning. The contact stated that the vehicle's speed was reduced to 20 mph and the vehicle stalled. The contact was able to restart the vehicle after approximately 15 minutes. Quirk auto of bangor, maine (295 hogan rd, 04401) was made aware of the failure, but the source of the failure could not be determined. The manufacturer was made aware of the failure. The failure mileage was approximately 95,000.

Approximately 3 weeks ago, my 2008 GMC Acadia was serviced at 140,000 miles for worn out timing chains. Now, I am looking at problems with my transmission. How convenient. Within three weeks this vehicle has failed on me. The timing chains were rattling in turns when it was taken into the dealership and the problem was discovered. I actually visited and left the dealership several times before the problem was diagnosed, so I was riding around with a faulty part in my engine. The transmission went out after I had exited the interstate at which point I could not accelerate more than 10 mph. Good thing I was not on the interstate when it decided to stall out on me as I can only imagine how disastrous that would have been. The 2007 and 2009 GMC models were recalled for timing chain issues, never the 2008 model. The transmission problem is related to the 3-5-r wave plate, which had a 20,000 mile extension from gm to cover the repair if this broke, which of course I am out of, thus the repair costs for both defects are my problem. I do not understand how they will not back their products knowing that they are faulty. Gm needs to step up and man up to the fact they have inferior products inside these engines and transmissions.

Since 2011 my 2008 GMC Acadia has stalled on the highway and streets several times. The first major incident, the vehicle would not accelerate - thankfully I was at a stop light. The vehicle had to be towed and repaired. Then while driving on the highway, the vehicle slowed down by itself and would not accelerate past 25 mph. The first time GMC covered the repair cost done by a certified GMC dealership because the vehicle was still under warranty. The same exact thing happened 20 miles later (when the car was out of warranty) and GMC said they could not cover it because the car was out of warranty - but it was the same issue. All the times I have had this vehicle checked, I have been told it's transmission issues. Not to mention a whole bunch of other issues with this vehicle. This car is a huge safety hazard.

I have a 2008 Acadia and it just stalls out for no reason. This is a very unsafe problem and GMC -according to the dealer does not stand behind this wide spread issue. The dealer and GMC can't tell me what is causing it and they give me the vehicle back and say if it happens again bring it in and we will look at it but they can never find anything wrong. I fear getting in this vehicle because I never know if it is going to just stall out on me while in traffic on a major highway. There are numours posts on many web sites about this vehicle and how GMC will not help anyone. . Read more...

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!.

The contact owns a 2008 GMC Acadia. While driving approximately 45-60 mph the vehicle stalled. He stated that the vehicle stalled and within a couple of seconds the vehicle started moving in reverse. The following day, the vehicle would not start and the vehicle was towed to an authorized dealer. The dealer was unable to duplicate the failure. The failure occurred twice after the dealer could not duplicate the failure. The vehicle was taken back to the dealer and the dealer repaired the air bag light. The failure happened again on December 22, 2010 and the vehicle was towed to the dealer. The vehicle had not been repaired. The approximate failure mileage was 27,000 and the current mileage was 30,200.

On Aug 9th after leaving san bernardino CA. . I was driving up the cajon pass to return home. I had the car in cruise & gave it some gas so that I could get up the grade because there was a car behind me that was fairly close. As soon as I gave it gas the car lost engine power & I had to move over to the shoulder. The car came to a stop & I was unable to get it restarted. I thought it had overheated but looking back on the situation. I don't think that was the problem . I attempted to start the engine again after sitting for several minutes & it stalled again. I sat for several more minutes, tried again & it started . I stayed on the shoulder until it gained speed, & I was able to drive home. On tues. I called the dealership & they had me tow the car in. They were unable to find anything wrong with it. This is the only time I had a problem with the car.
