This vehicle will all of a sudden start swaying from side to side and the stabilitrak light will come on. In addition, the transmission will suddenly seize up, losing acceleration and nearly causing a crash. The engine will also state that it is overheating, all of a sudden and the vehicle will shut itself off and smoke will start coming from the engine. This has happened while going between 35 and 65 mph. On the streets and highways. My children in the bucket seats in the back were sleep and their heads hit the window. They sustained injury. That was on a regular street and the speed limit was 35 mph. I was within or slightly under the speed limit when the vehicle started swaying unexpectedly. When the road is wet, it will sway from side to side on simple curves in the road. I have had the transmission replaced twice. Due to the safety concerns and fear of my family being fatally injured, it was around christmas time. I have had to park the vehicle. I have contacted GMC by phone several times with no response in return. I spoke with someone and was informed to report it to NHTSA. Maybe something can be done about this before a death occurs.

Stability track warning light keeps coming on I was told by my mechanic that it could be the sensor so I had it replaced with a factory brand GMC sensor and I'm still having the same problem. Also my passenger side air bag keeps saying it needs to be serviced but it's never been deployed and no one has an answer for why this warning keeps coming up the stability track warning comes on as I'm driving every time after about 10 to 15 minutes and the passenger side air bag warning comes on as soon as I start the vehicle engine. And also I have a problem with code P0700 it keeps turning on my check engine light and I had it fixed but it still keeps turning on. Rattling noise in idle

I was driving down the highway and the stabilitrak turned itself off and a warning light came on saying it was off and to service it.

I bought my 2008 GMC Acadia and not long after the check engine light came on. It was the timing chain. I had the Chevy dealership replace it which was almost $3000. About a year and a half later it has gone out again. And I can't afford another $3000. Now it's just sitting. Very up set about this.

This has been the most unsafe car I have ever owned. I can not even trade it in the get a safer car. We have come so close to having many accidents with this car. The steering just freezes up the engine will just shut down will driving. We have had the transmission replaced once and not it needs replaced again. We are not hard on our cars..I just hope it does not come down to having a accident before someone sees how bad this car is.. this happens off and on all the time hard to put the dates and times down when this happens, we take into a dealer and it does not happen with them or the cost is just crazy.

The lights are going in and out, and the high beams as well as the taillights are doing the same. I was told there is a short in the system. The steering system is making a very loud noise any time the steering wheel is moved. The stability lights as well as others keep coming on and off but when checked shows nothing is wrong.

Since I purchased the vehicle the service air bag light has been on, now the transmission hot idle engine light is popping on and also service the traction control light and service stabilitrak ligt is coming on. Me my family had taken a vacation to Florida and the transmission began to startle all the way back to Tennessee leaving us in a devastated situation. I was hoping there was a recall on the transmission and and air bags this is very dangerous as many others has complained about the same issues in the past concerning their 2008 Acadia vehicles this vehicle was in motion on a city expressway with a high volume of fast moving traffic. I went to auto zone and O' reilly auto parts to have check engine test and the following codes appeared dtc P2762 torque converter clutch, P0700 automatic transmission control, P0171 fuel control system. And computer error. I don't know if this vehicle ever me recall but I feel me my family could have been severely injured as the fast moving vehicle was coming behind us as our vehicle lost power and connection.

I purchased a 2008 Acadia in November 2016. The seller stated that they had to order a airbag and replace the old one. Alone with the seat belt. I didn't get the car until a month later. When I got the Acadia it was making some whining noise, wouldn't crank back up, rattle and clatter, dragging in the transmission like driving in a certain gears, noisy in neutral. Airbag, seatbelt and stability traction control light continue to come on. Needed a alternator and now the engine gone. I been having problem's with the car since I got it, and it been only 13th months. We were driving twice and the vehicle shut down on us on the in-state. We had to get it pull back home. Several times driving on the main highway and street it wouldn't go in great. I don't photos at this time. I would have to wait until tomorrow, to go outside and take pictures. When I got the vehicle the left driving side tire light continue to come on, still having problem's with changing the tires left back and right front. Don't know how many miles was on there. I tried to place an X N the seat belt and unknown other space, but it wouldn't let me.

I purchased a used 2008 GMC Acadia in May 2017 ever since I purchased this vehicle I have had nothing but problems I purchased this vehicle because my daughter is a senior in high school and I knew that we would be needing it to travel from state to state for college tours. Every since I purchased we have not been able to travel because of the continuous light to come on, continuous codes that comes on and it causes the car to run horribly I am spending $20-$30 a day on gas and I'm also noticing that the oil is just evaporating but I'm not seeing it on the ground I continue to take it to the mechanic he continue to fix things that the codes gives him. I'm still spending money and I'm still not getting any results I have not been able to travel in this vehicle because I refuse to get on the highway with my child and breakdown in the middle of nowhere. What we need to do is start a petition with GMC because if everyone is having these problems then it is a serious problem I am to the point where I am ready to start a lawsuit. I mean let's be honest what are we waiting for either us or one of our loved ones to die and is known death trap. There are so many recalls on this vehicle that all of them should be just called in and repaired apparently it's a problem with GMC assembling the vehicle and they do not want to own up to their responsibilities and it's not fair to us that I lives are at stake.
