The car began misfiring shortly after I purchased it. Had it repaired. Spark plugs and fuel injector caps replaced. It's been less than 6 months and again the check engine light is on and the car will not shift gears or accelerate. Extremely dangerous to n the expressway. I drive my children in this car! Car threatens to die when attempting to accelerate.

I have a 2009 gmc acadia. Was purchased in february 2015 from barker gmc dealership. First problem I had was in the first month of me having the vehicle it started to misfire so had to get the coils changed. Then my A/C is not working. In may it started making a clicking noise when I turn the steering wheel. Then end of june sometime and is still occuring it starts when I am going to turn after slowing down it's like my steering wheel gets stuck and is hard to turn. When I am driving at a slow rate or slowing down to turn somewhere that when my steering wheel wants to get stuck. Therefore most definitely poses a danger to family when they are in the vehicle to myself when driving and to others on the rode. This is my family vehicle! I have 3 daughters and 8 month old twin boys in there and I feel unsafe driving it. But I definitely do not have the funds to get these problems fixed and definitely don't feel it is my responsibility to pay for problems that gm knew about for what 3 years now! This vehicle should have never been on the gmc delearship car lot for sale with them knowing of these unsafe problems. I bought this acadia 2-3 years after this lawsuit was put against them and the people at gmc didn't even bother to tell me about it's unsafe problems with the steering nor did it come up with me checking on this vehicle. If I knew I could go after them to get my 5,500 that I put down on this vehicle and my money back for my car notes I have been paying since march of this year, I would!!! If they cared about the well-being of human life they would not still be selling any of the vehicles that are having these problems til they resolve them!!! There most definitely needs to be a recall. This is causing a safety risk for children, women, and men. Actions definitely need to take place on this matter.

Vehicle had a slight misfiring when climbing incline. We replaced two spark plugs. Misfiring calmed down. A couple days later misfiring resumed. Husband was driving daughter to daycare when car had multiple dts codes appeared (stability track, check engine, reduced power) with car suddenly stalling while on a highway leaving barely enough time to coast off the road and out of the way of traffic traveling 60mph. Gmc refused to assist us on this issue until we found online a tsb about the timing chain which had broken. Due to the constant misfiring (direct result of the timing chain) two of my catalytic converter became clogged. Those have now been replaced out of my pocket however when driving vehicle home while it does run smoother it now misfires all the time even when not going up hills and idling very low and misfiring while idling. I am scared that while driving my vehicle this may happen again because the issue has become worse.

At approximately 90,000 my engine began misfiring. I took it to a local shop where they performed a full tune-up and replaced all of the plugs. However, there were also coils that were bad and had to be replaced. A week later, my check engine light came back on and the acadia was missing again. I took it to another shop where they showed me that the plugs were already charred and needed replaced again, and there was another coil pack that needed replaced. A few days later the check engine light came back on and a co2 sensor was going bad so I replaced it. A few days later the check engine light came back on and the gmc dealer told me 2 of the 3 catalytic converters were bad and needed replaced. My check engine light is still on and I'm just waiting for the thing to explode while I'm driving it. After reading other similar complaints about power steering and engine problems with acadia's, I'm convinced a major investigation into these vehicles and their safety needs to be launched by the gov. Now there is an air bag recall and in the past have had headlight recalls, water pump recalls, and who knows what else. The whole fleet should be declared lemons!

While driving on the highway my service engine soon light started to flash. It stopped so I continued driving until I arrived home. It was diagnosed as premature timing chain wear due to a faulty oil monitor sensor and it was "repaired". The issue has continued to happen since and the vehicle has been returned to the dealership 3 times to attempt repairs. It was at this point that I started to research this vehicle and found out that gm knows of a random misfire issue after engine removal (mind you this was to repair damage due their faulty part to begin with). They don't know how to fix the issue--it can be electrical or you could replace just about every part under the hood and see if that works. But no guarantee that this will fix it as I stated earlier, they don't know what will fix it. I do not feel safe driving my family around in this vehicle any longer. We live in the north--hence the reason for an awd vehicle--and I don't want to get stuck somewhere, in below 0 weather with my children in the vehicle. I now own a very expensive vehicle that I don't drive far as I don't know what it is going to do. To me this is a safety issue and liability that they have tried to sweep under the rug like the rest of their issues of late.

Bought used 2009 acadia in 2011 with 55000 miles and nothing but headache 1) 60k miles: liftgate came crashing down my wife's back while getting the groceries. They should have some safety measures to stop the gate from crashing. 2) 70k miles: truck wont start in drive way. Towed truck to dealer and they changed fuel pump. 3) 70k miles: engine misfire code. Replaced one coil. 4) 76k miles: coolant always low. Dealer changed water pump. 5) 76k miles: truck hesitate and feel a misfire between 45 and 55 MPH. Took truck to dealer and they quoted me over $3300 to replace all coils, spark plugs, steering wheel column and steering rack busing. 6) since we bought the car we cant even drive it with the windows down or the roof open. The truck shakes roughly with both roof and windows open.
