I purchased this vehicle in Feb. 2021. Shortly after my purchase I noticed the steering would tighten up randomly when turning corners making it very difficult to steer / control the vehicle. It also does this when parking. This has happened numerous times since I purchased the vehicle. I googled the problem and found some info dated in September 16, 2014 indicating GM's Special Coverage Adjustment - Loss of Power Steering Assist indicating the special coverage covers condition described for 10 years after 1st svc date (the Carfax I received said was 2.10.2011) or 150,000 mi whichever occurs first from date vehicle originally placed in service regardless of ownership. I purchased my vehicle from a dealership on 2.03.2021 - took possession 2.06.2021. My vehicle only has 73,676 mi on it. I reached out to general motors to see if they would assist with the problem since I was not aware the issue prior to purchasing and I am the second owner. They declined and told me to contact my dealership and work with them.

While driving, my transmission was slipping occasionally and then it became a daily occurrence and multiple times a day occurance. When it slipped, I could feel it and the rpms would increase. I took it to a local transmission shop and it turned out to be a 3/5 wave plate failure. The broken parts damaged the rest of my transmission and I had to have a complete rebuild. I was lucky that I brought it in to be checked as I found out that this issue could have caused the transmission to fail completely which could have put the occupants of my vehicle at risk of injury or death due to an accident caused by loss of power due to a drivetrain failure. I have also read that there was a recall for the same issue on the 07-09's and that recall was #14404 special coverage transmission clutch wave plate. I have also read that the same part was used in 2010 but that gm refuses to extend this to 2010 models even though 2009 parts were used. I have contacted gm and they are telling me that my VIN is not included. It should be since my vehicle was made in 2009.

I'm having the same issue that everyone is complaining about where I lose power when at low speed trying to enter or exiting a parking space. The steering wheel becomes very stiff. Gmc recall was for steering pump but is making customers replace rack and pinion stating its unrelated and if not replaced it will not honor the 10 year warranty on the steering pump replacement

While I was driving tonight my vehicle shut off in mid turn causing loss of power steering. Where this happened is a very busy intersection. I had to pull over and when I put the car in park and restarted it came on for a second then shut off again. Then was able to get it running again. I had my wife and 6 month old daughter in the car and this could have been a very different outcome. I have read many of complaints online about this same problem in these vehicles. I really feel that gm needs to take a serious look at this issue before something major happens.

My wife's gmc acadia shut down while driving down expressway and lost all power and threw a cel. The diagnosis from the dealer mechanics was a stretched timing chain. I was told this is common and a scheduled maintenance part but nowhere in my manual does it state this. Also I contacted gm corporate to see if I could get help it being a safety issue for the shut down and was told it was out of warranty and there was nothing they could do. My vehicle has approximately 149,000 miles now I have to pay over $2000 to fix a known issue but the real problem was the unexpected shutdown and loss of control in the middle of rush hour traffic in a rain storm. Fortunately my wife's quick thinking got her to safety but could have been much worse if she would have lost power in the middle of a busy intersection or an on ramp she could have been severely injured. I would like to see these problems resolved.

Check engine light: timing chains stretched. Check engine light came on. I took the vehicle to the local dealership where I have service performed. The service representative informed me this was a stretched timing chain issue - a common issue with gmc acadias. I was informed that if/when it "breaks", I can lose power to the vehicle while driving. I asked another repair center for a second opinion and while informing the service technician of having a timing chain problem on my vehicle (without providing make/model of vehicle), the service technician guessed that I had a gmc acadia as this was a common problem with them. I checked my warranties as I currently have 103,000 miles. None of my active warranties cover it. I called gmc directly and was informed by the customer service representative that they are aware this is an issue but it has not reached a level to which gmc will extend any type of special coverage for vehicles when this fails. Since this is an extremely expensive fix, I am stuck with deciding if I should go in debt fixing a 6 year old vehicle or risking it and driving it until it fails, potentially leaving myself at risk for an accident. This is ridiculous that it is a common issue that was addressed in 2007 and 2009 models but hasn't been addressed yet for the 2010 model.

The steering rack leaks and fails after the power steering pump goes out due to an internal failure. There is a bad design in the rack causing the car to lose power at low speeds and will cause bodily harm if not repaired. Gm knows there is a bad design of this steering rack and refuses to repair at their cost. They will only replace the pump when the rack is the biggest cost to repair.

I filed my initial complaint over the phone but I'd like to add a few more details. After getting nowhere with gmc corporate I did my own research uncovering there is a "class action lawsuit" (I have this document and can forward if needed) in place for multiple gmc vehicles for the steering issue. Gmc has publicly admitted to installing wrong size power steering pump! In addition, the power steering cable, a loose rivet in steering column, power steering fluid leaking, and/or no or low pressure all have been the sited as a "possible" cause! *my point being fixing all of these issues will cost owners thousands of dollars and most don't have this money. Gmc needs to recall this issue asap! Gmc has recalled numerous other non-lifethreatening issues with their vehicles. Loss of power steering when turning left on a main road or at any other time can and will result in serious injury or fatality!! This is serious and needs to be made a priority addressed asap!
