The power steering randomly fails at low speeds. This has created several hazardous situations while making left hand turns with oncoming traffic and right hand turns at intersections with waiting traffic on the adjacent street. The car was repaired at a local shop by replacing the power steering pump. I was told this is a common problem and the new pump is a more robust design. The cost for the out-of-warranty repair was about $850.

The headlight went out and GMC quoted me at approximately $120 to replace. Husband attempted to replace it but you had to take off the wheel in order to get to the actual light. I gave GMC the go ahead to replace and they called me back and told me that the wiring had melted and that it would now be over $300 to do it. I told them no and made a complaint. They called me a few days later telling me they would do it but I had to pay $50 deductible (assuming they went through some type of warranty). It eventually became a recall and I am now looking into getting reimbursed for my $50. Noticed my car started over heating and took it into a mechanic friend, let us know that the water pump needed to be replaced this was at approx 45,000 miles. I did my research and the GMC warranty covered the cost. At approximately 56-57,000 miles the car started making a whining noise when driven slow or first thing in the morning when it was cold. Took it in to GMC to get it checked out and it turns out that the steering rack had a leak on each side of the wheels and pinions, and power steering pump needed to be replaced. Quote almost $1500 dollars. I could not afford that price so took it back to my mechanic to see if it would be cheaper. He ended up replacing the pinions and rack but said the pump did not need to be replaced and ended paying $600 out of pocket. I'm hoping that GMC will see that many of us are having the same problem and will make it a recall. I will not be buying anymore GMC vehicles. All I want is a reliable car that won't break the bank.

First problem was the timing chains needing to be replaced at 18000 miles. After that repair was made the gas mileage was averaging 11 mpg. It was a one year old car! after that, it was a multitude of problems. Steering rack/power steering replaced and 'fixed', electric stabilitrak lights going on and off, dvd player not playing properly. All things the dealer had said they fixed (after they whispered that I should not have bought an american car.) now the transmission is acting up. Rolling down an incline when I was trying to back out of a parking spot. The dealer told me it was fine and they could not duplicate the issues I was having. I've written two letters to GM corporate to complain about the sub-standard vehicle. They were helpless and will not assist in any replacement of the car. They even told me that this would be a difficult car to trade in considering the problems I have had with it. Who is kidding who? I would never recommend this car and hate to continually put my family in it.it is unsafe. Period.

Power steering went in vehicle going around a turn. Almost hit a tree. Complained to GMC about the danger and they did nothing. I have two small children and bought this for safety. I do not feel safe in this vehicle anymore! this has happened to several other 2009 Acadia owners as well. GMC knows about it, but has not recalled the vehicle or let people know the dangers of this.

2009 GMC Acadia; steering rack failure. This is the third failure since taking delivery of the vehicle in January 2009. Dealer will repair under warranty however, the replacement parts are clearly not fixing the problem. Possible loss of vehicle control when the rack fails completely and suddenly. More often, the rack will leak internally giving owner "time" to repair. NHTSA needs to investigate as the cars affected are numerous. They include the Acadia, the Saturn outlook, Buick enclave and a similar Chevrolet model (lambda chassis) that utilizes the same component. Additionally, what happens to consumers once the warranty expires and the repeated failure occurs once again? this is my third failure in only 32,500 miles.

I own a 2009 GMC Acadia fwd slt-1, the vehicle was purchased new. We had minor issues with the vehicle and until recently, were very satisfied with the build quality, performance, and the vehicle overall. While en-route to pick up our kids, the power steering appeared stiff. There was no power assist of the steering at low / idle engine speeds, which made slow maneuvering extremely difficult, if not impossible. The performance of the power steering became worse and worse, to the point where my wife felt unsafe driving the vehicle. She was uncomfortable turning at intersections, and maneuvering in slow-speed conditions such as parking lots. We immediately scheduled a service appointment with our local dealership. The service team advised us that the steering pump needed to be replaced. The dealership declined to repair the vehicle at their cost because it was no longer under warranty. The vehicle was purchased on 9/30/2008; it is only two and half years new with 46,491 miles. It is disappointing that the vehicle would require such a repair. You may or may not be aware that this defect with the power steering pump is being reported by many Acadia owners. In addition, there is an issue with the steering rack that was documented in a service bulletin. We informed the service area of the unusual noises but they stated that there is no clear connection with this repair. At this time, they recommended replacing the steering pump at a cost of $522.16. This is clearly a design/manufacturing part issue; GM should publish a service alert to warn owners of this known issue that can lead to serious injury if failure occurs.
