Squeaking/whining in steering column. Dealership diagnosis, power steering gear leaking (rack & pinion) and must be replaced. Cost, $1432 plus tax. Vehicle has only 17948 miles. Not covered by warranty or manuf. Recall. Out of warranty due to age or time. Power steering could fail as it has in other vehicles. Definitely a safety issue. GMC should stand behind their vehicles as this is a design or engineering flaw. This condition is noticed when ever the steering wheel is turned in either direction.

The power steering stops working when trying to park or moving at a slow speed. I am in good shape and it takes me all my power with two hands to turn the steering wheel. There is no warning it catches you off guard and multiple times almost hit cars in spots next to where I park. We also have had the air conditioning fixed twice since we've bought it and still doesn't blow as cold as it should. The car has 78,000 miles.

At slow speed turns power steering seems to lose power assist

- Richmond, KY, USA

Loss of power steering at low speed. Had the entire rack replaced (prior to power steering loss), as well as the power steering pump replaced (after power steering loss and covered under the tsb) and within to weeks of having the power steering pump replaced, the exact same thing occurred. At very low speed, in a parking lot, making a right hand turn, I lost all power steering and heard a loud screeching noise as I attempted to maneuver my very heavy SUV to a safe area with no power steering. "service battery charging system" error came up on my in-dash screen and then it went away. I turned the engine off and re-started with no power steering still and then re-started again an that is when the power steering worked again. The entire time, the radio and lights were on and did not fail. I drove the car directly to the dealership and after a full day of having my car, they told me I needed a new alternator now at at cost of $1200!!!! I'm not sure how the alternator is related since I do not have electric power steering"!?!"! I feel like this defect is costing customers thousands of dollars for a defect from the manufacture and GM needs to wake up and issue a recall before someone is killed!!

My power steering has become increasingly loud and difficult to handle over the last couple of months. In researching this problem, I have noticed numerous similar problems other individuals with this type of vehicle have had. I am not understanding why there have not been any recalls to correct this problem if it is a common problem with the Acadia. Recently, approximately a week ago, I have noticed that my "stabilitrack" is off and my vehicle tells me to "service brake system" and is not becoming difficult to stop and shakes quite a bit when doing so. I travel from home to town and often have to travel on the interstate with multiple cars traveling in the same direction as myself in close vicinity. The power steering problem is roughly $1300 to fix and the brake system is roughly $800 to fix. Why are there not recalls on these problems if it is so common? GMC needs to be held responsible for creating poorly made vehicles that cost a ridiculous amount of money only for people to have to spend more money on to fix and my mileage is only 72,000 miles...these problems need to be investigated immediately before an accident happens, lives lost, and GMC sued.

I was driving down the road with almost 1/2 a tank of gas, and I lost power suddenly, and had no control over my vehicle because the power steering and everything quit. Because I am fairly strong, I was actually able to turn off the road into a safe place, and not be stranded on a very busy two lane road. After having the car towed to paul's automotive garage, I was advised that the vehicle was out of gas.

Whining noise in steering column, thumping at slow right turns, needed new rack and pinion, cv joints replaced

- Columbus, GA, USA

The contact owns a 2011 GMC Acadia. The contact stated that while driving at approximately 5 mph, the steering wheel seized. The vehicle was taken to the dealer where it was diagnosed that the power steering pump failed and needed replacement. The vehicle remained at the dealer for repairs under an extended warranty issued by the manufacturer. The vehicle was repaired but the failure persisted daily. The manufacturer was notified of the failure. The approximate failure mileage was 101,000.

- Bowie, MD, USA

The car started to make a loud whining sound 3 month after we purchased it used. Then power steering started to go in and out. Took the car to a auto care shop and this is what the bill said. "replace power steering pump, tried to flush system 2 times, bleed out air, replace power steering pump again, still no power steering." Spoke with GMC and was told to take the car to a dealership, we are covered under special coverage 14329. Going to dealership this week. We have already spent a little less then $1000 on this problem.

- Woodbridge, VA, USA

Steering wheel completely locked up during a turn a couple of weeks ago. Then last week I couldn't shift into reverse to get out of driveway. Had it towed to dealer. $1500 later I have new shifter and some sort of new gears in steering wheel. Looked it up and there is a class action law suit with millions of people having the same problem, yet still not covered under a recall. My vehicle only has 48000 miles on it this should not have happened if there weren't some sort of defect in manufacture.

Sterring wheel locked during turn

- Birmingham, AL, USA

Rack & pinion was leaking. Was replaced at dealership. Power steering pump also replaced. GMC did not make this public that there was a problem with pump. Replaced pump fluid with a different type than was originally installed. Many GMC veh. Have this prob. The fact that GMC changed fluids in the steering system could have caused the original to fail. GMC will not admit there is a problem with the steering system. Please check with GMC amd get the truth.

- Glenmoore, PA, USA

Had a loud whining sound coming from under the hood, the GMC dealer diagnosed it as the steering gear - replacement cost me $1840.28.

- Spring, TX, USA

I have a 2011 GMC Acadia at 43,000 miles it was brought to the dealer with a steering noise, which I was hearing when making turns in the vehicle. I was told that it is leaking from the steering rack and this was not covered under warranty and was quoted a price of $1,179 for it to be replaced. I have searched and found this to be a common problem with the Acadia's.

When traveling at about 35 mph, all systems failed -- steering, braking, electrical. The dealer indicates that this is a "catastrophic engine failure."

- Raleigh, NC, USA

After a short but heavy down pour, I traveled through a puddle at approximately 25 mph and lost power steering for 1-2 seconds. I was unable to turn the steering wheel and needed to brake to avoid going off the road. For the next 2 miles the vehicle seemed to operate correctly, but then it happened again at a slower speed (approximately 10 mph) as I tried to make a 90 degree turn on to my street. I was unable to make the turn and came to a complete stop, then the power steering kicked in again. Called the local dealer immediately upon arrive home and left voice mail (they closed at 5pm). Called GMC customer service and was told there is no know issue.

I was just told by the GMC dealer that my steering column is leaking fluid. Apparently, this is an extremely common problem, as it is all over every GMC Acadia forum as well as logged in your database. Why is a recall not being issued for this" it is obviously a design engineering or manufacturing defect. Why do we have to wait until there is a crash, injury or death before you are willing to issue a recall" this is absurd. My family is now spending $1,700 for this repair.

7/12/15 cincinnati, Ohio just as others here, I was notified by the tech that the steering gear/rack and pinion assembly required replacement due to power steering fluid leak. The dealership stated this would not be covered under a warranty and would cost $1200 and only the power steering pump has been recalled if steering fails while operating the vehicle. There seems to be many complaints regarding this issue with the 2011 GMC Acadia. Please consider taking the time to investigate these particular complaints. It very alarming to be informed that a reoccurring issue will not be resolved unless the power steering fails while operating the vehicle. It's also concerning that several consumers have experienced the same issue with power steering fluid leakage and malfunctioning steering gear/rack. This is a obviously a consistent complaint and should be addressed.

- Cincinnati, OH, USA

I was just told by the GMC dealer that my steering gears are not working and are leaking fluid. They said if it would have been the boot, it would have been covered under warranty. Apparently, this is an extremely common problem, as it is all over every GMC Acadia forum as well as logged in your database. Why is a recall not being issued for this" it is obviously a design engineering or manufacturing defect. Why do we have to wait until there is a crash, injury or death before you are willing to issue a recall" this is really frustrating. The GMC dealer quoted me $1,700 for this repair.

GMC sent a letter out saying there is a problem with the power steering pump and that they extended the warranty on it.in my case the power steering pump would quit at times and it had no power steering felt like manual steering. But before I could bring it in to get replaced it was leaking fluid which caused the rack and pinion to go bad. I explained this to the manager and he said the rack and pinion wasn't under warranty and I had to pay for this which cost me $1372 I sent GMC a email to complain and they called back saying the dealer would call me which they never have I left them a message to call me and a number to reach me but now nobody wants to call me back I think they want me to forget about this.I said a rack and pinion should not go bad on a truck with just 48800 miles on it and the power steering pump caused this which they should stand behind their product.
