Four problems related to power steering fluid have been reported for the 2010 GMC Acadia.
While turning at an intersection at a relatively slow speed, the power steering failed momentarily (approximately 3 seconds) making it impossible to smoothly correct the turn. Fortunately, power steering resumed and I was able to control the car without an accident. This happened again on the same day while turning into a driveway. I promptly returned the car to our GMC service department where a power steering fluid leak was discovered in the power steering gearbox. This is a very serious safety issue. Given your history of the same problem, it is not understood why this is not a safety recall issue.
Driving into a small downtown area to meet some friends and heard a whirling noise coming from under the hood (belt, bearing or power steering). As I slowed down the noise intensified, dissipated as I sped up. Notice the steering was tighter and more difficult to turn the steering wheel at slower speeds. The next day I attempted to "check the fluid" secured under the engine cover but was unable to remove it even with the star bit required. I then google'd auto-steering for Acadia and found numerous issues related to failing power steering units. Took it to the dealer frustrated after finding that this is not an isolated part failure. He stated that the bellow was leaking due to a failure (the power steering is under a lot of pressure I was told) and it needed to be replaced. The dealership completed the repair after keeping the car a day. Seems to me this is a potential ticking time bomb and the part may have been under engineered. I have been a long time gm customer but with all the current press I'm not sure I can support them any longer with my patronage.
The contact owns a 2010 GMC Acadia. The contact stated that the power steering fluid was leaking from the vehicle. The failure occurred on several occasions. The vehicle was taken to the dealer for diagnostic testing, who informed that the failure was normal wear and tear on the vehicle. The manufacturer was not notified of the failure. The approximate failure mileage was 48,000.
While making a hard right turn front tires very difficult to turn very resistant. Front tires felt like being drug across the pavement. Problem became more frequent in both turning directions. Took it to dealership to find out it is a common problem with this vehicle (others complaining of this online). Steering racket cracked and fluid leaking on right internal in bellows. "internal problem with steering gear". I was told this wasn't recalled because it is not a safety issue, basically some one has to die! excuse me, I drive on the country's most dangerous highway, us 50 over echo summit at least once/twice per month. What if this failed? how is a steering problem not a safety issue? I took the SUV in before we were killed!.
