Lose Power Steering problems of the 2010 Buick Enclave

I have a 2010 Buick Enclave with 142,000 miles. I purchased it used at about 70,000 miles. Overall, have been happy with the car but a few months ago I ran into a scary situation that I did not anticipate. I nearly drove into the side of another car when making a left turn from a stoplight with two lanes turning left (I was in the left-most lane and there was another car on my immediate right). My power steering quit on the turn. That night when I got home I checked the fluid and it was right in the middle of band and showed no signs of visibile degradation. I also searched online about this issue and found it is a very common problem with 2010 Buick Enclaves. And from what I have read it is not clear to the dealerships if this problem is a rack&pinion issue or pump or what. Some have been denying there is a generic problem at all. Others have confessed there is a generic design flaw in the system. I don't know if anyone has been killed due to this generic problem but I am certain there must have been some accidents! I warned my wife about the problem and have asked her to not even drive the car unless absolutely necessary. Gm needs to recall and fix this problem. My trial and error testing shows the problem occurs whether turning right or left. It does not happen every time at low speed turns - I would guess 50-60% of the time. No issues when tracking straight ahead. Again - a real safety hazard particularly if turning in front of oncoming traffic and it were to quit and it delays your turn time. Same if turning to merge into oncoming traffic- loss of steering could delay your ability to merge and result in a rear end collision. I am 61 yo and have owned a number of cars over the years and have never lost power steering before. Unless this is remedied properly by gm I am not sure I would buy another Buick or gm product.

Lost power steering at low speed.

My 2010 Buick Enclave, with 60,000 miles lost power steering while I was travelling on the highway. The steering basically locked up, I had great difficulty getting the vehicle off on an exit, so that I could call for help. I had to be towed to a dealer. I was told that the there had been a leak in the rack and pinion assembly leading to pump failure and gear damage, their estimate to fix: $1800. I was also told by the service department at the dealer that the engine motor mounts are loose, the engine physically moves about 6 inches when the accelerator is pushed.

The car has had a whining noise in the steering for a long time. Have been told lots of things about the sound and the reason behind the sound. About 3 months ago while making a u-turn at red light the car's steering lost its power steering momentarily. It become extremely difficult to complete the turn and made for a very difficult situation. Oncoming cars were not as easy to avoid as the steering become almost impossible. At a local auto repair shop after the incident we were told that this was a very common incident with the Buick Enclave. We then called a local gm dealer and their service department, only to be told that there occasionally is air bubbles that happen in power steering systems and that the whining noise is okay. I asked if this was a common problem to be told that this is not common, even though I was told by a auto repair shop that it was a common problem. After dealing with this problem for the last 3 months and putting my small children and wife in the car, I am unable to do this any longer. It is not a safe situation, not even a little bit. My wife nearly wrecks into other cars pretty much anytime she tries to park the car in a store parking lot. After researching the internet, I am finding thousands upon thousands of other people with the same problem. I would like to believe that maybe it was just my car, but I don't think that every Buick Enclave should lose its power steering at 70000 miles. That is not good. Do something please!.
