Slight pulse left then pulse right actually moves steering wheel but vehicle stays on track - unless driver is unaware - but drive becomes aware because it's a movement on a smooth road them is alarming - then it's always noticed

- Hebron, IN, USA

The vehicle has been looked over by many mechanical professionals. At slow rates of speed, intermittently the steering will stiffen and lock up making it very scary when driving. We have been told over and over that rack N pinion and pump are fine. After researching, this looks like a typical issue. Is there anything that GM can do for this?

- Springfield, MO, USA

Steering wheel making a whining/rubbing noise. Fluid leaking under the car. Took to the dealer and was found to have tack and pinion is bad spraying out power steering fluid everywhere. Was told that the steering will lose power and become either hard to turn or not turn at all causing danger to ourselves and others. This is a known issue that has not been recalled by GM.

Dec 2018 my Acadia was left at the service department of whitmore Chevrolet in West point va 23181 for a diagnosis. My vehicle ran when I left it there. Over a month later including illegal activity in the service department I get my vehicle back and it is dead. I would start my vehicle and drive away sometime stopping soon or randomly on the road. It's done that several times. I have three children too. I need my vehicle looked at and the possible recalls fixed. I am without transportation and it's unbearable. I am a mother of three wonderful sons and we need our vehicle to run please!!!my review is in the pictures as well

I just got my GMC 4 months ago and after every light and alarm has gone off the leak of power steering fluid has cause me to take to a dealer and I have been given a $2600 bill to replace the rack and pinion and pump. This is not just an issued with my GMC my sister has a 2011 Acadia and had the same problem. This for sure needs to be recalled as there is something wrong with it.

- Burton, MI, USA

Bought a 2009 GMC Acadia in February had it for 2 weeks and was pulling out of a fast food restaurant getting my 3 year old daughter some food as I was pulling out I lost all power steering. I could not get my SUV to turn I barely bumped a car thank goodness it did not do any damage and no one was injured but this is definitely something GM needs to fix!! I am a single mother and can not afford to have this fixed especially after spend 10,900 on purchasing the vehicle.

At low speeds, the power steering intermittently cuts out. The steering wheel almost seems to lock up.

- Milford, MI, USA

Power steering went out when rpms are low. In my incident I was transitioning from one freeway to another making a right turn about 40 mph. I took my foot off the gas to take the turn slowly. As my RPM went down my vehicle would not turn right any more. The wheel got stuck in the last position before I let go of the gas. I had to give it gas to make the vehicle power steering work again. My concern with this is not that the power steering failed but that steering in general was locking. I have driven cars with out power steering and never have to worry my wheel will lock. The dealer says I need a new power steering pump. But again it should not lock my turn. I had to give it gas to get the RPM up and then it would turn. Once of the freeway at the stop light I tried turning the wheel and it would not turn. Once I gave it gas we were fine. I should not have to worry about getting stuck in the middle of the road turning. My research has found many issues with Acadia steering pump. This is a safety issues that could of caused a major accident.

- Alburtis, PA, USA

There is an ongoing and unresolved issue concerning the power steering rack and pump on GM lambda chassis vehicles. The vehicle will intermittently and unpredictably lose power steering assist creating an incredibly dangerous situation. While under warranty the factory quietly supported multiple repairs of the same components- rather than recall this situation GM chose to continue to use their supply of deficient components while they seemed to "wait out" the warranty and thus no longer be liable.

- Old Bethpage, NY, USA

While driving it's like the steering goes out and you can not turn the wheel have almost gotten into several wrecks because of this issue, it does not do it all the time but lately a lot more often the past few weeks, to the point that I'm almost scared to drive it. This is my means of transportation to and from work so I must drive it..

- Ponchatoula, LA, USA

While driving my power steering will go out. I have almost hit several vehicles due to this issue. I think this needs to be addressed asap.

Please fix this issue,

April 26, 2016 - my wife was at a gas station and said the wheels on the GMC were very hard to turn either way. Shortly thereafter, she started to hear a whining noise when she would turn left or right. A day later, the noise was more pronounced so I went out for a test drive. The steering seemed ok and the whining noise didn't seem that bad too me. April 28, 2016 - my wife said the noise was louder so I test drove it again, this time, I experienced a momentary loss of steering power on low speed. One time I overcompensated when it was hard to turn the wheel but avoided having an accident. I performed the owner's manual checks, power steering fluid level was good. I then goggled for more information online about steering issues and how to resolve on GMC 2009 Acadia and then I ran into the GMC service bulletin sb-10056459-3388 online. The bulletin described the intermittent power loss we experienced. The condition is described as follows "vehicles may develop a power steering pump wear condition that can cause an intermittent drop of power steering hydraulic pressure that will cause reduced or loss of steering assist. The vehicle may revert to manual steering which requires greater driver effort, particularly at low vehicle speeds". I called our local GM's service department for an evaluation but have not received a callback yet. I am concerned because I believe, if not resolved, may turn out to be a safety issue for us.

- Albuquerque, New Mexico, NM, USA

I own a 2009 GMC Acadia. While trying to turn my power steering will go out. I have almost hit 3 different vehicles due to this and barely made it in to a parking lot off of a busy street. This is a very dangerous and serious problem that GMC needs to address. I have a daughter that I am worried about letting ride in the car with me due to this.
