During the last few months I have noticed a problem with my 2009 GMC Acadia. The problem occurs with the power steering failing when I am trying to steer or turn. It is as if the power steering stops working completely and I am forced to use manual steering which can be extremely difficult and is a serious safety issue.

* transmission was slipping and revving up between gears. Delayed response and clunking sound when it is in reverse. "check engine light" also came on. Barely drove the car to the dealership for repairs. Dealership service advisor scheduled a transmission rebuild. After doing internet search, I saw countless complaints in blogs, sns, etc. There are so many people having this transmission problem. Not acceptable. GMC has powertrain warranty 5 year /100K miles. My warranty expires in four months and GM should provide extended powertrain warranty beyond 5 years based unreliable transmission design/quality. * power steering problem. Power steering is making moaning under low speed driving (in the parking lot, driving around subdivision, etc.). noise is coming from the inside steering column area. Also steering is very tight and hard. Complained to dealership multiple times. Dealership replaced the seal twice, but the problem is still there. Dealership told me that GM does not have a fix for this problem.

2009 GMC Acadia slt1 - 67,000 miles currently. Power steering failing at lower speeds. When purchasing the vehicle used with only 25,000M+- approx. 2 years ago, I questioned the dealership about the whining noise coming from the steering components and was told that this is normal for all acaidias and not a concern. Now the steering is failing at low speed turns. GMC service dept recommending: Steering gear housing $42.14 - 2 bolts $11 - 2 - bolts $7.59 - 6 - P/S fluid $23.10 and flush and bleed system, labor to replace steering gear housing $640.50 power steering pump $155.69 realign after steering gear repair $69.95 labor for pump $315 injectors and coils failing. In Dec 2011, I had to replace coils #2 & #3. I just replaced #6 injector on July 17, 2013 (= $685) and on July 24, 2013 (one week later) check engine light reappeared. GMC service dept recommending: 4 - ignition coils $373.30, 6 - spark plugs $42.25, labor for coils, and plugs $241.50............................................................ total parts $655.07 total labor $1197 tax $54.04 align $69.95 total: $1976.06 offering 40% customer portion pay $790.42 why is there no recall on defective steering components & coils/injectors? in the later 2012 models GM did change the power steering & fluid, so GM is aware that there is a problem with the design. The fuel delivery system is also defective and faulty coils/injectors could and have caused fires. GMC Acadia, Buick enclave & Chevrolet traverse vehicles up to early 2012 models share these above mentioned components are plagued by these two problems along with transmission (wave plate) problems. GM needs to take full responsibility for defective components and not offer discounted repairs.

My 2009 GMC Acadia started to lock up while steering/turning. I took to dealership and was told I needed to replace my rack. They quoted me $1500! I could not afford this, so they told me it's drivable but will eventually get worse. I cannot park easy in parking lots, I can't make easy turns and it's terrifying when I take my kids in the car. I took it other places - some said it's the rack and others it's the pump. So far I had to replace coils every month, my engine had to be remodeled after a rod snapped off into it and now this! please recall this!!!!!!!!! it's a safety issue and way too costly!

My Acadia has some problems with the power steering being "stiff" - or hard to turn in tight spots. (I.e., parking or close turns). I took it to my repairman today and asked him to check it out. He says that he has seen issues with other vehicles, including the Acadia and the enclave - this same issue. He started taking it apart and called me and said the entire power steering system, pump, rack N pinion steering, etc. Have to be replaced. He said he has had to do this in several other vehicles like this. He said that there were already metal shavings showing up. He told me that parts and labor would be around $1,100 to get this taken care of. He said it will just gradually get worse - it shouldn't go out all together all at once, but it would get worse. I have seen 25+ other complaints on this same problem with the same vehicles. When is GM going to do something about this. I have done regular maintenance on this vehicle all along. It has approx. 80,000 miles on it right now. Has been doing this for about a year - not bad - but he is right - getting a little worse all the time.

Vehicle is hard to turn at low speeds, particularly when parking. Seems as though power steering is not working. Took to dealer and was told that power steering pump went out and that steering gear/rack should also be replaced for $1800+. this is ridiculous on a vehicle that was purchased new and serviced every 3000, primarily at the dealership from which it was purchased. Given the other 23 complaints that have been filed for the same issue, it appears to be a common defect and I am extremely concerned about the safety of the vehicle that my wife drives every day with our 2 young children.

The contact owns a 2009 GMC Acadia. The contact stated while driving approximately 5 mph the steering wheel became difficult to maneuver. The vehicle was taken to the dealer for diagnostic testing. The technician stated the power steering pump assembly and the water pump shaft seal had to be replaced. The manufacturer was made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 50,000.

The vehicle's steering stops working at low speeds while trying to park or back out of a parking place. The power steering fails and you must turn the vehicle manually. The issue continues to get worse the longer you wait to get it fixed.

- Mustang, OK, USA

Steering is difficult at low speeds. While driving at low speeds the steering wheel seems to almost lock up and needs considerable force to be turned. The problem is consistently happening every time the Acadia is driven. This problem makes it extremely difficult to maneuver in parking lots and at any intersection. This problem has been going on for a little while and seems only to be getting worse.

Was driving our 2009 GMC Acadia and as I was slowing and turning the car became very hard to steer, if I was applying the brake I could barely turn the steering wheel. I then asked my father to test it out and even he could barely turn it when applying the brakes and was tight to steer in general. I am 500 mikes from home, but not sure it is safe to drive back home. Will call dealer but from all the other complaints it sounds like the power steering pump is or has gone out. This is very unsafe and although I was cautious while driving, it is definitely a safety hazard!!!!

I bought this car in Feb 2012 and from the first time I drove it the steering was very tight and makes a clunking nose in the the front end. Took the car in to the dealer and the power steering pump was changed and this fixed the steering when it was hard to turn. Now it's May 2013 and the clunk is still there and was told its the power steering gear and its about 950 dollars to fix. This is crazy there is only about 83,000 miles on my car. I am ready to let the bank have it.

Bought used 2009 Acadia in 2011 with 55000 miles and nothing but headache 1) 60K miles: Liftgate came crashing down my wife's back while getting the groceries. They should have some safety measures to stop the gate from crashing. 2) 70K miles: Truck wont start in drive way. Towed truck to dealer and they changed fuel pump. 3) 70K miles: Engine misfire code. Replaced one coil. 4) 76K miles: Coolant always low. Dealer changed water pump. 5) 76K miles: Truck hesitate and feel a misfire between 45 and 55 mph. Took truck to dealer and they quoted me over $3300 to replace all coils, spark plugs, steering wheel column and steering rack busing. 6) since we bought the car we cant even drive it with the windows down or the roof open. The truck shakes roughly with both roof and windows open.

On multiple occasions, the power steering has failed when turning the wheel of the vehicle. This specific instance, as I was trying to cross on coming traffic on a major roadway (posted speed limit 45 mph) to get into a common turn lane to merge with traffic, the steering went out as I barely made it into the common turn lane leaving me with concerns about the safety of driving my vehicle. I have concerns that the steering should be failing so quickly after 3 plus years of the life of the vehicle (bought brand new).

I have been having trouble with the power steering in my 2009 Acadia. It looses power for a few seconds almost every time I make a turn now. It is extremely scary if I am in busy traffic. I took it to the dealership and they said that I need to have the whole power steering parts replaced. $1700!!... which is not covered under warranty. I have a friend who is a mechanic and he said that there are more than one component for the power steering and that the dealership wants to replace it all because it is easier than actually figuring out which part is really causing the problem and just replacing that part. This is very frustrating and it is ridiculous that I can't trust the dealership to take care of the problem correctly. We have been researching and finding out that many 2009 Acadia owners are having this same issue. Obviously GMC needs to cover the costs of issues like these that are happening to not just 1 owner but several!!

Driving on sr at approx. 65mph when check engine light comes on and "engine power reduced" is displayed. Car slows dramatically and eventually comes to a stop. Power steering is also lost concurrently. After swerving into opposite lane, I managed to get car off to the side of road. Car was towed to dealership (courtesy GM roadside assistance). Fuel pressure sensor was replaced after finding the sensor intermittently shorting and causing the low pressure condition. The power steering assembly was also leaking. The steering gear was replaced and flushed. Exactly one week later while driving on the same sr at approx. 55mph, the check engine light came on and "engine power reduced" is displayed. Car slows dramatically and comes to a stop. However, this time I was able to steer car off the side of the road with no problem. Heavy smoke was also coming from the exhaust and the car smelled unusual on the interior. After waiting 3 hours for a tow (GM roadside assistance), the car was towed to the dealership. Two fuel injectors were found leaking (# 1 and 3) and were replaced. Fuel injectors 2, 4, 5, and 6 were rebuilt. This same vehicle had two fuel injectors (#3 and 5) replaced in August 2011 when this same chain of events occurred (previously reported). I am concerned as to why fuel injectors in this vehicle continue to fail causing the engine to flood with fuel. The safety concern is the vehicle will decelerate and stop with no warning which could cause a fatality if I were on a interstate with little to no shoulder.

When trying to steer the vehicle below 5 mph's (engine below 1200 RPM), the steering wheel will lock up and is very hard to steer. My wife had this happen to her the first when she was pulling into our driveway (thankfully it did not happen in the city). She told me about it, so I then took it to town shopping. It took a while before it happened to me, but finally it did when I was making a tight right hand turn into a menards parking lot. I started the turn and notice instantly that I had no steering. I almost hit another car because I was not able to steer sharp enough or fast enough for the right hand turn. After that, I got in the parking lot and did a little testing. I figured out that the steering was locked, and if the engine was revved over 1200 engine RPM, the steering would come back slightly. After several tries, it did come back. Don't know if I can trust it to work all the time"?" it appears the problem is worse after the car has been run for a while. With cold temps it works until the steering system warms., then problem is random. Scary!!! feels like there is a flow control valve maybe that is in pump, and when it sticks open, the steering is lost at idle speeds. Not a good deal...

I was driving slow and when I went to turn the steering was extremely tight. I had told the dealership where I bought it from, from the date of purchase that something was wrong. Finally took it in on 10/19/2012 and was told it was the powersteering pump. It's over $400 to get fixed and I don't have it right now.

I had just picked up my car from having the A/C compressor and condensor replaced and I was doing a U turn into a gas station when the power steering went out. I had to manually turn the wheel. With my two children in the back I almost went into a ditch. I immediately called the dealership and took it in for them to look at. They told me that the power steering gear assembly was leaking and needed to be replaced. They found that when the ves valve was commanded shut, the valve would not re-open. The rack was also leaking on the left side. They replaced the gear assembly, set toe and flushed the system. This is a serious safety concern and should be looked into for a recall.

I was in the middle of a turn when vehicle got very hard to control as I was finishing my turn power steering pump started working again and I almost side swiped another vehicle due to the force I had to apply to the steering wheel when pump quit working. Took vehicle to dealer and they said power steering pump was leaking and that there has been multiple accounts of this happening in GMC. They did state it was a mechanical failure in the power steering issue of the vehicle but no recall has been issued as if yet. Any help with this problem would be greatly appreciated. I see this as a very unsafe condition of the vehicle that should be looked at closely upon GMC's behalf.
