2011 GMC Acadia: loss of power steering

Filed Aug 2, 2022 · Steering · NJ

Power steering rack & high pressure power steering line. If this fails while you're driving on a highway you will lose power steering causing a serious accident. Also the timing cover is leaking. Both of these expensive repairs seems to be an issue with all gmc acadia SUV's yet the federal safety agency has not investigated or required the manufacturer to do a recall and cover the costs of repair. Costs for both repairs is $5000.00 !!!

Steering binds up and becomes very hard to turn on low RPM or sitting stationary. It feels as if no power steering at all. Have been told by dealership that it is a huge safety issue that gm has failed to recall.

At slow speeds my steering gets very hard as if I have no power steering at all. Very difficult to parallel park. Loud whining sound as I turn the steering wheel. Numerous times when driving on either highway or city street..changing lanes has been difficult and manual steering was needed.

While driving 70 MPH, I was just about to pass a semi when the engine quit, as if I turned off the key, no power steering...nothing. I notice the "traction control" light come on for a second. I pulled to the side of the road. I attempted to restart and the "check engine" light would just flash yet the engine was not turning over. The vehicle was towed to gmc dealer and preliminary reports (incomplete) was it was computer/electrical related. I also noticed the rear lift gate would not open (although this has happened once before two years ago and gmc dealer found "fretting at the lgcm terminals." possibility related, my wife told me only the passenger door window would roll down a few days before but only happened one time. She said she turned off the car and restarted a few minutes later all windows rolled down fine...just another electrical issue with this vehicle. This vehicle also has been having radio issues for years. 1/2 of the radio screen randomly disappears (left). Tapping it sometimes helps and sometimes is flickers wildly on and off. Gmc dealer told us the radio needs replacing...like that's going to happen.

Power steering went out and almost hit another vehicle. Works going down a 2 lane highway over 35 MPH, but stops working as you turn into parking lots, road, etc at lower speeds. Steering is extremely difficult and have noticed many acadia owners are having this issue. Car is a 2011 denali acadia with 103,000 miles.

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!!

2011 gmc acadia, #14329b special coverage adjustment-loss of power steering assist. Coverage good for period of 10 years or 150,000 miles. Acadia started having power steering problem in jan 2017. 2/1/2017 service acadia at the dealer's from 2/1/2017 until 2/8/2017 to replace steering pump. Drove the car from the dealer, noticed it was scary, bouncing right away. Took it back right away. The advisor told me that since the car had been left on the lift the struts on the shocks had expanded. Mechanic drove the acadia and said it was safe to drive. Drove home and other people said it was not normal. Took the acadia back on 2/21/2017. On 2/22/2017 the advisor called and said the car needed new struts for $648.53. The car had only 31, 180 miles. The dealer said it was wear and tear. As a 77 year old retired school teacher, I drive carefully, prudently. Have the old struts. Does this make sense? The dealer should have performed this 'special coverage adjustment to ensure complete safe vehicle operation from the beginning'. Due to dealer incompetence bamboozled into paying for strut repairs. These struts were operating just fine before the pump repair was completed. The car is better. Still does ride as well as before. The car was unsafe. Have 2 invoices, plus special coverage bulletin, plus old struts.

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.
