2011 GMC ACADIA Complaints

LOOKING INTO A CHECK ENGINE LIGHT I FOUND I HAD A MISFIRE IN A FEW CYLINDERS. LOOKING INTO IT I FOUND OIL IN MY SPARK PLUG TUBES, MY COILS WERE PERFECTLY DRY AND THE TOP OF THE TUBES WERE DRY AS WELL. LOOKING INTO THIS ISSUE I FOUND MULTIPLE TSB FORMS FOR THE ISSUE STATING THERE WAS A MANUFACTURE DEFECT IN THE HEAD. IT SAYS IT EFFECTS ALL VINS FOR ALL YEARS AS THEY USE THE SAME ENGINE.

I was driving on the freeway then my car suddenly started slowing down. I tried changing lane so i can pull over on the side of the freeway but unfortunately i couldn't get to pull over before the car completely stopped on the freeway. I called AAA. They sent a tow truck which came to the freeway to tow my car. My husband came and took me to work. The car was towed to a GMC dealership. I went to the dealership after work. I was told my car has timing chain problem and if not fixed will damage the engine. I went online to read reviews of this car only to see it was a very common problem for this year and model of GMC which if i have ever read those reviews i would not have bought a GMC. This vehicle should be recalled for this issue.

Looses power while driving. Cannot jump the battery it needs to be recharged every time. Power steering stops working while driving( low rpm and when stopped) dangerous for merging or lane changes. Engine shudders when trying to accelerate. TCM/ ECM replaced 2020. Problem still persists. Whining noise upon start of the vehicle. Auto start will not work. traction control light, check engine airbag and

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 NHTSA HAS NOT INVESTIGATED OR REQUIRED THE MANUFACTURER TO DO A RECALL AND COVER THE COSTS OF REPAIR. COSTS FOR BOTH REPAIRS IS $5000.00 !!!

The contact owns a 2011 GMC Acadia. The contact stated upon starting the vehicle, the steering wheel became difficult to turn. There was no warning light illuminated. The contact stated that he used his knowledge of vehicles to depress the accelerator pedal, which raised the RPM and caused the steering wheel to become operative.

Hi, I think the 2011 Acadia Denali should be in the recall along with the Terrain. The reason being that I always get flashed at night and every night as though I have the high lights on which I don’t. That’s every night. Please check into this. With all this road rage going on I worry I might come across one angry person or cause someone to wreck. Please I’m worried. Thank you.

While driving down the road, transmission will shudder and have difficulty maintaining constant speed. This is especially dangerous while merging on to the highway. It is searching for the gear to be in while rpms are fluctuating.

The contact owns a 2011 GMC Acadia. The contact stated that while driving 60 MPH, the subframe underneath the driver’s side felt loose and not properly aligned. The contact merged to the right lane and continued to drive the vehicle. The contact stated that her son and daughter drove the vehicle and noticed the failure as well. The contact stated that the vehicle was taken to a local Pep Boys who replaced all four tires and performed a 4-wheel alignment; however, the failure had been reoccurring and was more noticeable while making turns and driving around curves. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The approximate failure mileage was unknown.

Upon starting our vehicle to leave the breaks were very hard to compress. They did eventually release but made a whooshing noise as though there is someone blowing air from the brake pedal. There is no damage or leaking from the break line or the master cylinder. This could lead to failure of the breaks and it is concerning. This vehicle is available upon request to inspect. This has not currently be confirmed by a dealer or service center, or others that would inspect vechicles. There are no warning laps or messages presenting. 11/23/21 is the first day that this occured.
