The engine light came on. Had a mobile mechanic look at it, he ran a diagnostics, it showed a P0017 code. He advised to get another opinion on how to repair, as he said it may need a new engine. Took it to a local repair shop, was told the same thing. The Acadia runs fine, and only has 116K miles. The problem is that it will not pass the required emission test for annual registration and tag. The cost of a new engine was estimated at about $10K, which is more than the Acadia is worth. Was told that these vehicles have had a history of this same issue.

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 a busy freeway, my car lost power and became very slow at only 20mph. Almost got rear ended, luckily I was able to pull over. Then check engine light came on. My engine failed and had to tow it. Mechanic said faulty timing chains destroyed my engine. Bought a used engine and is costing me over $4,000. I was lucky not to get killed. GM knows there’s a timing chains issues with these engines. People have complained about this costly and dangerous problem. They should recall and pay for the repairs. There was no warning for me until it was too late.

Accordingly, the said vehicle first manifested a dangerous defect issue on July 14, 2021, while traveling out of town. A significant and abrupt reduction of power completely disabled the vehicle while parking in a parking space .Despite several attempts, the vehicle still fail to start. Only to notice the engine light illuminating and flashing repeatedly. At the same time the dashboard indicated a faulty reading of fuel and oil. This is a very serious and frightened situation because I received absolutely no warning before the vehicle shut down. Without reason of doubt, I do believe it is unsafe, extremely dangerous and is potentially a hazardous situation that should be investigated. Fortunately, I was in a parking lot went the problem occurred. Whereas, if the vehicle engine stopped abruptly in the mist of traffic it could have resulted with a different outcome. On July 16th the vehicle was towed to a certified GMC dealership for further inspection. Hours later, I received the service contract and a follow up call from the dealership given that the diagnostic is the Engine Control Module (ECM) and needs to be replaced. Surprisingly, to my dismay I was advised that General Motors no longer make the part and the Service Center is not sure when and if the part will be available. As of today, July 26th, no one has taken the necessary steps to remediate my situation. I have already attempted to resolve this problem by contacting the Manufacturer directly. Yet, no information on when a resolution will be made. I have been a loyal customer for several years and currently seeking answers.

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.

My son was driving down hwy 281 and all of a sudden locks started going up and down like crazy, traction control, stability track, engine light all came on and car would not accelerate. Thank goodness my fianc was with him and they managed to get home safely. The next day all the same things above plus backup camera not working and when it park, the box around p kept flashing on and off. Now car won't accel hardly at all. This is very dangerous when your out on roads. There's needs to be a recall and gmc needs to take care of their customers before someone gets killed! I have seen several posts with the same issues so what is taking gmc so long to fix their problems on vechicles?

My vehicle has 136,000 miles and the timing chain is out, I have had to have the front passenger axle repaired, there is an oil leak. I had the vehicle checked while under warranty because the check engine light would come on, the service department said it was because the gas cap wasn't tightened. Now I have no warranty and the timing chain needs replaced. The first day I drove my vehicle the brake system failed, it was brand new. It had had several recalls.
