2011 GMC Acadia engine problems

“I had issue with the timing chain an have check engine light is on I have heard other people having problems with there timing chain. It starts hard. I've had it looked at multiple times. I feel like this is a safety concern. It has low miles on it”

“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 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.”

“The contact owns a 2011 GMC Acadia. The contact stated that the steering wheel would shake uncontrollably without warning while driving at various speeds. She also stated that the steering wheel would lock in the middle of turning the steering wheel in either direction without warning. After taking the vehicle to the dealer for routine maintenance, several warning lights appeared on the instrument panel. The contact called that dealer and was informed that the vehicle would reset itself upon restart; however, the failure persisted. A few days later, the Push to Start button failed to operate after multiple attempts and the key was used to start the vehicle. The contact had the vehicle towed back to the dealer and she was informed that the purge valve was defective and needed to be replaced. The manufacturer informed her that there were no recalls on the vehicle and referred her to NHTSA for assistance. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 130,000.”
