What 280 owners told NHTSA about the 2011 GMC Acadia

The relay for the fan at the top of the fuse/relay box on the right side when facing the front of the vehicle. (under the hood) Gets hot and blows the relay and melts the spot where the relay prongs plug in. Causing the need for a new fuse box and circuit problems within the fuse box connectors. The fans, specifically the a/c fan does not kick on when turning on the a/c and the low speed fan does not kick on at all until the secondary temp fan kicks on after the temperature raises past the normal operating range. Which an overheating engine is bad for all parts of the engine which can and sooner or later will lead to a catastrophic failure putting the operator and other motorists life's at risk.This time it created a small fire that was extinguished only because the fuse box cover was off and I was looking at it as it happened, putting the cover back on extinguished the fire. This is the third time it has happened with the exact same problem. You tube is full of videos with the exact same problem.

We purchased the vehicle on August 20, 2025. At which time we paid over $4,800 for the vehicle. I will be trying to submit all files pertaining to the vehicle. We are both disabled and on the fixed income from ssi. However, a week after purchasing the vehicle all issues began to rise up. There was no transmission fluid, the oil need changed, catalytic converter showed up on AutoZone print out, wheels to make a sound when turning, brakes needs fixed, electrical seems to have an issue. The reason I am submitting this is in prayer asking for any remedy with this situation through the recalls, bulletins, and whatever else maybe available for the vehicle. I thank you for your time, effort, and consideration in this matter.

My air bag light keeps coming on saying to service it. I saw the recalled issues before with the other Acadias and was thinking maybe my year model would need to be looked into as well. I haven't ever had a wreck for them to come out but the light comes on frequently.

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.

DRLs melted into the housing, seems like this is possibly caused by cowls that are not properly sealed allowing moisture into headlight assembly. This is obviously a fire hazard and will be a costly repair. I am not sure if vehicle insurance covers this but I doubt it.

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.

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.

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.
