Bought this 2017 Acadia Denali new - it has every option, including the extra cost option "Continually Variable Dampening System". Within a week after buying the vehicle, drove 800 miles to Houston and immediately experienced continuous body roll. In Houston, took vehicle to Wiesner Buick GMC in Conroe. They kept vehicle overnight, then reported that "everything was normal"..........they claimed they couldn't detect any body roll.

Drove the "wandering/rolling" vehicle back home to St. Louis Metro area. Took it back to selling dealer, who twice kept the car, then arranged to have GMC factory engineers inspect the car. The GMC reps never showed up, but declared the car "normal" after seeing the dealers inspection reports.

Took car in for a front-end alignment and had settings changed to maximum limits of normal alignment settings, and car improved somewhat.........but still had noticeably body roll.

Within 10,000 miles, the roll increased.........again tried alignment......but no improvement.

Contacted GMC corporate about issue, and they declared the car normal...........suspect they "flagged" my VIN, because when I took the car the largest GMC/Buick dealer in southern Illinois, they refused to accept the car in their service area.

Now have 30,000 miles on vehicle and have all service (including warranty work) done by a local Chevrolet dealer.

Really suspect something wrong with the computer that controls the Continually Variable Dampening System, but can't prove it,and no GMC dealer will "touch" the car.

Suggest all stay away from the Continually Variable Dampening System option if you're considering GMC.

I am very unhappy re: my 2017 GMC Acadia. On December 2, 2017, I took it back to the dealership (Beck & Masten GMC) in Houston, Texas, and of course, they did nothing. The service clerk told me that they took my GMC for a test drive and it runs fine and like it should. She's a clerk, so how in the hell does she know how a vehicle should run. I told her that it doesn't run properly, it rocks, and people get from behind me. She continued to say the vehicle runs properly. (If she knows that much, then why in the hell isn't she a service manager?). I boldly looked her in the face and told her I am taking m vehicle elsewhere and I left.

On Friday, April 30, I took my vehicle to Knapp Chevrolet and they balanced it and replaced the front tire on or about April 11. The vehicle ran fine for a day or so, but is not rocking back and forth at slow speeds. This is so frustrating and embarrassing. I will NEVER BUY ANOTHER GMC VEHICLE. My Acadia has a little over 5,000 miles and it runs like CRAP! In a nutshell, it's a piece of junk!!!!
