2016 GMC ACADIA Complaints

Technician told me the engine "grenaded itself". "Cylinder #4 melted into the side walls of the cylinder wall caused by air to fuel mix ratio controlled by the ECU failure to mix appropriately." My family and I were traveling for Easter and were stranded on the side of the highway. I had a private repair shop (Greenville Auto Clinic LLC) confirm as well as the local dealership Greenville Chevy. The vehicle required an engine replacement. I did contact GMC's Zone Manager out of Atlanta, GA for assistance, he reduced the bill from over $10,000 down to $6098. There was no error messaging, only an engine that would not respond to the accelerator pedal. The engine would try to accelerate, but struggled to the point it would die when I applied too much pressure on the gas pedal.

The cable that attaches the front driver seatbelt to the base of the seat (left side), suddenly broke when simply buckling the belt.

TRANSMISSION BEGAN HESITATING AROUND 1800RPM WITH ONLY 92,000 MILES SHOWING ON THE ODOMETER. IT FEELS LIKE A FLUTTER AS THE TRANSMISSION SHIFTS INTO THE NEXT GEAR. I HAVE HEARD THE 2016 YEAR GROUP HAS HAD TRANSMISSION PROBLEMS. BELIEVE A RECALL IS JUSTIFIED.

Without warning transmission overheated, blew out fluid and caught the front end of the vehicle on fire

The torque converter has been going since before I bought this vehicle. When the RPMs are between one and two, the entire vehicle starts shaking and there is no acceleration. This is a huge safety concern, especially with traffic.

Hello. I got a recall and fixed in July 2021 for Blind Spot Sensors/Modules on my 2016 GMC Acadia SLT. Now 3.5 years later Im having the same issue with these sensors that are located in the rear bumper of the car, they get water damage, corrosion, and then fail. A very poor design. And seems like the recall didn't fixed the issue either. This must to be a common issue for this car, lots of complaints online even after the recall. And the car dealership wont cover it because it was already fixed at that time and my warranty on my car expired not to long ago. They said it would be about $2000 to fix. I feel like this prematurely failed and it was recalled once for the same issue but now failed again is crazy after 3.5 years. This shouldn't be a on going thing especially after a recall. I shouldn't have to pay for this outta my own pocket for a flawed design and would like my repairs for this to be covered again. Please help. Attached is a invoice from July of 2021 recall that was repaired. I only got a verbal estimate from the dealership (text messages) which I do have. saying that it would be a $2000 fix this time. I didn't go through with it because I feel like it should be covered. Attached pictures of sensor/module in rear bumper that is corroded. Lights on both side mirrors will come on and stay on. Won't shut off. Messages on dash saying "Service Side Dectection System". Blind zone setting won't shut off.

The shift to park. It does not want to stay in park. I feel that if it does not stay in park, the vehicle could roll forward or backwards. Yes, it was looked at by an independent service center, and they thought it was on a recall. This is a 2016 GMC Arcadia and the 2017 model and newer have this problem and were on recall. No one else has looked at it. I do not drive the vehicle that often, so it does not have many miles on it. I took it out a few weeks ago and I noticed it.

Odometer Fraud. The contact purchased a 2016 GMC Acadia on February 28, 2026. After purchasing the vehicle, the contact obtained a Carfax report and discovered that there was a mileage discrepancy. The vehicle was a dealer sale. The contact called the dealer and was informed that the vehicle was purchased at an auction. The dealer agreed to refund a portion of the cost of the vehicle. The contact attempted several times to contact the dealer afterwards but was unsuccessful. At the time of purchase, the mileage was 92,400, and at the time of registration, it was discovered that the mileage was 192,000.

I have a recall on this vehicle that GMC has failed to provide me parts/repair and this recall will be 3 years old in June. I have emailed the local dealer, the manager of the local dealer, GM corporate, and no one has followed through. The best I came to getting the repair was that Corporate made sure I had an appointment and dealer had my part, I went to that appt at my local dealer in Jan 2025 (Premiere GMC of Carlsbad, CA) and waited 2 hours with cars ahead of me (even thought I had an appt) only to be told the part was not there, they would order it and get back to me. Happy to [provide proof of emailing local dealer, GM Corporate etc. with no resolution. I cannot sell my vehicle without this repair done. And I continue to drive daily in an unsafe car.

While operating my vehicle, the power steering suddenly failed without adequate warning. The steering became extremely difficult, creating a significant safety hazard for myself, my passengers, and other drivers on the road. A sudden loss of steering assist increases the risk of collision, especially at lower speeds, during turns, or in emergency maneuvers.
