FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM, POWER TRAIN
Vehicle has experienced multiple electrical and mechanical failures at unusually low mileage. Purchased at 32,000 miles. At approximately 50,000 miles, the factory radio/infotainment system failed completely. Electrical systems were observed remaining active after the vehicle was powered off, suggesting an underlying electrical fault. At approximately 60,000 miles, the power steering rack and fuel pump both required full replacement and were confirmed and replaced by an authorized dealership. No warning lights appeared prior to these failures — components failed without any prior indication. At approximately 100,000 miles, the transmission began failing and exhibits the known torque converter shudder issue widely reported on this vehicle platform. The shudder was present prior to full transmission failure symptoms appearing. The pattern of premature failures across multiple unrelated systems — electrical, steering, fuel delivery, and transmission — suggests a broader manufacturing defect.

On Sunday June 7, 2026 my husband drove our 2014 GMC Acadia to work. We both work at MSY - Louis Armstrong New Orleans International Airport for United Airlines. After he parked in the employee garage that is located in at the old terminal and got on the employee shuttle, the passenger tail light sparked a fire. Airport operations responded with the fire department that is stationed at the airport.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
Today, June 11, 2026, my wife and 9 month old baby were on their way home from running errands in town when the vehicle started to violently shake, becoming frightened my wife tried to apply pressure to the brakes. When she pushed down on the brake pedal nothing happened and the pedal hit the floor. Our brand new 2025 GMC Acadia AT4 had just suffered catastrophic brake failure. So she pulled off onto the side of the road in hopes the uneven terrain would slow her down just enough to put it into park. Luckily enough it did. If it would have been 10 seconds later she would have been on a one way bridge where the speed limit is 60mph with no brakes. Four days prior to today on June 07, 2026 I sent a message to the individual that I bought the car from at the GMC dealership and told him that we had warning lights come up on the dash. He had me try and reset the screen but nothing happened. I asked when we could get it into a shop so it could be looked at he said that he would have someone reach out and schedule a time. I proceeded to ask if we were ok to drive the vehicle until then.To which he responded "If the vehicle isn't giving you issues mechanically, you should be good". Fast forward to today June 11, 2026 my wife is driving and has catastrophic brake failure. The vehicle was then towed by roadside assistance to the GMC dealership.

SERVICE BRAKES
I was driving and all of a sudden my break pedal was inoperable. It was stiff and unable to be used. Luckily I was only going 40 MPH. I pulled into a parking lot and my car started shaking and apparently the metal parts from the vacuum pump blew into my engine, which completely wrecked my engine. I nearly could have died and now my 2021 car is completely destroyed.

POWER TRAIN
When I shift my 2019 GMC Acadia into park, the warning message reads shift to park and there is a ding warning that plays for several mins. This has been going on for over a year. I took it to the dealership and they said they could repair it for $1000 dollars but the solenoid was only guaranteed for 30 days. There is no possible way a dealership can expect a person to pay $1000 dollars a month to keep their family and transportation safe.
