FUEL/PROPULSION SYSTEM
I was driving down a heavy traffic expressway with a lot of semi traffic and the SUV started puttering. All of a sudden it died, the check engine light came on and I started to slow down quickly. I was in the middle lane of 3 lanes going 70 mph. VERY LUCKILY, I was able to pull to the right and barely made it onto the shoulder. The SUV had $28,972 miles on it. It was more that 100 degrees outside at the time. I called for a tow and had to wait over 2 hours. My car was nearly hit many times during the wait. The whole situation was very dangerous. What if my children were in the car at the time???? The tow truck driver was nearly killed while trying to get it on the truck. He had to call the police to block the lane. He stated that he could not put it in neutral and had to do something else with it to get it up. It was towed to the dealership where I purchased it. They did the diagnostics and said it was a fuel pump module issue. Less than 30,000 miles and this happened. I was planning to take a trip through the mountains, but at this point I do not feel safe at all in this vehicle. THIS SHOULD BE A RECALL IF GMC IS AWARE OF THIS ISSUE!!!!!

The contact owns a 2017 GMC Acadia. The contact stated that the vehicle had to be turned on and off approximately 2 - 3 times to place the gear shifter in park(P), for the transmission to remain in park(P). The message “Shift to Park” would be displayed on the instrument panel. The failure was intermittent at first, but since started occurring more frequently. The dealer was contacted, and it was confirmed that the VIN was not under recall. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 91,587.

UNKNOWN OR OTHER
When I park and then turn the car off the car fails to recognize that the gear shifter is in the park position. As a result, the car doesn’t fully shut down, leaving the engine running or the electronics active. This drains the battery. I have seen this issue is recalled for other 2019 Acadias but don’t under why it is not recalled in mine. I’m afraid I’ll be out and about and unable to turn my car off resulting in a dead battery and being stranded.

POWER TRAIN
The transmission has all the symptoms of a broken wave plate and/or torque convertor as reported in the first generation T75 transmission service bulletin. This started occurring at 120K. I know the service bulletin was for the 2007-2009 models but the 2012 had the same exact transmission and waveplate. The car feels like it's going to shudder out and die on the highway.

SERVICE BRAKES
Purchase vehicle on August 13, 2025 with 27 miles on it. Drove home from dealership. Started the car on Friday morning and all of these warning lights appeared - Electronic Stability Control, Brake Assist Service, Brake light indicator, ABS indicator, traction control indicator, collision warning indicator. Car only had 69 miles at the time. Took vehicle to dealership on August 18, 2025. After diagnostics were performed, it was determined that the Master Brake Cylinder is the issue. The part is on back order and there is no estimated time of when the part will be received and installed. Dealership Rep told me that it was safe to drive the vehicle to the dealership. Service Technician then explained to me that I should not be driving the vehicle.

SERVICE BRAKES, SEAT BELTS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving under normal conditions, the vehicle experienced a sudden, violent deceleration. The emergency braking and collision avoidance systems activated spontaneously, as if the vehicle had struck or was about to strike an object. There was no obstacle, impact, or external threat present. This uncommanded braking caused significant physical stress and injury to the occupants. Critically, multiple safety systems failed during the event: The seat belts did not lock, failing to restrain the occupants; The airbags did not deploy, despite the severity of the deceleration; no warning indicators or diagnostic alerts were present before or after the incident. These failures directly contributed to physical injuries, including TBI (concussion, spinal trauma, etc.) which required emergency medical treatment and ongoing care.

When I turn the ignition off it sends me a message that I must shift to park. The car is in park at that time that I get the message. I restart the car and move the shift to reverse or drive and move the car and place in park and that may correct the problem or I may have to do this once, twice even three times before it corrects. The warning bell will continue to ring and the radio continues to play until I can get the situation corrected.

While 2 hours from home driving down the interstate with a full vehicle, the vehicle alarmed and the screen notified "No Oil Pressure, Turn Car Off Now". I pulled over immediately and we had to sit on the edge of the interstate for 45 minutes - a safety hazard for us and the surrounding traffic. The vehicle was towed to the nearest GM dealer, where they assessed the vehicle and advised that this is a known issue for 2024 and 2025 GMC Acadias and Traverses. The vehicle failed to move oil and the engine was seized - a significant safety hazard. After a month, GM has informed us that zero replacement engines are available in the world and there is no timeline for replacement or repair and the vehicle is unusable.

SERVICE BRAKES
I purchased the vehicle, and twelve days later while operating the vehicle I experienced full braking power failure. My foot was to the floor board while trying to get the car to slow down. Up until the point of brake failure, there were no warning lights or "symptoms" that would alert me as to an impending problem. My young child was also in the car so that was extremely scary also. During this time, the "service brake assist" light and ABS light came on. I was able to slow the car down enough, restart the car, and the brakes seemed to work, however all of the related braking lights were on my dash. It was brought to the dealer the next day. The dealer has noted that its the master cylinder that needs to be replaced. However, they replaced it, and the new master cylinder has also failed, so they'll need to try and replace it again. I'm concerned this issue could cause severe accidents in the future if it continues to not be addressed.
