2025 GMC Acadia

crash · towed

We filled a report on 04/04/2026 with NHTSA at 12:16 pm but can't find a copy of the whole report. My husband John Chandler was driving our 2025 GMC Avadia Elevation. He was backing out of a parking place when he noticed it wouldn't stop while putting his foot on the break. He was able to put it into drive and it lundged forward and wouldn't stop. He kept pushing with both feet on the break and wouldn't stop. I tried pushing the start button to stop but because his feet were on the break it would restart so then pushed the park button and it stopped as we hit the building. The air bags did not depoy so not going that fast. I pushed the button for 911 and they came on to assist and call …

Since delivery, my 2025 GMC Acadia AT4 has had severe wind noise from the driver's side window at highway speeds. The noise sounds like fingernails on a chalkboard and at times as though the window may shatter. I have taken it to the dealership 4 times with no resolution. I provided video clearly capturing the noise and was still told they could not hear it. I have confirmed the dealer road tests the vehicle in morning traffic at low speeds — where the noise cannot occur. It only happens at highway speeds. Their "cannot duplicate" finding is the result of inadequate testing, not the absence of a defect. After sitting for approximately 7 days, condensation builds up inside the cabin, …

Our onstar module has stopped working since last November after a software update and now issues are starting to cascade causing many other electrical issues to the point that I expect the car to leave my wife and 15 month old daughter stranded. Ours and many other vehicles are having this issue and when any question is asked to gm no response is given or we’re just told to keep waiting.

The contact owns a 2025 GMC Acadia. The contact stated that while driving uphill at an undisclosed speed, the vehicle hesitated, jerked, and stalled. The vehicle was taken to the dealer, where a computer reprogramming was performed; however, the failure persisted. Additionally, the contact stated that while driving 65 MPH and merging into the left lane, the automatic emergency braking system erroneously engaged and the vehicle hard-braked, nearly causing a rear-end crash. The contact immediately depressed the accelerator pedal, and the vehicle accelerated as intended. The contact stated that the failure was intermittent and had occurred approximately six times. The vehicle was taken to the …

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 …

Telematic Modular Control is not working properly and part is on backorder. Dealership and GMC have refused to put into writing that my vehicle is safe to drive; however, they are refusing rental vehicle while awaiting arrival of part. Several of my safety features are not working correctly, my left turn signal went out randomly and my auto breaking has activated when there has been nothing near my vehicle.

The master cylinder failed under 10,000 miles. I was at 5000 miles. I am reading a lot of people have had issues with the master cylinder in the 2024 early 2025 models. Luckily I was in the driveway barely moving, but man if i were on a highway and it happened it could've been fatal!
