On several occasions, this vehicle break pretty hard for no apparent reason in a red rectangle with a crash symbol came up on the windshield a few times we’ve had people behind us which created dangerous situation and there’s no apparent reasons for this vehicle breaking there was nothing in front of us at times there were vehicles in the other lane, but at other times there were no vehicles around at all I was wondering if this what’s happening with other GMC’s or or any GM product.

What component or system failed or malfunctioned, and is it available for inspection upon request? Horn began sounding unexpectedly and intermittently while driving and parked. How was your safety or the safety of others put at risk? The uncontrollable horn startled surrounding motorists and pedestrians, causing confusion and defensive reactions. While removing the fuse temporarily stopped the noise, it eliminated a critical safety feature. The horn remains inoperable as of 4/6/26. Has the problem been reproduced or confirmed by a dealer or independent service center? GMC Dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? GMC Dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No prior warning. Issue began Jan 31, 2025 (66 days after purchasing the brand new vehicle). Timeline of events: Jan 31, 2026: Horn began sounding unexpectedly and intermittently while driving and parked. Per dealership advice, the horn fuse was removed to allow for safe travel. Feb 5, 2026: First service visit. Service advisor reported a "kinked wire" was found and repaired. Feb 15, 2026: Issue recurred; horn sounded continuously while driving. Fuse was removed again to disable the horn; it has remained inoperable since. Feb 26, 2026: Second service visit. Dealership diagnosed the issue as a faulty steering wheel and placed an order (ETA: 7–10 days). Mar 3, 2026: Follow-up call. Advised the part was under “national control” with an additional 10-day delay. Mar 13, 2026: Dealership notified me that the steering wheel request was denied by GM because the part is restricted and the cause remained unproven. Mar 18–20, 2026: Third service visit (loaner provided). New diagnosis identified an internal failure in the SIR coil. Part was confirmed as backordered.

My wife and child drove the car to the grocery store and parked the car l. When she returned to leave , the car would not start and flashed a warning with key fob not detected and some kind of security light warning. The instrument cluster told her to place the key in left console cup holder to crank the vehicle . This did not work either .I drove the second key fob to her to determine if it was a key fob issue and the 2 nd key did not work as well. Called dealership and service requested the car being towed. Tow truck didn’t feel comfortable with the removing the vehicle as it was sitting due to space in the parking lot. They dispatched a small tow truck , but in the meantime I disconnected the battery cable and waited about 15 min. The car cranked and I immediately drove it to dealership. There was no code shown at the dealership and this was the first time they have had dealt with this issue. The mechanic drove the car the next day and the same situation happened again , except this time the key fob worked after several failed attempts . I feel that this is a safety issue because the car failed to operate and had no manual ability to operate without the electronic system functioning properly and this could have happened anyway and stranded my wife and child . A few months before in an unrelated incident , the power trunk malfunctioned and had to be reprogrammed . It would not operate except manually . Car is currently at dealership still being evaluated .

Vehicle would not run due to a failed fuel pump control module. With a non-running engine, the transmission could NOT be placed into Neutral to be able to movie vehicle out of the road. Needed tow truck to move vehicle. This condition placed many people at risk as the vehicle could not be moved out of the way until a tow truck arrived.

The contact owns a 2023 GMC Acadia. The contact stated that while driving on the highway at an undisclosed speed, the vehicle stalled, and the engine lost automotive power. The vehicle was able to restart. During a second failure, the vehicle lost automotive power and stalled in the middle of the highway, and the vehicle was unable to restart. An alert message was sent by OnStar reporting a transmission or engine failure and advised that the vehicle needed immediate service.

I was driving on the highway, and the sunroof was closed and the cloth screen that would allow or not allow sun to come through was also closed. Then out of nowhere there was this explosion sound which scared me so much, I almost wrecked the car and at first, I thought maybe someone shot at my car and shot one of my windows but as I got to the side of the road I realized that none of my windows in the car had been shot and that it was the sunroof and I noticed that cause pieces of glass came into the car from the sides of the cloth barrier. This happened so fast and was so loud that it almost caused me to hit the other car in the lane to the left of me on the highway. Thank goodness I was able to react fast and pull the car back into my lane. I contacted the dealership and they indicated that they had not heard about this before and that I would need to talk with the service department but that it is closed now and not something that would typically fall under warranty. I did check online and see that this is a known issue for this vehicle so I don't understand why it would not be fixed cause it is going to hurt someone at some point. I am trying to get someone to look at it to get it fixed. There was no warning of anything. It just exploded all of the sudden and glass was all over.

Infotainment system freezing, screen shaking, touch screen not working, disconnecting from android auto, unable to connect to phone.

My 2023 GMC Acadia consistently makes a sound at lower speeds when it is changing gears. For example, accelerating or accelerating for stoplights. The sound is kind of a ka clunk. The technician can find nothing and does hear the sound when we go for a test ride. I am worried that the sound indicates a transmission problem. The VIN search does not show a recall for my vehicle.

From the day that I’ve gotten this vehicle it has been burning oil and water like crazy. There is no reason I should be putting a quart of oil every couple weeks

My 2023 GMC Acadia experienced a complete electrical system failure while driving on an interstate highway. During the incident, the vehicle lost all electrical power, including hazard lights and steering assistance, and could not be shifted into neutral. The vehicle became immobile in active traffic and required police-ordered towing due to safety risk. This incident was the second alternator failure within six months. The second failure involved a GM-installed replacement alternator that failed prematurely. Both incidents required towing, and the second created a significant roadway safety hazard.

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.

I've had the engine stall before coming to a complete stop on several occasions. It also has been shifting hard and has had a delayed shift. The other day all of the lights to to screen and speedometer completely went out while driving then randomly came back on. That's the only speedometer I have is the digital screen.
