This is ongoing from the purchase of the car. 1) Infotainment computer screen daytime illumination is so dark as to be a major safety issue as it causes too much time looking away from the road to operate the system. If you wear sunglasses you cannot see the screen at all. The dealer says nothing can be done to improve the problem. 2) Right rear tail light stopped working after 500 miles. Replace...

The vehicle experiences a transmission/drivetrain defect involving delayed gear engagement, hesitation, and apparent slipping. When accelerating from a complete stop (especially onto an incline) the engine RPM increases but the vehicle fails to accelerate as expected. The vehicle jerks and shakes violently and is unable to gain speed. This issue is intermittent but highly repeatable and occurs al...

Automatic brake engaged unnecessarily/ unexpectedly while driving forward at a low speed. There was no reason for the brake to engage. There were no objects or people infont of us. This has happened twice in less than a month. Both times we were in a forward motion. It could have been a serious situation if the car behind us had been any closer when we suddenly breaked for no reason.

Warning message appeared stating "service brake assist" and "service ESC". Took vehicle to dealer, they found faulty Master Cylinder. Multiple parts involved, some on back order, could take weeks to a month or more for repair. Vehicle is less than 1 year in service with approx. 6k miles.

I bought this vehicle in August 2025 and October was the first incident that this occurred. What happened was I was driving to pick up my husband and all the warning lights on my car dash started going off and then it died. After we got it started again we took it to the nearest GM dealership and after we parked, we could not get it to shut off then when we started driving again, it died in their ...

OnStar/Telematics Module cuts out, rending GPS and OnStar functions useless

New vehicle. At 935 miles on odometer, displayed “Service Power Steering” “No Assist Soon” message on dash. Contacted OnStar and was advised of potential loss of power steering & advised to take car to dealership. Car spent 10 days in service to have a new steering gear installed at GMC dealership.

Approximately 2 months after purchase, the sunroof spontaneously shattered/exploded while driving on the interstate. We had it fixed and about 3 months after that, the same exact thing happened.

The antenna fin cover came off while driving down the road. I had been a possession of the car less than six weeks. I’ve contacted the dealership- it’s covered under warranty, but the part is backordered because it’s such an issue.

I accidentally ran out of gas and my car died directly underneath a railroad crossing arm. I had been stopped to allow an Amtrak train to go by and my car died when I started to move forward after it passed. Thankfully I wasn't on the tracks, but I was close to them. I immediately got out of my car and the woman behind me said she would help push me out of the way of the crossing arm. I went to pu...

I was driving on a two-lane road when unexpectedly my front moonroof spontaneously shattered sending glass down on top of me, the console area, and the passenger and rear seating areas of my 2025 GMC Acadia. It happened without warning and no external factors. It was a pleasant sunny November day. The moonroof was not open at the time. Fortunately no one else was in the vehicle with me at the time...

I purchased this 2025 GMC Acadia on 3/29/2025. About a week into owning it, the navigation stopped working. OnStar was able to reset my system. Then, about a month later, the vehicle locked my keys in the cabin without my knowledge. OnStar was able to unlock my vehicle remotely. Then, on 10/23/2025, I noticed my navigation was not showing my true location. I tried the Google Assistant, and it wasn...

Brakes have failed now three separate times. The brake pedal becomes firm and the car will not stop or slow at all. I am pregnant and also had my toddler in the car with me. No warning symbols on the dash. Taken to dealership after several weeks of communication saying this was a safety issue and received a loaner vehicle. However, they have said if THEY cannot reproduce the issue, we will just ge...

While driving vehicle, multiple warning codes appeared including: service traction control, ABS, service brake system and others. More importantly, the power brakes failed and a code was thrown to press hard on brakes to stop vehicle.

I have the little feature that will brake for me if it thinks ima get in a wreck. However it’s glitchy!! I can be the only vehicle on road in BOTH directions, cruise set at 60 when out of nowhere the car slams on the breaks. We go down to like 52 then like nothing ever happened we are back to 60. This has happened several times. I have brought the car into my dealership tomorrow have the softw...

We had complete brake system failure while driving the car on the highway. The brakes went all the way to the floor when applied and we came inches going into fast moving oncoming traffic before the vehicle stopped. I had to push the break with both feet with all the strength I had to get the brakes to respond at all. The brake assist failure warning light came on and another warning light came on...

Bought new 2025 GMC Acadia in March of same year. At ~4500 miles I started getting Brake Assist, Forward Collision and Electronic Stability Control warning messages on dash. Upon researching, this is an increasingly common issue with this vehicle that can render the brakes unusable. I no longer feel safe in the vehicle and want it refunded. Car is now in the shop. Taken in on 9/11. Problem has bee...
