   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!

   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.

   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 that said SERVICE ESC. I have this on video. This was the first time the…

    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 been confirmed by dealer.

    I purchased the car on [XXX]. Drove the car about 8000 miles and then all of a sudden the dash lights all lit up for the brakes, ABS, traction control. I pulled the car over and turned it off. When I restarted my car, the lights continued to stay on and it told me to service immediately. I called my dealer and they could not get me in within 2 weeks so I took it to another local GMC dealer who could get it in to look at it that week. I took it in on July 9th, and then…
