NHTSA Complaint #11693689 — 2025 GMC ACADIA

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 warning lights have ever come on. It’s a brand new 2025 car with only 800 miles on it. We were advised by the dealership who sold us the car to get OnStar to tow the vehicle to our local GMC dealership where we bought the car. When the car was hooked up to the diagnoses machine it said brake system failure. I have not received any invoices or paperwork to send you at this point. All I can upload is a video of the warning lights that were appearing on the dashboard after the incident.
