NHTSA Complaint #11691576 — 2024 GMC ACADIA

1. The electrical system and driver-assistance/safety features malfunctioned, including intermittent power loss and dashboard system failures. The vehicle is available for inspection upon request. 2. The malfunction caused the vehicle to lose power to the braking system while driving, which created a risk of collision. Essential safety features such as power steering, brakes, and warning systems were impacted, putting both myself and other drivers at risk. 3. Yes. The issue has been reproduced and documented by the dealership during multiple service visits and reported to GM customer service. However, the safety claim was denied by GM and I have been advised to continue to drive this unsafe vehicle. 4. The vehicle has been inspected by the authorized dealership and GMC technicians. It has not been inspected by police or insurance representatives at this time. 5. Yes. Warning messages appeared on the dashboard, including system errors and power failure alerts. These issues first appeared around 20,000 miles, and have recurred intermittently since then. I have communicated with the dealership where the car was purchased and GM corporate requesting replacement with a safe and reliable vehicle. To date, I have not received a satisfactory resolution. I have researched and found that other 2024–2025 GMC Acadia owners are experiencing the same issue. This vehicle is unsafe to operate until GM identifies and resolves the defect. Losing control of the brakes constitutes a catastrophic safety failure that makes this vehicle unfit for road use. Immediate investigation and corrective action are necessary to prevent potential accidents or injuries.
