Automatic Emergency Braking problems of the 2022 Chevrolet Trailblazer

On April 13, 2025, around 5:00 pm, while driving, a warning appeared on my dashboard: “forward collision system reduced. ” not knowing the full meaning but understanding it could pose a safety risk, I immediately contacted the dealership the next day. I informed them it was urgent, but no one followed up. Days later, I called again and was told to bring the vehicle in. When I did, I asked about a rental vehicle (previously provided during another incident), but was told no rental would be offered until the car underwent diagnostics, which would take 3–4 business days. I explained I rely on this vehicle for work and couldn’t leave it that long without transportation. I was dismissed without any explanation of the warning. Despite reporting a system warning related to crash prevention, the dealership allowed me to continue driving. No inspection was done, and I received no help understanding the message or resolving the issue. On may 8, 2025, I missed a stop sign and collided with another vehicle. The crash caused major damage and totaled my car. The forward collision system never activated—no alerts, no automatic braking. The vehicle was advertised to include safety features like collision prevention that would warn or stop automatically. This failure contributed to the crash. I was cited for failing to stop and driving without insurance. I believe the system malfunctioned and that the dealership acted negligently by not inspecting the vehicle promptly. The issue has not been confirmed by the dealer because they refused to inspect it. The vehicle may still be available for inspection, and I plan to have the black box (edr) data analyzed. No warning lights appeared before April 13.
