NHTSA complaint: 2023 MAZDA CX-9 — FORWARD COLLISION AVOIDANCE: WARNINGS
I was approaching Breezewood, Pa coming south on 70 into town from Hagerstown. Traffic comes to a stop awaiting a light that stops the highway traffic before allowing people to proceed through Breezewood and then continue on 70 out of town. I had plenty of warning as traffic slows first from 55 to 45, then to 35 before the light. As I applied pressure to the brakes the vehicle would not slow down. I released them once and reapplied and it felt as if they were doing nothing to slow me down. There were a lot of cars ahead of me and around me and the car did hold its lane thank goodness, but I ended up colliding with a stopped pickup/trailer (Ram with a car carrier/flatbed trailer). None of the vehicles collision avoidance warnings or safety features seemed to assist in the warning of the impending collision or deployed upon contact. No air bags, beeping of warning light - nothing. The vehicle is only months old - and tires are even newer than the vehicle as I had winter tires on it up until about two weeks before this trip. The weather was gray, it had rained lightly for several hours before - but it was 50 degrees.
