2022 MAZDA CX-5 Forward Collision Avoidance Automatic Emergency Braking Problems

Was driving down a road at around 40 MPH and a vehicle ran the light and took a turn in front of me. I applied brakes but car didn't try to apply them harder from the start and no warnings ever came up. Wasn't able to avoid collision and airbags deployed (only steering wheel airbag)

I was driving in slow moving traffic with vehicles ahead and behind. The vehicle ahead of me slowed, so I applied brakes and began to slow as well. While I was on the brakes slowing at a normal rate with plenty of distance to the vehicle ahead, my vehicle unexpectedly activated automatic emergency braking. It abruptly applied full brakes and came to a complete stop, even though traffic ahead was still rolling. There was zero chance of collision, with ample following distance, minimal speed differential, and brakes already applied. The audible alert triggered at the same time as the emergency braking, providing no advance warning. The vehicle following me was unable to stop in time and caused a rear-end collision with my vehicle. My vehicle had moderate damage, and the following vehicle had more significant damage with airbag deployment. Collision speed was approximately 5-10mph. There were no injuries.
