2022 Honda Odyssey forward collision avoidance problems

While approaching an intersection, a 4 door sedan in front of me rapidly applied their brakes to stop for a yellow light. I did not see they had stopped in time, so I rear ended them. The impact was so severe, the engine from my 2022 Odyssey was pushed into the firewall and most likely is totaled. If the Collision Mitigation Braking System (CMBS) initiated, it did not occur before I slammed on my brakes. The airbags also did not deploy. The car is undriveable.

The contact owns a 2022 Honda Odyssey. The contact stated while driving at 50-65 MPH, the collision mitigation braking system was applied and the vehicle stopped abruptly, causing her children to sustain whiplash. The message "brake" was displayed on the instrument panel. The vehicle was taken to the dealer where it was diagnosed that no issues were found. However, the failure had reoccurred several times while there were no other vehicles or objects around the vehicle.
