Automatic Emergency Braking problems of the 2023 Chevrolet Trailblazer

I was in a collision. Traveling a four lane highway during daylight ours with no in-climate weather. The car in front of a line of approximately 4 cars missed their exit and slammed on his breaks to make a right turn from the driving lane. The line of cars in front of me stopped and/or left the roadway to avoid a collision. I was unable to stop in time and had nowhere to go and I rear-ended the car in front of me, which was fully stopped in the lane. According to my dash camera my speed on impact was approximately 45 mph. No front end collision warning alarms went off. No automatic breaking occurred. No airbag deployed. None of the vehicle safety and anti collision measures performed as I had expected. $10,000 worth of damage to my car alone.

I was driving west on i90 near belvidere IL, through a construction zone. All of sudden the vehicle stopped by its self. I had no control except for the steering. Once on the left shoulder of a four lane hwy(one way), another four lanes on the other side. There was a cement barrier blocking from the other side traffic. I smelled like burnt rubber, now I now it was the brakes. I checked under the hood did not see or smell something burning. After a few minutes the SUV was able to move. I was afraid for my life, just waiting on a vehicle to hit me.
