Automatic Emergency Braking problems of the 2021 Toyota Venza

I was on the highway, no ice on the road, in a construction zone, going about 50mph. The cars in front of me stopped completely, and the light to warn me to "brake" came on the dashboard to engage the brakes, but the emergency braking system failed to engage the brakes and slow down the car. I also pushed on the brakes, but nothing happened, the car did not seem to slow down at all, like I had no brakes. I kept going and crashed into the vehicle in front of me. It's like the brakes did not work and the automatic braking did not work either. There was a complete system brake failure. Also, the air bags did not deploy, which I'm surprised with so much front end damage to my car. The brakes also did this last year, and I collided with a vehicle the same way, but there was ice on the road, so at that time, I attributed it to the icy road. Now since these two accidents are so similar, I am concerned about a defect in the brakes and automatic emergency braking system. I am also worried to own a vehicle with the automatic emergency braking system. I am having the vehicle towed to the dealership to have the brakes looked at.

I was pulling out from a stop sign to cross a four lane intersection. I attempted to pass between two cars, but the emergency brake system activated, presumably because the first car was still in front of me, even though it would have well passed by the time I got there. Because of the emergency braking, I was left stuck across two lanes of traffic with cars coming toward me and no way to get out of the way. This has happened twice in 800 miles on the car. I live on a very busy intersection and it took me a couple of months to get comfortable driving in this congestion. I think the car simply isn't designed for that level of traffic, but the way that it's reacting is terrifying.
