2021 Toyota Venza Brakes Problems

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.

2021 Toyota Venza while being driven while merging onto the highway, the vehicle lost all braking power causing my wife to almost cash into the car in front of her. The vehicle was moving between 50 to 55 miles per hour. Once the vehicle was pulled over, the dash was displaying these error messages: Pre-Collision System Malfunction; Braking Power Low/Visit your Dealer; Check Engine; and Secondary Collision Brake System Malfunction. This caused my wife to be stranded on the side of the highway. The vehicle has 24,811 miles on it. The vehicle had to be towed to the Toyota dealership. This is the second time this happened. The first time this happened was about 20 months ago when I had just bought the vehicle new and put about 400 miles on it. The first time the dealership said they could not find anything wrong with it.

After Traction Control recall firmware update was completed, my vehicle now turns on the parking break randomly when coming to a stop while still in drive. The vehicle says time for maitenance with aprox 5,500 miles before service required. Remote services no longer connecting. The firmware update to correct traction control not turning on automatically at vehicle startup has caused other electrical features to fail/malfunction.

The contact's mother owns a 2021 Toyota Venza. The contact stated that while she was driving in traffic and slowing down to 10 MPH with her foot on the brake pedal, the vehicle unintendedly accelerated with a jolt. The contact stated no warning light was illuminated. The unintended acceleration had occurred on several occasions. The contact had taken the vehicle to a local dealer who diagnosed the vehicle and stated that the failure was caused by driver error. The dealer stated that the vehicle information showed that both the brake pedal and accelerator pedal had been depressed simultaneously. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 15,000.

Pulling into a parking spot (under 5 mpg), brakes did not engage. Car drove up onto the sidewalk. Had to put car into reverse to avoid hitting the building. While in reverse, brakes would not engage as well had to turn off the vehicle to stop it after it hit the curb 20ft behind the vehicle. Had vehicle towed to the dealership. They could see where the brakes were engaged 3x, but could not replicate the issue. Although there was snow, ground was not icy or slippery.

Sometimes when I'm driving the Toyota Venza 2021 downhill and press the brakes they freeze and sound weird without control to stop the car. I think is very dangerous. I reported two times in the dealership but nothing happened.
