2016 TOYOTA HIGHLANDER Forward Collision Avoidance Automatic Emergency Braking Problems

On multiple (3-5), but not all, occasions at the same location my pre collision warning and automatic breaking appear to have been triggered as I approached an expansion plate at the edge of a bridge. The pre collision warning sounded, then the brakes were automatically applied. After a few seconds the braking stopped and my car proceeded normally. If a car had been following closely I may have been struck in the rear.

I have had problems with the brakes since I bought the vehicle new in 2016. I have the brakes checked every year and when I had problems but they never found the problem why the brakes do not work. The worse accident was on November 19, 2022 when my wife was using the car. She was in the car alone. She went to brake and the brakes did not engage, she slammed on the brakes 4 times and the car did not even slow down and she rear-ended the car in front of her. The air bags did not engage and she was injured. The brakes do not always work, I have gone through stop signs and red lights but the dealership says there is no problem.

brakes did not work in January 13, 2023 when backing out of driveway. Have had numerous dealership look at it multiple times in last 4 years.
