Forward Collision Avoidance Related Problems of the 2016 Toyota RAV4

Warnings problem

While changing the lane towards right, suddenly my vehicle over accelerated and was about to crash the vehicle ahead of me and quickly I decided to maneuver towards the right shoulder lane and within few seconds and speedy semi-truck passed from the left and saved our lives of 4 people in the car in the busy highway approaching the o'hare chicago airport. Safety: had I not taken towards right to avoid crash on anther vehicle, the high speed truck from the back would have hit us within a few seconds of my alertness. Yes, during Feb. 2019, due to excess acceleration, this car crashed towards thick ice and snow while driving through a street, and damaged front bumper. (my wife was seated at passenger side) called the dealer and took the vehicle to them(wilde Toyota-west allis), they knew the seriousness, serviced it in their workshop for over a week by changing timing belt, re-programming etc. . Etc. And returned back my car and said now it should work, it is okay as it should be. Yes, my vehicle was inspected twice by insurance company, Toyota officials for airbag inspection, workshop mechanics, due to major road accidents (for not my fault) in oct. 2019 and Jan. 2020 and repaired at another auto body service center in milwaukee(andrew Toyota) and in madison(ballbody-a division of Smart motors). There was no warning signs in the vehicle as the car runs very well on both highway and city roads.
