This had happened a year ago. I was driving and my anti collision brake just started to make a beeping noise and was telling me to call a toyota dealer. And before that the anti collision brake would go off when there was nothing in front of me. A few months later my cruise control and lane assist also stopped working. I took it in for a diagnostic and they couldn't tell me the real problem and that it would be 1500 to actually know what the issue is. I have never been in an accident in this car and its annoying that I bought it because of the safety features that I now cant use.
On numerous occasions, while driving in a straight line with our adaptive cruise control on, our 2022 Toyota 4Runner will automatically actuate the vehicle's brakes when approaching a slower or stationary vehicle that is either to the left or right, but not directly in front of our vehicle. This sudden speed reduction has almost caused any following vehicles to almost collide with the back of our 4Runner. It has happened to us at speeds between 30 MPH and 65 MPH. When it happens, one has to quickly tap the brakes to deactivate the adaptive cruise control then get on the accelerator pedal to avoid a collision with any following vehicle. We have taken our 4Runner into two separate Toyota dealerships on three separate occasions to have this problem diagnosed and repaired. The first dealership told us repeatedly that there is no issue. The second dealership pulled data from our vehicle and made an adjustment to the 4Runner's forward camera system. Unfortunately, the day after this adjustment was made our 4Runner irrationally applied the brakes when we were driving 35 MPH on a straight road with no other vehicle in front of us. The problem is not fixed. We are now waiting for a response from Toyota Corporate.
