Assist problems of the 2020 Toyota Highlander

When I am using the brakes an a medium rate the vehicle will loose its brakes for a second causing a loss of control on the vehicle. This happens randomly and caused us to almost go off a culvert of a driveway once. It has scared us many times to thinking we were going to hit the car in front of us. It makes my wife sick every time it happens. Smart motors and regional techs from Toyota have looked into this issue and determined this to be a “feeling” and not a safety hazard. This is not the case and needs to be fixed before someone gets hurt. Lane keeping assist is unusable. When it is turned on it fights with the driver. It will swerve back in forth in its lane and sometimes so bad it feels like the car would roll if it was not turned off and got worse. Every once in a while it will try to take an exit on the highway by itself. Date of incident in questionnaire is approx to the last time it happened. It has happened too many times to count. Vehicle mileage is when we first started really having issues with the brakes. Lane assist is an always thing.

The lane keeping assist does not work properly on my vehicle. The lane keeping assist does not keep my car in the center of the lane as intended. For instance, it very forcefully makes the car drift to the left and right of the lane and frequently pulls it into the other lane. I have reported this to my local dealership - sparks Toyota in myrtle beach, SC and Toyota corporate. Sparks Toyota service has admitted that there are many customer complaints about this issue. They have stated that there is a software download "fix" in the works, but not yet available. I did not take their word for this and called Toyota corporate. The only "solution" I have been offered is an offer to show me how to turn the feature off. This is totally unacceptable as the is an important safety feature that does not work properly and in fact, creates an unsafe situation while driving. Since my report of the issue, I have been made aware of an owners facebook forum that other owners state they are having the same issue and seems to be a widespread problem.
