“There is an open recall which has not been addressed in a timely manner. The below has been open since OCT 26, 2023.

“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. …”

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. …”
