2021 Toyota Highlander Lane Departure Problems

The lane assist will not stay turned off, even when it is done manually each time I get in the car. The steering pulls me back when I'm trying to change lanes, making it unsafe.

The rear cross traffic avoidance does not detect a person on a bicycle or motorcycle. The safety sense 2.5 + was advertised and demoed to detect even a pedestrian walking behind the vehicle. The system on my vehicle does not work as advertised and after taking my vehicle to the Dealer was informed by the service manager that the system is "intermittent at best". This is not what Toyota advertises. Dealerships apparently have no signal strength detection equipment to verify proper operation of this system. I have reviewed multiple videos of this system in operation and there were no indications of intermittent failures. I have contacted Toyota Customer support and am being ignored.

The contact owns a 2021 Toyota Highlander. The contact stated while driving 60 MPH, the vehicle inadvertently attempted to navigate the steering and lane direction to the opposite direction of where the contact was attempting to steer the vehicle. This caused the contact to manually steer the vehicle into the center lane. There were no warning lights illuminated. The contact took the vehicle to a local dealer who inspected the vehicle but could not diagnose the cause of failure. The dealer informed the contact that the vehicle lane sensor and steering assist sensor were performing as intended. The contact was concerned that the sensor should be adjusted so that the sensor would not have to adjust so easily while the contact was driving. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 5,000.

I consider this a vehicle safety issue. Was on the freeway, center lane of a 3 lane highway. The vehicle to my left began to move into my lane. I had to quickly move to my right, activating my lane departure and steering assist. This caused my vehicle to attempt to move me back into my lane (where the other driver was now trying to occupy!). I was shown how to disable this feature if desired but what I wasn't told by the dealer, is that this feature can no longer be set to default to off. I just finished a lease of a 2018 Toyota Rav4 which also had this feature but once I disabled it, it was disabled unless I re-enabled it. With this new vehicle, when you disable this feature, it's only disabled until you turn off the vehicle. When the vehicle is turned on again, this feature is set back to active. I checked with the dealers service department and they said that this is how this feature will work moving forward, that you can no longer set it to off as the default setting.
