Vehicle vibrates above 45mph. Took it to dealership and they did not fix the issue. Lane departure warning had to be disabled as it is mistaken for an actual lane departure. Vehicle posses a risk to operator and other drivers on the roadway. Toyota corporate notified but disregarded claim as dealership advised they were unable to replicate.
The lane tracing assist (lta) fails to properly deactivate when a trailer is equipped. The owners manual specifically states this should occur, the dash indicates that lta is off but the indicator remains and the system provides steering inputs. When towing a trailer any abrupt movements can induce oversteer or trailer sway leading to loss of control, the lta may perform abrupt movements. I have notified but received no response, so far no accident has occurred. The warning and indicator lamps are not in sync and don't align with the true system status. Details are from when I first noticed this system issue. I'm providing snippets from the manual showing the expected behavior, and the indicators. I also have included a screenshot of a video I made that shows the trailer detection, warning that lta is off and the lta indicator remaining on.
