Typical lane departure system symptoms owners report

Owners report the lane departure warning failing to activate during a lane change, in one case leading to a rear-end crash.
A failing thermo control valve or engine coolant bypass valve (P26A3 code) triggers the check engine light and simultaneously disables EyeSight, lane keep, and collision warning systems.
Multiple owners describe a cluster of warnings appearing together: check engine light, RAB off, EyeSight off, and lane departure disabled, often after starting the car in cold weather.
One owner reported the car actively trying to change lanes on its own, forcing them to fight the steering wheel to stay in lane.
Some owners note the disabled safety features stayed off during highway driving, reducing confidence in collision avoidance while EyeSight was down.
