NHTSA complaint #11459645

Owner complaint summary

I was driving on a divided 4 lane road that offers a wide right side shoulder at around 43 MPH. I was traveling in the right lane. The lane markings are fresh and visible. It was late afternoon and sun was shining. The road surface was dry. There were no vehicles immediately in front of or along the side of mine. I had not activated the lane keeping assist or automatic cruise control features. Only the hazard mitigation/automatic braking and road departure mitigation features were operational. The car suddenly attempted to swerve left, away from the center of the lane being utilized. The automatic braking system also activated. I was able to simply "drive through" the malfunction without incident. This was the first instance I have noted of this kind. Due to the fact that it was late afternoon, there were shadows from overhead power line being cast onto the lane being driven. I have owned previous cars that sometimes attempted to track said shadow when the lane keeping assist is activated. That was not the scenario yesterday as LKAS was not selected. It was as though the sensors detected a pending pedestrian strike or other collision.
