2019 Platinum. A month or so ago I had a branch come down and hit the A-pillar on the passenger side. It left a small dent but otherwise you cannot tell, and the dent you really have to look for. Ever since then, lane keeping assist stopped working. It would never register the lines in the road so I wrote it off to a camera issue and I would look into it when I had time. All of a sudden today the LKA would intermittently work while driving down the freeway. Then all the way home it just started working. Very strange. Does anyone know the routing of the cables for the LKA and where the harness plugs are? I will stick forscan on it tomorrow but I guess with it working it won't complain about anything. Anybody have issues with intermittent operation of the lane keeping system?

 

There's a lot of room inside those huge A pillars... a small dent would not harm wiring inside. It's easy enough to check, since the interior trim comes off with 2 screws. I suspect the timing of your lane-keeping malfunction and branch strike is a coincidence and you do have some issue with the camera in the windshield.
