Soon after I had my infotainment issues diagnosed and new part ordered, the lane keep assist function just quit working. I tried different roads with solid lines, lanes with lines and buttons, turning the function on and off, cleaned the windshield, but the lane keep assist is still inoperative. I get the lane departure warning, but that does not steer the vehicle back towards center of lane. I took it to the same dealership, because the other dealerships service schedules were all taken. The dealer tech wrote that he took the vehicle out on the freeway and the lane keep assist function works properly. He drove it 4 miles. I have driven the car a few hundred miles and it never worked for me. I think the dealer tech pencil whipped this issue just to get rid of it. I figure, if I paid for the feature, might as well have it working as advertised. I will have to wait until I get the infotainment unit installed (I hope that happens soon) before I bring the lane keep assist issue to the dealership again.
