The lane keep assist does not work basically , it can't detect the lines , due to the recall I can't charge my car which I paid much more than regular Ford Fusion. To be able to use the electric miles and save on gas , also the 3g modem stopped working and Ford has no fix for that , took it to different dealers and they say even if I replace the old modem with a new 4g, (paying out of my own pocket !!) most likely the app and remote connection will not work .
