i have noticed that Lane Following Assist only is active while on cruise control. And if the OP favours one side of the lane there could be a tendency to pull away. That LFA is a bit disconcerting and a tad dangerous in my opinion. On a well marked road, on cruise one can quite easily leave the driving to "auto" and read a book.Turn off Lane Following Assist! Have the exact same problem--drift to the right. Thought it was an alignment problem, but realized no drift at low speeds, only at highway speeds so not alignment or mechanical. Turning off Lane Following Assist (LFA) solved the problem. Will report it to the dealer next time it is in to see if they admit to the problem and/or have a fix. (Lane Keep Assist works well.)
