Mine never worked, and I never got the autopilot lane. It was bad up front cameras. Took a week to fix, but eventually they replaced them, and it's worked ever since.
I'd call and say you saw people with the issue on the forums, and maybe that'll get your car fixed faster than mine.
I only saw the lane for 10 miles out of the first 400, so if you are constantly seeing the lane, than you might have a slightly different problem than me.
PS. I took it to Burbank as well.
