Orange Landshark,
I had this happen to me twice in the 3 1/2 months I've had the car. Same exact problem. If you have the turn signal on, it is on, but when you turn the signal off, it fades away again, Also if the the song info changed it would come on then fade again.
There have been a few posts from different people with this problem. Seems to be only 2013 cars with MYLink. (I assume yours is a 2013).
Just some info, Mine was built Feb 28 2013 and I have navigation. Maybe there is a common factor between the cars that are having the problem.
I haven't been back to the dealer yet since I only have 1500 miles, but I will mention it when I go.
Also I have the problem where sporadically the song info does not show on the HUD, (which a few people on here have had it happen too.) and the fan speed stays at 0 when it is clearly on. Sounds like a software glitch to me.
Here are a couple of other threads on this
