Hoglou,,I had the same problem with my Dometic LEDs..
New 2014 3050 and within 8 mos those lights warped up like a twisty snake in the track. My RV was parked outside all last year so I'd assume the hot summer days created quite a bit of heat next to that rolled up black awning.
I took it in for warranty replacement, that light fixture is a long plastic channel that slides into the track, and upon sliding the new one in it fillet itself and was ruined. A month or so later back at the shop they installed another one, but a few months later I could see it bulging out of the channel in one spot.
I'll leave it there until it warps or fails again then I'm going with the DIY light strips everyone's talking about.
The Dometic channel plastic strip is a poor design and fails too quickly IMO. Oh, but they replaced that wrinkled awning as well once the service department saw how bad it looked. If anything, I'm just happy that I got my awning all straightened out
