Factory LED running lights

Has anyone had any problems with the factory installed LED running lights on an Elkmont 24?
My combined Break, Turn, Running lights have several LEDs either out or filckering. I removed one of the lamps and it is a single unit with 18 LEDs in each unit (4 units in total). And the LEDs that are out are not the same ones used in each function.

There is no individual wiring to check. There are 3 sets of wires to each Lamp unit.

Anybody have any ideas?
TIA
