We have a 2015 179 that we bought brand new in April. The spoiler on the top in the back does not light up at all; all other lights (breaks and turn signals) work just fine.
When we picked up the Pod, and the first couple of times we drove it, my husband was always standing in the back when we did our break/turn signal checks, and he can't remember if it ever lit up or not. We've checked the roof INSIDE the trailer right about where the spoiler is, and haven't seen any warping or signs of water leakage.
Has anyone here had trouble with their spoiler lights? If so, did you attempt to repair on your own or take it to the dealership? We're trying to get an idea of how hard it might be to take off ourselves to look at the wiring (my husband suspects it might just be a case of loose wires or something). If it's too difficult, we'll probably just wait till the fall and add it to the small list of items for our dealer to take a look at.
