Normally I would have told you to turn on your propane detector because when it's off it won't allow gas to feed those two things. However since you have gas except, when slides fully open I would think that there is a kink somewhere. DId it work fine before and all of a sudden stop working? I believe there are gas lines that hang in the storage compartment (in my '08 anyway), could you have something stuffed in there that is catching and kinking a line?
It is a 2014 and under warranty so barring those things I have mentioned let your dealer figure it out and have a relaxing coffee while they scratch their heads
