We ran into these same problems with our new Cougar and it was disappointing but the dealership made it more frustrating. We took it back to fix the leaking propane, the light fixture over the bathroom vanity that fell off, the slider on the screen door that wouldn't close, the day/night shade that wouldn't open, and the leaking toilet. They had it for two weeks and then called that it was all fixed. Not one of the items was fixed!
My husband ended up doing all the repairs except the blinds which we are living with. We've since found that the integrated radio/DVD player must be wired wrong because while the radio works the DVD player does not. We haven't fixed that yet either.
If I could find a better service place I would take it in during a time we won't be using it for a couple weeks but there's no way we want to fight with those people again. The service department is so tight it's a pain to even get in and so we start off frustrated.
I'm just thankful that hubby can fix everything and when he gets stuck he has a friend that he can get help from.
