I'm been having lots of problems with the sunrider pins coming loose while driving; then you notice it when you go to close it, b/c the roof shifts backwards about 1/2 inch and won't close. ...PITA. I've taken it to the dealer about 3 times; they've tried some adjustments and also a new roof. I think the design is nice, but if the roof doesn't exactly fit just so, those pins are going to pop. Instead of just closing the sunrider in a few seconds (the way it was designed to do), you end up having to pull off the back and side panels from their bottom tracks, then lift the whole top/middle roof bar up...that moves the frame forward, then you can pop those pins back in the hole. Bad news. I'm taking mine back to the dealer AGAIN. They did fix & adjust the roof well the 2nd time, but then the back window was very tight and eventually the zipper tore. They had to replace the roof and now we're back to square one. The dealer and I are still trying to figure out a solution. Jeep will probably need to design a better pin system that holds better. I love the sunrider option, but until they re-design the pins, it's a PITA.
