Water gets in the seal of the upper rear tail light/cargo light. The water leaks through damaging the headliner and carpet. Also blew my fuse and none of the lights work in it, as well as blowing out the fuse every time I replace it. There is still no updated version or recall for it all you can do is get a new one and hope it lasts a little longer.
