Same thing happened to mine only the trim fell off while washing it in the driveway. Only 1 of 3 screws holding it on other two were not screwed into anything. I used 3m 4200 marine sealant. Expensive sealant but it's adhesive strength is superior to just about everything else, except 3M 5200 which is a forever fix and can not be removed should you wish to do so in the future. There is a solvent made specifically to remove it, but not worth the effort.
