ref rear spoiler
Mine has come off twice, once caused by an ice buildup and opening the rear hatch causing the spoiler to break, and the second time by a combination of high winds, (tornado), and a screw coming loose. I was able to super glue the bolt slot into the correct spot and attach the new spoiler. Lucky i quess. Be sure that the tabs that the spoiler attaches to are aligned correctly, they are pretty tricky. If you get ice on the roof, don't open the hatch until you clear it from the lip on top of the hatch.
