Id start of trying just some black silicone on the tabs. I did this on mine and have yet to have one fall off. I pulled on them after they dried and didnt feel any give either.
I would say its just kids screwing around by stealing the caps but if the car is that vulnerable, I would be concerned that someone might take the car. Maybe try a more secure parking location/system.
