The wheel cap fell off of mine within a week or so of delivery.
Dealer replaced it under warranty.
Noticed that clips were not very effective securing cap so glued new one on with weatherstrip cement. No more problems and easily removeable if required in future.
Found original cap a couple of weeks later undamaged by mower so now have spare.
I believe mine disappeared during travel from the dealer in the highway. I never really paid attention but I think the original was gray, the stock one above is black. Maybe it was changed since 2014?
