Anyone lose a center cap?
 

Has anyone had issues with lost center caps on the 18" chrome-clad wheels? We haven't had our Aspen but 5 days, and 1 is missing. It was under the wifey's care, so who knows what happened? She doesn't recall bumping/hitting anything. There's no other damage to the wheel. I was able to pry one off with 1 finger quite easily. Seems like this could be an on-going issue? We do have our share of potholes from the very rough winter.

Update: just got back from dealer. At least they are only $15. I should buy a couple -- before they quit making them. I was expecting to spend a lot more.

Edit: Dealer ordered wrong one :(. Correct list price is $37. They gave it to me for $32.
