You may want to check the top piece of molding that fits above your windshield to make sure it is secure.

I was driving about 70mph with my top down yesterday and the molding went sailing over the top of the car. I felt some wind buffeting before the molding came loose, but as I couldn't physically see the molding I had no idea it was coming loose. The wind was blowing pretty hard, so I attributed the buffeting to that.

I stopped by my local dealer this morning and they ordered the part. The new molding will be in tomorrow and the dealer will install when I get the car back to them. BTW, the fix is covered by warranty and there will be no charge.

I wonder how many moldings have come loose like mine did?
