Not a typical trait IMO. Leave it at the dealer overnight so that they have it when it is cold. If they can't find anything, try another dealer.

Suggest you don't start the DIY fixes suggested above until you have exhausted all dealer channels, especially considering you have two more years of warranty left.

Good luck.
