We have had to slam our hatch repeatedly to get it to close whenever it was quite cold out. We also get the hesitation too but we have also had ours stall a few times when trying to drive it cold. My DH, a mechanic, says that that is very strange thing to happen on an electronically controlled vehicle. My front passenger door hinges don't seem to like the cold much either because they creak and groan when the door is opened. These things, among others, are on my list for the dealer to look at.
