I've now twice had my interior driver side door panel crack. I'm now %100 sure this is occuring due to heating the interior up, that is when it's hitting -20 to -40 and having the far left dash vent defrosting the window so that I can see out of it. So again I've got an appoitment for the dealer to fix this under warrenty. Am I the only one experincing this? This doesn't seem to happen to anyone else I know..
