When the outside air temps are very cold..anywhere from -10 to -20C the cowling around the front windshield makes a really loud cracking noise. It is so loud you can hear it over the radio. It is a very scary noise and sounds like the windshield is going to break in on you. We have already replaced the back windshield as it just exploded last winter when we started it one day in the cold. We took it into the dealership and of course it wasn't cold enough out and they looked at us like we were crazy. Every winter this happens.
