Same here , Michigan ..temp in the 30's ..Parked in garage overnight and in the morning had 3 cracks running up from the bottom of the windshield towards the middle ..That's right , 3 separate cracks .. No evidence of any damage . I called Tesla service and they have to see it to evaluate if warranteed .. I'll be definately upset if I have to use insurance (I have $500 deductible )
Mine cracked too. Windshield was covered in ice and snow, so I turned on the defroster, and it cracked. I have an appointment this Friday at the SC to replace it. My estimate is $1538.30(I am in MD). Insurance will cover most of it. Hoping they might call it warranty, but I doubt it. Live and learn I guess.
