Sorry to read about windshield damage on your B250e. I noticed the windshield in mine has a slight pink tint which I've not noticed on other vehicles.
I don't have an electrically heated windshield, is that an option?
I'm surprised that an electrically heated windshield is available on an EV, due to the high current draw. My B250e has an electrically heated rear window and there are warning messages in the Owner's Manual about not using it more than necessary, and that it may not activate (or switch off early) if the 12V Battery is not sufficiently charged.
I do need to defrost the inside of the windshield on cold mornings, and doing so sets the blower to high speed. The air never feels warm, not surprising for an EV (ICE vehicles has an abundance of hot water...) On a cold morning my range drops fast, again not surprising for an EV.
Best of luck in getting a replacement and insurance coverage, please post a follow up.
