NHTSA Complaint #11714684 — 2025 VOLKSWAGEN ID.4

I turned on the defroster for the front windshield for the first time on this new vehicle. I had it on for a few minutes to defrost ice from the windshield. Immediately after turning it off, I heard a loud cracking noise. The bottom of the windshield cracked violently at the bottom near the heating element, and some of the glass also heated up so much or sparked that it melted some elements of the car near there. The large cracks are spreading and are obscuring my vision while driving. I am also afraid to turn back on the defroster, despite needing it in the snow this week, fearing that the windshield will crack further or melt/catch fire again. I've read online that this is happening to others with the higher trims that include the heated windshield. The sudden cracks are appearing in the same place in others' cars after they use the defroster. There is now a class-action lawsuit against Volkswagen for this very issue in Canada. The dealer says that there must have been an existing chip in the windshield and that I am responsible, but that was absolutely not the case. And even so, the car shouldn't be melting or catching fire regardless!
