On 4/13/25 while driving my car on the highway, along with my 2 young children, I began to hear what initally sounded like a "flapping" noise. I rolled the windows down and after a minute or 2 the sound got lounder.

I was driving home on a residential street at approximately 30 MPH. I heard a loud pop or bang sound coming from the top middle area of my windshield. I checked for any windshield damage, observed none. I thought the whole noise strange as nothing had hit my car or windshield. A couple days later I noticed that the glass panel between the windshield and sunroof, was completely shattered, with a horizontal crack running across the panel. I also noticed that the framing between the panel and windshield was not right. It sort of was "popped" outward. There was no warning regarding this failure.
