“On August 26, 2026, at approximately 5:30 PM, while driving home from work at about 55 MPH, the factory panoramic sunroof glass of my brand-new 2026 Kia K4 spontaneously shattered and catastrophically exploded without any external impact. The sudden, deafening blast sounded like a gunshot or like another vehicle had crashed into me, though I felt no physical impact. This intense noise created an extreme safety hazard as I swerved due to a panic reaction, and could have lost control of the vehicle, or caused a multi-car collision during rush hour traffic. …”
