Вибух панорамного дахуку автомобіля

Panoramic roof glass sudden failure without external impact. The panoramic sunroof glass burst unexpectedly, a catastrophic structural failure requiring immediate investigation. Such failures can result from manufacturing defects in tempered glass, improper installation stress, thermal stress from temperature extremes, or material degradation. The absence of impact suggests an internal glass defect or stress concentration point that reached critical failure threshold during normal operation or temperature cycling. The roof structure must be examined for installation anomalies, and the glass supplier and manufacturer must investigate whether this represents a design, materials, or quality control issue affecting other units.
