GMC Envoy back window shattered possibly due to heat exposure on GMC Envoy

Some GMC Envoy owners report experiencing issues with back window shattering, particularly due to heat exposure. They note that thermal stress from frequent heat can weaken the glass, making it more prone to cracks and shattering. Additionally, sudden or intense temperature changes may create stress within the glass, leading to potential breakage. Owners also mention that damage to the window frame can reduce the cushioning effect, increasing vulnerability to shattering under heat or pressure. Furthermore, driving vibrations combined with heat transfer from the vehicle frame can damage the edges of the glass, contributing to spontaneous breakage. It is crucial for owners to address a shattered back window promptly to mitigate safety risks and prevent further damage to their vehicle.
