Sudden changes in temperature, such as going from a hot environment to a cold one, can create stress on the glass and cause it to shatter. Additionally, manufacturing defects or flaws in the glass can weaken its structure and make it more susceptible to breaking. Finally, impact from objects like rocks or debris can also cause a rear window to burst. Regular maintenance and careful handling can help reduce the risk of a rear window bursting. **
