The driver-side front door window developed a crack suddenly while the vehicle was in normal use. There was no known impact, and no object was seen or heard striking the glass. The crack originated near the edge of the window close to the side mirror and spread across the glass. There were no warning messages, alerts, or prior symptoms before the failure. The failure appeared spontaneous. This condition poses a safety concern because the integrity of the side window is compromised. The crack continued to spread, which could reduce occupant protection in the event of a side impact and may lead to sudden shattering. It also has the potential to affect driver visibility. The issue was not inspected by the dealership prior to repair. The dealership advised that they could not perform the repair in-house and directed the repair to a third-party glass facility, where the window was replaced. No definitive impact point was identified prior to replacement. Based on the fracture pattern and lack of impact evidence, the failure appears consistent with a stress-related crack rather than road debris damage. Additionally, there are multiple reports from other owners describing similar cracks occurring in the same location on this vehicle model, suggesting a possible defect trend. The original failed component is no longer available for inspection, as it was replaced during repair.
