I have experienced two separate incidents of spontaneous windshield cracking on my 2019 Subaru Outback, with no external impact or road debris involved. The first windshield crack occurred, and Subaru replaced it under warranty after inspection showed no signs of impact. The second crack occurred again without any collision or impact. However, Subaru has now refused to cover the second incident, even though it clearly follows the same pattern. There is no visible point of impact. The cracks appear to originate near the bottom edge of the windshield and spread rapidly. I park the vehicle in a safe residential area and have not driven over rough terrain or been involved in any accidents. I have also referenced a known class action lawsuit involving similar spontaneous cracking issues with windshields in Subaru vehicles, including the 2017a“2020 Outback and Legacy models. This suggests a manufacturing or design defect affecting structural integrity. This issue creates a serious visibility and safety hazard for drivers and passengers, especially if the windshield fails further while the vehicle is in motion. Subaruas failure to cover a known defect and repeated issue puts drivers at risk. I am requesting that the NHTSA investigate this recurring defect in Subaru windshields to determine whether a recall or broader corrective action is necessary.
