| Description of the problem | Vehicle's front windshield spontaneously cracked overnight while vehicle as parked in a locked private garage. Crack originates at top of windshield frame where body torques the glass and continues through advanced driver assistance systems, ending up in driver's line-of-sight. No visible point of impact on damaged area of glass. Driver assistance and safety systems are affected by the stress crack, rendering them non-functional. Dealer investigated and determined that stress crack was due to a defect in manufacturing and installation of the glass, not due to any impact or road debris. However, manufacturer denied coverage under new vehicle warranty (4yr./50,000 mi), stating that glass defects are only covered for 1 yr/12,000 mi. |
