The rear windshield shattered spontaneously without any external impact while the vehicle was parked. Mercedes-Benz USA advised bringing the vehicle to the dealership for evaluation of a possible manufacturing defect, but the dealer replaced the glass and charged for repair. This raises a concern for potential safety defect or glass stress failure in EQB models.Owner report · Visibility/Wiper · Oct 2025
