Complaint Summary

VISIBILITY/WIPER

Owner Narrative

I own a 2022 Mercedes-Benz E350. The front glass roof panel located directly above the windshield developed a large crack while the vehicle was parked. The crack extends nearly the full length of the panel and includes areas where the glass has separated along the fracture. I am not aware of any collision, road debris, or object striking the vehicle before the damage was discovered. The damaged panel is available for inspection. I am concerned that if this type of failure were to occur while the vehicle is in motion, broken glass could fall into the passenger compartment or be shed onto the roadway, creating a potential safety hazard for the driver, passengers, and other motorists. The vehicle has been inspected by a Mercedes-Benz dealership, and the damage has been documented for repair. To my knowledge, there were no warning messages, alerts, or other symptoms before the crack appeared. The cause of the failure is unknown. I am aware of reports from other Mercedes-Benz owners describing similar cracking of roof glass panels. Based on those reports, I am concerned this may indicate a broader design or manufacturing issue and respectfully request that NHTSA investigate whether this represents a pattern affecting similar vehicles.
