2016 Mercedes-Benz E350 Visibility (wipers, defrost, mirrors) Problems

“My car's windshield at first started to leak. I took the car to the dealer and was informed that leaky windshields are not covered by the warranty. I took no further action as we were still in a COVID restricted environment and the need for the car was low. As my company started to return to the office I have begun using the car more and have now observed that windshield adhesion to the frame has now deteriorated. The car has approximately 41K miles at which I would not expect the windshield to be unglued. …”

“We have been getting water in the front passenger compartment below the door area, after rain. We took it to our mechanic, who determined that the windshield integrity has been compromised along the top area in front of the passenger dash. Apparently the seal has separated, allowing water to enter the vehicle. Our mechanic stated that the safety of the vehicle has been compromised and the windshield needs to be removed and re-glued.

“Recently (April 2024) we've noticed water drops forming on the inside of the vehicle along the top of the front windshield after a rain. Pushing outward along the top inside of the windshield glass indicates some movement of the glass. This applies all along the top inside of the windshield and not just one spot or area.

We have not yet contacted a dealer; however we have conducted online research that strongly suggests that the windshield urethane adhesive seal is failing. …”

“The contact owns a 2016 Mercedes-Benz E350. The contact stated that water was leaking inside the vehicle through the seal around the windshield. The contact stated that upon manually pushing the windshield, the windshield was movable. Additionally, the contact stated that there was a windy sound coming through the windshield while driving. The vehicle was taken to Dunaway Glass Repair Company, where the windshield was being replaced. The vehicle was being repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not under recall. …”

“The contact owns a 2016 Mercedes-Benz E350. The contact stated that water was leaking from the front driver’s side windshield. The contact also stated that several months later, she became aware that the front passenger’s side windshield was leaking. An undisclosed dealer was notified of the failure and the contact was provided an estimate for the repair, but no further assistance was provided. The vehicle was then taken to a collision center where it was diagnosed that the windshield bonding had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. …”
