An official CAA Japan notice concerns Passenger cars (Mercedes-Benz S400d 4MATIC, S500 4MATIC) - Repair. Frame (front wall) defect. Defective component: Frame (front wall). Nature and cause of the structure, equipment or performance deemed noncompliant with standards: The rainwater drainage design at the front wall is inadequate, so water may enter the passenger compartment when a large volume of rainwater or similar water flows through it.

In the worst case, the PRE-SAFE system may be impaired, creating a risk of occupant injury in a collision. Published 2023-06-22.
What to do now
Recall notification number: 外-3633. Corrective measures: Add sealing to all vehicles. Also inspect beneath the floor and, if water has entered, replace affected components with new ones.
