Mercedes-Benz Issues Urgent Recall for 20,000+ S-Class Sedans Over Critical Brake Defect
Understanding the Brake Hose Safety Concern
The German automaker has identified a manufacturing defect in the front brake hoses of certain premium sedans that may lead to:
- Fluid leakage: Compromised hoses can develop leaks in the hydraulic brake system
- Reduced braking performance: Loss of brake fluid increases stopping distances
- Crash risk: Significant degradation of braking capability in affected vehicles
Industry safety experts at MotorVero emphasize that this defect poses particular risks during emergency braking situations or when driving at higher speeds.
