The Critical Safety Issue
Engineering investigations revealed a potentially dangerous defect in the fuel system:

- Overfilling risk: This malfunction causes the rear tank to continuously pump fuel into the front tank

- Driveshaft contact: Expanded tank may rub against the rotating driveshaft
- Fuel leakage: Friction can puncture the tank, creating fire hazards
