Power steering fluid hose bracket broke, allowing hose to make contact with belt pulley. Driver side of engine compartment. Belt pulley wore-away hose until fluid suddenly escaped while driving, causing a sudden loss of power steering while driving around a curve in heavy traffic. This situation was extremely dangerous, and if the Explorer had been driven at the time by my wife, I have no doubt that she would have lost control of the vehicle and been involved in a potentially life-threatening accident. My hands, wrists, and arms are much stronger than hers. She would have been unable maintain safe control due to the sudden loss of power steering.
Replaced hose. Securely fastened hose to NOT touch pulley in future.
There should be a recall. Who was the genius who designed this?
