“While operating the 2004 Subaru Legacy lt at a speed of 30 MPH a loud noise was heard from under the hood. Immediately the power steering was lost, causing sever lack of control, the battery trouble light and brake warning light came on in the instrument panel. Luckily no accident or injury occurred. Upon inspection (under the hood), it was noted that one of the two drive belts had been ripped apart and the second belt had been dislodged from it's pulleys , leaving the power steering, alternator, air conditioner etc without drive belts. …”
