Re: 2006 Focus 3 door...power steering pump
You'd have to contact a dealer to know for sure. If you're within' the mileage and year (time) of the warranty coverage then you might luck out. However, I believe only directly related engine and transmission problems will fall under the powertrain warranty. The PS pump will probably fall under the comprehensive warranty.
On the bright side it shouldn't be too much to replace as the engine is of a transverse design (versus inline - crankshaft points toward the rear wheels).
