Service bulletin SSM 51666

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2010-2012 Fusion/Milan and 2011-2012 MKZ vehicles equipped with a 2.5L or 3.0L engine and electronic power assist steering (EPAS), a remanufactured replacement steering gear (MU2Z-3V504-ARM) is available which is significantly less expensive than a new replacement gear. When conducting repairs that are customer pay, offer the customer a remanufactured gear when possible. This would include vehicles not included in field service action (FSA) 15N01 (built on or before 7-Sep-2010) or vehicles included in FSA 15N01 that have exceeded the 10 year/150,000 mile terms of the program.
