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.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering steering on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
SOME 2010-2016 EPAS EQUIPPED VEHICLES MAY EXHIBIT STEERING RELATED NOISES. THE WORKSHOP MANUAL (WSM) DIAGNOSTIC PROCEDURES HAVE BEEN UPDATED IN SECTION 211-02. WHEN DIAGNOSING AND REPAIRING EPAS STEERING NOISES USE THE UPDATED PROCEDURES.

The failure pattern owners describe
Owners of 2012 Lincoln MKZ vehicles describe power steering failures that start intermittently and escalate to constant problems. Early symptoms include a "Power Steering Assist Fault" message and stiffened steering wheel that temporarily resolve when the car is shut down and restarted. As the fault progresses, restarts stop working as a remedy, and the steering becomes difficult or impossible to turn—sometimes locked—while driving at city speeds, highway speeds, or even while parked.
Multiple owners report complete steering failure during active driving: one owner's steering seized at 40 mph while turning, forcing the vehicle onto a curb and fracturing rims; another couldn't steer right on a curve and went down an embankment, injuring their knee; a third experienced simultaneous steering and brake control failure after being hit, requiring emergency brake pulls to stop. One owner replaced the rack and pinion module twice within 3.5 years.
An NHTSA recall (15V340000) addresses steering in 2012 Lincoln MKZ models, but multiple owners report their VINs were excluded despite the vehicles being built at the same facility and exhibiting identical failures. Dealers cite out-of-warranty status and quote $1,800–$2,500 for repairs. Owners note parts backlogs exceeding 1,700 units, creating month-long repair delays.

Failure modes owners describe
Power steering assist fault with intermittent loss of assist
Electronic power steering system fails intermittently, triggering 'Power Steering Assist Fault' messages and causing the steering wheel to stiffen or become difficult to turn. Most owners report the fault clears temporarily when the vehicle is turned off and restarted, but failures become more frequent over time—initially occurring every few months to every couple of weeks, eventually occurring on every drive.
When: 29,000 to 224,000 miles; complaints span from 2 months to years after purchase
Symptoms owners cite: Power steering assist fault message displayed on instrument panel; Service AdvanceTrac warning light illuminated; Steering wheel stiffened or became very difficult to turn in both directions or on turns; Audible chime when fault occurs; Manual steering required until power assist returns; Failures intermittent at first, then progressively more frequent
Codes mentioned: 15V340000 (NHTSA Campaign Number for Steering)
Repairs/costs cited: Dealers diagnosed need for power steering gear/rack and pinion replacement; estimated $1,800–$2,500. Owners report part backlogs exceeding 1,700 units. Some owners replaced rack and pinion module twice within 3.5 years. Multiple owners report dealers said their VINs were not included in recall despite same factory build and identical symptoms.
Recalls/TSBs owners mention: NHTSA Campaign 15V340000 issued for 2012 Lincoln MKZ steering system; however, multiple owners report their VINs were excluded from recall despite meeting criteria and receiving no recall notice. Manufacturer referred some owners to NHTSA and refused coverage citing vehicle age (over 10 years) or warranty expiration. One owner noted part has backlog of 1,700+ units.
Complete power steering failure during driving—loss of control hazard
Power steering system fails completely while vehicle is in motion, requiring excessive manual force to steer and resulting in inability to control the vehicle. In several instances, owners could not recover steering control and vehicles crashed into curbs, embankments, or other obstacles. Incidents occurred at speeds ranging from 15 mph in city driving to 60 mph on highways.
When: At varying mileage; incidents reported between 29,000 and 200,000+ miles
Symptoms owners cite: Steering wheel seized or became completely unresponsive; Excessive force required to steer vehicle; Vehicle drifted across lanes or went down embankment; Tires locked during turning maneuver; No steering recovery despite engine restart attempts; Traction control system light illuminated simultaneously; Both power steering and braking control compromised in one incident
Codes mentioned: 15V340000 (NHTSA Campaign Number for Steering)
Repairs/costs cited: One owner had steering wheel seized at 40 mph and damaged rims and tires from driving onto curb; tires were replaced. Another owner needed PCM replacement after vehicle went down embankment. Dealer inspections identified rack and pinion failure in at least one case. Most repairs not completed due to cost and warranty denial.
Recalls/TSBs owners mention: Manufacturer notified in multiple cases; some referred to NHTSA. No manufacturer-initiated fixes offered outside the limited recall campaign 15V340000. Dealers stated VINs not included in recall system despite same factory origin and identical failure mode.
Directional power steering loss—steering failure on turns
Power steering assist cuts out selectively during certain turns (most commonly right turns), requiring driver to steer manually until wheels are straightened, at which point assist returns. This creates inconsistent and hazardous steering behavior.
When: Age and mileage not consistently stated; one complaint at operational stage
Symptoms owners cite: Power steering shuts off on right turns only; Manual steering required mid-turn; Power assist returns when wheels straightened; Inconsistent steering response
Repairs/costs cited: Dealer inspection found no fault; dealership attributed to 'new car design' and declined service.
Recalls/TSBs owners mention: None documented; dealer dismissed complaint as design characteristic.
