Some 2015-2018 Flex, Taurus, Police Interceptor Sedan, and 2016 Navigator vehicles may exhibit a turn signal that does not operate as expected when the steering column multifunction switch is moved to the lane change position, then quickly changed to the opposite direction detent position before the lane change flashes three times. Reprogram the Steering Column Control Module (SCCM) using the appropriate Ford scan tool or equivalent release 110.03 or higher. Make sure you are connected to the internet when entering module programming to obtain the latest updates.

When does it fail?
Of the 19 steering complaints filed for the 2015 Ford Flex, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
Steering accounts for 20% of all owner complaints filed against this vehicle, across 5 categories tracked.
No new NHTSA steering complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
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 report sudden loss of power steering assistance while driving, typically signaled by warning messages ("Steering Assist Loss - Service Now," "Power Steering Assist Fault," "Steering Assist Malfunction," "Steering Service Fault") and sometimes accompanied by chimes or dashboard symbols. The power steering system reverts to manual steering, making the wheel extremely stiff and requiring significantly greater effort to turn—a hazard especially at highway speeds and in traffic. Failures occur across a wide mileage range (52,000 to 183,000 miles), with no clear pattern tied to age or maintenance. Some owners report the issue resolves temporarily after restarting the vehicle; others experience persistent failure. Root causes cited by dealers and owners include motor position sensor faults detected by the power steering control module (PSCM), faulty steering gears, and faulty rack-and-pinion assemblies. Diagnostic code U3000 and related variants are mentioned. One owner noted a failure occurred shortly after a battery cable assembly replacement. Repair costs where stated range from $2,200 to $2,600. Most failures occur during active driving—at speeds from 25 to 70 mph—creating immediate collision risk. Owners emphasize the safety danger of sudden loss of steering control in traffic or on narrow roads.
