Safety recall 14s05/the federal safety agency recall 14v‑284 was performed on this vehicle in august 2014. The service performed was a software modification that was described as being able to prevent the vehicle from going into manual steering mode without warning and as a result of a torque senor defect. In january 2016 the power steering assist stopped functioning while driving and moved into manual steering mode. This was in a low traffic urban area at low speed. We were able to get the vehicle off road without incident. The vehicle remains in manual steering mode and there is a "power steering assist fault" warning display on the dash. The ford recall letter indicates the dealer repair would remove this possibility where the vehicle could revert to manual steering mode due to a detected fault. The letter also indicates a chime and wrench light would ensue if a defect/fault were detected to "increase driver awareness". It is not our experience that we had this warning provided. There is no wrench light illuminated and the vehicle was not prevented from moving into manual steering mode. In short, I do not believe that the service procedure in this recall where only software code was modified was sufficient to remove the potential hazards of any defects that may by inherent in the power steering assist system of this vehicle. I contacted the dealership where the software revision was conducted and was told that without a "check engine light" indication, they would probably not be able to read and determine the fault. I indicated the nature of my understanding of the recall on this vehicle to see if a further needed repair of the torque sensor would be allowed under the recall due to these circumstances. I was told the recall was closed. I do not believe the initial repair was sufficient.
