Loss of power steering while driving
On May 27, 2014, amended June 2, 2014, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to the federal safety agency describing a safety defect that may result in a sudden loss of power steering assist while driving in approximately 746,067 model year (MY) 2008 through 2011 Ford Escape vehicles equipped with electric power assisted steering (the federal safety agency 14V‑284, Ford 14S05). Ford's DIR described the defect condition as a poor signal to noise ratio [SNR] in the torque sensor within the Electric Power Assisted Steering (EPAS) system [which] does not allow the PSCM to determine the driver's steering input. When the system detects this fault condition, it transitions the EPAS system to the fail-safe/manual steering mode.Ford's DIR indicates that loss of power steering assist while driving would require higher steering effort at lower vehicle speeds, which may result in an increased risk of a crash.Ford's remedy instructs dealers to check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTCs) to determine the proper repair procedure. If no DTCs are present, dealers are to update the PSCM and instrument cluster module software. The updated PSCM software changes the torque sensor fault strategy so that the SNR condition does not result in a loss of power steering assist while driving.In addition, audible and visual warnings are provided for torque sensor faults.If DTCs indicating faults in the torque sensor, PSCM or Power Steering Motor (motor) are present in the initial recall inspection, the dealer performs the following repairs: 1) replaces the torque sensor for torque sensor faults (DTC B2278); or 2) replaces the steering column for faults related to the PSCM (DTC B1342) or motor (DTC B2277).Continued in attachment pages

Car has been rock solid reliable up until 3 weeks ago. Driving normally on city streets the car abruptly shut down the hybrid and ice propulsion units. Steering froze up and it was like putting the brakes on it stranded me in the middle of traffic causing delays for other drivers and a dangerous obstruction. The car has no limp mode to allow for safely getting out of traffic. It had to be towed. Ford dealer has had car for 3 weeks and are still uncertain as to what caused the unsafe shutdown.

I have a 14s05 hard steering, power steering control pump no longer works. This causes my brakes to seize up. The diagnostic also indicates codes c1480 r/f, c1478 l/f, c1313b r/f. Indicating. Brake failure. I am driving this car to commute 45 miles each way to work daily. I am very afraid because this car is a hazard. My VIN# does not show that this car is among the group that have a problem but. I do have it. Ford is aware, why should I have to pay for the cover up of their error? It is very difficult to drive, an extreme effort is needed to make any turn, the turn radius has increased I cannot safely turn a corner in the city or on an off ramp. The steering wheel and tires immediately snap back to the forward position
Vehicle was being operated at approx 35 MPH when system horn sounded then steering column locked up, causing near miss accident. Ford refuses to acknowledge any recalls or reassess recalll under nhts campaign 14v284000 for steering where their fix appears to be to reprogram software. Appears that this was a quick fix that didn't solve the problem
The power torque sensor for the power steering was already recalled and had the system updated before I got the car in 2014. The cars steering wheel starts shaking a little then all of a suddle the steering wheel locks up and the power steering stops working, so you can't hardly turn it. I came inches from getting in a wreck. You can update the system but it will only work for about 1 or 2 years.
