Power steering stopped working completely.... was taking a turn and the steering became stiff and shook a little and went back to normal. Parked the car. started the car 2 hours later and steering completely stiff... no power steering. a quick google search of this common issue will tell you : Ford owners forum groups with the same issue, complain that Ford apparently only did reprogramming and did not replace the actual part causing the issue, when checking the codes, it did not show the failure yet, so they reprogrammed the unit to check the box Ford completed the safety recall. Recall 14V284000: Loss Of Power Steering Assist the federal safety agency Campaign ID Number: 14V284000 "STEERING:ELECTRIC POWER ASSIST SYSTEM" (5/28/2014) Summary: Ford Motor Company (Ford) is recalling certain model year 2008-2011 Ford Escape and Mercury Mariner vehicles manufactured August 18, 2006, through September 11, 2010. The affected vehicles have a steering torque sensor that may not be able to properly detect driver steering input. As a result, the system could remove the Electric Power Steering (EPS) assist. Consequence: If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash. Remedy: Ford will notify owners, and dealers will update the software for the power steering control module (PSCM) and the instrument cluster module, free of charge. If a vehicle shows a history of a loss of the torque sensor signal or fault codes relating to the PSCM when the vehicle is brought in for the recall remedy, the affected components will be replaced, free of charge. The recall began on July 18, 2014. Owners may contact Ford customer service at 1‑800‑392‑3673. Ford’s number for this recall is 14S05.

I have been intermittently losing power steering. The code is B1342. After researching, it looks like Ford is aware of this problem but is unwilling to fix the issue. This fix must be done at a dealership since it is a software issue and going to cost $2,000. Obviously losing power steering when going at fast speeds is incredibly dangerous for myself and others. There is no check engine light that comes on when the issue arises.
Electronic Power Steering System, which was part of a previous recall, and was allegedly fixed, but continues to experience the same loss of power steering. This is a continual problem, meaning that it is not a one time incident. Yes, the vehicle is available for inspection at any time. When the power steering goes out while driving, the steering wheel jerks to one side, and feels like a lock-up. The vehicle is still drivable, but can be dangerous in a situation where attempting to avoid an obstacle, could result in an inability to do so, because the maneuvers are being executed for a vehicle with power steering, so when it goes out, those same corrections will not successfully avoid a collision. The dealership is aware of the problem. They did a system check and insist that the steering column needs to be replaced, and that it has nothing to do with the previous recall, but it is exactly the same problem involved with the recall, therefore I do not believe they are differing issues. I believe the initial recall repair was unsuccessful, or the wrong fix. There were three or four options for fixing the issue. There are no warning lights that come on prior to the power steering going out, but a click can be heard however, at the exact moment when the mechanism for the power steering goes out. The same click can be heard when the vehicle is started and the power steering does come on. It usually comes on when it is cold outside. It will then go out once the car gets warm. I bought the car in January of 2000, and I did not experience the issue for a few months. When it did start happening, it was only once in a while - maybe every few months. The problem started happening more frequently with time, with the current status being that the power steering is predominantly not working.
