Lost power steering. Light is on for the electric power steering assist. Happened while driving.

Our 2009 Mercury Mariner suddenly lost its power steering this past weekend. The vehicle was brought back to the dealer in 2014 due to a power steering recall. The vehicle received a software update which was supposed to override the loss of steering and provide an indicator light to show the system had failed. There was no such warning and the sudden changeover to manual steering is dangerous. My wife was driving the vehicle in the grocery store parking lot when the power steering failed. She almost hit another vehicle while trying to pull into a space. She was not able to steer the vehicle and called me to help. I was able to drive it to the dealer with a great deal of effort. Ford's recall and software update were insufficient to resolve the problems with this faulty system. Ford knows the torque sensor in the steering column is prone to failure but offers a ridiculous software update which serves no purpose other than to tell you there is a failure. In our case we did not even receive the warning light. The dealer quoted me $1507. 00 to repair this issue. I called Ford customer service and was told the recall was closed because the vehicle had the software update, and there was no further assistance available. Unbelievable. Please take appropriate action regarding this important safety issue. It seems this electronic power steering system is also failing in other Ford models. Thank you.

My 2009 Mercury Mariner has lost its power steering capabilities. When researching online, it shows a recall based on the power steering. Records show a Ford dealer did the software update to remedy the problem. However, the car wasn't having any issues when this was done. Now that the car is experiencing the issue based on the recall, Ford says it's now out of warranty. I can't imagine I'm the only one out of 741,000 people who is having to deal with this problem. As it stands, the car's steering is manual. Ford needs to do something to satisfy their customers because it's unethical to fix a problem when there is no problem and turn your back when there is a problem.
