Leaving home to go to the grocery store and as I exited my street a dash warning came on stating "Power Steering Assist" fault Steering wheel locked up making it impossible for me to steer. Fortunately this happened in a spot where there was no other traffic and I was able to just turn off the car and restart and the message was gone and my steering was restored. I am now terrified to drive my car because if this had happened in traffic there could have been a serious accident because steering capability was non existent. . In reading online this is a very common problem with my make and model and apparently there was a recall by Ford for 2011 and later cars but not 2010 even though it is a "known problem" at dealerships. For me this now seems intermittent but in calling the dealership they know of the issue. It would cost me about $2200 to fix. I am happy to provide my vehicle for inspection. Thank you so much for your help ... greatly appreciated
