Upon taking off, in a busy intersection during lunch time traffic in town, a "steering assist failure" and chime came on at the same time the power steering failed. While the steering was just shy of locked, I was able to avoid hitting oncoming traffic and aim the Explorer into a parking lot directly in my path. I put on my hazards (they should come on automatically in such instances) and the other motorists were kind and allowed me to do so since traffic around and behind me had to come to a stop. Even at a healthy 250 lbs and 6'4", it was a serious struggle to make even a small change in the angle of the steering wheel. The Explorer is my wife's vehicle and I just happened to be with her that day, prepping the vehicle for our son to take over as his since he starts college in the fall. I shudder to think what could've happened had either of them been driving it when this happened. There were no prior indications, no odd noises, no roughness in the steering, no flashes of imminent failure, no notice of the possibility of this happening from Ford, just the sudden and dangerous loss of steering. We've owned this vehicle since it had ~54,000 we've loved the whole time, but this incident has caused us to lose faith in it. Even repaired, I don't see myself putting my wife or son into it with any confidence in their safety.
