From reading about this issue I am having the same symptoms with my 2010 ford escape From reading about this issue I am having the same symptoms with my 2010 ford escape

Hope this helps. Only 1 person that I have come across, whose Ford dealership valued his business, replaced his without cost. The rest of us schmucks took it to the backside. One person in Canada replaced his under an extended warranty every 20,000 miles and yet a last one at a shared cost with dealership once it was out of warranty. They know it is happening and everyone thinks it is "only them" but in fact we know that there are a lot of us, at least those of us who search online for a fix. Here is the special service message found online.
