My father in law has a 2009
My father in law has a 2009 MKZ. The acceleration problem has happened three times..fortunately only one of the incidents resulted in a minor fender bender. The first time he only had the standard floor matt. The next two time he had another matt over the factory floor mat, however there is no way it bunched up and effected the gas pedal. There is a significant amount of space between the bottom of the pedal and the floor mat. The floor mat argument is not the root cause of this problem. Ford needs to to look at this from a more technical angle.
