Driving on Pa turnpike twice this year and at 70 mph my 2012 ford f 250 with 79000 miles on it started shaking uncontrollably , had my wife and granddaughter with me and they cried and screamed till it stopped. Going to the dealer to see what Ford is going to fix for me before someone is killed ! Hopefully a recall or free fix! I have been educated that this has been an on going issue in many F250 Fords.
