FROM THE VERY FIRST DAY I GOT THE TRUCK WHEN YOU GO DOWN THE HIGHWAY AT A SPEED OF 60 OR HIGHER THE FRONT END SHAKES VIOLENTLY AND PULLS THE TRUCK TO THE LEFT. AND IT DOES IT TO THIS DAY 6YRS LATER. FORD KNOWS OF THE PROBLEM AND STATED IN A LETTER TO ME FROM FORD THAT 2006 F250 TRUCKS HAVE THIS PROBLEM AND IS DANGEROUS. BUT THEY HAVE NOT COME UP WITH A FIX FOR IT AS OF THIS DATE. IT WAS DANGEROUS WHEN I BOUGHT IT IN 2006 AND IT IS STILL DANGEROUS TODAY. YOU COULD POSSIBLY GO INTO ANOTHER LANE AND HIT ANOTHER CAR OR CROSS OVER INTO ON COMING TRAFFIC. FORD SHOULD BE MADE TO FIX THE PROBLEM AT NO COST TO THE OWNERS. *TR

THE CONSUMER STATED THE VEHICLE PERFORMS PERFECT WHEN NOT TRANSPORTATION A LOAD AT ANY SPEED ON ANY ROAD CONDITION. HOWEVER, WHEN TRAVELING DOWNGRADES OF 6% OR MORE WITH THE 5TH WHEEL TRAILER AT SPEEDS ABOVE 50 MPH, A LIGHT TOUCH OF THE BRAKES TO SLOW THE COMBINATION VEHICLE DOWN INITIATES THE OSCILLATION WHICH WILL NOT STOP THE UNTIL THE VEHICLE SPEED FALLS BELOW 50 MPH.

THE TRUCK NOW THREE TIMES IN LESS THAN 5 MONTHS HAS SHOOK SO BAD THAT WE COULDN'T HOLD ONTO THE STEERING WHEEL, WHEN JUST RIDING OVER A BRIDGE SEAM. THE TRUCK SHOOK SO BAD THAT THE CAR IN THE NEXT LANE RAN OFF THE ROAD AND WE ENDED UP IN THE MEDIAN. WE HAVE PURCHASED NEW TIRES AND WE CHECK OUR PRESSURE DAILY. WHICH HAS NOTHING TO DO WITH THIS ISSUE. SOMEONE IS GOING TO BE KILLED WITH THIS HYPER SHAKING. I KNOW IF THERE ISN'T SOMETHING DONE THERE ARE GOING TO BE ACCIDENTS. WE LIVE IN THE NORTHEAST WHERE WE HAVE SNOW AND ICE WITH THE ROADS IN THAT CONDITION WE WOULD HAVE NEVER BEEN ABLE TO CONTROL THE TRUCK IF WE WOULD HAVE BEEN ON ICE AND SNOW. LUCKY IT WAS NOT SNOWING AND IT WAS DRY PAVEMENT. I KNOW IF SOMETHING ISN'T DONE ABOUT THIS AND ALL THE OTHER COMPLAINTS THAT HAVE BEEN FILED FORD IS GOING TO BE SORRY WHEN SOMEONE IS KILLED. THE PROBLEM IS SO BAD YOU HAVE NO CONTROL OVER THE STEERING AND HAVE NO PLACE TO GO WHEN THIS HAPPENS. WE ALMOST SIDESWIPED THE CAR NEXT TO US THANK GOODNESS THEY WERE PAYING ATTENTION WHEN IT HAPPENED. THEY STOPPED AND ASKED IF WE WERE OK. THEY SAID THEY NEVER SAW ANYTHING LIKE THAT BEFORE. WE HAVE OWNED AT LEAST 6 F-150 TRUCKS AND 4 FORD EXPLORERS SO YOU COULD SAY WE ARE FORD PEOPLE. BUT I AM NOT SO SURE WE WILL STAY A FORD FAMILY SINCE THEY DON'T SEEM TO WANT TO DO ANYTHING TO REMEDY THIS ISSUE AND IT IS HAPPENING IN THE NEW ONES ALSO. WE HAVE A FRIEND THAT HAS A 2011 AND IT DOES THE SAME THING. I KNOW YOU HAVE DISMISSED COMPLAINTS BEFORE BUT SOMEONE IS GOING TO BE KILLED. THEN MAYBE SOMETHING WILL BE DONE BY YOU OR FORD WHEN THAT HAPPENS IT IS A SHAME THAT IT TAKES A DEATH TO MAKE SOMEONE DO SOMETHING. *KB
