NHTSA Complaint #10269838 — 2006 FORD F-350 SD

I HAVE A 2006 FORD F350 CREWCAB SUPERDUTY THAT HAS A SHIMMY / VIBRATION IN CAB OF TRUCK WHICH HAPPENS WHEN I HIT A DIP OR BUMP AND IF I SLOW DOWN SOMETIMES IT GOES AWAY QUICKLY WHEN I SLOW DOWN AND SOMETIMES I HAVE SLOW DOWN BELOW 30MPH. HOW SAFE IS THAT ON AN INTERSTATE? I DID RECEIVE A LETTER FROM FORD SAYING THIS COMMON BUT I DISAGREE BECAUSE THIS IS MY THIRD SUPERDUTY AND THE LAST TWO I DID NOT EXPERIENCE THIS PROBLEM BUT THEY HAD DIESEL ENGINES THIS IS GAS. MY DEALERSHIP TOLD FORD CUSTOMER REP THAT I NEED A ROAD WORTHY TEST OR THE DRIVE SHAFT IS OUT OF BALANCE SO THEY ARE GUESSING TOO. THE DEALERSHIP DID NOT EVEN KNOW ABOUT THIS LETTER THAT FORD SENT TO SUPERDUTY OWNERS. FORD REP STATED THERE IS NO RECALL ON THIS VEHICLE. THE SERVICE MANAGER AT THE LOCAL DEALERSHIP BELIEVES THE PROBLEM IS BECAUSE A GAS ENGINE IS TOO LIGHT AND THE SUPERDUTYS WERE MADE FOR DIESEL ENGINES. I HAVE NO IDEA HOW TRUE THIS IS BUT MY FIRST TWO SUPERDUTY TRUCKS I HAD WERE DIESEL AND I DID NOT EXPERIENCE THIS. I HAVE DRAFTED UP A LETTER TO SEND TO NYS ATTORNEY GENERAL AND TO FORD BUT I AM NOT VERY CONFIDENT ABOUT THE END RESULTS. MY WARRANTY HAS RUN OUT AND NOW IT IS ON MY NICKEL. I EVEN PUT NEW E RATED TIRES ON THE TRUCK IN DECEMBER AND HAS BEEN AT THE DEALERSHIP TWICE WHICH THEY SAID THE TIRES WERE OUT OF BALANCE AND NEEDED TO BE ROTATED. I HAVE LESS THAN 3,000 MILES ON THESE TIRES SO THAT DID NOT MAKE ANY SENSE. AS OF THIS DATE THE TIRES HAVE BEEN BALANCED A TOTAL OF THREE TIMES WHICH ABSOLUTELY NO SENSE EITHER. I AM GOING TO GET A SECOND OPINION FROM MY MECHANIC THAT I HAVE BEEN USING FOR OVER 20 YEARS WHICH IS NOT A FORD DEALERSHIP TO SEE IF THE PROBLEM CAN BE RESOLVED SINCE I AM NOT GETTING MUCH HELP FROM FORD OR THE DEALERSHIP. THIS SHIMMY / VIBRATION DOES GET ME NERVOUS AT TIMES AND DO NOT FEEL I AM VERY SAFE IN KEEPING THIS BIG PICKUP UNDER CONTROL AND I DO NOT EXCEED THE SPEED LIMIT MORE THAN 5 MPH. I HAVE BEEN A FORD PERSON FOR OVER THIRTY YEARS AND NOW I MAY HAVE TO CHANGE. *TR
