NHTSA Complaint #10644986 — 2011 FORD F-250

WHEN TRAVELING AT HIGHWAY SPEEDS, IF MY TRUCK HITS A RIDGE OR BUMP IN ROAD, IT STARTS SHAKING VIOLENTLY UP AND DOWN. I SLOW DOWN AND FIGHT THE WHEEL TO GET THE TRUCK TO THE SIDE OF THE ROAD. SO FAR, THIS HAS HAPPENED APPROXIMATELY 18 TIMES. MOST OF THE TIME, IT STOPS SHAKING AS I SLOW DOWN. TWICE IT STOPPED SHAKING AFTER I CROSSED TRAFFIC TO GET TO EDGE OF ROAD TO STOP. VERY SCARY! THE FIRST TIME IT HAPPENED, IT BOUNCED UP & DOWN SO HARD, IT PULLED THE WHEEL OUT OF MY HANDS. AS I GENTLY BRAKED TO SLOW DOWN, IT STOPPED BOUNCING UP AND DOWN, BUT THEN STARTED UP AGAIN WHEN I HIT THE NEXT EXPANSION SEAM ON THE ROAD. THIS HAPPENED ABOUT 6 TIMES ON MY WAY TO WORK THAT DAY. I WAS DRIVING APPROXIMATELY 30 MPH IN THE RIGHT LANE TO GET TO WORK IN A 65 MPH ZONE BECAUSE I WAS SCARED TO GO FASTER. TRAFFIC WAS ZOOMING AROUND ME AND HONKING. THE VERTICAL SHAKING DIDN'T HAPPEN AGAIN FOR ABOUT 3 MONTHS ALTHOUGH I TRAVELED THE SAME HIGHWAY WITH THE SAME BUMPS AND THE SAME SPEED (GRITTING MY TEETH). MY MECHANIC EXAMINED THE TRUCK 2 DAYS AFTER THE FIRST ROUND OF INCIDENTS AND FOUND NO PROBLEMS WITH THE FRONT END, STEERING, OR SHOCKS. NOTHING WAS LOOSE, BROKEN, OR OUT OF SPECS. I INFORMED FORD.COM ABOUT THE PROBLEM AND WAS TOLD TO TAKE THE VEHICLE TO THE DEALER. ALL OF THE DISCUSSION GROUPS SAID THAT THE DEALERS COULD NOT FIX THE PROBLEM. THERE SEEMS TO BE NO RECALL FOR THIS INCREDIBLY FRIGHTENING PROBLEM. I HAVE ALWAYS OWNED FORD TRUCKS (LAST TRUCK IS A 1996 F250 THAT WAS A WONDERFUL TRUCK - STILL HAVE IT). AS BACKGROUND, THERE ARE SEVERAL VIDEOS OF THIS HAPPENING ON YOUTUBE WITH SEVERAL DISCUSSION GROUPS TALKING ABOUT THIS PROBLEM. THE "DEATH WOBBLE" SHOWN IN THE VIDEOS IS THE SAME THING I EXPERIENCED. *TR
