What 560 owners told NHTSA about the 2017 Ford F-350 Super Crew

SEVERAL TIMES I HAVE EXPERIENCED SEVERE SHAKING WITH THE STEERING. IT FEELS AS IF THE FRONT OF THE TRUCK IS GOING TO FALL OUT. IT HAS HAPPENED AT SPEEDS BETWEEN 50 AND 70MPH. I HAVE TO STEP ON THE BRAKES TO THE POINT I AM AFRAID SOMEONE WILL HIT ME FROM THE BACK. SO FAR I HAVE BEEN ABLE TO KEEP CONTROL BUT IT SEEMS TO BE GETTING WORSE. I HAVE ABOUT 25,000 MILES ON IT. THE FIRST TIME THIS HAPPENED I HAD LESS THAN 15,000. THESE OCCURRENCES ARE FREQUENT NOW AND AS A RESULT I AM AFRAID TO DRIVE IT

DRIVING OVER EXPANSION JOINTS ON INTERSTATE AND TRUCK STEERING HAD A SEVERE WOBBLE, UNABLE TO CONTROL AND ALMOST HIT THE CONCRETE MEDIAN WALL. SLOWED DOWN ENOUGH TO STOP IT.

DEATH WOBBLE/UNCONTROLLABLE STEERING WHEEL OSCILLATION OCCURS AT SPEEDS OVER 55 MPH SHAKES SO BAD IT MAKES CONTROLLING THE TRUCK ALMOST IMPOSSIBLE. MUST REDUCE SPEEDS BELOW 20MPH OR TO A STOP TO GET IT TO STOP. DEATH WOBBLE HAPPENS WHEN I HIT A BUMP IN THE ROAD LIKE A POT HOLE, BRIDGE, MANHOLE, ETC. VEHICLE HAS VISITED A FORD CERTIFIED MECHANIC AND THEY HAVE INFORMED ME THERE IS NO FIX AND THEY HAVE 9, I REPEAT 9 TRUCKS IN FOR THE SAME ISSUE.

I'M APRIL OF 2018 THE ELECTRIC TAILGATE ON MY 2017 FORD F-350 STARTED OPENING ON ITS OWN ANYTIME AND ANYWHERE. IT DID NOT MATTER IF THE TRUCK WAS IN PARK OR IN GEAR BUT DID NOT OPEN AT SPEEDS ABOVE 10 MPH OR SO. AFTER GOING TO THE FORD DEALERSHIP IN ELKHART IN. I WAS TOLD THERE WAS NOTHING THAT COULD BE DONE BECAUSE IF THEY UNHOOKED THE WIRING L COULD NOT OPEN THE TAILGATE. I PULL A 5TH WHEEL TRAILER WITH THE TRUCK SO THIS WAS NOT AN OPTION IF L WANTED A TAILGATE. I TRIED TO WATCH THE BEST L COULD BEFORE TAKING OFF TO MAKE SURE THE TAILGATE WAS CLOSED WHEN L WOULD MOVE THE TRUCK. I DID NOT NOTICE THAT IT HAD COME DOWN AGAIN AND MADE A TURN WITH THE TRAILER HOOKED TO THE TRUCK. NEEDLESS TO SAY THE TAILGATE WAS CRUSHED BEYOND USE AND BROKE A TWILIGHT LENS AT THE SAME TIME. AGAIN L WENT TO THE FORD DEALERSHIP IN ELKHART IN AND WAS TOLD THEY HAD NO REPORTS OF PROBLEMS AND THERE WAS NOTHING THEY COULD DO ABOUT IT. THE TAILGATE HAS NOT BEEN REPLACED DO TO THE FACT L AM SURE THERE IS STILL AN IS SURE.

DRIVING AT APPROXIMATELY 45MPH OR GREATER, THE VEHICLES FRONT TWO WHEELS AND STEERING WHEEL WILL WOBBLE OR OSCILLATE RAPIDLY AFTER HITTING A POT HOLE OR EXPANSION JOINT. THE WOBBLING JARS THE STEERING WHEEL AND MAKES THE VEHICLE HARD TO CONTROL. BREAKS MUST BE APPLIED AND SPEED REDUCED BY 5 TO 20 MPH TO STOP THE WOBBLE.

I OWN A 2017 FORD F350 THAT HAS EXPERIENCED DEATH WOBBLE. WHICH IS A VIOLENT SHAKING AND VIBRATING IN THE FRONT END. WHEN IT HAPPENS, THE FRONT END SHAKES SO BADLY, YOU CANNOT EVEN CONTROL THE VEHICLE. MY TRUCK ONLY HAS 20,000 MILES ON IT, AND THIS SHOULDN'T BE HAPPENING. IT HAPPENS WHEN DRIVING ON A STRAIGHT ROAD, WHEN TURNING, WHEN HITTING A BUMP, GOING FAST OR GOING SLOW. I KNOW MANY OTHER FORD OWNERS HAVE REPORTED THEIR DEATH WOBBLE, SO I AM JOINING THEM. SOMETHING NEEDS TO BE DONE.

UPON COLD START, THE AT IN 'M' MANUAL MODE, FIRST GEAR OR 'R', EITHER 4WD LO, HI OR 2WD, WHEN ACCELERATED UP TO 1500-1800RPMS, VEHICLE WILL ACCELERATE BY ITSELF, WITHOUT OPERATORS FOOT ON ACCELERATOR INCREASING SPEED AND RPMS APPROACHING 4000 RPMS. BRAKING IS POSSIBLE AND WILL SLOW TO IDLE RPMS SAFELY, BUT IF INCREASED AGAIN WITH FOOT ON ACCELERATOR TO 1500-1800 RPMS, SYMPTOM WILL REPEAT UNTIL WARMED UP THRESHOLD HAS BEEN REACHED. THIS IS BETWEEN 3-5 MINUTES AFTER COLD START. ALL IS NORMAL AFTER THIS TIME AND VEHICLE WILL NOT INCREASE IN SPEED BY ITSELF. IF VEHICLE SITS FOR 2-3 HRS, SYMPTOM CAN BE REPEATED. OUTSIDE TEMPERATURE DOES NOT SEEM TO PLAY A FACTOR. IT IS MOST EASILY EXPERIENCED IN 4WD LO, AS THE SPEED IS LOWER, YET THE RPMS ARE THE SAME AS IN 4WD HI OR 2WD. I FIRST EXPERIENCED THIS WHEN BACKING UP (IN 'R') IN 4WD LO AFTER A COLD START AND HAD TO INCREASE SPEED AND RPMS BEYOND 1500 WHEN VEHICLE STARTING INCREASING IN SPEED BY ITSELF. I WAS ABLE TO BRAKE AND NO DAMAGE OR INJURY OCCURRED. I HAVE SINCE EXPERIMENTED TO DETERMINE EXACTLY WHEN THIS SYMPTOM OCCURS.

STEERING WOBBLE (SOME CALL IT DEATH WOBBLE) ON CARTOON BUMPS IT APPEARS T INDUCE A UNCONTROLLABLE WO BUE IN FRONT WHEEL STEERING. WHEELS WILL ISOLATE FAST AND VIOLENTLY UNTIL VEHICLE SLOWS. MY VEHICLE SO FAR HAPPENS INT HE 55 TO 60 MPH RANGE AND COASTING WITHOUT USING BRAKES IT WILL DISCONTINUE BEFORE 40MPH. I NOTICE ON THE HIGHWAY THAT I HA E EXPERIA CEDAR THIS (3 TIMES SO FAR) THAT SEVERAL OF THE TYPICAL CROSS RIDGES CAUSED BY GROUND HEAVE OR FREEZING WILL MAKE STEERING WHEEL SHALE LIKE 3 TIMES. THIS IS NOT NORMALLY EXPERIANCED ON MOST SMOOTHER BLACK TOP ROADS. I FEEL THE 3 SHAKES ARE A PRE-WOBBLE ACTION AND WHEN A BUMP MAYBE IS REPEATED IN CARTOON DISTANCE MAYBE IT MAKES THAT 3 SHAKE I'VE FEEL CROSS THE CONTROLLED STEERING POINT AND THIS SHAKE/WOBBLE HAPPENS. I HAVE ONLY HAD THE WO BUE HAPPEN WHILE GOING STRAIGHT BUT HAVE FELT THIS 3 SHACK PRE-WOBBLE SEVERAL TIMES WHEN IN A CURVE AND FEEL LIKE IT COULD DO IT IN A CURVE ALSO SHOULD THE NEEDED TRIGGER BUMPS BE THERE. I DO NOT HAVE PHOTO OR VIDEO DO HOPE TO MOUNT CAMERA AND HAVE A VIDEO SHOULD IT REPEAT IN THE FUTURE. FORD DEALER 1ST VISIT FOU D NOTHING BUT FELT THEY COULD CHANGE ALIGNMENT BUT NEEDED TO ORDER A SHIM I BELIEVE. 2ND VISIT REALIGNED USING A SHIM AND CHANGE STEERING DAMPNER. 3 RD VISIT SAME ANSWER BUT SHIMS ON BACKORDER WILL CHANGE PAST 3/4 DEGREE ADJUSTMENT TO 1 DEGREE. HOPE TO KNOW MORE ABOUT THIS ADJUSTMENT WHEN THEY ARE ABLE TO DO IT.. SERVICE SHOWED ME A SERVICE BULLETIN OUTLINING THESE STEPS TO SOLVE ISSUE.

TWO ISSUES.: 1) I HAD A HARD TIME KEEPING THE TIRES INFLATED TO THE CORRECT LEVELS. AFTER FOUR OR FIVE TRIPS BACK TO THE DEALERSHIP, THIS ISSUE MAY BE CORRECTED. IT WAS SO BAD I HAD TO PURCHASE A PUMP TO MAKE SURE I COULD PUMP THE TIRES UP WHEN I WAS AWAY FROM HOME -- RVING. THE DEALERSHIP WOULD HAVE TO HAVE KNOWN ABOUT THE ISSUE WHEN THEY SOLD ME THE VEHICLE. THE TRUCK COULD LOSE 30 POUNDS OF TIRE PRESSURE OVER A TWO WEEK PERIOD. I PURCHASED THE TRUCK IN MARCH 2018. 2) ON FOUR OR FIVE OCCASIONS THE TAILGATE HAS FALLEN OPEN. ONCE IT DID IT WHILE I WAS TOWING A TRAILER. ON THE OTHER OCCASIONS IT HAS FALLEN OPEN WITHOUT US KNOWING IT. TODAY, MY WIFE USED THE TRUCK. SHE GOT HOME AND PARKED THE TRUCK IN THE DRIVEWAY. WHEN SHE WENT OUT TO CHECK THE MAIL, SHE FOUND THE TAIL GATE OPEN. WE RECENTLY COMPLAINED TO FOX FORD, THE DEALERSHIP THAT SOLD US THE TRUCK. WHEN MY WIFE TOOK THE TRUCK IN FOR AN OIL CHANGE, SHE COMPLAINED ABOUT THE TAILGATE ISSUE. THEY CLAIMED THEY "TIGHTENED IT" ACCORDING TO MY WIFE. WELL, THE PROBLEM HAS NOT BEEN SOLVED. I WILL COMPLAIN AGAIN TO THEM TOMORROW.

ON NOV. 7 AND NOV. 24, 2018 WHILE DRIVING MY 2017 F350 SUPER DUTY DIESEL TRUCK I CROSSED FREEWAY BRIDGE TRANSITION STRIPS AT 70MPH, AT WHICH TIME THE FRONT END OF THE TRUCK WENT INTO WHAT IS COMMONLY REFERRED TO BY OWNERS AS THE "DEATH WOBBLE". THE FRONT END OF THE TRUCK BEGAN TO VIOLENTLY SHAKE UP, DOWN AND SIDEWAYS. THESE VIOLENT VIBRATIONS WERE OBVIOUSLY FELT IN THE STEERING WHEEL, WHICH ALSO BEGAN TO VIOLENTLY SHAKE, NEARLY TAKING THE WHEEL OUT OF MY HANDS WHEN THE EVENT FIRST STARTED. THE VIBRATION DID NOT STOP UNTIL I WAS OFF ON THE BERM AND REDUCED SPEED TO APPROXIMATELY 30 MPH. THESE OCCURRENCES OBVIOUSLY CAUSED NOT ONLY A SAFETY HAZARD FOR ME, BUT FOR EVERY VEHICLE BEHIND OR BESIDE ME AT THE TIME. THE ONLY WAY TO STOP THE PROBLEM IS TO IMMEDIATELY REDUCE SPEED, WHICH IS EXTREMELY DANGEROUS AT HIGHWAY SPEEDS OF 70 MPH, EVEN MORE SO IF TOWING A TRAILER OR CAMPER. THIS ISSUE CAN VERY EASILY CAUSE VEHICLES WITH THIS ISSUE TO LOSE CONTROL RESULTING IN AN ACCIDENT. THIS PROBLEM IS WIDELY KNOWN, GOING BACK YEARS, AND OWNERS HAVE SAID TSB 18-2268 DOES NOT CORRECT THE PROBLEM. FORD NEEDS TO CORRECT THIS PROBLEM, AND OWNER'S ONLINE DON'T UNDERSTAND WHY THE NHTSA ALLOWS THIS PROBLEM TO PERSIST.

2017 FORD F-350 DRW 4X4. WHILE DRIVING ON US HWY 67 IN ARKANSAS (A VERY ROUGH ROAD) AT 60 MPH, TOWING A 15K LB 5TH WHEEL RV, ENCOUNTERED A BUMP IN THE ROAD AND SUBSEQUENTLY EXPERIENCED A SUSTAINED STEERING WHEEL OSCILLATION THAT LASTED APPROXIMATELY 15-20 SECONDS UNTIL SPEED WAS REDUCED TO APPROXIMATELY 30 MPH AND STABLE OPERATION RESUMED. THIS OSCILLATION HAS BEEN EXPERIENCED IN THE PAST A FEW TIMES, BUT ONLY FOR 1-2 SECONDS AND ALWAYS AFTER EXPERIENCING A BUMP IN THE ROAD. I PRESUME THIS PROBLEM IS THE SAME AS WOULD BE COVERED BY FORD TECHNICAL SERVICE BULLETIN 18-2268 31 AUG 2018

DRIVING AT 65-70 MPH ON A CONCRETE PAVED HIGHWAY. HIT A ROUGH PATCH OF PAVEMENT OR EXPANSION JOINT, AND THE FRONT END BEGAN SHAKING VIOLENTLY, AS IF ONE OR BOTH OF THE FRONT TIRES HAD FLATTED. I COULD SEE THE HOOD SHAKING. THE STEERING WHEEL ALSO OSCILLATED SIGNIFICANTLY. I LET OFF THE ACCELERATOR AND LIGHTLY BRAKED TO ABOUT 45MPH BEFORE THE SHAKING AND OSCILLATION STOPPED. THIS OCCURRED ON DECEMBER 7, 2018.

I'VE EXPERIENCED A PROBLEM TWICE WITH MY 2017 F350 SUPER DUTY TRUCK CALLED THE "DEATH WOBBLE." AT HIGHWAY SPEEDS HITTING AN UNEVEN ROAD SURFACE, MY TRUCK FRONT WHEELS BEGIN TO SHAKE UNCONTROLLABLY. I MUST IMMEDIATELY SLOW TO A STOP TO END THE WOBBLE. MY TRUCK HAS LESS THAN 6K MILES, SO IT ISN'T BECAUSE OF ANY WORN PARTS. I FOUND OUT VIA THE INTERNET IT IS A COMMON PROBLEM WITH FORD SUPER DUTY TRUCKS.

AT 10,000 MILES THE TIRE PRESSURE SENSOR VALVE STEMS BEGAN LEAKING WHILE THE TRUCK WAS STATIONARY OR DRIVING CAUSING LOW TIRE PRESSURE. I HAVE HAD THE TRUCK IN TO HAVE THEM REPLACED 11 TIMES AND THE ISSUE STILL PERSISTS. FORD RESPONDED SAYING THE PROBLEM WAS A DEALER ISSUE NOT THEIRS.

2017 F350 SUPERDUTY DRW, 27000 MILES. WHILE ON THE FREEWAY AT 65 MPH, THE STEERING WENT INTO AN UNCONTROLLABLE VIBRATION (DEATH WOBBLE). THE ONLY SOLUTION WAS TO REDUCE SPEED TO APPROXIMATELY 10 MPH. CONTACTED THE DEALER AND FORD'S CUSTOMER SERVICE, AND WAS INFORMED THAT IT MUST BE WITNESSED BY AN OFFICIAL SERVICE TECHNICIAN BEFORE ANY ASSISTANCE COULD BE RENDERED.

ON 7/22/18, MY 2017 F350 (CREW CAB, LONG BED, DIESEL) EXPERIENCED WHAT IS APPARENTLY BEING CALLED "DEATH WOBBLE" 4 TIMES WITHIN 20 MINUTES, WHILE DRIVING ON INTERSTATE I-15 NORTH OF SALT LAKE CITY, UT. THE TRUCK HAD APPROXIMATELY 27,800 MILES ON IT AT THE TIME. IN FIRST INSTANCE, MY SPEED WAS ABOUT 65 MPH, AND IN THE FOLLOWING 3, IT WAS BETWEEN 50-60 MPH. THE SECTION OF HIGHWAY WAS BUMPY IN ALL CASES. THE SYMPTOMS WERE EXTREME AND VIOLENT VIBRATION COUPLED WITH VIRTUALLY UNCONTROLLABLE STEERING, WITH THE ENTIRE FRONT END OF TRUCK (AND STEERING WHEEL) SHAKING VIOLENTLY, PRACTICALLY BOUNCING UP AND DOWN. BRAKING DID NOT STOP THE SHAKING, AND SEEMED TO MAKE IT WORSE. IT WOULD NOT STOP UNTIL I HAD COASTED AND VERY CAREFULLY APPLIED BRAKES UNTIL I GOT BELOW 20 MPH. FORTUNATELY, THE ROAD WAS STRAIGHT IN ALL 4 OCCURRENCES, OR I FEEL I WOULD HAVE GONE OFF THE ROAD. UPON EXITING INTERSTATE AND INSPECTING FRONT END, I NOTED THAT THE "DEATH WOBBLE" HAD ACTUALLY TORN SMALL CHUNKS OUT OF MY FRONT TIRES (OEM GOODYEAR WRANGLER AT, LT275/70R18E), ALONG WITH OTHER CRACKS AND DIVOTS; THERE WAS NO SUCH DAMAGE TO THE REAR TIRES. I DID NOT DRIVE IT OVER 40 MPH AFTER THAT, UNTIL I HAD TAKEN IT TO A LOCAL FORD DEALER TO BE INSPECTED THE NEXT DAY. THEY SAID IT NEEDED AN ALIGNMENT, AND REPLACED THE TIRES, AND SINCE THEN IT HAS NOT REOCCURRED. THIS HAD ACTUALLY HAPPENED ABOUT 3 TIMES PRIOR TO THIS, OVER THE SPAN OF 3 MONTHS, WITH WEEKS BETWEEN, UNDER SIMILAR DRIVING CONDITIONS, BUT I INCORRECTLY ASSUMED IT WAS JUST DUE TO COMBINATION OF STIFF SUSPENSION AND ROUGH ROAD. I OWN AND TOW AN RV, AND IT HAS NEVER HAPPENED WHILE TOWING, REGARDLESS OF SPEED (I NEVER EXCEED 65 MPH WHEN TOWING.) WHEN THE DEALER SERVICED THE TRUCK, THEY DID NOT ACKNOWLEDGE THE PROBLEM AND SAID THEY COULD NOT REPRODUCE IT, BUT I DO NOT BELIEVE THEY DROVE IT OVER 45 MPH IN TEST DRIVING.

2017 F350 KR SRW LWB 21500 MILES OVER THE LAST 1000 MILES OR SO I HAD NOTICED A LITTLE SHIMMY IN THE STEERING WHEEL WHEN I'D GO OVER A ROAD CUT, A PATCH, OR EXPANSION JOINT. WELL TODAY I HIT ONE AT AROUND 70 MPH GOING STRAIGHT ON THE INTERSTATE AND THE STEERING WHEEL JUST WENT FREAKING BIZERK. IT STARTED OSCULATING BACK AND FORTH REALLY QUICK. I TRIED TO JUST GRAB IT AND HOLD IT STILL TO NO AVAIL. EASED ON THE BRAKES AND TRIED TO GET TO THE SHOULDER WITH TRAFFIC BEARING DOWN ON ME. AT 45 MPH IT STILL HADN'T LET UP.. AS I HIT THE SHOULDER AT AROUND 40 IT FINALLY QUIT SHAKING.

YESTERDAY WHILE CROSSING A BRIDGE MY TRUCK STARTED SHAKING VIOLENTLY AND UNCONTROLLABLE UNTIL I HAD SLOWED TO BELOW 45 MPH. THIS 'DEATH WOBBLE' AS IT IS KNOW IS VERY DANGEROUS. LUCKILY NO CARS WERE NEAR ME AND I WAS ABLE TO LET OFF OF THE THROTTLE AND HOLD ON TO THE STEERING WHEEL UNTIL THE TRUCK STOPPED SHAKING.
