WHILE DRIVING THE TRUCK GOING OVER 50 MILES PER HOUR, IT GOES INTO A WOBBLE, SHAKING, VIBRATION MODE. I FEEL LIKE I'M IN A EARTHQUAKE. SOME TIMES IT COMES ON JUST NORMAL DRIVING AND MOST OF THE TIMES HAPPENS DRIVING OVER BUMPY UNEVEN SURFACE AND POTHOLES ROAD DOING OVER FIFTY MILES PER HOUR. I HAVE TAKEN IT TO THE DEALERSHIP RED MCCOMBS IN SAN ANTONIO TEXAS ABOUT THREE OR FOUR TIMES BEFORE WITH THIS PROBLEM. THEY CAN'T FINE THE PROBLEM. THE SURVICE ADVISER DID STATE THAT ONE OF THERE TECHNICIAN DID KNOWDICE A SLIDE VIBRATION WHILE TEST DRIVING IT BUT OTHER THEN THAT NO PROBEMS. THEY DID REPLACE A PART AT ONE TIME BUT IT DID NOT SOLVE THE PROBLEM. I HAVE AN APPOINTMENT [RED MCCOMB] ON 6TH OF FEBRUARY TO DROP OFF THE TRUCK TO CHECK OUT AGAIN. I DON'T KNOW WHAT TO DO ANY MORE. THIS LAST TIME THE VIBRATION WAS REAL BAD. HAD HARD TIME GETTING IT UNDER CONTROL ON A MAJOR CITY HIGHWAY. I THOUGH I WAS GOING TO GET KILL. I FEAR FOR MY LIFE AND SAFETY DRIVING THAT TRUCK. I DON'T WANT TO SELL IT AND PUT SOMEBODY ELSE LIFE IN DANGER. I CALLED FORD MANUFACTURE ON AROUND THE 17 OR 18 OF JANUARY AND INFORMED THEM ABOUT IT. THE CONVERSATION WAS RECORDED ACCORDING TO THEM. THEY ACTED LIKE THERE HAS BEEN NO PROBLEM WITH THOSE TRUCKS. THEY CONTACTED ME BACK WITH THE DEALERSHIP. THATS WHEN I MADE THE APPOINTMENT. I BOUGHT THAT TRUCK NEW IN TEMPLE TEXAS FROM THE JOHNSON BROTHERS DEALERSHIP IN JUNE 2012. RED MCCOMB HAS MAINTAIN ALL OF THE REQUIRED MAINTANACE AND MECHANICLE PROBLEMS SINCE I BOUGHT IT NEW. JUST ABOUT EVERYTHING IS DOCUMENTRED THERE.

Known Ford Superduty "death wobble"...violent shaking of truck's front end at highway speed. Happens randomly and usually after hitting a bump or going over uneven road surfaces. Only way to stop wobble is to slow down to below about 50 mph, putting myself and others on the road at risk. Known Ford issue.

The truck is experiencing what is commonly referred to as the "Death Wobble." At around 55 mph, the vehicle starts to violently shake. It shakes the whole vehicle, especially the steering--the steering wheel severely shakes until I slow the vehicle slows down below 40 mph. From my research, I've found this is a common issue among other Superduty owners. It seems like there are faulty front end suspension and/or steering parts at play: pitman arm, drag link, tie rod ends (and their bushings/ball joints), etc. The shaking happens on the freeway and is frightening to experience as it could potentially lead to losing control if unable to slow down in time to stop the shaking. Being at freeway speeds, my family and I are at risk as well as other vehicles on the road if we were to lose control. This issue did occur 1.5 years ago. I took it into a Ford dealership where they replaced the steering dampener/stabilizer. Now the death wobble is happening again. From what I've learned, this is a band-aid fix that doesn't address the root cause of the death wobble. No warning lamps or error codes are present before, during, or after the shaking.

Extreme, violent shaking of the front end. At highway speeds, when it happens, the vehicle is very difficult to control while trying to slow down enough for it to stop. This is definitely a safety issue.

Okk Main issue is what everyone calls the “Death Wobble”. It has done it countless of times since I’ve had the truck. Even after I bought a New Fox Single steering stabilizer. I have replaced quite a few things under the front end that I was told “Could” be why it kept doing it. The most recent I’ve bought for the front is brand new Fox Shocks just like the ones I have on the back and it still does it. I’ve had the front end aligned a couple times since I’ve had the truck and rotated my tires once too. And to this day it Still does that death wobble. It scares me every time too still. Im afraid ima end up in a wreck or cause a wreck bc of it. Another issue is I keep having this warning pop up saying “ Engine Temp too high reduced engine power “ bc it thinks the engine coolant is too low which it’s Not. And when I scan the code through the OBD port it just says “Engine oil temp sensor too low/too high”. I had the Ford dealership in my town put a new Oil Temp sensor in it but it still throws a code just about everyday I drive it. Another issue I had was the High Pressure fuel pump on the front of the motor go out Literally while I was sittn in my driveway at night after just driving it not even 3 miles down the road to the store to grab a few things. And it ran fine like normal but soon as pulled in the driveway an was rolling my windows up about to go in it just died on me an had to get it towed to the Ford dealership in my town. They looked at my fuel an said my fuel was fine with No contaminants in it. I was just Unlucky they said so that was basically 10k out my pocket to pay for a Whole New fuel system. The Death Wobble is my most concerning issue but other than that the truck has been awesome.

While traveling at 55mph I hit a bump which caused the front of the vehicle to shake very violently. Rapid speed increase made it worse. It was only resolved when I braked hard slowing to 30mph. Thank goodness there was no traffic behind me as this would have resulted in my being rear ended by another vehicle.

The Office of Defects Investigation (ODI) opened this RQ to investigate allegations that the scope and remedy of safety recall 13V-535 were inadequate. Recall 13V-535 was limited to a relatively small population of Ambulance Package vehicles and ODI received complaints of pickup trucks and Fire Engine Prep Package vehicles being affected by the same defect. Ford manufactured approximately 555,985 subject vehicles between February 22, 2010 and January 30, 2015 that may be affected by defective EGT sensors and Powertrain Control Module (PCM) software calibration. The subject vehicles are equipped with four (4) EGT sensors to monitor engine operating conditions. An EGT sensor fault may produce false exhaust over-temperature signals. If these signals are produced, the Powertrain Control Module (PCM) implements a Failure Management Effects Mode (FMEM) and the driver receives a Stop Safely Now (SSN) system warning on the instrument cluster message center. The FMEM triggers a 70% reduction in available engine power over a period of no more than 45 seconds, during which it may not be possible to accelerate or maintain vehicle speed. The PCM then commands the engine to shut down when vehicle speed reaches approximately 1 mph. There is no immediate restart capability. Depending on the PCM software calibration, ignition key position and ambient temperature conditions, the engine may not restart until the end of a 10-60 minute cool down period.Ford and its component supplier(s) made numerous changes to the PCM software calibration and the design, material and manufacture of the EGT sensors over the period of subject vehicle production. This continuous product improvement affected vehicle performance regarding the alleged defect. Ford acknowledges the defect condition in the subject vehicles but argues that an unreasonable risk to motor vehicle safety is limited to Ambulance Package and Fire Engine Prep Package vehicles where commanded shutdown could impact emergency response and patient care. Ford also argues that the defect trend is in decline. Ford also initiated a new safety recall (15V-175) to address the 13V-535 remedy concerns in the Ambulance Package vehicles and Fire Engine Prep Package vehicles. The 15V-175 remedy reprograms the PCM with a new software calibration that stops a single EGT sensor fault to cause the vehicle to enter the FMEM shutdown mode.Ford also initiated an EPA emissions recall (14E03) for all subject vehicles that reprograms the PCM with the software calibration employed in safety recall 15V-175. Finally, Ford initiated a Customer Satisfaction Program (15M01) providing extended warranty coverage of 8 years or 80,000 miles for the the EGT sensors on certain MY2011-2012 subject vehicles.Due to the EPA emissions recall, that had a 66.6% completion rate in Ford's December 2015 progress report to the EPA, the defect trend is in decline. ODI is not aware of any crashes, deaths or injuries related to the alleged defect.ODI believes the alleged defect poses a safety risk but notes that the EPA emissions recall is addressing the safety problem.Compelling issuance of a duplicate recall would not represent a wise use of agency resources.Accordingly, this Recall Query is closed.This action is not a finding that no defect exists and NHTSA will take further action if such action is warranted.
