On 7/23/23 I experienced the death wobble in my 2014 F350 for at least the fifth time since purchasing the truck 4 years ago. This time was the most violent, scary and dangerous time of all. I was on an interstate, in heavy traffic, traveling at 65 miles per hour. Previous incidents have resulted in repairs to the suspension. Everything from tie rod ends, stabilizers and shocks. This most recent incident required that the steering damper to be replaced. All total, I have spent at least $3,000 in repairs in the last 4 years for this problem alone. Not to mention that I fear for me and my wife’s safety.

I have experienced three occurrences now where the vehicle suddenly begins to violently shake while driving between 50-70 MPH. All three times I was able to pull off the highway and stopped to inspect. Tires, lug nuts, brakes, and steering all appeared fine, so I cautiously resumed my trips without further incident. I have done some research and it appears that this is a well known issue, and is known as “Ford death wobble”. While I was able to safely move to the shoulder, I would be concerned if this occurred in heavy traffic, or if it occurred to an inexperienced driver. I am submitting this report to document these occurrences. During the last incident, I did get a traction control and hill descent malfunction indicator, but both of those cleared by themselves soon after resuming my trip. I am currently in the process of upgrading the steering stabilizer system, and replacing drag link, tie rods, ball joints to prevent any reoccurrences. While I understand these items are considered “wear” items, they should not be causing this severe of a problem at only 60k miles. (And I have no guarantee these will resolve my issue - I am replacing them as preventative measures)

I have experienced the "Death Wobble" numerous times. I have spent thousands of dollars since owning the truck chasing whatever we thought might be the issue. Ball joints, steering damper, tie rods/end, track bar, stabilizer bar, tires, the list is long. Stops for a time then starts up again. Death wobble consists of speeds over 60 mph and hitting bump and wheels wobble uncontrollably. This causes immediately slowing down until the wobble stops, however it is a violent shake and can pull the truck. Vehicles behind have no notice at immediate deceleration. Has not happen in the rain thank goodness.

2014 Ford F350 Super Duty Platinum 4x4 Diesel: Steering wheel started with small vibrations (90,000 miles), had Ford tell us that we needed a new track bar and bushing, so replaced it. Still having small vibrations in the 45-60 mph range. Then Ford said tie rod ends could be causing the problem did have some movement in the drag link, so replaced those, still having vibration. Had sound and clunking coming from steering box, so installed new steering box and pitman arm, and the small vibration has morphed into serious death wobble, and the pickup becomes almost uncontrollable until slowing down to under 45mph. Replaced all 4 shocks and the steering stabilizer. Sadly, the Ford dealership doesn't really seem to want to acknowledge there is a problem and work to fix it, and yet a quick internet search becomes extremely distressing quickly. To think, that you (NTSB) and Ford is likely going to wait until there is an accident before owning up to the fact that this is problematic and should be dealt with appropriately. They have offered to replace the steering stabilizer for 2017 or newer, even though they know it affects models as early as 2005. Clearly, neither you (NTSB) or Ford care about the people, it's just all about the dollar and CYA (Cover your [XXX]).

I have experienced an extremely violent vibration/wobbling of the vehicle at freeway speeds on several occasions. During these times, it is very difficult to control breaking, steering the vehicle, making it nearly impossible. I felt very unsafe not only for myself, but also other vehicles around me as I was driving a heavy-duty vehicle on the freeway at a high speed with essentially no control. Although I was shaken up, I was able to regain control of the vehicle and continue on my way. There have been no reports or inspections at this time. Prior to this happening, there were no warnings or messages. This happens twice in 2 days while driving on a long trip. Both times this occurred while driving at 65-70 mph and driving over a small bump in road.

We have experienced 6 episodes of severe “death wobble” in our 2014 350 diesel between mid Sept. and Nov 21, 2022. The truck shakes violently, 4 times while driving by around 60 mph on highways and twice while going slower on other roads. We have taken it into Ford Paso Robles twice: first time they could not identify the problem. The second time they said it was a “death wobble-Ford hates it when we call it that”; they charged us over $1200 to replace front shock absorbers and insulators, rear shock absorbers and steering stabilizer. The next time we put it on the highway, we had another severe death wobble as strong if not stronger than before. We limped home on HW 101 and HW 1 (with cliffs over the ocean), took it to James Ford Half Moon Bay who reproduced and confirmed the death wobble and said the entire front end needs replacement (parts alone, excluding new parts just put in by [XXX]) is $2962. I know Ford is aware of the death wobble problem and aware of strict product liability even for unknown defects. Our friend who bought a 2019 350 Ford received a recall notice for this issue but we haven’t. Ford needs to stand behind its product. We cannot drive this truck safely particularly since the only way to get to our home is off HW1 by steep cliffs.

This truck has exhibited the signs of ford's death wobble for the past 140,000 miles. The truck has been under fleet maintenance program since new from my employer and we have replaced all steer linkages, stabilizers, tires, and shocks multiple times over the past 140,000 miles and no improvements. Now when the truck hits a bump in the road, an expansion joint, or an overpass transition the front end will shake so violently that it has become uncontrollable. My girlfriend had this happen to her and it sprained her wrists trying to control the truck while coming to a stop. A few months back it happened to me the truck was bouncing so badly that it started to rotate around the vertical axis, and I feared that the truck would roll over as I had to bring it to a complete stop in the middle of the road. The truck had to be driven in the far-right lane so when you must make an emergency stop there is a shoulder to move on to and avoid being rear-ended. With the amount of Ford super-duty trucks o the road today and the number of them that are experiencing this issue, I am confused why Ford is not having to stand behind this product?

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.
