On 3 occasions since I bought the pu new on july 24th, 2020 I experienced what the Ford dealer now calls death wobble. The first time happened on sept 2nd while driving down hill pulling my trailer at about 50mph. When I stepped on the brake the steering wheel and brake pedal started to shake violently. I had little control until my speed dropped. I took the pu to the dealer sept 16th. They said they could find no problem and stated if their agent could not experience the problem while driving the pu they could not fix it. On the second time I was driving the pu empty at highway speed and again while braking the steering and brakes shook violently. Up to this point I was thinking the brakes were the problem. I started tracking the brake temperature which showed a large variety of temps for

This has occured multiple times. While driving on freeway at speeds between 65 and 75 MPH and hitting rough asphalt, the vehicle begins shaking violently, almost to the point of losing control. It will only stop if I slow down to under 40 mph or stopping altogether. This has been very frightening when it occurs in traffic on freeways. It seems to occur mainly when on a curve.

12/09/2022 ODI #11496697.0

Repeated “death wobble” where the steering components oscillate rapidly left and right causing a lack of steering control. One repair attempted. Later occurrence and another repair. A third event, this time while pulling a 14,000 pound 5th wheel trailer. At about 63 mph the wobble started. I braked, the truck pulled left and I could not maintain my lane. An 18-wheeler behind me moved to the left lane due to my braking and we almost collided due to my not being able to steer. I did get it under control to get back in my lane and avoid the collision. This has been worked on by two different dealers and is about to be looked at again by the original dealer. Almost every front-end component has already been replaced.

Brought this truck on november 5,2020. It is a Ford f-350 super duty dually . On november 25,2020 the power steering went out couldn't steer truck then within a few mins. Lost the brakes on the truck. Had to hold brakes to floor to get truck stopped beside of road. Look like lost fluid from power steering . Was a good thing on a two lane road with little traffic. Was about to get on interstate highway where this would have been bad with all that traffic and going speed limit . Why would brakes go out if power steering quit?

11/19/2023 ODI #11555927.0

While traveling to and from New Orleans from New Jersey I had 12 incidents of the Ford Death Wobble. The first time I was traveling at 70 mile per hour when I hit a bump in the road and the wobble started. I was able to slow to about 30 miles per hour and the wobble stopped. Over the 2500 miles traveled I experienced this wobble at speeds as slow as 55 miles per hour. I will be taking my vehicle to the Ford dealer I purchased it from to see if they can help. Right now I am afraid to drive faster that 55 mile per hours for fear I my hit some kind of bump that will start this wobble and cause me to loose control of my truck.

Truck's power door lock actuators are failing and fail to unlock the doors via remote or the interior door(s) electric unlock button(s). The only way to open the door is via exterior key (if you happen to have it accessible) or if you pull the vehicle's interior door handle, which then "pops" the door lock button. This failure is alarming as in the event of an emergency, access to the interior cab of the vehicle can not be gained from the exterior without a key. Similarly, access to the interior of the cab can only be provided when one squeezes, or pulls, the vehicle's interior door handle. If a driver/passenger is incapacitated for some emergent reason, there is no easy way to gain rapid access to the passenger compartment without extrication type equipment. From my on-line research it ap

11/26/2020 ODI #11376452.0

Brought a new Ford super duty f-350 dually on november 5,2020. On november 6 2020, the passenger door caught behind the front fender, causing the passenger to not be able to open door. When we got door open , notice that the passenger door was out of line and had dropped down. The front fender was out of line with the door and hood. When door stuck it caused a dent in door and fender also chipped paint off. The issue is if passenger had to exit door in emergency without a lot of force it may not open properly or fast enough because of body parts way out of line. If a person was trying to open door from outside and it hung it could cause that person to loose grip of door suddenly and make them fall to ground causing injuries to them. Truck was not in motion when this occurred and parked in

In 2020 I Purchased Meyer Products Night Saber 4 LED Headlights for my snowplow. I thought they would be better than Meyers Nite Blaster 2 Halogen Headlights. Which I have found not to be the case. The Lens Defroster does not work well in heavy snow. They do not stay on constantly to keep melting snow off of the lens. Which becomes heavly snow laden severely impacting driving visibility. On more than one occasion I have had to pull over and manually clean the snow build up off of the lens. The most recent was the evening of Thursday [XXX] in which Maine had a heavy wet snow fall in Penobscot & Waldo County area. I had called Meyer Products in the past to complain about the the heater grid issue of not being able to keep up with keeping the lens clear & free of snow build up. I have

Dealer did changed the whole headlight assembly, however, the issue still there.

I have the 7.3 gas engine. It is now sounding like a typewriter. I've been told I could have a $8,000 to $13,000 repair or total engine replacement. My truck is just under 97,000 miles and this has been a known issue for the Job 1 engines. Ford is not taking ownership of these lifter/cam issue. I was told I could have my engine lock up on me while driving. I am autistic and have an autoimmune issue that cause me to have a disabilities. It does not seem right, that a long term, multiple Ford owner now could have their engine fail or lock up while I'm driving, not to mention I may need a complete new engine from this design error. From what I've read, the Job 2 of these engines they've enlarged oil recyclers or something to correct this issue. Can you help us that have this major saftey issu
