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 appears that Ford has had previous problems with this and actually acknowledge this through Ford Customer Satisfaction Program(s) 20M04, 19N06, 18N03. Appreciate any assistance and insight you may be able to provide.

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.

"Death Wobble"- At a speed of run 50 miles per hour. Going around the curve my steering will begin to shake violently. Also a handful of other times it shook in the same way after hitting a bump in the road. Once I slowed down it corrected itself.

My truck is a 6.2 liter gas engine with the same Transmission 10R140 built in the same plant and same time frame as the safety recall 22S22 as stated in this letter attached.

The letter from Ford written by David J Johnson director of service engineering operation, dated September 23, 2022. This letter stated trucks built in the Kentucky Truck assembly plant between October 1, 2019 through September 21, 2020 the 10R140 transmission the pinion thrust washers can disintegrate with a defected part. Per the Vin number my truck was built at the above Kentucky plant on February 20, 2020 with this 10R140 Transmission. My Truck is built with a 6.2 L gas engine with the 10R140 transmission F350 Super Duty. The service tech said this is the same Transmission put in the diesel engine trucks.

There is no way to secure cargo or equipment is side the cargo bed as the tailgate will not hold the tailgate up and keep secured and closed. It appears that Ford will not cover the electronic tailgate door latches but just the electrical components that control the electronic release. The latching mechanism should also be replaced along with the electronic wiring. This is a safety concern because if I carrying any type of cargo. The cargo may leave the truck bed.
