While driving 60 mph, in heavy rain, flat roadway the vehicle down shifted from 6th gear to 4th and from 6th gear to 3rd several times. The shift to 3rd from 6th was hard and accompanied by a temporary loss of forward momentum. No check engine light came on. All temperature gauges remained within normal range. The tachometer jumped and fell wildly during each of the events. I pulled off the highway at the next exit, turned off the ignition, and waited a few minutes. I restarted the truck and proceeded without additional problems.

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 purchased this pickup 3 months ago, and the engine light is on. The ford dealer has been working on it weekly, even talking with engineers from ford, but it still comes on after resetting. They have replaced the computer, wiring and sensor but it still shows the same code. The light comes on whether I'm towing or not going down the road.
