Driveshaft problems of the 2016 Ford F-250

The truck has the death wobble. I had dealer balance driveshaft 2x, as well as, the dealer adjusted the alignment again. . . The truck is still experiencing sustained steering wheel oscillation and I am again experiencing the death wobble, less than 1,000 miles after the most recent repair. It is very unfortunate that consumers purchase 50k+ dollar trucks and so many people are nervous driving them down the road. Ford keeps the montra up of such as the following: continuous improvement. Review the data, the data will tell the story. Change points. Root cause and permanent countermeasures. I have reviewed the historical f250 crew cab 4x4 complaint data on this site (NHTSA) and the data does tell a story. That story is very clear that Ford is not continuously improving the death wobble issue on the super duty, instead it has gotten worse. There has been a change point with this fourth generation f250. (2017,2018,2019) as of 11/21/19 the fourth generation f250 super duty has had more NHTSA suspension and steering complaints for the death wobble than the previous two generations combined. (9 years. Second generation 2008-2010 and third generation 2011-2016) the current repairs (countermeasures) are not effective and are not permanent. This can clearly be seen in the descriptions of the complaints on NHTSA. The repairs either do not fix the problem at all or are only a temporarily band aid for the issue. This is truly a safety concern and to date nothing has been implemented to correct the issue. Please, open an investigation and force Ford to permanently address the issue.
