a) This guy knows nothing about diesel trucks and relies on the dealer. Recipe for disaster.
b) He purchases warranty because he thinks someone will take care of his truck. When something breaks warranty is denied. How predictable.
c) Dealer blames the issue on "a tune". They also blame lack of oil changes, wrong oil, water in the fuel, bad fuel. Customer has no power to argue.
c) When the 6.4L was released (after the 6.0L lemon) everyone said it was "bulletproof". 10 years later they are complete lemons. You can't even get 6.4L engines anymore.
The 2008-2010 Superduties with the 6.4L were throw away trucks. At 10 years they are worthless unless you are going to swap a Cummins in them. Resale value is zero because everyone knows the 6.4L is terrible.
The 6.0L trucks before the 6.4L trucks were throw aways. Unless you bulletproofed the engine yourself and even then they are questionable.
The early 6.7s (2011) dropped valves. They also blew turbos. There have been issues with the high pressure fuel pumps on them.

FYI, Cummins started using the CP4 on their 6.7L. There are threads in the TV forum about problems with it on Cummins engines.

Before you buy a 2020 diesel truck, listen to this podcast at the 26 minute mark. An engine rebuilder that works with cores from blown engines makes a comment about modern diesel engines versus 7.3, 5.9, etc.

Everyone thought the 6.4L was a great engine when it was 5 years old too. Now the the issues with the 6.7L are starting to surface. Ford has had made numerous changes to the 6.7L.
Notice the door fell off the bathroom in the trailer.
