Known issues on the 2023 F-350 Super Duty. Owners have filed 40 complaints with NHTSA, led by the electrical system, then structure and forward collision avoidance entries. Two of those three point at the truck's sensors and networks rather than at anything mechanical, and the manual's wiring diagrams, module descriptions and diagnostic procedures are where that work begins, alongside full coverage of all three V8s.
