Known issues on the 2020 E450. Owners have filed 11 complaints about the 2020 E450, and back-over prevention tops the list with four, followed by structure and engine; one complaint reported a fire and one an injury. The federal record also holds eight recalls for this year. One reached certain vehicles whose rearview camera image could fail to appear because of a software fault. Another covered certain gasoline-engine cars in which debris caught between the fuel rail and injectors during assembly could let fuel escape near hot parts. A third concerned certain cars equipped with electrically released rear seatbacks, where the left-rear latch might give way if cargo struck it. Camera, fuel injection and seat latch work is backed by specifications, torque values, diagrams and diagnostics.
