Known issues on the 2023 E450. Owners of the 2023 E450 have filed 15 complaints with NHTSA, and the engine draws the most at six, ahead of the power train at four and the electrical system at three. The federal record also holds four recalls for this model year. Certain 2023 E450 vehicles were recalled because the 48-volt ground cable connection in the engine bay might have been left loose, letting the cable overheat and raising the chance of fire; dealers inspect the connection and repair it as needed. Two separate campaigns covered certain cars whose fuel pump could shut down and cut drive power, and another addressed certain vehicles where a software fault could stop the exit warning system from alerting occupants to approaching vehicles. Procedures, torque values, wiring diagrams and diagnostics for these systems are in the manual.
