What can fail
An incomplete software update from a previous recall left the engine cover prone to becoming excessively hot during elevated idle conditions.
This page covers 6 recalls and 27 owner complaints for the 2021 Ford E-450.
For the 2021 Ford E-450, the dominant complaint pattern centers on the engine and brakes. On the engine side, owners, several of whom operate commercial fleets, report camshaft and lifter failures accompanied by a loud knocking or rattling noise, typically with no warning lights before the onset. In multiple cases, dealers replaced the engine entirely. Brake complaints describe the pedal becoming stiff and requiring sustained, heavy pressure to slow the vehicle, sometimes occurring alongside a stiff steering wheel. The steering complaints filed separately echo that same loss of assist, with owners describing the wheel becoming difficult to turn. The engine failures appear concentrated in vehicles equipped with the 7.3L engine, and several fleet operators report the problem affecting multiple units within the same purchase group.

By System
The 2021 Ford E-450 has 6 recalls, the most serious involving potential loss of both power steering and brake assist on dual-rear-wheel models, along with a driveshaft that can separate and a wiring fault that can stall the engine.
On dual-rear-wheel models, a loose connection between the power steering pressure line and the brake booster can suddenly drain power steering fluid, leaving the driver without power steering or power brakes. A separate drivetrain concern involves the rear axle differential, which may have been underfilled with fluid at the factory, causing the axle assembly to fail and the driveshaft to separate, resulting in sudden loss of drive power. There is also a wiring issue where a harness at the rear of the vehicle can rub against the frame and damage circuits serving both the fuel pump and the anti-lock braking system, which can cause the engine to stall unexpectedly or reduce braking performance. On the comfort and safety side, the engine cover inside the passenger compartment can run excessively hot due to mispositioned insulation, and contact with it can burn the skin of the driver or front passenger. A prior software update intended to address this engine cover issue did not fully resolve the problem for some vehicles, and those remain subject to the same burn risk.
