The 2004 Ford E-150 has 5 recalls, the most serious being two separate fire risks: a short in the anti-lock brake module that can overheat and produce smoke or ignite, and an air filter element that can catch fire under the hood during normal driving.
The ABS module issue involves a failing diode that can either disable the anti-lock braking system entirely, which the dashboard warning light will signal, or generate enough heat to cause a fire under the hood. The air filter concern is separate: hot carbon particles from the engine can reach the filter and ignite it, potentially spreading fire to other components in the air intake system.
The remaining recalls center on aftermarket adaptive equipment installed on certain converted vans. Vehicles equipped with a VMI/Ricon six-way power seat base may have a faulty weld on the pivot pin that holds the seat's swivel plate. If that weld breaks, the seat can shift unexpectedly and injure the occupant. Two related recalls cover Ricon platform-style wheelchair lifts fitted to some converted E-150 vans: in both cases, the lift can begin to stow or move on its own without being commanded to do so, which could injure anyone on the platform at the time. These adaptive equipment recalls apply only to vans that were converted and equipped with this specific aftermarket seating or lift hardware.
