The 2014 Ford F-450 SD has 3 recalls, the most serious involving a PTO pressure switch that can leak oil onto the exhaust system, where heat from the exhaust can ignite the soaked insulation and start a fire.
On the suspension side, certain vehicles modified by Life Line Emergency Vehicles and fitted with Liquid Spring aftermarket suspension kits have a mounting bracket that can crack and release the suspension fluid tank from the frame, dropping it onto the road and creating a hazard for following traffic. Vehicles with ambulance or fire engine preparation packages face a separate powertrain concern: a fault in the transmission control module can cause the engine to shut down unexpectedly, requiring a cool-down period before the vehicle can be restarted, which can delay emergency response when time is critical.
