The 2013 Isuzu NPR HD has 4 recalls, the most serious being a stuck accelerator pedal that can lock at full throttle on gasoline-engine models, making the truck extremely difficult to slow or stop and raising the risk of a crash.
A second serious concern involves the left rear wheel assembly. The locking bolts securing the rear wheel bearing hub may not have been tightened properly during assembly, allowing the wheel to shift outward from the axle housing. That movement reduces braking performance and can make the vehicle harder to control. On the equipment side, both recalls cover an onboard fire extinguisher that may fail to work correctly in a fire, leaving occupants without a functional suppression tool when it is needed most.
