The 2012 Isuzu NPR HD has 4 recalls, the most serious being a stuck accelerator pedal on gasoline-engine models that can lock the throttle wide open, making the truck very difficult to stop.
The left rear wheel bearing hub also has loose locking bolts that can allow the entire wheel assembly to shift outward on the axle, reducing braking performance and making the truck harder to control. There is also a recall covering the fire extinguisher included with the truck, which may fail to function properly in a fire.
