NHTSA (USA)Medium Risk
At a glance
What can fail
The plastic-handle fire extinguisher may clog and fail to discharge, require excessive force to activate, or have a nozzle that detaches forcefully, potentially causing injury.
What the fix does
The 2012 Isuzu NPR has 5 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 high-priority issue involves the left rear wheel hub: the locking bolts that secure the wheel assembly to the axle may not have been properly tightened, allowing the wheel to shift outward from the axle housing. That movement can reduce braking performance and affect how the truck handles, both of which raise crash risk. On the electrical side, the engine control module software may fail to recognize when the brake pedal switch has stopped working correctly. When that switch malfunctions, pressing the brake pedal may not disengage cruise control, meaning the truck continues to hold speed even as the driver tries to slow down. There are also two recalls covering the cab-mounted fire extinguisher: the extinguisher may not function when needed, leaving the driver without a suppression tool if a fire breaks out in the vehicle.
