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 2015 Isuzu NPR HD has 5 recalls, the most serious being a stuck accelerator pedal that can cause the truck to accelerate uncontrollably and become difficult to stop, raising the risk of a crash.
The second high-priority concern involves the left rear wheel. The hub locking bolts may not have been fully tightened at the factory, allowing the entire wheel assembly to work its way outward from the axle. If this happens, the driver loses full steering and braking control, which can lead to a crash. On the structural side, the crossmember that supports the transmission may have developed small sharp burrs from the stamping process during manufacturing. These burrs can cause the transmission mounting studs to break, leaving the transmission unsupported and unable to shift correctly, again increasing crash risk. There are also two recalls covering the fire extinguisher that ships with certain NPR HD trucks: if the extinguisher fails to discharge properly when needed, a fire cannot be suppressed, raising the risk of injury to the driver or anyone nearby.
