The 2012 Isuzu NPR has 5 recalls, the most serious being a stuck accelerator pedal on gasoline-powered models that can lock at full throttle and make the vehicle extremely difficult to stop, raising the risk of a crash.
A second serious concern involves the left rear wheel bearing hub, where loose locking bolts can allow the wheel assembly to shift outward from the axle, reducing braking performance and affecting vehicle control. On the electrical side, a software issue in the engine control module can prevent a faulty brake pedal switch from being detected, which means cruise control may not disengage when the brake is pressed. There is also a recall covering the onboard fire extinguisher, which may not function properly if needed during a vehicle fire.
