The 2012 Isuzu NQR has 4 recalls, the most serious involving the left rear wheel hub, where loose locking bolts can allow the wheel assembly to shift outward from the axle, reducing braking performance and vehicle control.
On gasoline-engine models, a calibration error in the engine computer software means the cruise control may not disengage when the driver presses the brake pedal if the brake pedal switch fails, leaving the vehicle holding speed when the driver expects it to slow. There are also two recalls covering the on-board fire extinguisher: the unit may not function properly in a fire, reducing the ability to suppress flames before they spread.

What the fix does
Dealers will reprogram the engine control module software at no cost to restore normal cruise control operation.
