The 2018 Isuzu NPR HD has 3 recalls, the most serious involving rear wheel lug nuts that may not have been properly tightened and can loosen until a rear wheel separates from the truck while driving.
A second chassis recall involves the U-bolt nuts that secure the rear axle to the leaf springs. If those nuts loosen, the axle can shift out of alignment, causing the driveshaft to separate and the vehicle to lose power and stall in traffic. The third recall covers an onboard fire extinguisher that may not function correctly when needed, leaving occupants without a working means to suppress a fire.
