The 2020 Isuzu NPR XD has 3 recalls, the most serious involving loose rear wheel lug nuts and loose rear axle U-bolt nuts, either of which can cause a wheel or the driveshaft to separate from the truck while driving.
The lug nut issue means rear outer wheels may not have been secured to the axle with enough torque at the factory, allowing them to loosen over time and eventually detach entirely, which can cause a sudden loss of vehicle control. The U-bolt concern is related: the hardware clamping the rear axle to the leaf springs may also be under-torqued, allowing the axle to shift out of alignment. When that happens, the propeller shaft can separate, cutting power to the rear wheels and stalling the truck in traffic. The third recall involves the front seatbelt assembly on vehicles equipped with a dual-mode belt locking mechanism. The webbing or locking function may not properly restrain an occupant in a crash, raising the risk of injury to the driver or front passenger.
