The 2018 Isuzu NRR has 3 recalls, the most serious being two separate issues that can cause sudden loss of vehicle control: a rear axle that can shift out of alignment and drop drive power, and a steering defect on dual-steering-equipped units that can cause unexpected loss of right-hand steering.
On the chassis side, the U-bolt nuts securing the rear axle may not have been tightened to spec and can work loose over time, allowing the axle to shift out of position. When that happens, the driveshaft can separate from the drivetrain, cutting power to the rear wheels and stalling the truck without warning. The steering concern applies only to vehicles that were modified with a dual steering setup: a small keystock piece inside the steering cross shaft can dislodge, leaving the driver without right-hand steering input. There is also an equipment concern: the on-board fire extinguisher may not function correctly, which reduces the ability to suppress a fire if one breaks out in or around the truck.
