The 2018 Isuzu NQR has 3 recalls, with two serious mechanical defects that can cause a loss of vehicle control: a steering failure on dual-steering-equipped models and a rear axle misalignment that can send the driveshaft to the ground.
On vehicles modified with dual steering, a small key piece inside the steering cross shaft can work loose, cutting off steering response to the right side of the system without warning. The second concern involves the U-bolts that clamp the rear axle to the leaf springs: if the nuts were not torqued properly at the factory, they can back off over time, letting the axle shift out of alignment. When that happens, the propeller shaft can separate from the drivetrain entirely, leaving the rear wheels without power and potentially stalling the truck in traffic. There is also a third recall involving a fire extinguisher that may not discharge correctly if needed, leaving occupants with non-functioning emergency equipment in the event of a fire.
