The 2020 Chevrolet 5500XD has 3 recalls, the most serious involving loose rear wheel lug nuts that can allow a rear outer wheel to detach from the vehicle while driving.
The rear suspension carries a related fastener concern: U-bolt nuts securing the rear axle may also be insufficiently tightened and can work loose over time, allowing the axle to shift out of alignment. When that happens, the driveshaft can separate, cutting power to the rear wheels and stalling the truck without warning. On the occupant safety side, certain vehicles equipped with a dual-mode belt locking mechanism have a front seatbelt that may fail to properly restrain the occupant in a crash, raising the risk of injury.
