2020 Chevrolet 4500hd Recalls — Canada & USA

The 2020 Chevrolet 4500HD has 4 recalls, the most serious being a brake fluid leak into the brake pressure switch that can cause an electrical short and start a fire while the truck is driving or parked.

Two recalls involve rear axle hardware that may not have been properly tightened at the factory. The rear outer wheel lug nuts can loosen and allow a wheel to separate from the truck entirely, and separately, the U-bolts securing the rear axle can also loosen, causing the axle to shift out of alignment and the driveshaft to detach, which cuts power to the rear wheels and can stall the vehicle. There is also a seatbelt concern: certain trucks equipped with a dual-mode belt locking mechanism have a front seatbelt that may not properly restrain an occupant in a crash, raising the risk of injury.
