The 2019 Chevrolet 5500HD has 3 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.
The other two recalls involve rear axle hardware. Rear outer wheel lug nuts may not have been properly tightened at the factory and can work loose over time, allowing a wheel to separate from the truck while moving. Separately, the U-bolt nuts securing the rear axle may also be undertightened and can loosen enough to let the axle shift out of alignment, which can cause the driveshaft to separate and the truck to lose power and stall.
