Service bulletin N192288520

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Customer Satisfaction Program - Drivers of certain 2019 model year Chevrolet Silverado 5500HD/6500HD vehicles have reported harsh/rough/unacceptable ride quality from their vehicles. A combination of high capacity suspension components, relatively low curb weight and light front axle loading produces poor ride quality. Dealers will install updated cab mounts and shocks.
