## 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.
