Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2017 4500HD/4500XD Medium Duty.
The 2017 Chevrolet 4500HD and 4500XD Medium Duty serves as the starting point for the model's formal complaint history, which spans the 2017 through 2023 model years. Across this entire window, the highest number of complaints recorded in a single year is just one—occurring in 2021—making the peak of the model's issue tracking virtually negligible. As the inaugural year of this documented span, the 2017 model sits at the beginning of a highly stable reliability curve, meaning researchers will find no historical evidence of systemic defects or high-volume issues plaguing these early units.
