Summary Verdict
The 2021 Mercedes-Benz Sprinter 3500XD demonstrates solid reliability, particularly in its chassis and core mechanical components. The primary areas of concern tend to be related to the emissions control systems (DPF and AdBlue) for the diesel engines, and occasional glitches with the infotainment system. The V6 diesel, while powerful, can be more prone to turbocharger and EGR issues than the 4-cylinder. Transmission issues are not widespread but can involve costly repairs if they arise. Overall, with diligent maintenance and attention to emission system warnings, the Sprinter 3500XD is a dependable workhorse for commercial use.
