Summary Verdict

The 2004 Dodge Sprinter 2500 is a capable workhorse, but potential buyers and current owners should be aware of common issues. The diesel engine, while generally reliable, can experience problems with glow plugs, injectors, and the turbocharger. Transmission issues, particularly with the automatic, can be costly to repair. Suspension components like leaf springs and ball joints are also noted for wear. Electrical gremlins, often related to the BCM or alternator, can arise. Exterior rust is a concern in certain climates. While these issues are documented, many can be mitigated with diligent maintenance and prompt repairs. Overall, the Sprinter 2500 offers good utility, but factor in potential repair costs for these specific components.
