Known issues on the 2008 Savana 3500. The complaint record for this model year runs to three entries, two on the electrical system and one on the body structure. Neither area is complicated to work on with the right reference: circuit-by-circuit wiring diagrams settle most electrical questions on a van this size, and structural fastener torque values settle the rest. Beyond that, the manual carries the procedures, specifications and diagnostics for the turbocharged 6.6L diesel and the two gasoline V8s across all seven body configurations.
