Summary

The 2005 GMC Savana 3500, while a capable van, is prone to certain issues given its age. Engine problems include oil consumption in the 5.3L, exhaust manifold bolts in the 6.0L, and intake manifold leaks in the 4.3L. Transmission issues like slipping are common with the 4L60E. Suspension components such as ball joints and leaf springs can also wear out. Electrically, fuel pump and instrument cluster failures are seen. The severity of these issues ranges from minor annoyances to potentially costly repairs. Estimated costs range from a few hundred to several thousand dollars, depending on the specific problem and the required repair. Regular maintenance and addressing problems early can help mitigate some of these risks.
