Summary

The 2010 GMC Sierra 3500 HD is a capable work truck, but owners should be aware of potential issues. The 6.6L Duramax diesel engine, while powerful, can be expensive to maintain due to potential fuel injector, EGR cooler, and turbocharger problems. The gas engines also have their own quirks, such as oil consumption and exhaust manifold bolt issues. Transmission issues can occur with both the Allison and Hydra-Matic transmissions, potentially leading to costly repairs. Suspension and electrical problems are also common complaints. Overall, the severity of these issues ranges from minor inconveniences to major repairs, and the costs can vary significantly depending on the specific problem and the shop performing the work. Pre-purchase inspections are highly recommended.
