Engine

6.6L Duramax Diesel V8 (LMM)

• Fuel Injector Failure

  • Estimated Cost to Fix: $4,000 - $8,000+
  • Recalls: None Found

6.0L Vortec V8

• Oil Consumption
  • Description/Symptoms: Excessive oil consumption without visible leaks. May lead to fouled spark plugs and catalytic converter issues.
  • Solution: In some cases, a PCV valve replacement can resolve the issue. In more severe cases, piston ring replacement may be necessary.
  • Estimated Cost to Fix: PCV valve replacement $50-$150; Piston ring replacement $2,000 - $4,000+

Summary

The 2010 Chevrolet Silverado 3500HD, while a capable truck, has its share of potential issues. The most concerning, and potentially expensive, relate to the Duramax diesel engine, particularly fuel injector and CP4 pump failure. Transmission problems with the 6L90, especially TCC failure, are also common. Electrical gremlins related to the instrument cluster and BCM can be frustrating to diagnose and repair. While some issues like suspension wear and seat heater failures are relatively minor, addressing major engine or transmission problems can be quite costly. Potential buyers should be aware of these potential issues and carefully inspect any used 2010 Silverado 3500HD before purchase.
