Summary Verdict

The 2010 Chevrolet Avalanche offers a unique blend of utility and comfort, but potential buyers should be aware of common issues. The 5.3L V8 engine is generally robust, but the Active Fuel Management (AFM) system can be a source of problems, leading to misfires and oil consumption. Transmission issues, particularly with the torque converter, are also reported. On the electrical side, the Body Control Module (BCM) and power window motors can be points of failure. Suspension components like ball joints and bushings may require replacement due to wear. While the exterior and interior are generally reliable, specific components like HVAC blend door actuators can fail. Addressing these potential issues proactively can help maintain the Avalanche’s functionality and value.
