Engine

4.8L V8 No Issues Found

5.3L V8

• Excessive Oil Consumption
  • Description/Symptoms: Some 5.3L V8 engines experience excessive oil consumption, often exceeding 1 quart per 1,000 miles. Symptoms include the need to frequently add oil, blue smoke from the exhaust, and a potential decrease in engine performance. This is often linked to the Active Fuel Management (AFM) system.
  • Solution: Potential solutions include replacing the valve cover (revised design), replacing the AFM lifters with non-AFM lifters, or installing an AFM disabler device.
  • Estimated Cost to Fix: $1,500 - $4,000+ (depending on the chosen solution and extent of damage).
  • Recalls: None Found
• Active Fuel Management (AFM) Problems
  • Description/Symptoms: The AFM system, designed to improve fuel economy by deactivating cylinders, can lead to various issues. These include rough idling, misfires, and the aforementioned excessive oil consumption.
  • Solution: As mentioned above, a solution is replacing the valve cover (revised design), replacing the AFM lifters with non-AFM lifters, or installing an AFM disabler device.
  • Estimated Cost to Fix: $200 - $4,000+ (depending on the chosen solution and extent of damage).
  • Recalls: None Found

6.2L V8 No Issues Found

Transmission

6-Speed Automatic (All Engines)

• Torque Converter Shudder
  • Description/Symptoms: Shuddering or vibration felt during light acceleration or at highway speeds. Often most noticeable when the transmission is trying to lock the torque converter.

Summary

The 2012 Chevrolet Tahoe can be a reliable vehicle, but potential buyers should be aware of the common issues, particularly with the 5.3L V8 engine and the transmission. The AFM system’s problems leading to excessive oil consumption can result in significant repair costs. Electrical issues and suspension problems also contribute to potential maintenance expenses. While some repairs are relatively inexpensive, others, such as engine or transmission work, can be costly. A thorough inspection by a qualified mechanic is recommended before purchasing a used 2012 Tahoe to identify potential issues and budget accordingly.
