Engine

2.7L Turbo I4

• Piston Cracking/Failure
  • Description/Symptoms: Owners have reported cracked or failed pistons. Symptoms include engine knocking, misfires, reduced power, and potential engine failure. This issue appears to be related to pre-ignition and can be exacerbated by aggressive tuning or high engine loads.
  • Solution: Replacement of the affected pistons, and potentially the entire engine, may be required.
  • Estimated Cost to Fix: $5,000 - $10,000+
  • Recalls: None Found

5.3L EcoTec3 V8

• Active Fuel Management (AFM) Lifter Failure
  • Description/Symptoms: The AFM system, which deactivates cylinders to improve fuel economy, can lead to lifter failure. Symptoms include a ticking or knocking noise from the engine, misfires, and a check engine light.
  • Solution: Replacement of the failed lifters, and potentially the camshaft, is the most common solution. Some owners choose to disable the AFM system to prevent future issues.
  • Estimated Cost to Fix: $3,000 - $6,000+
  • Recalls: None Found

6.2L EcoTec3 V8

• Oil Consumption
  • Description/Symptoms: Some owners have reported excessive oil consumption in the 6.2L V8. This can lead to low oil levels and potential engine damage if not monitored closely.
  • Solution: Possible solutions include replacing the valve cover, PCV valve, or piston rings. In some cases, an engine rebuild or replacement may be necessary.
  • Estimated Cost to Fix: $1,000 - $7,000+ (depending on the cause and severity)
  • Recalls: None Found

Transmission

8-Speed Automatic (8L90)

• Harsh Shifting/Shuddering
  • Description/Symptoms: Many owners have reported harsh shifting, shuddering, and clunking, particularly at low speeds. This issue is often attributed to the transmission’s torque converter clutch (TCC) and valve body.
  • Solution: A transmission flush with an updated fluid (Mobil 1 Synthetic LV ATF HP) can sometimes alleviate the issue. In more severe cases, replacement of the torque converter, valve body, or the entire transmission may be necessary. Some owners have also reported success with a software reflash.
  • Estimated Cost to Fix: $300 (flush) to $4,000+ (transmission replacement)
  • Recalls: None Found

10-Speed Automatic (10L80)

• Rough Shifting
  • Description/Symptoms: Some owners have reported rough or erratic shifting, particularly when shifting between gears at low speeds.
  • Solution: A software update or transmission fluid flush can sometimes resolve the issue. In more severe cases, valve body replacement may be required.
  • Estimated Cost to Fix: $300 (flush) to $1,500+ (valve body replacement)
  • Recalls: None Found

Suspension

• Shocks Leaking
  • Description/Symptoms: Premature failure of the shock absorbers causing leaking fluid. Causes poor ride quality and handling.
  • Solution: Replacement of failed shocks
