Common dislikes include its large size making it difficult to maneuver in tight spaces, and high fuel consumption.

Engine

5.3L EcoTec3 V8

• Active Fuel Management (AFM)/Dynamic Fuel Management (DFM) Lifter Failure
  • Description/Symptoms: Engine misfires, rough idling, check engine light. Often occurs at relatively low mileage. The AFM/DFM system deactivates cylinders to improve fuel economy, but the lifters in this system are prone to failure.
  • Solution: Replace the failed lifters and potentially the camshaft if damaged. Some owners choose to disable the AFM/DFM system altogether with aftermarket tuning to prevent future failures.
  • Estimated Cost to Fix: $2,500 - $4,000+ (depending on damage and shop rates)
  • Recalls: None Found
• Oil Consumption
  • Description/Symptoms: Excessive oil consumption requiring frequent top-offs between oil changes. May be related to the AFM/DFM system or faulty valve seals.
  • Solution: Diagnosis is crucial to determine the root cause. Options range from replacing valve seals to addressing AFM/DFM issues.
  • Estimated Cost to Fix: $500 - $3,000+ (depending on the issue and repair needed)
  • Recalls: None Found

6.2L EcoTec3 V8

• Active Fuel Management (AFM)/Dynamic Fuel Management (DFM) Lifter Failure
  • Description/Symptoms: Similar to the 5.3L, engine misfires, rough idling, check engine light.
  • Solution: Replace failed lifters and potentially the camshaft. Consider AFM/DFM disablement.
  • Estimated Cost to Fix: $2,500 - $4,000+ (depending on damage and shop rates)
  • Recalls: None Found
• Oil Consumption
  • Description/Symptoms: Excessive oil consumption requiring frequent top-offs between oil changes.
  • Solution: Diagnosis is crucial to determine the root cause. Options range from replacing valve seals to addressing AFM/DFM issues.
  • Estimated Cost to Fix: $500 - $3,000+ (depending on the issue and repair needed)
  • Recalls: None Found

3.0L Duramax Turbo-Diesel

• High Pressure Fuel Pump (HPFP) Failure
  • Description/Symptoms: Engine stalls, loss of power, hard starting, check engine light. Potential for metal contamination in the fuel system.
  • Solution: Replace the HPFP. Thoroughly flush the entire fuel system to remove any metal debris.
  • Estimated Cost to Fix: $3,000 - $7,000+ (depending on the extent of contamination)
  • Recalls: None Found

Transmission

10-Speed Automatic Transmission (All Engines)

• Rough Shifting/Hard Shifts
  • Description/Symptoms: Harsh or jerky shifts, especially between certain gears. Hesitation or delays when shifting.
  • Solution: Software reflash/update of the transmission control module (TCM). In some cases, valve body replacement may be necessary.
  • Estimated Cost to Fix: $150 (reflash) - $1,500+ (valve body)
  • Recalls: None Found
• Transmission Slipping
  • Description/Symptoms: The engine revs high without the vehicle accelerating properly, or the transmission may hesitate to engage a gear. This can also present with clunking or grinding sounds.
  • Solution: A software reflash is required, but some cases may require the entire transmission to be replaced.
  • Estimated Cost to Fix: $150 (reflash) - $4,000+ (transmission replacement)
  • Recalls: None Found

Suspension

• Air Ride Suspension Issues (If Equipped)
  • Description/Symptoms: The air suspension fails to maintain proper ride height, the vehicle sags or is uneven, the compressor is noisy or doesn’t function.
  • Solution: Diagnosing the leak is critical. Components that are often replaced are airbags and air compressor.
  • Estimated Cost to Fix: $500 - $2,000+ (depending on the failed component)
  • Recalls: None Found

Electrical

• Infotainment System Glitches
  • Description/Symptoms: Freezing, lagging, screen blackouts, connectivity issues with Apple CarPlay or Android Auto.
  • Solution: Software updates or replacement of the infotainment screen.
  • Estimated Cost to Fix: $0 (software update) - $1,200+ (screen replacement)
  • Recalls: None Found
• Battery Drain
  • Description/Symptoms: The battery is dead, or you must jump start the vehicle. The car dies quickly after sitting for only a few days.
  • Solution: Replace the battery.
