Common dislikes include its size (making it difficult to maneuver in tight spaces) and relatively poor fuel economy.

Engine

5.3L V8 (L83)

• Active Fuel Management (AFM) Lifter Failure
  • Description/Symptoms: Engine misfires, rough running, check engine light illumination. Can lead to camshaft damage if not addressed promptly. Often occurs at higher mileage.
  • Solution: Replace faulty lifters, potentially including the camshaft if damaged. Some owners opt to delete the AFM system altogether with aftermarket parts and tuning.
  • Estimated Cost to Fix: $2,500 - $5,000+ depending on the extent of damage and whether AFM is deleted.
  • Recalls: None Found
• Excessive Oil Consumption
  • Description/Symptoms: Noticeable decrease in oil level between oil changes, blue smoke from the exhaust (especially upon startup), and potential for engine damage if oil levels are not maintained.
  • Solution: Some owners have had success with replacing the PCV valve or installing an oil catch can. In more severe cases, piston ring replacement may be necessary.
  • Estimated Cost to Fix: $100 (PCV Valve), $150 - $300 (Oil Catch Can), $3,000 - $6,000+ (Piston Rings)
  • Recalls: None Found

6.2L V8 (L86)

• Active Fuel Management (AFM) Lifter Failure
  • Description/Symptoms: Identical to the 5.3L V8 AFM lifter failure, with engine misfires, rough running, and potential camshaft damage.
  • Solution: Similar to the 5.3L, replace faulty lifters, potentially including the camshaft. AFM delete is also an option.
  • Estimated Cost to Fix: $2,500 - $5,000+ depending on the extent of damage and whether AFM is deleted.
  • Recalls: None Found
• Carbon Buildup on Intake Valves (Direct Injection)

  • Recalls: None Found

Electrical

• Battery Drain
  • Description/Symptoms: Battery draining overnight or within a short period, requiring frequent jump starts.

Summary

The 2017 Chevrolet Suburban has some notable issues, particularly concerning the engine’s Active Fuel Management system and the 8-speed transmission’s shifting performance. The AFM lifter failures can be quite costly to repair and can lead to more extensive engine damage if ignored. The 8-speed transmission issues, while often addressed with a fluid flush, can sometimes require more significant repairs. Electrical problems and suspension issues (if equipped with MRC or air suspension) add to the potential repair costs. Overall, while the Suburban offers a lot of utility, potential buyers should be aware of these common issues and factor in potential repair costs when considering a purchase.
