Engine

6.0L Vortec V8 Gasoline

• Excessive Oil Consumption
  • Description/Symptoms: Some owners report higher-than-normal oil consumption, requiring frequent topping off between oil changes. This may manifest as blue smoke from the exhaust or a noticeable drop in oil level on the dipstick.
  • Solution: A thorough inspection of the engine is needed to identify the cause. Possible issues include worn piston rings, leaking valve seals, or issues with the PCV system. Repair will involve replacing the affected components.
  • Estimated Cost to Fix: $1,000 - $5,000+ (depending on the root cause and extent of the damage)
  • Recalls: None Found
• Catalytic Converter Failure
  • Description/Symptoms: Premature failure of the catalytic converter, leading to a check engine light and potential reduction in engine performance.
  • Solution: Replacement of the faulty catalytic converter.
  • Estimated Cost to Fix: $800 - $1,500+
  • Recalls: None Found

5.2L 4HK1-TC Diesel

• Diesel Particulate Filter (DPF) Issues
  • Description/Symptoms: Frequent DPF regeneration cycles or DPF clogging, leading to reduced engine performance, increased fuel consumption, and a check engine light.
  • Solution: Diagnose the root cause of the DPF issues. This may involve forced regeneration, cleaning the DPF, or replacing faulty sensors related to the exhaust aftertreatment system. In some cases, the DPF may need to be replaced.
  • Estimated Cost to Fix: $500 - $3,000+ (depending on the solution)
  • Recalls: None Found
• EGR Valve Problems
  • Description/Symptoms: Malfunctioning EGR (Exhaust Gas Recirculation) valve, causing rough idling, poor acceleration, and a check engine light.
  • Solution: Replacement of the EGR valve.
  • Estimated Cost to Fix: $300 - $800+
  • Recalls: None Found

Transmission

• Aisin A460 Transmission

• Harsh Shifting
  • Description/Symptoms: Reports of harsh or jerky shifting, particularly between certain gears. This can be more pronounced when the transmission is cold.
  • Solution: Check the transmission fluid level and condition. A fluid flush and filter change might resolve the issue. If the problem persists, further diagnosis may be needed to check for valve body issues or other internal problems.
  • Estimated Cost to Fix: $200 - $3,000+ (depending on severity and required repairs)
  • Recalls: None Found
• Torque Converter Shudder
  • Description/Symptoms: A shuddering or vibration felt during acceleration or when the torque converter is locking up.
  • Solution: In some cases, a transmission fluid flush with a specific fluid formulation can alleviate the shudder. If the problem persists, the torque converter may need to be replaced.
  • Estimated Cost to Fix: $300 - $2,000+
  • Recalls: None Found

Suspension

• Leaf Spring Sagging
  • Description/Symptoms: Premature sagging of the rear leaf springs, particularly when carrying heavy loads. This can lead to a reduced ride height and compromised handling.
  • Solution: Replacement of the rear leaf springs with heavier-duty units.
  • Estimated Cost to Fix: $500 - $1,500+
  • Recalls: None Found

Electrical

• Sensor Failures
  • Description/Symptoms: Various sensor failures (e.g., ABS sensors, wheel speed sensors, etc.) leading to warning lights on the dashboard and potential issues with the affected systems.
  • Solution: Identify and replace the faulty sensor.
  • Estimated Cost to Fix: $100 - $500+ per sensor (depending on the type of sensor and labor costs)
  • Recalls: None Found
• Wiring Harness Issues
  • Description/Symptoms: Corrosion or damage to wiring harnesses, leading to intermittent electrical problems.
  • Solution: Repair or replacement of the affected wiring harness sections.
  • Estimated Cost to Fix: $200 - $1,000+ (depending on the severity and location of the damage)
