Engine

5.2L Duramax Diesel

• Diesel Particulate Filter (DPF) Issues
  • Description/Symptoms: The DPF becomes clogged prematurely, leading to reduced engine performance, frequent regeneration cycles, and eventual engine shutdown. Warning lights such as the “Check Engine” or “DPF Full” illuminate on the dashboard.
  • Solution: Replacement of the DPF filter or forced regeneration by a certified technician. Addressing the underlying cause of excessive soot production (e.g., faulty injectors, EGR valve issues) is crucial to prevent recurrence.
  • Estimated Cost to Fix: $1,500 - $3,500+
  • Recalls: None Found
• EGR Valve Failure
  • Description/Symptoms: Malfunctioning Exhaust Gas Recirculation (EGR) valve leading to rough idling, reduced power, increased emissions, and the “Check Engine” light illumination.
  • Solution: Replacement of the EGR valve. Cleaning the EGR cooler may also be necessary.
  • Estimated Cost to Fix: $500 - $1,500+
  • Recalls: None Found
• Fuel Injector Problems
  • Description/Symptoms: Faulty fuel injectors causing poor fuel economy, rough running, misfires, and difficulty starting.
  • Solution: Diagnosis and replacement of the faulty fuel injectors.
  • Estimated Cost to Fix: $500 - $3,000+ (depending on the number of injectors replaced)
  • Recalls: None Found

Transmission

Aisin Automatic Transmission (Specific Model Unspecified due to variance)

• Shifting Problems
  • Description/Symptoms: Hard or erratic shifting, delayed engagement, slipping, or failure to shift into certain gears.
  • Solution: Diagnosis by a transmission specialist to identify the root cause, which could be valve body issues, solenoid failures, or internal component wear. Repair or replacement of the affected components.
  • Estimated Cost to Fix: $500 - $4,000+ (depending on the severity and required repairs)
  • Recalls: None Found

Suspension

• Leaf Spring Issues
  • Description/Symptoms: Premature sagging or breakage of leaf springs, resulting in reduced load-carrying capacity, poor ride quality, and potential safety hazards.
  • Solution: Replacement of the damaged leaf springs with upgraded or heavy-duty options. Inspection and replacement of related components such as shackles and bushings.
  • Estimated Cost to Fix: $500 - $2,000+ (depending on the extent of the damage and type of replacement springs)
  • Recalls: None Found

Electrical

• Wiring Harness Issues
  • Description/Symptoms: Corrosion or damage to wiring harnesses, especially in areas exposed to the elements, leading to electrical shorts, sensor malfunctions, and intermittent electrical problems.
  • Solution: Repair or replacement of the damaged wiring harness sections. Proper routing and protection of the wiring harnesses to prevent future issues.
  • Estimated Cost to Fix: $200 - $1,500+ (depending on the extent of the damage and labor involved)
  • Recalls: None Found
• Sensor Failures
  • Description/Symptoms: Various sensor failures (e.g., wheel speed sensors, ABS sensors, coolant temperature sensors) resulting in warning lights, system malfunctions, and reduced performance.
  • Solution: Diagnosis and replacement of the faulty sensors.
  • Estimated Cost to Fix: $100 - $500+ per sensor
  • Recalls: None Found

Exterior

• Rust
  • Description/Symptoms: Rust forming in areas exposed to salt and moisture, especially around the seams, and undercarriage.
  • Solution: Rust repair by cutting out the rust and welding in new plates, followed by body filler, primer, and paint.
  • Estimated Cost to Fix: $200 - $2,000+ (depending on the extent of the damage)
  • Recalls: None Found

Interior

• HVAC Issues
  • Description/Symptoms: Malfunctioning heating and air conditioning systems, including blower motor failure, blend door actuator problems, and refrigerant leaks.
  • Solution: Diagnosis and repair or replacement of the faulty components, such as the blower motor, blend door actuator, or condenser.
  • Estimated Cost to Fix: $200 - $1,000+
  • Recalls: None Found

Summary
