Engine

6.6L Duramax V8

• Head Gasket Failure: Blown head gaskets can cause coolant leaks, white smoke from the exhaust, and overheating. Replacement of the head gaskets is necessary, along with any damaged components. Cost: $1,500 - $3,000+
• Injector Failure: Faulty fuel injectors can lead to engine misfires, rough idling, and decreased power. Replacement of the injectors is required. Cost: $500 - $1,200+ per injector
• Turbocharger Failure: The turbocharger can fail due to bearing failure or oil starvation. Symptoms include reduced power, black smoke from the exhaust, and a whistling or grinding noise. Turbocharger replacement is necessary. Cost: $1,200 - $2,500+

7.8L Vortec V8

• Valve Seat Recession: Worn valve seats can cause loss of compression, misfires, and poor engine performance. Replacement of the valve seats is necessary. Cost: $1,000 - $2,000+

8.1L Vortec V8

• Transmission Cooler Lines: Leaking transmission cooler lines can cause transmission fluid loss and overheating. Replacement of the lines is necessary. Cost: $300 - $700+
• Plenum Gasket Failure: A leaky plenum gasket can cause vacuum leaks, resulting in rough idling and poor engine performance. Replacement of the gasket is necessary. Cost: $200 - $500+

Transmission

6-Speed Allison Automatic

• Torque Converter Failure: A faulty torque converter can cause shuddering, slipping, or loss of power. Replacement of the torque converter is necessary. Cost: $1,000 - $2,000+
• Valve Body Failure: A malfunctioning valve body can affect gear selection, resulting in delayed or erratic shifting. Replacement of the valve body is required. Cost: $500 - $1,200+
• Transmission Control Module (TCM) Failure: A faulty TCM can cause transmission problems such as shifting issues, limp mode, or complete transmission failure. Replacement of the TCM is necessary. Cost: $400 - $800+

Suspension

• Leaf Spring Breakage: Heavy loads can cause the leaf springs to break, resulting in a sagging rear end. Replacement of the leaf springs is necessary. Cost: $600 - $1,200+ per side
• Shock Absorber Failure: Worn shock absorbers can affect ride quality and handling. Replacement of the shock absorbers is necessary. Cost: $200 - $400+ per axle

Electrical

• Headlight Switch Failure: A faulty headlight switch can cause intermittent or complete headlight failure. Replacement of the switch is necessary. Cost: $100 - $250+
• Alternator Failure: A malfunctioning alternator can cause battery drain or failure to charge. Replacement of the alternator is necessary. Cost: $400 - $800+

Exterior

• Rust: The undercarriage and body panels are susceptible to rust, especially in harsh climates. Regular inspection and maintenance are recommended to prevent major corrosion issues.

Interior

• HVAC System Failure: The heating, ventilation, and air conditioning (HVAC) system can develop issues such as weak airflow, temperature control problems, or complete failure. Repair or replacement of the affected components is necessary. Cost: $500 - $1,500+
• Cruise Control Failure: The cruise control system can malfunction due to faulty switches or wiring issues. Repair or replacement of the affected components is necessary. Cost: $200 - $600+

Summary

The 2007 Chevrolet W4500 Tiltmaster is a durable and reliable workhorse, but it has some known issues that can be costly to repair. Head gasket failure, injector failure, and valve seat recession are the most common engine issues. Transmission problems can include torque converter failure, valve body failure, and TCM failure. The suspension and electrical systems can also encounter problems. While the interior issues are generally less severe, they can still affect the comfort and convenience of the vehicle.
