2007 Chevrolet Silverado 2500

Introduction:

The 2007 Chevrolet Silverado 2500, a heavy-duty pickup truck, is powered by a variety of engine and transmission options, including a 6.0L V8 with a 6-speed automatic transmission rated at 367 horsepower and 373 lb-ft of torque. It offers a spacious cabin, robust towing and hauling capabilities, and a durable design. However, several prevalent issues have been reported by owners.

Engine

• 6.0L V8
  • Valve Cover Gasket Failure: Leaking oil from the valve covers due to worn-out gaskets. Replacement gaskets and labor cost around $300 - $500+.
  • Manifold Bolt Failure: Broken intake manifold bolts leading to coolant leaks, engine overheating, and loss of power. Repair involves replacing the bolts and damaged components, costing $500 - $1000+.
  • AFM Lifter Failure: Collapsed lifters in the Active Fuel Management (AFM) system causing engine noise, reduced power, and potential catastrophic engine failure. Replacement lifters and labor can cost $2000 - $4000+.
  • Water Pump Failure: Leaking or failing water pump resulting in overheating and loss of coolant. Replacement of the water pump costs $300 - $600+.
  • Ignition Coil Failure: Malfunctioning ignition coils cause misfires, rough idling, and reduced engine performance. Replacing the coil packs costs $200 - $400+.
• Duramax 6.6L Turbo Diesel
  • Injector Failure: Leaking or faulty fuel injectors leading to poor fuel economy, engine noise, and reduced power. Replacing the injectors costs $1000 - $2000 per injector.
  • Turbocharger Failure: Worn-out turbocharger causing reduced boost pressure, power loss, and excessive exhaust smoke. Turbocharger replacement costs $1500 - $3000+.
  • Exhaust Gas Recirculation (EGR) Valve Failure: Sticking or malfunctioning EGR valve resulting in reduced engine performance, increased emissions, and potential engine damage. Cleaning or replacing the EGR valve costs $300 - $600+.
  • Crankshaft Position Sensor Failure: Malfunctioning crankshaft position sensor causing starting issues, engine stalling, and reduced power. Sensor replacement costs $200 - $400+.
  • Fuel Pressure Regulator Failure: Faulty fuel pressure regulator leading to unstable fuel pressure, poor engine performance, and potential fuel leaks. Replacing the regulator costs $200 - $400+.

Transmission

• 6-Speed Automatic (6L90E):
  • Slippage and Shuddering: Transmission slippage or shuddering during gear changes indicating worn-out clutches or torque converter issues. Transmission rebuild or replacement costs $2000 - $4000+.
  • Solenoid Failure: Malfunctioning solenoids affecting shift quality, causing harsh or delayed shifts. Solenoid replacement costs $300 - $600+.
  • Torque Converter Failure: Worn-out torque converter causing slippage, overheating, and loss of power. Torque converter replacement costs $1000 - $2000+.
• Allison 1000 5-Speed (Duramax Option):
  • Pump Failure: Faulty transmission pump leading to low fluid pressure, overheating, and potential transmission failure. Pump replacement costs $1200 - $2000+.
  • Solenoid Pack Failure: Malfunctioning solenoid pack causing shifting issues, delayed engagements, or no engagement. Solenoid pack replacement costs $500 - $1000+.
  • Transfer Case Leak: Leaking transfer case due to worn-out seals or gaskets. Transfer case repair or replacement costs $500 - $1500+.

Suspension

• No Issues Found

Electrical

• Battery Drain: Parasitic battery drain caused by faulty electronics or accessories. Diagnosis and repair vary widely depending on the source of the drain.
• Alternator Failure: Malfunctioning alternator failing to charge the battery, leading to electrical system failure and stalling. Alternator replacement costs $500 - $1000+.
• Starter Failure: Worn-out starter solenoid or motor causing difficulty starting the engine. Starter replacement costs $300 - $600+.
• Body Control Module (BCM) Failure: Malfunctioning BCM affecting various electrical systems, including lights, windows, and locks. BCM replacement costs $600 - $1200+.

Exterior

• Tailgate Lock Failure: Broken tailgate lock or latch mechanism preventing the tailgate from opening or closing properly. Lock or latch replacement costs $200 - $400+.
• Weatherstripping Deterioration: Worn-out or damaged weatherstripping around doors and windows allowing water and wind to enter the cabin. Weatherstripping replacement costs vary depending on the location and extent of damage.

Interior

• Dashboard Cracking: Cracking or warping of the dashboard due to sun exposure or temperature variations. Dashboard replacement costs $600 - $1200+.
• Heater Core Leak: Leaking heater core causing coolant to enter the cabin and fog up the windshield. Heater core replacement costs $500 - $1000+.
• HVAC Blower Motor Failure: Malfunctioning blower motor reducing or eliminating air flow from the heating and cooling system. Blower motor replacement costs $200 - $400+.
• Seat Heater Failure: Faulty seat heater elements or switches preventing the seats from heating properly. Seat heater repair or replacement costs $200 - $500+.

Summary:

The 2007 Chevrolet Silverado 2500 suffers from a range of issues, including significant engine and transmission problems. While some issues are relatively minor and inexpensive to fix, others can be costly and require major repairs. The severity and cost of these issues vary depending on the specific problem, but they can significantly impact the reliability and ownership experience of the vehicle.
