2013 Chevrolet Silverado 3500

The 2013 Chevrolet Silverado 3500 is a heavy-duty pickup truck known for its towing and hauling capabilities. Engine options include the 6.0L Vortec V8 (360 hp, 380 lb-ft of torque), and the 6.6L Duramax Diesel V8 (397 hp, 765 lb-ft of torque). Both engines are paired with the Allison 1000 6-speed automatic transmission. Owners often praise the Silverado 3500 for its robust engine, comfortable ride (for a heavy-duty truck), and strong towing capacity. Common dislikes include its somewhat dated interior, lower fuel economy, and some reliability concerns with certain components.

Engine

6.0L Vortec V8

• Oil Consumption
  • Description/Symptoms: Excessive oil consumption between oil changes. Some owners have reported needing to add a quart of oil every 1,000 miles or less. Blue smoke may be visible from the exhaust.

Electrical

• Body Control Module (BCM) Issues
  • Description/Symptoms: Intermittent electrical problems such as malfunctioning power windows, door locks, or lights. The BCM may need to be reprogrammed or replaced.
  • Solution: Diagnose the specific BCM fault codes and either reprogram or replace the BCM.

Summary

The 2013 Chevrolet Silverado 3500 can be a reliable workhorse, but potential buyers should be aware of potential issues. The Duramax diesel engine is generally durable but the CP4 fuel pump is a ticking timebomb on these trucks and are very expensive to repair. Electrical problems related to the BCM can also be frustrating. Suspension issues are fairly common given the heavy-duty nature of the truck and the conditions it’s often used in. The cost of repairs can range from a few hundred dollars for suspension components to several thousand for major engine or transmission work. Thorough inspection and maintenance records are crucial when considering a used 2013 Silverado 3500.
