| Service Item | Interval | Notes |
|---|---|---|
| Engine Oil & Filter | Every 7,500 miles or 12 months (whichever comes first) | Use Dexos-approved full synthetic oil (SAE 0W-20 for gasoline, SAE 15W-40 or 5W-40 for Duramax diesel). Check oil life monitor. |
| Tire Rotation | Every 7,500 miles | Promotes even tire wear and extends tire life. |
| Fuel Filter (Diesel) | Every 22,500 miles or 24 months (Duramax diesel) | Crucial for protecting the high-pressure fuel system from contaminants. |
| Cabin Air Filter | Every 22,500 miles or General Motors' (GM) Oil Life Monitor (OLM) at 24 months | Replace more frequently in dusty environments. |
| Engine Air Filter | Every 45,000 miles | Inspect visually at every oil change, replace if dirty. |
| Brake Fluid | Every 45,000 miles or 3 years | Inspect fluid level and condition at each service. Replace to maintain braking performance. |
| Transfer Case Fluid | Every 97,500 miles or 5 years (whichever comes first) | For 4x4 models. Essential for the longevity of the 4WD system. |
| Automatic Transmission Fluid & Filter | Every 97,500 miles or 5 years (for normal duty) | More frequent replacement (e.g., 45,000 miles or 3 years) for heavy-duty use (towing/hauling frequently). Use DEXRON-VI. |
| Spark Plugs (Gasoline) | Every 97,500 miles | Replace for optimal engine performance and fuel economy. |
| Drive Belt(s) & Hoses | Inspect at every service, replace as needed | Look for cracks, fraying, or signs of wear. |
| Coolant (Engine) | Initial fill for 5 years/150,000 miles, then every 5 years/50,000 miles (Dex-Cool) | Maintains engine temperature and prevents corrosion. |
| Brakes (Pads & Rotors) | Inspect at every service, replace as needed | Varies significantly based on driving style and usage. |
| Frame & Underbody | Annually | Inspect for rust, damage, and loose components, especially in areas using road salt. |

Known Issues and Common Problems for the 2023 Chevrolet Silverado 3500HD (4th Generation: 2020-Present)
While the 2023 Silverado 3500HD is a robust vehicle, like any complex machine, it can have some areas to watch out for. As the 2023 model is relatively new, long-term common issues are still emerging. However, based on the general trends of the 4th generation of Silverado HD trucks, here are some potential areas to monitor:
- Diesel Particulate Filter (DPF) and Regeneration Issues (Duramax Diesel): This is common across many modern diesels. Short trips or excessive idling can prevent the DPF from reaching proper regeneration temperatures, leading to clogging and reduced performance. Regular highway driving is beneficial.
- DEF System (Duramax Diesel): Diesel Exhaust Fluid (DEF) system issues, including sensor failures or clogs, can lead to reduced engine power or prevent the vehicle from starting. Use high-quality DEF and avoid contamination.
- Fuel System Concerns (Duramax Diesel): While less common with the latest generation, previous Duramax engines have had occasional issues with fuel injectors or high-pressure fuel pump (HPFP) failures, often linked to fuel quality. Using reputable fuel sources and maintaining the fuel filter is paramount.
- Electrical Gremlins: Modern trucks are highly computerized. Minor electrical issues, such as infotainment glitches, sensor malfunctions, or accessory problems, can occasionally arise. Keep an eye on dashboard warning lights.
- Brake Wear (Heavy Hauling): While the 3500HD
