The fourth-generation Chevrolet Silverado, introduced in 2019 and still in-production, has been one of the best-selling trucks in the country, and it’s easy to see why. With updated powertrains, advanced tech features, and a lighter body, the 4th Generation Chevrolet Silverado is a big improvement over older models. Despite these improvements, owners and mechanics have identified a number of common issues on the Chevrolet Silverado 4th Generation. Below are some of the biggest issues, along with symptoms to look out for and our recommended fixes.
Transmission Problems
Symptoms
- Harsh or delayed shifts, especially at lower speeds or when towing
- Noticeable vibration at highway speeds
- Clunking noise when shifting from Park to Drive or Reverse
Possible Causes & Fixes
- Torque Converter or Transmission Tuning: Some 8-speed and 10-speed transmissions can suffer from software calibration issues or torque converter shudder. A firmware update can often smooth out shifts. In cases of severe shudder, the torque converter or transmission fluid may require replacement.
- Driveline Imbalance: Unbalanced driveshafts, worn U-joints, or tire/wheel issues can cause vibrations at highway speeds. This can be helped by balancing/rotating tires, and inspect driveline components for wear.
- Mounts & Suspension Alignment: Loose engine or transmission mounts, as well as misaligned suspension, can amplify vibrations. Have these mounts inspected and re-torque suspension components to factory specs. Perform an alignment to fix any suspension geometry issues.
Engine Lifter Problems
Symptoms
- Ticking or tapping noises from the engine
- Rough idling or misfires, especially under light throttle
- Check-engine light with codes related to cylinder misfires
Possible Causes & Fixes
- Valve Lifter Failures: Trucks equipped with Dynamic Fuel Management (DFM) can experience lifter collapse or sticking. This system is known to sensitive to the type of oil used, so make sure to follow the recommended oil change intervals using the correct synthetic oil.
Engine Oil Consumption & Leaks
Symptoms
- Drips or puddles under the truck or a burning oil smell
- Low oil readings on the dipstick
Possible Causes & Fixes
- Piston Ring Issues Issues: Excess oil consumption can be linked to worn piston rings, especially with higher-mileage engines. Keep up with oil changes and monitor oil levels frequently. If consumption is severe, consider having your engine inspected and tested for compression.
- Valve Cover & Oil Pan Gaskets: Over time, gaskets can shrink or degrade, causing leaks. Regular inspections (especially with high-mileage trucks) help catch leaks early.
Diesel-Specific Issues (3.0L Duramax)
Symptoms
- Hard starting, rough idling, or reduced power
- Excessive black exhaust smoke
- Fuel-related error messages or check-engine lights
Possible Causes & Fixes
- DPF & EGR Clogging: Frequent short trips or idling can lead to clogged emissions components. Make sure your truck reaches full operating temperature regularly, allowing the DPF system to clear. For repeated issues, we suggest inspecting the EGR system.
- Fuel System Wear: Some Duramax owners have reported issues with the fuel pump failing or cutting out. Be sure to follow the fuel filter replacement intervals. Monitor for signs of unusual fuel pump noise or stalling.
4th-Gen Chevrolet Silverado Maintenance
If you own a Chevrolet Silverado, you should make sure to regularly service and maintain your truck. By following the Chevrolet Silverado maintenance schedule, you can minimize or even prevent some of these common issues on the Chevrolet Silverado, or at the very least be informed of them before they become major repairs.
- Follow Service Intervals: Stick to GM’s recommended service schedules for engine oil, transmission fluid, and fuel filters (diesel). Frequent towing or off-roading may require more frequent changes.
- Inspect Suspension & Steering: Ensure alignment and tire balancing are maintained. Check shocks, ball joints, and tie rods for wear, especially if you drive on rough roads.
- Use the Proper Oil & Fuel: For gas engines, follow the specified oil grade and fuel type. For diesel, use high-quality fluids and keep the DEF tank filled if applicable.
- Stick to Towing Limits: Exceeding the payload or towing capacities can greatly accelerate driveline wear. Utilize trailer brake controllers and safe towing practices to reduce stress on the truck.
