Frequently Asked Questions
Q: Will performing routine maintenance in my garage void my factory warranty?
A: No, performing your own vehicle maintenance does not void your factory warranty under the Magnuson-Moss Warranty Act.
You must keep clear receipts for all oil, filters, and OEM fluids purchased during maintenance.
Documenting service dates and exact vehicle mileage protects your warranty coverage if components fail later.
Q: What is the mechanical difference between 4WD Auto and 4WD High?
A: 4WD Auto engages front-wheel traction automatically only when rear wheel slippage is detected by speed sensors.
4WD High mechanically locks the transfer case to split torque evenly between front and rear axles continuously.
Use 4WD Auto on dry pavement with patchy ice, but reserve 4WD High for deep snow or dirt off-road trails.
Q: How often should I replace the fuel filter on the 3.0L Duramax diesel engine?
A: Chevrolet recommends replacing the fuel filter every 22,500 miles under normal driving conditions.
If you regularly tow trailers or source diesel fuel in rural locations, replace it every 15,000 miles.
Clean fuel filters prevent high-pressure fuel pump cavitation and protect expensive fuel injectors.
