Enter your GMC's 17-character VIN to decode its year, model and build details, see US model recall campaigns, and match EPA configurations where available. Set your mileage and fuel price to estimate running costs.
GMC MPG and running costs by model
A quick model-level comparison before you decode. Enter a VIN above for EPA configurations matched to the decoded year and available powertrain details, then adjust your mileage and energy price. These preview figures are broader estimates, not exact year-and-trim ratings.
Annual estimates assume 12,000 miles, US average regular gasoline at $4.35/gal, diesel at $6.20/gal, or residential electricity at $0.17/kWh. Fuel prices dated 2026-10-05. Costs exclude maintenance, insurance, tax and depreciation.
GMC truck prefixes can reflect US or Mexican production. Sierra engines and drivetrains need a full decode before comparing fuel use.
The first three characters form the World Manufacturer Identifier (WMI). These are verified examples, not an exhaustive list. A WMI can cover more than one retail brand; it identifies the manufacturer, not a model, engine or exact assembly plant. Country below refers to the WMI region assignment. Use the full decode for the reported build plant.
This masked example decodes only positions 1–3: 1GT is registered to GENERAL MOTORS LLC, with a United States country assignment. NHTSA lists the vehicle type as truck.
The dots are missing characters, not a complete VIN. They cannot establish an engine, model year, assembly plant or serial number. Enter the full VIN above for those fields where the manufacturer has supplied them.
For US-standard passenger cars, and multipurpose passenger vehicles and trucks rated at 10,000 lb (4,536 kg) or less, a number in position 7 selects 1980–2009; a letter selects 2010–2039. This shortcut does not apply to every overseas-market vehicle, heavy truck or motorcycle. Model year can differ from the calendar year of manufacture. See every year code →
Where to find your GMC VIN
Start with the plate at the base of the windshield, usually on the driver's side, read from outside the car. Look next for the certification label in the front door opening. Compare the full 17 characters with the registration, title or insurance documents. Exact label and stamped-chassis locations vary by model, year and market; the owner's manual is the model-specific authority.
GMC's manual library can be searched by year, make and model. Pick the correct Sierra, Yukon or other model and consult Vehicle Identification; do not infer a truck's engine from its badge alone.

A model campaign is not proof that your individual car is affected or that its repair remains open. Check your VIN with NHTSA or the manufacturer for current applicability and repair status. A VIN decode does not provide accident, mileage or ownership history.
