GMC Sierra 2013 Automatic Gasoline mileage: 300 KM or more The vehicle has 360,000 km. It is clean and has no issues. All its maintenance was done at Al-Jomaih agency. The vehicle is clean. Its only problems are the canister and it's not expensive, and it needs an alignment. Its tires are new, two of them are Hankook. The vehicle is good for the user. The canister only affects it when you start it after refueling, you face difficulty. When I have free time, I will fix it. Otherwise, the vehicle is good.
