    Certified Pre-Owned: the 2023 GMC Sierra AT4

    No 2023 GMC Sierra AT4 is for sale by CarmaCars at the moment; this page helps you judge the car before you buy one elsewhere. Here is what to know about the 2023 GMC Sierra AT4 before buying one.

    Before you sign for the Sierra

    NHTSA lists 4 recall campaigns for this model; ask the seller for proof each one was fixed. A pre-purchase inspection at a shop you choose is money well spent. In Ontario, a used car needs a Safety Standards Certificate to be registered. Ask for the service records and check open recalls by the VIN.

    Engine and fuel

    Power comes from the 3.0L 6-cylinder turbo, driving through a 10-speed automatic. It runs on diesel, sold at most highway stations. Rear-wheel drive gives balanced handling; in winter, the tires make the biggest difference.

    Its combined rating is 9.1 L/100 km, which means roughly 27 litres for 300 km. In money, 1,000 km costs about $141.10 at our price setting. EPA puts its fuel cost at US$3,700 a year for 15,000 miles at US prices.

    Good uses for the Sierra

    It suits a stretch between cars, by the week or the month. It suits moving day, renovation runs and anything that needs an open bed.

    Room inside

    Being a pickup truck, it trades parking ease for a cargo bed.

    A longer test drive

    If the Sierra is in our fleet, its page shows the rates; if not, a similar car helps you judge. Rent the Sierra for a week, or up to 365 days, before you commit to buying one. Nothing is charged until we confirm the rental and you approve the offer.

    Which one to look for

    If you are unsure between two options, rent one of them for a week first. Set a budget that includes tax, licensing, insurance and the first set of tires. Compare the AT4 with the other trims of the same year before you decide.

    What it costs to run

    Tires, brakes and batteries are the regular costs to budget for beyond fuel. Ask what a set of tires costs for this trim; sizes and prices vary. At our price setting, 100 km costs about $14.11 in fuel.
