    The 2021 GMC Sierra AT4 for buyers

    We are a rental company, not a dealer, so there is no 2021 GMC Sierra AT4 for sale by us right now. Before buying the 2021 GMC Sierra AT4, read what the figures say and how to try one first.

    Recalls and complaints

    Owners filed 666 complaints with NHTSA, most often about engine, power train and electrical system; have those parts checked. Have a mechanic inspect a used one before you buy it. Look at the tires, brakes and battery; they are costly to replace. In Ontario, a used car needs a Safety Standards Certificate to be registered.

    The numbers in plain words

    The 3.0L 6-cylinder turbo is what moves it, with four-wheel drive. It runs on diesel, sold at most highway stations. Four-wheel drive helps on rough ground and deep snow; on dry roads it behaves like any other vehicle.

    At 9.9 L/100 km combined, a 300 km drive takes roughly 30 litres of fuel. In money, 1,000 km costs about $153.50 at our price setting. At US fuel prices, the EPA estimates US$4,000 a year for 15,000 miles.

    Best uses

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

    What the Sierra is like

    As a pickup truck, it has an open bed for things that would never fit in a trunk.

    Try before you buy

    A test week in the Sierra tells you more than any review. Try the Sierra on your commute, then decide. Load it with your things and park it where you park; then decide.

    Year and trim

    Compare the AT4 with the other trims of the same year before you decide. Write down the VIN of any car you consider; it unlocks the recall and service history. Decide what matters most first: fuel use, space, or the price you can pay.

    Money matters

    Ask what a set of tires costs for this trim; sizes and prices vary. The EPA estimates US$4,000 a year in fuel for 15,000 miles at US prices. At our price setting, 100 km costs about $15.35 in fuel.
