Thinking of buying the 2021 GMC Sierra SLE?
CarmaCars rents cars and does not sell the 2021 GMC Sierra SLE; this page helps you judge it before you buy one elsewhere. This page sets out the 2021 GMC Sierra SLE for buyers, in plain words.
A buyer's checks
Owners filed 666 complaints with NHTSA, most often about engine, power train and electrical system; have those parts checked. Look at the tires, brakes and battery; they are costly to replace. A pre-purchase inspection at a shop you choose is money well spent. NHTSA lists 10 recall campaigns for this model; ask the seller for proof each one was fixed.
What the figures tell you
Its powertrain is the 3.0L 6-cylinder turbo with rear-wheel drive. It runs on diesel, sold at most highway stations. Rear-wheel drive gives balanced handling; in winter, the tires make the biggest difference.
The EPA rates it at 9.1 L/100 km combined, so a 300 km weekend uses about 27 litres. Every 100 km costs about $14.11 in fuel at our price setting. At US fuel prices, the EPA estimates US$3,700 a year for 15,000 miles.
Who the Sierra suits
It suits people curious about the model who want to drive it before they buy. It suits anyone who needs a car for a few days, a week or a month without buying one.
Size and space
It is built for loads that would never fit in a trunk.
Drive it on your own roads
Load it with your things and park it where you park; then decide. Rent it, live with it for a week, and decide with real experience. A week of your own driving tells you more than a test drive: the commute, the parking, the fuel.
Picking a year and a trim
Look at a few listings of the same year and trim to get a feel for fair prices. A newer year is not always better; check what changed before paying more for it. If you are unsure between two options, rent one of them for a week first.
Money matters
Ask what a set of tires costs for this trim; sizes and prices vary. The EPA estimates US$3,700 a year in fuel for 15,000 miles at US prices. At our price setting, 100 km costs about $14.11 in fuel.
