Thinking of buying the 2025 GMC Sierra AT4?

CarmaCars rents cars and does not sell the 2025 GMC Sierra AT4; this page helps you judge it before you buy one elsewhere. Buying the 2025 GMC Sierra AT4 is a big decision; here is the information we have.

What to check on the Sierra

NHTSA lists 4 recall campaigns for this model; ask the seller for proof each one was fixed. NHTSA has 176 owner complaints on file, mostly about engine, power train and electrical system. 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.

Specs, explained

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.

For 300 km of mixed driving, expect about 28 litres, from its 9.2 L/100 km rating. For 1,000 km, budget about $142.60 at our price setting. At US fuel prices, the EPA estimates US$3,700 a year for 15,000 miles.

Who rents the Sierra

It suits someone whose own car is in the shop for a while. It suits a stretch between cars, by the week or the month.

Space and size

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

Drive it on your own roads

Drive the Sierra on your commute before you commit to it. Rent the Sierra for a week, or up to 365 days, before you commit to buying one. If the Sierra is in our fleet, its page shows the rates; if not, a similar car helps you judge.

Choosing the right one

If two trims share a powertrain, the difference is equipment, which you can check in person. 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.

The cost of driving it

Ask what a set of tires costs for this trim; sizes and prices vary. At our price setting, 100 km costs about $14.26 in fuel. The EPA estimates US$3,700 a year in fuel for 15,000 miles at US prices.
