2018 GMC Acadia Review

from the expert editorial team

What it is: The GMC Acadia started life as a large crossover SUV, but as part of a dramatic redesign for 2017, it dropped 700 pounds and shrunk in all key dimensions to mid-size proportions. A 2.5-liter four-cylinder engine is standard and a 3.6-liter V-6 is optional. Both team with a six-speed automatic transmission and are available with front- or all-wheel drive.

Competitors include the Ford Explorer, Honda Pilot, Hyundai Santa Fe, Nissan Pathfinder and Toyota Highlander.

New for 2018

A tire-fill alert that monitors how much air is pumped into an underinflated tire is standard on all models. The Denali version gains an automatic heated steering wheel, and the All Terrain version is available with five, six or seven seats. Last year, it came only with seating for five.

Not reliable

by JG on June 24, 2020

This car has broken twice with under 36,000 miles on it. GMC parts are always backordered for weeks. I currently can’t drive my car safely and am waiting weeks on the part. Will not ever buy GMC again... Read full review


Stylish & Smooth Drive

by Girl Mom from Ozarks, Missouri on April 13, 2020

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
