overall
Summary
With 2,753 currently listed for sale and an average price of $16,092.00, 33.0% of 2018 GMC Acadias for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 GMC Acadia 4.79 / 5 stars.
61.4% of 2018 Acadia models on CarGurus are accident free.
The 2018 GMC Acadia introduced the option of a powerful V6 engine for more trims, enhancing its versatility for families needing a 3-row crossover vehicle.
Why it stands out
The 2018 GMC Acadia makes a strong case for families seeking a spacious and comfortable interior combined with a robust set of features. Key to its appeal is the availability of a powerful 3.6-liter V6 engine, which significantly boosts performance over the base 2.5-liter engine that some found inadequate. This newfound power is complemented by features that highlight comfort and convenience, such as the standard second-row captain’s chairs that improve access to the third row. Reviewers appreciate the well-equipped base model, which includes modern tech features like a 7-inch touchscreen with Android Auto and Apple CarPlay, while higher trims offer an impressive suite of safety technologies. The Acadia's refined design and improved handling make it easier to maneuver, crucial for daily driving and family outings. However, prospective buyers should note some limitations, such as reduced cargo space compared to competitors and moderate towing capacity.

The stereo system is low budget. Needs more quality , it couldn’t hurt considering the price for the vehicle.

My new/used 2018 Acadia is just what I was looking for. It has mostly all the bells and whistles. I thought it had a heated steering wheel, but I cant locate the button for it. Otherwise the 1 owner who owned it before me took really good care of it and it is very very tight! Nice find for me

Reviewed a 2018 GMC Acadia on Feb 23, 2022
I love my 2018 Acadia. I bought it in 2020 as a CPO vehicle, and it felt and looked brand new. My previous car was an 05 BMW X5 and drove like a sports car. I needed my next SUV to handle the road similarly and it had to be towable. It checked off those boxes easily. I also wanted a 3rd row seat. And the 2nd row seats had to be a bench seat to accommodate my 120lb dog. On top of all that, it had to be reliable!! I LOVE my Acadia and would recommend it to anyone.
