The second-generation GMC Acadia marks a change in philosophy compared to its predecessor: it was shortened and lightened to become a more agile midsize SUV, while retaining 3 rows of seats. Sharing its platform (C1XX) with the Chevrolet Traverse and Cadillac XT5, it offers a comfortable and well-finished cabin. A facelift occurred in 2020, introducing a new 2.0L Turbo engine, a 9-speed automatic gearbox, and aesthetic tweaks. Overall, it is a solid family vehicle, whose reliability depends heavily on the chosen engine.
The second-generation GMC Acadia is a competent family SUV, but its reliability record is highly mixed depending on the engine. The obvious choice is the 3.6L V6 (LGX), which proves to be very robust, powerful, and perfectly suited to the vehicle's size. On the other hand, the 2.5L 4-cylinder engine is to be avoided due to its recurring head gasket issues and lack of breath. When buying a used model, favor an AWD V6, ensure the transfer case has had its oil changed, and verify that the automatic gearbox updates (especially on the 2017-2018 model years) as well as the numerous manufacturer recalls have been performed.
