Last updated August 4, 2026

About the 2009 GMC Acadia
1st generation (2007-2012), third model year before the 2013 refresh
GMC positions the Acadia as a do-it-all three-row crossover for families who want SUV space and towing ability without the truck-like feel of a traditional full-size SUV. The core appeal is roomy seating in all three rows, flexible cargo space, available AWD, and a smoother, more car-like drive than body-on-frame alternatives. In the GMC lineup, it fills the role of the practical family hauler with a slightly more upscale look and feel than a minivan.
The SLE is the practical family version, with eight seats, flexible second- and third-row seating, and front and rear air conditioning. The more comfort-focused SLT has seven seats with second-row captain’s chairs, leather upholstery, heated front seats, Bluetooth and a 10-speaker Bose audio system.
