2011 GMC Truck Acadia 2WD

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 Acadia 2WD.

Body SUV

The 2011 GMC Acadia 2WD is a mid-size SUV whose powertrain uses 5.5 quarts of 5W-30 engine oil, a routine service spec that anchors its maintenance profile. Within the model's reliability record, this year carries 280 owner complaints with steering as the most-cited problem area and 5 recalls on file, placing it well below the 857-complaint peak set by the 2008 model but still well above the 5-complaint low recorded for 2026. For a researcher, the 2011's middle-ground position makes it a useful reference point for understanding how Acadia quality evolved from its early-production rough patch toward its later, more refined iterations.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2011 GMC Truck Acadia 2WD lead in one area — the steering, 53 of 280 reports (19%), well ahead of the next concern. None of this vehicle's 5 recall campaigns target the steering, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 8 of the reports describe a crash and 10 a fire — a small share of the total, but worth weighing against the steering pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
