Factory maintenance schedule OEM · verified
Normal service, condensed from the factory interval matrix.
Under the factory schedule, replace the spark plugs every 97,500 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.
Every 7,500 mi

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 2020 GMC Truck Acadia top in one area — the power train, 9 of 97 reports (9%), well ahead of the next concern. None of this vehicle's 6 recall campaigns target the power train, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 4 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the power train 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.
