2012 Chevrolet Suburban 2WD

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2012 Suburban 2WD.

The 2012 Chevrolet Suburban 2WD operates with an engine requiring 6 qt of 5W-30 oil viscosity, anchoring its mechanical profile within a model lineage tracked for complaints from 1990 to 2024. Historical data for this range shows a peak of 1004 complaints in 1994 and a low of 37 in 2024, marking the boundaries of the reliability record. Sitting chronologically after the highest recorded issues but prior to the most recent minimum, the 2012 model year occupies the later portion of the recorded history. This placement offers researchers a concrete reference point between the dataset's established extremes.

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.
