Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 60,000 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.

The 2015 Cadillac ATS sits at an inflection point in its generation's federal record, with complaints falling sharply from 160 in the 2013 launch year and 102 in 2014 to just 28 for the target year. Recall activity also moderated, with 4 campaigns in 2015 (down from 6 in 2013) and continuing to taper to zero by 2019, while NHTSA investigations remained absent across every model year in the dataset, indicating no major safety escalations were warranted. The 2015's top complaint areas are notably diffuse — Exterior Lighting, Power Train, and Steering each tallying only 3 complaints, with a combined Steering/Electrical category at 2 — pointing to no single concentrated failure mode. Against this backdrop, the single crash complaint and zero fire complaints in 2015 reinforce a relatively benign safety profile, though the data does not specify root causes for these categories. Technical Service Bulletins follow a declining arc from 2,402 in 2013 to 1,776 in 2015, a pattern consistent with the manufacturer resolving early issues rather than introducing new ones, while complaint counts after 2015 stay modest (peaking at 35 in 2016) before tapering to just 2 by 2019. Taken together, the 2015 is a defensible year to consider on the used market: it post-dates the steepest teething problems of the launch years while remaining early enough in the generation to benefit from those refinements, making it a strong candidate within this ATS run — provided a pre-purchase inspection verifies the specific Lighting, Power Train, and Steering items raised by prior owners.
