2015 Cadillac XTS

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 XTS.

Body PASSENGER CARTransmission Automatic (S6)

The 2015 Cadillac XTS is a full‑size passenger car built on Cadillac’s rear‑wheel‑drive platform and equipped with a six‑speed automatic (S6) transmission that runs on a 7.0‑quart, 5W‑30 oil capacity engine, delivering EPA ratings of 18 mpg city, 28 mpg highway and a combined 21 mpg. Across the 20132019 model span, owner feedback shows a marked decline in issues, with the 2015 year falling between the early‑generation peak of 103 complaints in 2013 and the low of just five complaints in 2019, and it recorded only 14 total owner complaints and three recalls overall. This positioning indicates that the 2015 XTS benefits from the early reliability improvements introduced after its launch, making it a comparatively stable point in the model’s overall durability record.

Service quick specs OEM factory data

Capacities, torques and tune-up values from the factory service manual.

This engine holds 7.0 qt of 5W-30 engine oil, DOT 3 brake fluid. Torque the oil drain plug to 15.0 ft-lbs. The firing order is 1-2-3-4-5-6. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

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 XTS represents a significant improvement within its generation, with complaints plummeting to just 14 from 103 in 2013 and 49 in 2014, and no crash or fire complaints reported. This year sits at the low point of the complaint trend before a slight uptick in 2016–2017, while its three recalls are fewer than earlier years but not as clean as the zero-recall 2016 and 2017 models. The top complaint areas are vague—led by "Unknown or Other" and powertrain—so the data doesn't specify a root cause for these few issues. Overall, the 2015 model year benefits from early-generation refinements, as evidenced by the steep decline in complaints and a moderate recall count. Provided the three recalls have been addressed, this is a good year to buy, offering a balance of low reported problems and mature engineering.
