2010 Cadillac STS

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2010 STS.

Body PASSENGER CAR

The 2010 Cadillac STS, a passenger car built on Cadillac’s rear‑wheel‑drive platform, is equipped with a 6‑quart oil capacity and requires 5W‑30 API‑rated oil, underscoring its relatively low maintenance demands. In its own model‑year cohort, the STS attracted only four owner complaints—none involving recalls—and the most frequent issue was fuel/propulsion, a common theme across the brand’s lineup. Within the broader 1998‑2011 complaint window, the 2010 model sits comfortably between the all‑time low of three complaints in 1998 and the peak of 141 complaints in 2006, indicating a modestly reliable period in the STS’s service history.

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.

The 2010 model year represents the nadir of complaint activity within this generation, logging only four complaints compared to fifteen in 2009 and seven in 2011, while maintaining zero recalls and investigations. Following the turbulent 2005-2006 period that saw 101-141 complaints and multiple recalls annually, the series demonstrates a consistent downward trend in reported issues, with 2010 marking the lowest point in the federal dataset. The minimal 2010 complaints are distributed across four separate systems—fuel/propulsion, electrical/structure, stability control, and exterior lighting—with single instances each, and the data records zero crash or fire incidents. Given its position at the bottom of the reliability arc and absence of safety campaigns, the 2010 STS stands as the most favorable model year in this generation for a used purchase.
