2009 Cadillac CTS

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 CTS.

Body PASSENGER CARTransmission Automatic (S6)

The 2009 Cadillac CTS is a four‑door luxury sedan built on the GM Alpha platform, powered by a V6 engine that requires 6 quarts of 5W‑30 API‑approved oil and pairs with an S6 automatic transmission; its EPA rating of 17 city/26 highway/20 combined mpg reflects the balance of performance and efficiency for a premium vehicle. In the broader reliability context, the CTS’s 2009 model year sits within a decade that saw the highest complaint volume in 2003 and the lowest in 2018, with the 2009 year recording 167 owner complaints—primarily engine‑related—and five recalls, indicating a moderate but not exceptional reliability profile for the brand’s flagship sedan.

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 2009 model year represents a low point in the complaint trajectory for this generation, with 167 complaints continuing the steady decline from the 2003 high of 321, yet it diverges from the surrounding years with a notable spike to 5 recalls—up from 2 in 2008 and higher than the 2 recorded in 2011—despite zero investigations and zero fire-related complaints. While complaints continued their downward arc to just 108 by 2011, the 2009 model carries more recall activity than its immediate successor years, though its specific top complaint categories (Engine leading with 40, followed by Power Train at 20) reflect the data without specifying root causes. Positioned between the 2008 model’s 175 complaints and 2011’s 108, the 2009 model benefits from diminishing owner-reported issues but carries elevated factory correction activity compared to the flanking years. With only 10 crash-related complaints and no fire incidents reported, the safety profile appears stable, though the recall spike suggests concentrated quality corrections that resolved prior to 2011’s lower recall count. Given the low absolute complaint volume and the absence of ongoing investigations, this represents a reasonable acquisition year, provided the specific recall work has been documented and completed.
