2006 Cadillac CTS

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 CTS.

Body PASSENGER CAR

The 2006 Cadillac CTS is a passenger car that calls for 5.05 quarts of 5W-30 API engine oil. With 272 owner complaints and seven recalls—led by air bag issues—it sits midstream in the model’s 2003–2019 reliability arc. It carries fewer reported problems than the launch-year 2003 (321 complaints) but significantly more than the refined 2018 model (8 complaints), marking it as a transitional year before major quality improvements took hold.

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 first-generation Cadillac CTS shows a clear complaint decline across its lifespan, from 321 in 2003 down to 218 by 2007, with the 2006 model year sitting at 272 — a modest improvement over 2005's 284 but still well above the generation's endpoint. Recalls held steady at seven from 2004 through 2007, meaning the 2006 carries the generation's maximum recall burden alongside its 2004, 2005, and 2007 siblings, while investigations peaked at three in both 2005 and 2006 before dropping to two in 2007. Meanwhile, TSBs climbed steadily from 528 in 2003 to 719 in 2006, indicating GM was actively issuing technical service bulletins throughout this period, though the data does not specify whether these addressed the same categories that generated consumer complaints. The 2006's top complaint areas — Air Bags at 68, Service Brakes at 32, Power Train at 31, and Electrical System at 16 — along with 23 crash complaints and 2 fire complaints, suggest the airbag system is the dominant concern for this model year, though the federal record does not identify a root cause. Positioned late in the generation's arc, the 2006 benefits from accumulated manufacturer service knowledge reflected in its higher TSB count, but it also carries the generation's peak investigation count and recall volume. For a buyer, the 2006 is a marginal choice: it is an improvement over the 2003–2005 models on complaint volume, but the 2007 offers meaningfully fewer complaints with the same recall profile, making it the better late-generation pick if the option exists.
