Body PASSENGER CAR

The 2004 Cadillac CTS is a passenger car that uses 5W-30 API oil with a 5.1-quart capacity, placing it among early iterations of the model. With 229 total owner complaints and 7 recalls, its most frequent issue area is the Power Train. In the model’s complaint history spanning 2003 to 2019, the 2004 CTS falls below the peak of 321 complaints recorded for the 2003 model year, indicating a slight improvement in early reliability but still reflecting the teething problems common to a new generation.

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.

Compared to the 2003 model year’s 321 complaints, the 2004 Cadillac CTS logged 229 owner complaints, yet recalls rose from four to seven and the model recorded its first two federal investigations in the dataset. The 2004 model sits early in an arc where complaint counts remained elevated—rebounding to 284 in 2005 and 272 in 2006—before a sustained long-term decline set in and investigations ended after 2007. Technical service bulletons climbed steadily from 567 in 2004 to a peak of 2,065 by 2014, reflecting increasing documented service activity as the model line aged. For 2004 specifically, the leading complaint areas were Power Train (42), Electrical System (23), Air Bags (16), and Service Brakes (15), accompanied by 26 crash-related and 1 fire-related complaint, though the data does not specify root causes. Because 2004 offers fewer complaints than 2003, 2005, and 2006 but shares the elevated recall count seen through 2007 and introduces the first investigations, it is a marginally acceptable year to buy provided maintenance records verify recall completion.
