2025 Cadillac CT4

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 CT4.

The 2025 Cadillac CT4 enters the current model year with a notably strong reliability profile, logging just two total owner complaints and zero recalls. While its top complaint area is categorized as "Unknown or Other," this sparse feedback represents the lowest complaint volume in the model's 2020-2025 history, dropping significantly from the seven complaints observed at the 2021 peak. For researchers, this position at the statistical floor of the CT4's complaint history signals that the vehicle has navigated past its early-generation complexities, establishing a more stabilized and predictable baseline for the nameplate.

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 2025 Cadillac CT4 sits at the end of a clear downward trend in complaints and recalls across the generation. Complaints peaked at seven in both 2021 and 2024, then dropped to just two for 2025—the lowest of any model year—while recalls fell from four in 2020 and 2021 to zero for both 2024 and 2025. Investigations have been absent since 2022, and technical service bulletins have steadily declined from 882 in 2020 to 228 in 2025, indicating that Cadillac has progressively refined the platform. The 2025 model’s two complaints, both in non-critical areas with no crash or fire reports, suggest the vehicle has reached a mature and stable point in its lifecycle. This makes the 2025 CT4 a good year to buy, as it benefits from the cumulative fixes of earlier years without inheriting their recall burden.
