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 2023 Cadillac CT4 carries the lightest federal footprint of this generation to date, with 3 complaints, 1 recall, 0 investigations, and 543 TSBs. That is down from 20202022, which ranged from 5–7 complaints and 2–4 recalls per year, and lower than 2024, which saw complaints rebound to 7 even as recalls fell to 0; 2025 then registers 2 complaints and 0 recalls with TSBs continuing to decline. Across the generation, complaints stay in single digits and fluctuate, while recalls and TSBs trend steadily downward—suggesting model maturation—so the 2023 model sits near the bottom of the defect-activity arc. The top complaint areas are scattered one-report categories (steering/vehicle speed control/brakes, electrical/engine/fuel, and powertrain), and there are 0 crash and 0 fire complaints, so the data shows no concentrated safety pattern; the root causes are not specified. Given that low combined activity, the 2023 CT4 looks like one of the stronger used-buy years in this generation, provided a normal pre-purchase inspection checks out.
