Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 40,000 mi; coolant every 10,000 mi. The big-interval services (every 10,000 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 CX-30’s federal record shows a generational arc that peaked early, with 99 complaints in 2021 and 3 recalls in 2020, before cooling into a lower-activity phase. For 2024, complaints stand at 27—slightly above 2023’s 22 and 2025’s 25 but far below the 2021 high—while TSBs have trended steadily downward to 229 from 675 in 2020. Recalls ticked up to 2 in 2024 after dropping to 1 in both 2022 and 2023, though investigations remain at zero across every year shown. The top 2024 complaint categories—each with 3 filings—cover lane departure/forward collision avoidance, unknown/other, air bags, and forward collision avoidance, yet the data does not specify root causes. The year also records 2 crash complaints and 1 fire complaint, placing 2024 in a mature, stable period of the model cycle. That profile makes the 2024 CX-30 a sound used-buy candidate, provided buyers confirm all recalls have been completed.
