2023 Mazda CX-30

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 CX.

Transmission Automatic (S6)

The 2023 Mazda CX-30 is a compact crossover built on Mazda's 30 platform and paired with a six-speed automatic transmission, returning EPA fuel economy of 26/33/29 mpg city/highway/combined. Across the model's 2020–2025 complaint history, this year records the fewest owner complaints at just 22—well under the 99 reported in 2021—alongside a single recall and air bags as the top complaint area. For researchers, that places the 2023 CX-30 at the most favorable point in the generation's reliability record, meaning it carries the lowest documented owner-complaint volume of any year covered.

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.

For the 2023 Mazda CX-30, federal data shows it sits at the lowest point of the generation's complaint arc, dropping significantly from the 2021 peak of 99 complaints down to just 22. Recalls reached a generational low of one in 2023, down from three in the 2020 launch year, while technical service bulletins continued a steady decline to 306, indicating maturing production quality. Although 2024 saw a slight uptick to 27 complaints and two recalls, the 2023 model's top complaint areas—Air Bags, Visibility/Wiper, and Service Brakes/Forward Collision Avoidance—are fragmented with only two reports each, and the data does not specify a root cause for these isolated issues. With zero fire complaints and only five crash complaints reported, the 2023 model clearly benefits from the manufacturer having already ironed out early production bugs. Consequently, the 2023 CX-30 stands out as a smart, low-risk purchase in the used market.
