2025 Mazda CX-30

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

Transmission Automatic (S6)

The 2025 Mazda CX-30 carries the brand's "30" platform into another model year, with a 6-speed automatic and a 26/33/29 mpg EPA rating anchoring its powertrain and efficiency credentials. Within a nameplate that has logged owner complaints every year since its 2020 introduction, this version registers 25 filings and a single recall, with no single subsystem dominating the log. That places the 2025 model year in the calmer end of the CX-30's 2020-2025 arc, running just above the 22-complaint low set in 2023 and well clear of the 99-complaint peak that defined the 2021 model year.

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 75,000 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.

Across the CX‑30’s second generation, total complaints dropped sharply after a spike in 2021 (99 complaints) and have hovered between 22 and 32 per year since 2022. Recall activity mirrors this decline, falling from three recalls in 2020 to a single recall each year from 2022 onward, with 2025 matching the low point at one recall. Technical Service Bulletins (TSBs) have also been decreasing steadily, from 675 in 2020 to just 139 in 2025, indicating fewer manufacturer‑identified issues over time. The 2025 model sits at the bottom of both complaint and recall counts, with only 25 complaints—primarily “Unknown or Other” and electrical‑system reports—and no fire complaints, suggesting it benefits from the generation’s overall improvement trend. Consequently, 2025 appears to be one of the most reliable years in the CX‑30’s recent run and is a strong candidate for purchase.
