2025 Mazda 3

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 3.

Transmission Automatic (S6)

The 2025 Mazda 3 is paired with an automatic (S6) transmission and carries EPA fuel-economy ratings of 27/37/31 mpg. Its early reliability record is comparatively light, with just seven owner complaints logged so far and a single recall on record. Most of those complaints cluster in the Forward Collision Avoidance category, making that the clearest area to watch even as the low overall volume suggests a quiet start for this 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.

Owner complaints about the 2025 Mazda 3 lead in one area — the forward collision avoidance, 2 of 7 reports (29%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 2 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the forward collision avoidance pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
