2004 Mazda Mazda3

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 Mazda3.

Body PASSENGER CAR

Serving as the inaugural year of a complaint history spanning from 2004 to 2024, the 2004 Mazda3 introduced the passenger car nameplate alongside a notable set of early-production challenges. The vehicle has accrued 170 owner complaints and three recalls, with air bag deficiencies representing the most prominent area of concern. While this complaint volume sits well below the model's problematic peak of 686 in 2010, the 2004 model's foundational position in the lineage means its specific air bag vulnerabilities remain a critical factor for researchers evaluating the long-term durability and safety of this vintage.

Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 35 · 550 CCA battery, OE oil filter LF8J14302. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

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 75,000 mi; coolant at 60,000 mi. The big-interval services (at 60,000 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 2004 Mazda Mazda3, as the first model year of the generation, logged 170 complaints and 3 recalls—a complaint count higher than the 2005 model's 103 but comparable to the 2006's 166. Across the generation, complaints trended upward to a peak of 686 in 2010 before declining, so 2004 sits near the start of that arc with moderate owner reports. The top complaint areas were air bags (23), engine and engine cooling (21), and service brakes (21), with 24 crash-related complaints and 2 fire complaints; the data does not specify root causes for these issues. With 247 TSBs, the 2004 model had fewer service bulletins than many later years (e.g., 880 in 2014), suggesting it was not an outlier in terms of documented fixes. While the first year often carries teething risks, the 2004's complaint and recall numbers are not extreme relative to the generation's later spikes. This is a cautiously acceptable buy if you prioritize a lower-cost entry point and verify that the top complaint areas have been addressed, but later model years (e.g., 2006-2007) may offer slightly more refinement with similar complaint levels.
