2004 Mazda MPV

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

Body VANTransmission Automatic 5-spd

The 2004 Mazda MPV, a VAN, comes paired with an automatic five‑speed transmission and delivers EPA fuel‑economy ratings of 16 city, 23 highway and 18 combined mpg, with its 23‑mpg highway figure included in those numbers. In that model year owners filed 96 complaints, primarily concerning the engine and cooling systems, and the vehicle was subject to five recall campaigns, situating its reliability within a broader history that reached a high of 155 complaints in 2000 and a low of just two in 1999. Overall, the 2004 model year sits in the middle of the MPV’s complaint trajectory, showing fewer issues than the 2000 peak but more than the 1999 low.

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; coolant every 30,000 mi. The big-interval services (every 30,000 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.

In the 2004 Mazda MPV year, complaints stood at 96 with five recalls and three investigations, a moderate level that sits below the peak of 155 complaints in 2000 but above the low single‑digit complaints of 1999. Compared to the preceding year (2003), complaints fell from 114 to 96, while recalls increased from four to five, indicating a slight uptick in formal safety actions. The following year (2005) saw a sharper decline to 42 complaints and three recalls, suggesting a downward trend in reported issues after 2004. The 2004 model’s top complaint areas—Engine & Engine Cooling (29), Air Bags (15), Electrical System (9), and Power Train (6)—highlight specific component concerns that were not dominant in earlier years. With only eight crash complaints and one fire complaint, the overall safety profile is relatively mild compared to the 2000 peak. Therefore, 2004 is a reasonable choice if you can find a vehicle with a clean service history, but you should be vigilant about engine cooling, airbags, and electrical components.
