1998 Mazda Millenia

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 Millenia.

The 1998 Mazda Millenia, part of a model line produced from 1991 through 2003, recorded only 29 total owner complaints and zero recalls, a standout figure given that the highest complaint year for the line was 1995 with 99 complaints. Its top trouble area was engine and engine cooling, yet the low total places this model year well below the peak and closer to the model's best reliability years, suggesting a relatively trouble-free point in the Millenia's lifecycle.

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.

The 1998 model year recorded 29 complaints, exceeding the 18 seen in both 1996 and 1997 but remaining far below the 1995 figure of 99, while zero recalls and zero investigations appear across every year in this federal record. Its 58 TSBs marked a decline from the 93 issued for 1997 and sat well under the 110 and 103 logged for 2001 and 2002, placing 1998 in a middle period of moderate activity before the late-generation TSB rise. Top complaint areas were Engine & Engine Cooling and Power Train with four each, followed by Fuel System, Gasoline at three and Wheels at two, though the data does not specify root causes; the year also recorded three crash complaints and zero fire complaints. With no recalls or investigations on record, complaint counts in the moderate mid-range rather than the outlier high, and TSBs lower than the surrounding 1997 and 2001 peaks, 1998 shapes up as a comparatively reasonable year to buy, contingent on confirming that the documented Engine, Power Train, and Fuel System complaints have been inspected in the individual vehicle’s history.
