2002 Mazda B-Series

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2002 B-Series.

Body TRUCK

The 2002 Mazda B-Series is a compact pickup truck that shares its body-on-frame platform with the Ford Ranger, and while it logged only 29 total owner complaints—a moderate figure for the model’s 1996–2009 production run—the most frequently cited issue involved the engine and engine cooling system, a concern underscored by two official recalls. Positioned between the peak-complaint 1999 model (80 complaints) and the near-trouble-free 2009 model (4 complaints), the 2002 B-Series represents a middle ground in the nameplate’s reliability history, offering a generally serviceable ownership experience but with a notable engine-related caution for prospective researchers.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 mi; spark plugs every 100,000 mi; coolant at 45,000 mi. The big-interval services (at 45,000 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.

Federal data places the 2002 Mazda B-Series in a clear downward trend for owner complaints, recording 29 complaints versus 59 in 2000 and 38 in 2001, with two recalls matching the low counts of 1996 and 1997. Across this generation, complaints peaked at 80 in 1999 and generally receded through the early 2000s before a subsequent rise in 2004; 2002 sits in this quieter mid-generation interval alongside zero investigations and 122 TSBs, though the federal data does not specify root causes for its top complaint areas of Engine & Engine Cooling, Power Train, Air Bags, and Tires. The model also registered five crash complaints and zero fire complaints. Because it falls on the lower-complaint side of the generational arc with minimal recalls and no federal investigations, 2002 is one of the more favorable years in this generation to buy.
