The 1998 Mazda B-Series has no open NHTSA recalls. Owners report 7 recurring issue clusters, led by “Throttle sticking and uncontrolled engine speed.” Mazda's Skyactiv engines use unusually high compression ratios (13:1 to 16:1) and require strict adherence to oil intervals — extending oil life on a Skyactiv engine accelerates carbon buildup on intake valves. Mazda's published Schedule 1 (severe) covers most US driving conditions.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Critical for safety and preventing major damage
Replace 0W-20 full-synthetic oil every 5,000 miles under Schedule 1. Schedule 2 (highway-only): 7,500 miles. Turbo engines: 5,000 miles regardless of schedule.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Rotate tires every 7,500 miles; every 5,000 on AWD models, where the front-biased coupling wears tires unevenly.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect brake pads, rotors, and parking brake at every oil change. Front pads typically last 35,000-50,000 miles.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Replace DOT 3 brake fluid every 30,000 miles or 36 months.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently
Replace engine air filter every 30,000 miles. Skyactiv-G direct injection is sensitive to airflow restriction — inspect at every oil change.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Replace ATF every 60,000 miles severe / 100,000 normal. Use Mazda FZ ATF — substitutes cause harsh 1-2 shifts and torque converter shudder.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Iridium spark plugs every 60,000 miles on Skyactiv-G 2.0L and 2.5L; 45,000 miles on the 2.5L Turbo.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Mazda FL-22 (yellow): first change at 120,000 miles or 10 years, then every 60,000. Do not substitute — silicate-free formula prevents water pump damage on Skyactiv engines.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
On AWD models, replace transfer case fluid and rear differential fluid every 60,000 miles.
Estimated cost — typical U.S. ranges
Dealer
~$105–$140
Shop
~$75–$100
DIY
~$15–$40
AWD/4WD vehicles only. Easy drain-and-fill on most platforms.
Extends the life of your vehicle and improves comfort
Replace cabin air filter every 15,000 miles. On most models it sits behind the glove box.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
Occupant deaths in fatal crashes (FARS)

How the 104 occupant deaths break down
80
driver deaths
24
passenger deaths
104
occupant deaths
Crash years covered: 1990–2024 This model year first appears in 1998 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.
FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.
Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.
Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.
IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.
Owner-reported problem signals
Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
