The 1998 Oldsmobile Aurora has no open NHTSA recalls. Owners report 6 recurring issue clusters, led by “Brake rotor wear and vibration under braking.” Oldsmobile closed in 2004, so every one of these is at least two decades old. That flips the maintenance question from mileage to age. Rubber, coolant, and brake fluid time out even on a car that barely gets driven. Models from about 1996 on use GM's Oil Life System and Dex-Cool coolant. Older ones run on fixed intervals and green coolant, and the two must never be mixed. Mechanically most of the lineup is shared GM hardware, so parts stay cheap and easy to find. The 3800 V6 in the Eighty-Eight and Ninety-Eight is one of the most durable engines GM ever built. The 3.1 and 3.4 V6 family has a well-documented lower intake manifold gasket weakness, and the Aurora's V8 needs a shop that knows Northstar-family cooling systems.
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
On 1996 and later cars, change when the Oil Life System asks and at least once a year. Earlier cars used a fixed 3,000 mile interval. At this age a 5,000 mile ceiling is the safer read, because worn seals and a tired PCV system dirty the oil faster than the computer assumes.

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Rotate every 7,500 miles. Check the DOT date code on the sidewall while you are under there. On a low-mileage car of this age, tires usually age out years before the tread wears out.

Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect pads and rotors at every service, and ask specifically about the rubber hoses and steel lines. Line corrosion is a common failure on twenty-year-old cars that lived through road salt.

Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Replace every 2 years regardless of mileage. Brake fluid absorbs water from the air, and decades-old fluid is the quiet cause of soft pedals and stuck calipers on cars this old.

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently
Drain and fill every 45,000 miles using Dexron VI. If the fluid has never been changed on a high-mileage car, ask for two or three drain-and-fills spaced out rather than a high-pressure flush.

~$330–$500

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Platinum or iridium plugs run to 100,000 miles. On the 3800 and 3.4 V6, replace the plug wires and coil boots at the same time. After this many years the insulation is brittle and a failing wire reads like a bad coil.
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.
Replace the belt and the tensioner together once either shows cracking, glazing, or noise. A weak tensioner chews through a new belt in short order.

~$195–$235

DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.
Replace every 30,000 miles. On most of the lineup this is a five minute job with a screwdriver.

5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Extends the life of your vehicle and improves comfort
Treat this as a 5 year job, not a mileage job. Cars from about 1996 on use orange Dex-Cool, earlier ones use green. Never mix them. While the system is drained, have the shop look for seepage at the intake manifold and water pump, which is where these engines usually start weeping.

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Test the battery and alternator once a year. Aging body control modules on this era of GM can pull a small current after shutdown, and a strong battery hides that problem until the day it does not.

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.
