1998 Toyota 4runner — V6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 4runner V6.

Body SUVEngine V6

The 1998 Toyota 4Runner V6 is a body-on-frame SUV powered by a V6 engine that calls for 5.3 quarts of 5W-30 API motor oil at service intervals, placing it squarely in the third generation of a platform that would run largely unchanged through the turn of the millennium. With 267 total owner complaints logged against it and five recalls issued, this model year sits in a relatively quiet stretch of the 4Runner's complaint history, which spans from 1990 through 2026 — well below the 707-complaint peak that would come in 2003 and far from the single-digit figures of recent years. The most frequently cited complaint area is the vehicle's structure, a category that encompasses body and frame concerns rather than powertrain failures, suggesting that for researchers tracking long-term durability, the 1998 V6 represents a middle-of-the-road chapter: not the cleanest year on record, but far from the model's trouble spots.

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 federal record for this generation reveals a steep escalation in complaints starting in 1995, jumping from 80 in 1994 to 184 in 1995, and eventually peaking at 494 in the year 2000. The 1998 model year sits near the apex of this high-complaint arc, registering 267 complaints—slightly lower than 1997's 270, but vastly higher than the early 1990s models that hovered between 50 and 85 complaints. For the 1998 4Runner specifically, structure issues lead the complaint categories at 57 incidents, followed by suspension (38) and tires (33), though the data does not specify the root causes for these failures. While 1998 ties for the highest recall count in its immediate era with 5 recalls—suggesting active manufacturer intervention—it also carries 19 crash and 6 fire complaints. Given its position squarely within the generation's worst complaint trend and its elevated structural and suspension issues, the 1998 model is not a standout year to buy; shoppers should strongly consider earlier, lower-complaint model years instead.
