1998 Toyota 4runner — L4

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 4runner L4.

Body SUVEngine L4Transmission Automatic 4-spd

The 1998 Toyota 4Runner L4 is an SUV powered by an L4 engine paired with an automatic 4-speed transmission, delivering an EPA-rated 18 city and 22 highway mpg. Keeping that powertrain operational requires 5.3 quarts of 5W-30 API oil, a straightforward maintenance requirement for a utility vehicle of its era. While this model year generated 267 total owner complaints and 5 recalls predominantly focused on the vehicle's structure, it sits well below the 4Runner's historical peak of 707 complaints logged in 2003. For researchers, this positions the 1998 model as a moderately problematic midpoint in the nameplate's lineage, demonstrating that while its structural issues are notable, it is far from the most troubled chapter in the vehicle's history.

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 Toyota 4Runner generated 267 complaints, nearly matching 1997’s 270 while remaining well below the 335 and 494 complaints filed for 1999 and 2000, respectively. Across the contiguous 1996–2002 model run, federal filings trended upward in complaints and technical service bulletins, climbing from 182 complaints and 68 TSBs in 1996 to a high of 494 complaints and 95 TSBs by 2000, which places 1998 in the early phase of that escalation before the worst years. Its five recalls tied 1996 for the highest count within that span, though the data does not specify root causes, and its leading complaint categories were structure (57), suspension (38), and tires (33), alongside 19 crash-related and 6 fire-related complaints. Relative to later years in that same run, 1998 sidesteps the 2000 complaint surge and carries fewer TSBs than 2001–2002 models, suggesting it sits before the steepest part of the reported-issue escalation. Given that it precedes the 1999–2000 spike in owner complaints while still carrying elevated recall exposure, the 1998 4Runner represents a reasonable but not risk-free purchase, preferable to 1999–2000 but not as clean as the lower-complaint 1996.
