1999 Toyota 4runner — V6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1999 4runner V6.

Body SUVEngine V6Transmission Automatic 4-spd

The 1999 Toyota 4Runner V6 is an SUV powered by a V6 engine paired with a 4-speed automatic transmission, a combination requiring 5.3 quarts of 5W-30 API oil to achieve an EPA-rated 16 city, 19 highway, and 17 combined mpg. Accumulating 335 total owner complaints—predominantly concerning the vehicle's Structure—along with 3 recalls, this model year represents a moderate point within the 4Runner's 1990–2026 reliability timeline. While it steers clear of the 707-complaint peak seen in the 2003 model year, it remains significantly above the 5-complaint low of 2026, positioning the 1999 4Runner as a fairly average entry in the nameplate's long-term dependability record rather than a standout.

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; spark plugs every 60,000 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 1999 4Runner sits in the middle of the third generation (1996–2002), where complaints rose sharply from 182 in 1996 to a generation peak of 494 in 2000. At 335 complaints, 1999 is above the 1997–1998 average but still below the 2000 spike, while its three recalls are the fewest of any year from 1996–1999, suggesting Toyota may have addressed earlier issues without triggering new safety campaigns. The top complaint area is "Structure" (74 reports), and the 30 crash complaints and 6 fire complaints are notable but not extreme for this era. TSBs hold steady at 82, matching 1998 and rising in later years, indicating the model was still accumulating service knowledge. Overall, 1999 is a middle-of-the-pack year for this generation—better than the high-complaint 2000 but worse than the lower-complaint 2001—making it a reasonable buy if you prioritize fewer recalls, though you should inspect for structural concerns.
