2006 Toyota 4runner Sport — V8

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 4runner Sport V8.

Body SUVEngine V8Transmission Automatic 5-spd

The 2006 Toyota 4Runner Sport V8 is an SUV equipped with a V8 engine and a 5-speed automatic transmission, returning an EPA-estimated 15 city, 18 highway, and 16 combined mpg. Routine service parameters, such as a 5.5-quart oil capacity requiring 5W-30 API viscosity, define the straightforward mechanical footprint of this powertrain, though its reliability record introduces a critical caveat for researchers. This model year occupies a complicated position in the 4Runner's reliability history, as 380 total owner complaints and five recalls—driven primarily by the structure category—mean the vehicle's enduring reputation must be weighed against documented structural concerns.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 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.

Owner complaints about the 2006 Toyota 4runner Sport lead in one area — the structure, 107 of 380 reports (28%), well ahead of the next concern. None of this vehicle's 5 recall campaigns target the structure, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 28 of the reports describe a crash and 3 a fire — a small share of the total, but worth weighing against the structure pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
