2001 Toyota Tundra — V6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 Tundra V6.

Body TRUCKEngine V6Transmission Automatic 4-spd

The 2001 Toyota Tundra V6 is a full-size truck powered by a V6 engine paired with an automatic 4-speed transmission, and it carries a 5.5-quart oil capacity requiring 5W-30 API viscosity. Its EPA fuel economy of 15 city, 18 highway, and 16 combined mpg reflects the era’s efficiency standards. In the model’s reliability history—spanning 1999 through 2026—the 2001 year sits between the peak complaint year of 2000 (1,032 complaints) and the near-flawless 1999 (1 complaint), with 420 total owner complaints, 6 recalls, and Structure as the top complaint area, marking it as a transitional year that researchers should note for its moderate but not exceptional reliability record.

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 2001 Toyota Tundra generated 420 complaints and 6 recalls, representing a steep decline from the 1,032 complaints and 9 recalls recorded in 2000 and sitting below the 511 complaints filed for 2002. Across the early model years visible in the federal record, 2001 sits near the lower end of the activity band, with its complaint count exceeded by 2002, 2004, and 2006, and its recall count matched only by 2002 before double-digit recalls begin in 2003. The data lists Structure (124 filings) and Service Brakes, Hydraulic (83 filings) as the top complaint areas for 2001, alongside 28 crash-related and 2 fire-related complaints, though no root causes are specified. Within the arc of the generation, 2001 follows the sharp 2000 spike and avoids the escalating investigations and recalls that intensify through 2003–2006. Given its comparatively moderate federal footprint relative to surrounding model years, the 2001 Tundra stands as a comparatively stable choice in that generation.
