2004 Toyota Tundra — V6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 Tundra V6.

Body TRUCKEngine V6Transmission Automatic 4-spd

The 2004 Toyota Tundra V6 is a full-size truck built on a traditional body-on-frame platform, powered by a V6 engine that requires 5.5 quarts of 5W-30 API oil and is paired with a 4-speed automatic transmission, achieving EPA fuel economy ratings of 15/18/16 mpg across city/highway/combined cycles. This model year falls within a complaint range of 1 to 1,032 across the Tundra's 1999-2016 lifespan, with the 2004 recording 465 total owner complaints—well below the peak year of 2000 but substantially above the inaugural model's single complaint—alongside 13 manufacturer recalls. The Tundra's complaint trajectory across this span suggests that while the 2004 represents a notably improved reliability picture compared to the model's troubled early years, structural concerns remained the most frequent complaint area, indicating persistent engineering challenges that researchers should consider when evaluating this model year within the broader Tundra lineage.

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 2004 Tundra sits mid-generation with 465 complaints — above the 2003 (411) and 2005 (374) levels but well below the 2000 launch-year spike (1,032) and the 2006 uptick (545). Its 13 recalls match the generation's peak (tied with 2006, 2008, and 2009), while its six investigations represent the highest count across all listed years. Technical service bulletins jump sharply to 201 from 139 in 2003, signaling increased dealer-level attention; the data doesn't specify root causes for the leading complaint categories of Structure (125), Suspension (84), and Air Bags (40). Crash-involved complaints total 24 with one fire report. Compared to adjacent model years, 2004 shows elevated regulatory scrutiny and service activity without the extreme complaint volume of the generation's bookends. A buyer should verify recall completion and inspect frame and suspension components closely, but the year avoids the worst complaint spikes of the generation.
