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

Body SUVEngine V6Transmission Automatic 5-spd

The 2004 Toyota Highlander V6 is an SUV powered by a V6 engine paired with an Automatic 5‑spd transmission, delivering EPA‑rated fuel economy of 17/23/19 mpg and requiring 4 qt of 5W‑30 API oil. Owner feedback for this model year totals 286 complaints, with the power train identified as the top problem area and five recalls issued. When viewed against the broader Highlander complaint history from 1997 to 2026—where the lowest recorded figure is just one complaint in 1997 and the highest peaks at 475 complaints in 2021—the 2004 model’s 286 complaints place it toward the higher end of that spectrum. This suggests that, relative to its lineage, the 2004 Highlander exhibits moderate reliability, reflecting a noticeable share of issues compared with both the earliest and most recent years in the data set.

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; spark plugs at 120,000 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.

The 2004 Toyota Highlander generated 286 federal complaints, five recalls and one investigation, exceeding the 270 complaints and two recalls of the 2003 model and the 225 complaints and six recalls of the 2005 model. Recalls in 2004 (5) are higher than in 2003 (2) but comparable to the following year (6), while the single investigation appears only in 2004 and 2006, marking the first federal probe of this generation. Complaint volumes rise sharply from 2001 through 2008, placing 2004 in the early upward arc of reported issues before the peak in 2008, and recalls climb gradually from zero in earlier years to five in 2004. The primary complaint categories for 2004 are Power Train (52), Vehicle Speed Control (29), Steering (28) and Visibility (17), and it accounts for 32 crash‑related and 3 fire‑related complaints, highlighting safety‑relevant concerns. Given its above‑average complaint count and the emergence of official investigations, the 2004 model is generally a less optimal choice unless the specific vehicle has a clean service history.
