2004 Honda Odyssey

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

Body VANTransmission Automatic 5-spd

The 2004 Honda Odyssey is a minivan equipped with a 5-speed automatic transmission that operates on 5W-20 API oil with a 4.5-quart capacity, achieving EPA ratings of 16/23/19 mpg city/highway/combined. Positioned within Honda's Odyssey lineage spanning 1990-2026, this model accumulated 584 owner complaints—well below the peak of 972 in 2002 but substantially above the low of just 1 complaint in 1994—with Power Train emerging as the most frequently cited concern area across 13 total recalls. The 2004 Odyssey represents a middle ground in the model's historical reliability pattern, neither reaching the complaint levels of earlier problem years nor matching the relative stability of its more dependable model years.

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 at 105,000 mi; coolant at 120,000 mi. The big-interval services (at 120,000 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 Odyssey sits at a notable inflection point: complaints drop to 584 from 940 in 2003 and 972 in 2002, marking the lowest volume since 2001, while recalls remain elevated at 13 — only slightly below the generation peak of 15 in 2003 — and TSBs fall sharply to 193 from 316 the prior year. The subsequent 2005 model year sees complaints rebound to 829 with 9 recalls, suggesting 2004's improvement was not sustained. Power Train leads 2004 complaints at 180, followed by Air Bags at 87, though the data does not specify root causes for either category; crash and fire complaints total 41 and 6 respectively. Across the 1999–2005 high-volume era, 2004 represents the complaint nadir but not a recall resolution, with federal metrics fluctuating rather than trending decisively downward. For a buyer, this makes 2004 a comparatively cleaner complaint year within a troubled generation, but the persistent recall count and sharp 2005 rebound counsel verifying that all 13 recalls were completed on any candidate vehicle.
