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 model year sits within a pronounced downward correction following the 2003 peak, when complaints reached 2,013 and technical service bulletins hit 388, with 2004 figures dropping to 1,016 complaints and 298 TSBs despite recalls remaining elevated at 22 units. As the second year of its generation, 2004 demonstrates the expected post-launch stabilization, with metrics continuing to decline toward 2005's 686 complaints and 2006's 430 complaints, well below the generation's initial spike. Federal records identify Power Train and Air Bags as the dominant complaint categories for this specific year, with 289 and 198 filings respectively, though the data does not specify underlying mechanical causes for these concentrations. This positions 2004 as a transitional year that avoids the worst excesses of 2003 while still carrying higher recall activity than the later 2006-2007 period. For a prospective buyer, this makes the 2004 Accord a defensible choice within its generation, offering substantially fewer reported complaints than the inaugural 2003 model provided recall work is documented.
