The 2025 Honda Odyssey belongs to the 5th generation (2018-present), built with 3.5L direct-injection SOHC i-VTEC V6 (J35Y6) - 9-speed automatic (LX/EX/EX-L, 2018-2019) or 10-speed automatic with Idle-Stop (Touring/Elite 2018-2019, all trims 2020 onward). It takes 0W-20 full synthetic. Oil changes run 7,500 - 10,000 miles on the Maintenance Minder. This sits in the middle of the generation run, generally the most sorted point in a design before end-of-run cost reductions.
A 2025 Honda Odyssey is a year old in 2026, which at an average 12,000 miles a year puts it around 12,000 miles - still under warranty. At roughly 12,000 miles this vehicle is still early enough to be inside the range most manufacturer warranties cover. The most valuable thing you can do this early is start a service record - it is worth real money at resale and it is nearly impossible to reconstruct later. This manufacturer schedules it by Maintenance Minder code rather than a fixed odometer number - the car itself decides the interval based on how it has been driven - so there is no single mileage to give here; see what is due at each mileage below for the typical points those codes appear.
The fault most worth knowing about on this generation is American Honda recalled approximately 107,000 MY2018-2019 Odysseys in November 2018 for power sliding door rear latches that could stick. Owners also report An August 2020 recall bundle covered approximately 608,000 MY2018-2020 Odyssey (plus Passport/Pilot) for gauge-cluster software, rear-camera display software, and sliding-door outer handle cable water intrusion; and Too new (2023-2026 model years) for durable long-term failure patterns to have emerged as of this research. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

| Interval | Service |
|---|---|
| Maintenance Minder Code A | Replace engine oil |
| Maintenance Minder Code B | Replace engine oil and oil filter, Inspect front and rear brakes, Inspect tie rod ends, steering gearbox, and boots, Inspect suspension components, Inspect driveshaft boots, Inspect brake hoses and lines (including ABS/VSA), Inspect all fluid levels and condition of fluids, Inspect exhaust system and fuel lines and connections |
| Sub-item 1 | Rotate tires |
| Sub-item 2 (typically every 15,000 mi) | Replace engine air cleaner element - every 15,000 mi if you drive in dusty conditions, Replace dust and pollen (cabin) filter - every 15,000 mi if you drive primarily in urban areas with high soot from industry or diesel traffic, Inspect drive belt |
| Sub-item 3 | Replace automatic transmission fluid - applies to every trim now that the 10-speed automatic is standard across the lineup (the 2018-2019 manuals excepted Touring/Elite from this item; that exception, and its severe-duty mileage note, are both gone from the 2020 manual onward). Honda publishes no mileage for this item on this generation; the Maintenance Minder alone decides |
| Sub-item 4 (typically every 60,000 mi) | Replace spark plugs, Replace timing belt and inspect water pump - the J35 V6 is belt-driven, not chain-driven, even with this generation's direct-injection redesign. Honda's manual publishes no normal-duty mileage for this item - the Maintenance Minder alone decides, based on driving conditions. The manual's only printed number is a severe-duty override: if you regularly drive in very high temperatures (over 110 F/43 C) or very low temperatures (under -20 F/-29 C), replace every 60,000 mi. Independent shops and Honda dealers commonly report the Minder flagging this item somewhere around 100,000-105,000 mi under normal use - that figure is a widely observed estimate, not a Honda-published one., Inspect valve clearance |
| Sub-item 5 | Replace engine coolant |
| Sub-item 7 | Replace brake fluid. If a Maintenance Minder message for item 7 does not appear within 36 months of the display being reset, change the brake fluid every 3 years |
The table above is indexed by service interval. This is the same schedule indexed by odometer reading, for when you know your mileage and want the list. If your odometer sits between these figures, work back to the last one you passed and catch up anything skipped.
| Odometer | Service due |
|---|---|
| 30,000 mi (48,000 km) | Replace engine air cleaner element - every 15,000 mi if you drive in dusty conditions, Replace dust and pollen (cabin) filter - every 15,000 mi if you drive primarily in urban areas with high soot from industry or diesel traffic, Inspect drive belt. |
| 60,000 mi (97,000 km) | Replace engine air cleaner element - every 15,000 mi if you drive in dusty conditions, Replace dust and pollen (cabin) filter - every 15,000 mi if you drive primarily in urban areas with high soot from industry or diesel traffic, Inspect drive belt, Replace spark plugs, Replace timing belt and inspect water pump - the J35 V6 is belt-driven, not chain-driven, even with this generation's direct-injection redesign. Honda's manual publishes no normal-duty mileage for this item - the Maintenance Minder alone decides, based on driving conditions. The manual's only printed number is a severe-duty override: if you regularly drive in very high temperatures (over 110 F/43 C) or very low temperatures (under -20 F/-29 C), replace every 60,000 mi.

| 90,000 mi (145,000 km) | Same as the 30,000 mi service. |
| 120,000 mi (193,000 km) | Same as the 60,000 mi service. |
| 150,000 mi (241,000 km) | Same as the 30,000 mi service. |
Honda schedules this vehicle by Maintenance Minder code rather than by odometer, so the mileages above are the typical points those codes appear - the car itself decides, based on how it has been driven.

Maintenance keeps these away, but when the dash does light up these are the codes this vehicle throws most often - each with what it means and what the repair actually costs.
