Honda Odyssey 2018–present · Maintenance schedule & cost to maintain

Not a Honda schedule item. Have it checked about once a year and every time tires or suspension parts go on. Misalignment and worn dampers both cup tread, and this generation's rear shocks are a known replacement (see the problem list). New shocks or new tires without an alignment check waste part of what you just paid for.

Not a Honda schedule item, but a real cost line. Buy the size and load index on the door-jamb label: 235/60R18 103H or 235/55R19 101H, by trim. Rotate at every minder code 1. Worn shocks cup tires, so if a set is wearing unevenly, check the rear shocks before blaming the tires.

Honda's footnote for the 9-speed: slow mountain driving or towing heats the fluid, so change it at 60,000 miles or 3 years, then every 30,000 miles or 2 years, sooner than the minder would ask. If you tow or live in the hills, that is your schedule. The footnote excludes Touring and Elite, which have the 10-speed. The fluid is Honda ATF-Type 3.1 or higher.

Honda prints no mileage and no severe number for the 10-speed. Code 3 on the minder calls it. Dealer schedules print 90,000 miles, and one prints 45,000 for severe use, but neither figure appears in Honda's manual. The fluid is Honda ATF-Type 2.

The J35Y6 is belt-driven. The minder calls the belt as code 4 with the plugs, and Honda's press kit calls that a 100,000-mile tune-up. Honda's footnote cuts it to 60,000 miles if you regularly drive in temperatures over 110°F or under -20°F. That is the only severe number Honda prints for the belt, so it is listed here. Outside those climates, wait for code 4.

Honda gives no pad mileage. Every B service includes a front and rear brake inspection, so replace on measured thickness, not on a guess.

No Honda interval. This generation's rear shocks rust through at the top and leak, commonly by 50,000-80,000 miles (see the problem list), which is why the check sits here. A worn damper lets the tire bounce and cup its tread. Replace in pairs and get an alignment after.

Every B service tells the shop to inspect the driveshaft boots, so a tear should be caught early. Grease flung from a torn boot coats the rotor and soaks into the pads, which then grab or pull. Caught early, a boot is a small add-on. A worn-out axle costs far more.

Code 4 replaces all six plugs and inspects valve clearance, alongside the timing belt. Honda prints no mileage for it. Honda's press kit calls it a 100,000-mile tune-up, and a Honda dealer schedule prints 100,000 for the plugs. Honda also says to adjust the valves at any A, B, 1, 2 or 3 service if they are noisy.

No Honda interval. This V6 sits on active, electronically driven mounts front and rear that cancel the shake when VCM shuts cylinders off. Tells of a worn mount: a clunk or thud when shifting, and vibration at idle. A loose engine moves enough to strain hoses and parts around it, so a bad mount should not ride.

No Honda interval, though every B service includes a suspension inspection. Bushings typically wear out around 100,000 miles, sooner on rough roads. A worn one lets the wheel shift out of alignment, so an alignment that will not hold points here. Budget an alignment after replacing them.

Code 5 calls it, and Honda's manual prints no mileage for it. A Honda dealer schedule and a Honda enthusiast guide both put the factory Type 2 fill at 10 years or 120,000 miles, then every 5 years or 60,000. Those figures are theirs, not the manual's. Refill with Honda Long-Life Type 2, 50/50, about 1.7 gallons.

Code 7 on the minder, with a calendar backstop: if code 7 has not come up within 36 months of the last reset, Honda says change it every 3 years. Honda publishes no separate severe interval. The footnote means a low-mileage van still goes on the 3-year clock. The spec is Honda Heavy Duty DOT 3.
