Full service timeline

Mileage	Service items	Details
8k mi	Engine oil and filter change — 0W-20 full synthetic (Honda Genuine); interval governed by the Honda Maintenance Minder System, which triggers Item A/B once calculated oil life drops to 15% — 7,500 mi is the typical ceiling under normal use Reset Maintenance Minder after service Check tire pressure and condition, adjust to door-placard spec Inspect all fluid levels: coolant, brake fluid, power steering (if equipped), washer fluid Inspect windshield wipers
15k mi	Engine oil and filter change per Maintenance Minder (0W-20 full synthetic) Tire rotation (Maintenance Minder Item 1) Inspect front and rear brake pads, rotors, and calipers Inspect suspension components and steering linkage Inspect CV axle boots
30k mi	Engine oil and filter change per Maintenance Minder (0W-20 full synthetic) Tire rotation Replace engine air filter (Maintenance Minder Item 5) Replace cabin air filter (Item 4) Inspect 10-speed automatic transmission fluid (Honda ATF DW-1) — level and condition Inspect serpentine drive belt for cracking or glazing Inspect brake fluid condition	View →
60k mi	Engine oil and filter change per Maintenance Minder (0W-20 full synthetic) Tire rotation Replace cabin air filter Replace engine air filter Replace brake fluid — DOT 3 (Honda recommends every 3 years regardless of mileage) Inspect spark plugs — iridium tipped; factory replacement interval is 105,000 mi, visual inspection only at this point Inspect 10-speed ATF (Honda ATF DW-1) condition and level; replace early if towing or other severe-duty use Inspect timing belt for surface cracking, glazing, or fraying — factory replacement interval is 105,000 mi / 7 years, whichever comes first	View →
90k mi	Engine oil and filter change per Maintenance Minder (0W-20 full synthetic) Tire rotation Inspect serpentine drive belt Inspect all suspension bushings, ball joints, and tie rod ends Inspect 10-speed automatic transmission fluid; replace now if operated under severe-service conditions (towing, heavy stop-and-go, extreme heat)	View →
105k mi	Replace timing belt — Honda's factory interval for the 3.5L V6 (J35Y6) SOHC engine is 105,000 miles or 7 years, whichever comes first. This is a real, non-optional major service: the J35 is an interference engine, and a broken or jumped belt causes valve-to-piston contact and severe internal damage. Do not defer it. Replace timing belt tensioner and idler pulley(s) — Honda recommends concurrent replacement with the belt itself Inspect (and, per most independent Honda shops, replace) the water pump — it shares access with the timing belt on this engine, so replacing it now avoids a second labor-intensive teardown later Replace spark plugs — iridium, factory interval 105,000 mi; commonly combined with timing belt service since the intake manifold is already partially disassembled Replace serpentine accessory drive belt if not already done
120k mi	Engine oil and filter change per Maintenance Minder (0W-20 full synthetic) Tire rotation Replace engine coolant — Honda Long Life Coolant Type 2 Replace 10-speed automatic transmission fluid (Honda ATF DW-1) under normal-service schedule Full brake inspection: pads, rotors, calipers, lines, master cylinder Inspect wheel bearings front and rear Inspect HVAC system and rear A/C unit (if equipped)	View →

Common symptoms for this vehicle

Check engine light on? Get a free code scan

If your check engine light is on, most auto-parts stores (AutoZone, O'Reilly, Advance) will read the code for FREE — no purchase required, just walk in. Bring the code back here and look it up at eli5cars.com/obd2 for the plain-English explanation.

Note: a scan only helps when there's an active fault code. For purely mechanical symptoms (noises, vibrations, leaks), a scan may show nothing — the suspects listed above are your starting point.
