Acura MDX Maintenance Schedule
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-06-25 · confidence: high
Recommended service intervals for the 2022-2025 (4th gen; Type S from 2022) Acura MDX (Base 3.5L J35 V6 (TIMING BELT); Type S 3.0L turbo V6 (J30, TIMING CHAIN); both 0W-20, 10-speed auto, SH-AWD).
In short: the 2022-2025 (4th gen; Type S from 2022) Acura MDX needs an oil change maintenance minder oil-life (~7,500 mi / 12 mo typical; severe sooner), tire rotation every ~7,500 mi (minder code 1), and has a timing chain (no scheduled replacement). Full service schedule below.
| Oil change | Maintenance Minder oil-life (~7,500 mi / 12 mo typical; severe sooner) |
|---|---|
| Tire rotation | Every ~7,500 mi (Minder code 1) |
| Brake fluid | Every 3 yr (code 7), regardless of mileage |
| Engine air filter | ~30,000 mi (sooner if dusty) |
| Cabin air filter | ~15,000-30,000 mi |
| Transmission fluid | Per Maintenance Minder; commonly ~50,000-60,000 mi for the 10-speed |
| Coolant / antifreeze | First ~100,000-120,000 mi, then ~60,000 mi (Acura Type 2) |
| Spark plugs | Iridium ~100,000-105,000 mi (base V6 done with the belt; verify Type S per manual) |
| Timing belt / chain | Base 3.5L V6 = TIMING BELT (~105,000 mi / 7 yr, interference). Type S 3.0L turbo V6 = TIMING CHAIN |
Major milestones: 30k air/cabin filters; 3 yr brake fluid; base ~105k timing belt + water pump + plugs + coolant.
Acura MDX note: The two engines differ fundamentally: the base J35 V6 has a TIMING BELT needing ~105k-mi replacement (interference), while the Type S 3.0L turbo V6 uses a maintenance-free chain. Know which you have.
Acura MDX maintenance FAQ
How often does the Acura MDX need an oil change?
Maintenance Minder oil-life (~7,500 mi / 12 mo typical; severe sooner) — for the 2022-2025 (4th gen; Type S from 2022) Acura MDX. Use the severe-service interval if you mostly drive short trips, tow, or sit in traffic.
Does the Acura MDX have a timing belt or a timing chain?
Base 3.5L V6 = TIMING BELT (~105,000 mi / 7 yr, interference). Type S 3.0L turbo V6 = TIMING CHAIN.
What are the major service milestones for the Acura MDX?
30k air/cabin filters; 3 yr brake fluid; base ~105k timing belt + water pump + plugs + coolant.

Universal maintenance facts
- Full-synthetic oil typically lasts 7,500-10,000 mi / 12 mo, but turbo and direct-injection engines do better at 5,000-7,500 mi — synthetic resists thermal breakdown longer; turbos run hotter and DI engines suffer fuel dilution, so shorter intervals protect them.
- Rotate tires every 5,000-7,500 mi — front and rear tires wear at different rates; rotation evens wear, extends tire life, and is essential on AWD to avoid drivetrain strain.
- Replace brake fluid every 2-3 years regardless of mileage — brake fluid is hygroscopic — it absorbs water, which lowers its boiling point and corrodes ABS/brake parts, hurting braking when hot or wet.
- Follow the SEVERE schedule if you drive short trips, in cold/dusty/hot climates, in stop-and-go, or tow — those conditions are physically harder on oil, fluids and filters than highway cruising — and they describe most real drivers.
- Most cars since ~2010 use a timing CHAIN (no scheduled replacement); timing BELTS (replace ~60,000-105,000 mi) survive mainly on some VW/Audi and older engines — a snapped belt on an interference engine destroys the engine, so on belt cars the interval is non-negotiable — but most modern owners don't have a belt at all.
- Don't trust 'lifetime' transmission/CVT fluid — change it proactively (CVT ~30,000-60,000 mi, conventional auto ~60,000-100,000 mi) — transmission fluid degrades with heat; 'lifetime' often means the life of the warranty, and a fluid change is far cheaper than a transmission.
- Engine coolant is long-life (often first change ~100,000-150,000 mi), then repeats on a SHORTER cycle — long-life coolants protect ~10 yr first, but the corrosion inhibitors deplete, so later intervals are much shorter and easy to forget.
- Replace the cabin air filter ~every 15,000-30,000 mi or yearly, and the engine air filter ~every 30,000 mi — a clogged engine filter hurts airflow/economy; a clogged cabin filter weakens A/C/heat airflow and lets allergens in — both are cheap, high-satisfaction services.
