GMC Acadia Maintenance Schedule
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-06-25 · confidence: medium
Recommended service intervals for the 2024-2025 (new gen) GMC Acadia (2.5L turbo-4 (LK0); 0W-20 dexos1 Gen 3; 8-speed auto).
In short: the 2024-2025 (new gen) GMC Acadia needs an oil change gm oil life system ~7,500 mi (up to ~12,000 / 12 mo under light use); severe sooner, tire rotation every 7,500 mi, and has a timing chain (no scheduled replacement). Full service schedule below.
| Oil change | GM Oil Life System ~7,500 mi (up to ~12,000 / 12 mo under light use); severe sooner |
|---|---|
| Tire rotation | Every 7,500 mi |
| Brake fluid | Inspect/exchange ~every 2-3 yr |
| Engine air filter | ~45,000 mi |
| Cabin air filter | ~22,500 mi |
| Transmission fluid | 8-speed auto; fluid & filter ~100,000 mi (towing/severe ~45k-60k) |
| Coolant / antifreeze | DEX-COOL, first ~150,000 mi / 5 yr |
| Spark plugs | ~100,000 mi |
| Timing belt / chain | Timing CHAIN — no scheduled replacement |
Major milestones: 22.5k cabin filter; 45k air filter; 100k plugs + trans; 150k coolant.
GMC Acadia note: The all-new 2024 Acadia drops the old V6 for a turbo-four with an 8-speed auto. Being turbocharged, keep 0W-20 dexos1 Gen 3 on time and don't stretch oil past the monitor, especially when towing.

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.
