How long will a 2009 Acura MDX last?
A well-maintained 2009 Acura MDX can reasonably reach around 200,000 miles or more, and many examples push past 250,000 miles with regular upkeep and careful driving.
What determines how long the MDX lasts
Maintenance history
Routine service—oil changes, filter replacements, fluid checks, and timely repairs—has the biggest influence on how long the SUV remains reliable. Vehicles with a thorough, documented service history tend to accumulate miles with fewer major failures.
Driving conditions
Highway cruising and steady speeds typically wear parts more slowly than heavy stop-and-go city driving. Climate and road salt also affect corrosion, cooling system health, and overall wear.
What to expect for a 2009 MDX with proper care
Given its age, a 2009 MDX that has been consistently maintained can commonly reach two to two-and-a-half times its initial mileage, with some owners reporting 300,000 miles or more. Real-world longevity also hinges on the condition of the engine, transmission, suspension, and cooling system, as well as prior accidents or body/frame repairs.
Maintenance to maximize longevity
Below are the core maintenance items that influence longevity for a 2009 MDX. Keeping up with these tasks is central to achieving high mileage.
- Oil changes and filters: Follow the owner's manual, typically every 5,000–7,500 miles with synthetic oil for optimal protection.
- Automatic transmission fluid: Monitor fluid condition and replace per guidance around 60,000–100,000 miles, or if shifting feels unusual.
- Cooling system: Regular coolant checks and a possible coolant/flush every few years; inspect hoses, radiator, thermostat, and water pump for leaks.
- Timing chain and related hardware: The 3.5L V6 uses a timing chain; have tensioners and guides inspected around 90,000–120,000 miles or if there are timing-related symptoms.
- Belts and pulleys: Serpentine belt and any drive belts should be inspected and replaced as needed to prevent accessory-drive failures.
- Suspension and steering components: Shocks/struts, control arms, ball joints, and bushings wear with mileage and road conditions; expect replacements around 100,000–150,000 miles depending on use.
- Brakes and tires: Regular inspection and replacement; pad/shoe life varies with driving style and terrain, while rotors may need resurfacing or replacement.
- Rust prevention and underbody care: In climates with road salt or coastal exposure, inspect for corrosion and address promptly to protect structural integrity.
- Battery and electrical components: Batteries typically last 3–5 years; address electrical issues promptly to prevent outages that can affect reliability.
Sticking to a disciplined maintenance schedule is the best way to maximize the MDX’s lifespan, especially as wear items accumulate on an SUV of this age.
Buying or owning a high-mileage MDX
When evaluating a used 2009 MDX, prioritize a complete service history, evidence of repairs, and a thorough mechanical inspection focused on the engine, transmission, cooling system, and suspension. A pre-purchase inspection by a qualified mechanic can reveal potential costly issues and help set expectations for remaining life.
Summary
The 2009 Acura MDX has a reputation for solid longevity when it receives regular, proactive maintenance. Realistically, owners can expect about 200,000 miles as a common milestone, with many reaching 250,000 miles or more and some pushing beyond 300,000 miles with diligent care. The key factors are maintenance discipline, driving conditions, and timely attention to wear items such as the engine oil, transmission fluid, cooling system, and suspension components. For prospective buyers, a detailed service history and a professional inspection are essential to gauge how much life remains in a specific vehicle.
Is the 2009 Acura MDX reliable?
The 2009 Acura MDX is generally considered a reliable luxury SUV, particularly when it comes to its core components like the engine and transmission. However, common issues can arise, most notably the timing belt requiring replacement around 100,000 miles and potential electrical problems, though some of the latter can be resolved with simpler fixes than replacement. It is important to note that while some reliability reports for later models in this generation were mixed, the 2009 model year is often highlighted for its solid performance.

Common reliability concerns
- Timing belt: The 2009 MDX has an interference engine with a timing belt that requires replacement every 105,000 miles to prevent catastrophic engine damage. It's crucial to check if this service has been done, as a broken timing belt can destroy the engine.
- Electrical issues:
- Bluetooth module: A faulty Bluetooth module can drain the battery. A simple and often recommended fix is to disconnect the module rather than replacing it, as it can be expensive and prone to repeat failure.
- Seat controls: The power seat control panel can disconnect from its switches due to a broken plastic piece. This is often repairable with a product like JB Weld.
- Transmission: While generally solid, some owners report harsh shifting. Flushing the transmission fluid, especially with OEM Honda fluid, can often resolve this problem. A check engine or D4 light flashing can indicate a failed torque converter clutch.
- Oil consumption: The 2009 model is not affected by the oil burning issue that plagues later models (2010-2013).
- Rust: Rust can appear where the door gasket meets the body, on the front edge of the hood, and on the bottom of the doors.
What to keep in mind
- Maintenance is key: Like any vehicle, regular maintenance, including timely fluid changes and other factory-recommended services, is critical for the longevity of the MDX.
- Fuel economy: This is not a fuel-efficient vehicle, and it requires premium gasoline.
- Pricey repairs: The luxury features on the MDX can lead to expensive repairs if something goes wrong with those specific components, so consider a good extended warranty if you are concerned.
