Reviewed for service schedule clarity.
The 2024 Acura MDX AWD is powered by a 3.5L V6 (J35Y6) engine with Super Handling All-Wheel Drive (SH-AWD). Unlike older cars with fixed schedules, the MDX uses an intelligent Maintenance Minder system that calculates service needs based on your actual driving habits .
> ENGINE DESIGN NOTE: The 3.5L V6 uses a timing belt, not a chain. This is an interference engine. If the belt breaks at speed, the pistons will strike the valves, causing catastrophic engine damage. This is not a timing chain – replacement is mandatory .
Key Takeaways
- Follow the Maintenance Minder system, not fixed odometer intervals. The vehicle's computer monitors driving conditions and displays alphanumeric codes (A or B with subcodes 1-7) when specific services are due .
- The 3.5L V6 uses a timing belt, NOT a chain. Replacement is required when Code 4 appears (typically between 80,000-105,000 miles or 7-10 years) . If you regularly drive in very high temperatures (over 110°F), very low temperatures (under -20°F), or tow a trailer, replace every 60,000 miles .
- Brake fluid replacement is strictly time-sensitive. Independent of the Maintenance Minder, replace brake fluid every 3 years regardless of mileage .
- SH-AWD rear differential fluid replacement is critical. If you regularly drive in mountainous areas at very low speeds or tow a trailer, change differential fluid at 7,500 miles, then every 15,000 miles .
- If no service message appears within 12 months of reset, change the engine oil at least once per year .
- The 2024 MDX includes a complimentary Acura Maintenance Program covering 1 year or 12,000 miles of oil changes, tire rotations, and multi-point inspections.

SH-AWD Note: The SH-AWD system has a rear differential with clutches that require specific fluid (Acura AWD DPSF). This is NOT the same as the VTM-4 fluid used in older MDX models.
Understanding the Maintenance Minder System
The 2024 Acura MDX does not have a traditional fixed‑mileage maintenance schedule. Instead, Acura employs a Maintenance Minder system that monitors vehicle operating conditions and calculates when service is required .
How the System Works
When the engine oil life reaches 15%, a wrench symbol illuminates on the driver information interface, and the system displays alphanumeric codes indicating which services are due .
| Oil Life Remaining | Message Displayed | Recommended Action |
|---|---|---|
| 15% | SERVICE DUE SOON | Service should be scheduled soon |
| 5% | SERVICE DUE NOW | Maintenance should be performed immediately |
| 0% (Negative Distance) | SERVICE PAST DUE | Service is overdue – schedule immediately |
Oil Life Percentage Display
Based on engine operating conditions, the remaining engine oil life is calculated and displayed as a percentage :
| Displayed Oil Life (%) | Calculated Oil Life (%) |
|---|---|
| 100 | 100 to 91 |
| 90 | 90 to 81 |
| 80 | 80 to 71 |
| 70 | 70 to 61 |
| 60 | 60 to 51 |
| 50 | 50 to 41 |
| 40 | 40 to 31 |
| 30 | 30 to 21 |
| 20 | 20 to 16 |
| 15 | 15 to 11 |
| 10 | 10 to 6 |
| 5 | 5 to 1 |
| 0 | 0 |
Under normal driving conditions, oil changes typically occur between 7,500 and 10,000 miles. Severe conditions could trigger alerts in a range from 3,000-4,999 miles .
Viewing Maintenance Minder Information
To display Maintenance Minder information :
- Set the power mode to ON (do not start the engine)
- Press the right selector wheel until the content is displayed
- Rotate the right selector wheel until the Maintenance screen appears
- The oil life percentage and due maintenance codes will display on the driver information interface
Maintenance Minder Codes
The Maintenance Minder communicates service needs through alphanumeric codes. A code consists of a main item (A or B) optionally followed by sub‑item numbers (1 through 7) .
Main Item Codes (A, B)
| Code | Required Service |
|---|---|
| A | Replace engine oil |
| B | Replace engine oil and oil filter; inspect front and rear brakes; check parking brake adjustment; inspect tie rod ends, steering gearbox, and boots; inspect suspension components; inspect driveshaft boots; inspect brake hoses and lines (including ABS/VSA); inspect all fluid levels and condition of fluids; inspect exhaust system; inspect fuel lines and connections |

Reset Procedure :
- Set the power mode to ON (do not start the engine)
- Press the right selector wheel until the content is displayed
- Rotate the right selector wheel until the Maintenance screen is displayed
- Press and hold the right selector wheel for about 10 seconds to enter the reset mode
- Rotate the right selector wheel to select a maintenance item to reset, or to select All due items
- Press the right selector wheel to reset the selected item
- Repeat for other items you wish to reset
Monthly & Pre-Drive Checks
As outlined in the 2024 MDX Owner's Manual, perform these checks regularly :
| Frequency | Check Item |
|---|---|
| Monthly | Brake/Clutch fluid level |
| Monthly | Tire pressure (including spare); examine tread for wear and foreign objects |
| Monthly | Exterior lights operation |
| Every 6 months | Wiper blade condition |
| Pre-drive / Before long trips | Engine oil level; windshield washer fluid; tires for damage; fluid leaks under vehicle |
Engine Oil Change Guidance
Factory Requirements
| Specification | Detail |
|---|---|
| Recommended oil | SAE 0W‑20 premium-grade synthetic oil with API Certification Seal |
| Oil change trigger | Maintenance Minder code A or B (when oil life reaches 15%) |
| Maximum time interval | If no service indicated within 12 months, change oil at least once per year |
| Oil filter | Replace at every oil change (code B includes filter change) |
Typical Mileage Expectations
| Driving Style | Expected Interval |
|---|---|
| Normal (highway/city mix) | 7,500-10,000 miles |
| Severe conditions (short trips, city traffic, towing) | 3,000-4,999 miles |
How to Check Engine Oil Level
Check the engine oil level every time you fill the fuel tank :
- Park on level ground and wait at least 3 minutes after engine shutdown
- Pull out the dipstick and wipe completely clean
- Reinsert fully, then remove again
- Oil level should be between the upper and lower marks
Timing Belt – The Most Critical Service
The J35Y6 V6 engine requires timing belt replacement on a strict schedule. This is the single most important maintenance item for the 2024 MDX AWD .
| Specification | Detail |
|---|---|
| Engine type | Interference engine |
| Replacement trigger | Maintenance Minder code 4 |
| Standard replacement | When Code 4 appears, typically 80,000-105,000 miles or 7-10 years |
| Severe condition interval | If driving regularly in very high temperatures (over 110°F), very low temperatures (under -20°F), or towing: replace every 60,000 miles |
| Water pump | Replace with timing belt (inspect water pump) |
Why Timing Belt Replacement Is Critical
The J35Y6 engine is an interference engine. If the timing belt breaks, the pistons will strike the valves, resulting in bent valves, damaged pistons, and typically requiring complete engine replacement . As one specialist explains, *"a worn or broken timing belt can lead to costly engine damage"* .
Owner Guidance for Timing Belt Service
When replacing the timing belt, replace these components simultaneously due to overlapping labor:
- Timing belt itself
- Timing belt tensioner
- Water pump (driven by the timing belt; replacing together saves labor)
- Drive belts (serpentine belt)
- Engine coolant (requires draining to replace water pump)
- Spark plugs (Code 4 includes spark plug replacement)
- Valve clearance inspection (adjust only if noisy)
Engine Coolant Service
| Specification | Detail |
|---|---|
| Replacement trigger | Maintenance Minder code 5 |
| Coolant type | Acura Long Life Antifreeze/Coolant Type 2 (premixed 50/50, blue) |
| Typical interval | Approximately 60,000-120,000 miles |
Owner Guidance: Do not use generic green coolant. Honda/Acura Type 2 coolant is specifically formulated for aluminum engine components. If the coolant appears dark or contaminated, replace it sooner regardless of the Maintenance Minder.
Brake Fluid Replacement
| Specification | Detail |
|---|---|
| Specified fluid | Acura Heavy Duty Brake Fluid DOT 3 |
| Replacement trigger | Maintenance Minder code 7, or if no code 7 appears within 36 months after reset, replace brake fluid every 3 years |
| Check frequency | Monthly |
| Temporary substitute | DOT 3 or DOT 4 from a sealed container |
| DOT 5 warning | NOT compatible – never use DOT 5 fluid (silicone-based) |
Why it's critical: Brake fluid is hygroscopic – it absorbs moisture from the air over time. This moisture lowers the fluid's boiling point (potential brake fade under hard braking) and promotes internal corrosion of the brake system.
Owner Guidance: A complete system flush (draining old fluid from each caliper) is required. Topping off the reservoir is not sufficient. Flush intervals: every 3 years regardless of mileage .
Transmission & Transfer Case Service (10-Speed Automatic)
The 2024 MDX is equipped with a 10-speed automatic transmission (10AT) .
| Specification | Detail |
|---|---|
| Specified fluid | Acura ATF Type 2.0 |
| Replacement trigger | Maintenance Minder code 3 |
| Standard interval | Approximately 60,000 miles |
| Severe condition interval | If regularly driving in mountainous areas at very low speeds or towing: change more frequently |
| Transfer case fluid | Replace with transmission fluid (same service, code 3) |
Critical Warning: Using any transmission fluid other than Acura ATF Type 2.0 can damage the transmission .
Owner Guidance: The proper method for a complete fluid exchange is the "3x method" (drain, fill, drive through all gears, repeat three times). This is the dealer-recommended procedure and does not use a power flush machine.
SH-AWD Rear Differential Service (AWD-Specific)
The SH-AWD (Super Handling-All Wheel Drive) system has a rear differential with clutches that require specific fluid and regular maintenance. This is critical for AWD models only .
| Specification | Detail |
|---|---|
| Replacement trigger | Maintenance Minder code 6 |
| Fluid type | Acura AWD DPSF (Dual Pump System Fluid) |
| Standard interval | Approximately 30,000-45,000 miles |
| Severe condition interval | 7,500 miles, then every 15,000 miles |
Severe Condition Requirement – Important Note
From the 2024 MDX Owner's Manual :
> *"Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km)."*
This applies to many MDX owners who:
- Live in mountainous regions (Rockies, Appalachians, West Coast ranges)
- Regularly tow trailers, boats, or campers (up to 5,000 lbs)
- Frequently drive on steep, winding roads
- Use the MDX for heavy-duty family hauling with frequent AWD engagement
Fluid Warning: Use only Acura AWD DPSF (Dual Pump System Fluid). Do not use VTM-4 fluid or standard gear oil—these will damage the SH-AWD clutches .
Drive Belt & Air Filters
| Component | Replacement Trigger | Severe Conditions Note |
|---|---|---|
| Engine air cleaner element | Maintenance Minder code 2 | If you drive in dusty conditions, replace every 15,000 miles (24,000 km) |
| Cabin air filter (dust and pollen filter) | Maintenance Minder code 2 | If you drive in urban areas with high soot concentrations, replace every 15,000 miles (24,000 km) |
| Drive belt | Maintenance Minder code 2 (inspect drive belt) | Replace if cracked, frayed, or glazed; typically during timing belt service |
Owner Guidance: Both filters are inexpensive and can be replaced without special tools. The cabin air filter is typically located behind the glove box; replacing it annually improves interior air quality and HVAC performance.
Valve Clearance Inspection
| Specification | Detail |
|---|---|
| Inspection trigger | Maintenance Minder code 4 (timing belt service) |
| Adjustment | Adjust the valves only if they are noisy during services A, B, 1, 2, or 3 |
Owner Guidance: The J35Y6 engine uses mechanical lifters (not hydraulic), so valves can go out of adjustment over time. Exhaust valves tend to tighten and may not make noise even when dangerously tight. While the manual says "adjust only if noisy," many Acura specialists recommend checking clearances at the 80,000-120,000 mile mark regardless.
Severe Driving Conditions Summary
The following severe condition requirements are explicitly stated in the 2024 MDX Owner's Manual for AWD models :
| Condition | Component | Required Action |
|---|---|---|
| Mountain driving at very low speeds or towing (5,000 lbs capacity) | Rear differential fluid (SH-AWD) | Change at 7,500 miles, then every 15,000 miles |
| Mountain driving at very low speeds or towing | Transmission fluid | Change more frequently (25,000-30,000 miles recommended) |
| Regular driving in very high temperatures (over 110°F/43°C) | Timing belt | Replace every 60,000 miles |
| Regular driving in very low temperatures (under -20°F/-29°C) | Timing belt | Replace every 60,000 miles |
| Trailer towing | Timing belt | Replace every 60,000 miles |
| Dusty driving conditions | Engine air cleaner element | Replace every 15,000 miles (24,000 km) |
| High-soot urban driving | Cabin air filter | Replace every 15,000 miles (24,000 km) |
| No service message for 12 months | Engine oil | Change at least once per year |
| Every 3 years (independent of Minder) | Brake fluid | Replace regardless of mileage |

| Engine coolant | When Code 5 appears (approximately 60,000-120,000 miles) | 5 |
| Brake fluid | Every 3 years (time-based, independent of codes) | 7 |
AWD vs. 2WD Maintenance Differences
| Maintenance Item | AWD (SH-AWD) | 2WD (Front-Wheel Drive) |
|---|---|---|
| Rear differential fluid | Required (Code 6) – use Acura AWD DPSF | NOT REQUIRED – no rear differential |
| Transfer case fluid | Required – use Acura ATF Type 2.0 | Not applicable (FWD only) |
| Drivetrain inspections | Inspect driveshaft boots (B service) | Driveshaft boots only (FWD) |
Acura Maintenance Program (1 Year / 12,000 Miles)
The 2024 MDX includes a complimentary Acura Maintenance Program that covers:
- Engine oil and engine oil filter changes (with Acura Genuine Oil)
- Tire rotations
- Multi‑point inspections
The program covers the first year or 12,000 miles, whichever comes first, and is valid only when performed at a participating Acura dealership .
Long-Term Ownership Summary
- The timing belt is not negotiable. The J35Y6 engine will self-destruct if the belt breaks. Replace when Code 4 appears (80,000-105,000 miles or 7-10 years, whichever comes first) . The water pump should always be replaced at the same time .
- Follow the Maintenance Minder, but respect time-based intervals. The system adapts to your driving habits. However, note that brake fluid is due every 3 years regardless of what the Maintenance Minder shows .
- SH-AWD is a major maintenance consideration for AWD models. If you live in mountainous areas or tow, follow the 7,500/15,000-mile severe schedule for differential fluid .
- Use Acura-specified fluids:
- Transmission: Acura ATF Type 2.0
- Rear differential: Acura AWD DPSF only (not VTM-4)
- Coolant: Honda Type 2 blue only
- Brake fluid: Honda DOT 3 only
- Engine oil: SAE 0W-20 synthetic
- The 2024 MDX can tow up to 5,000 lbs when properly equipped. If you tow regularly, follow the severe service intervals for all components .
- Keep maintenance records. Save all receipts as proof of completion, especially for the timing belt service. These records add value if you sell the vehicle.
- Acura warranty coverage includes: Basic: 4 years / 50,000 miles; Powertrain: 6 years / 70,000 miles.
- The 2024 MDX Owner's Manual is the final authority. All information in this guide is derived from the official 2024 Acura MDX Owner's Manual. If there is a discrepancy between this guide and your vehicle's MID, follow the vehicle.
