How Acura schedules service: Maintenance Minder

Acura's Maintenance Minder calculates oil life from real engine conditions and shows service codes instead of fixed mileages — code A or B (oil / oil + inspection) plus sub-codes for items like tire rotation (1), air filters (2), or transmission fluid (3). Follow the codes, not the calendar. One interval you should never stretch: most Acura 3.5L V6 engines (MDX, TL) use a timing belt with a roughly 105,000-mile / 7-year replacement — a snapped belt on this interference engine means bent valves. SH-AWD models add a rear-differential fluid service that's essential for the torque-vectoring unit.

SERVICE BRAKES, HYDRAULIC:PEDALS AND LINKAGES

Campaign #25V391000 · Dec 6, 2025

Issue: Honda (American Honda Motor Co.) is recalling certain 2021-2025 Acura TLX, 2023-2025 Acura MDX, and 2023-2025 Honda Pilot vehicles. The brake pedal pivot pin was not secured properly, which can cause the pedal to shift out of position. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard numbers 108, "Lamps, Reflective Devices, and Associated Equipment" and 135, "Light Vehicle Brake Systems."

Risk: A brake pedal that shifts out of position can prevent the driver from applying the brakes as intended, increasing the risk of a crash or injury.

Fix: Dealers will inspect and replace the brake pedal assembly as necessary, free of charge. Owner notification letters were mailed July 29, 2025. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numbers for this recall are FLX and XLY.

AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION:FRONT PASSENGER

Campaign #26V332000 · May 21, 2026

Issue: Honda (American Honda Motor Co.) is recalling certain 2018-2021, 2023 Acura TLX, 2019-2024 RDX, 2017-2020, 2022-2026 MDX, 2017-2021, 2023, 2025 Honda Ridgeline, 2017-2022 Pilot, 2019-2021 Passport, 2018-2026 Odyssey, 2019-2022 Insight, 2019-2021 HR-V, 2018-2020 Fit, 2020-2022 CR-V Hybrid, 2017-2022 CR-V, 2017-2018, 2021 Civic Type R, 2017-2021 Civic hatchback, 2016-2020 Civic coupe, 2016-2022 Civic, 2017-2022 Accord Hybrid, and 2016-2022 Accord vehicles. The front passenger seat weight sensor may crack and short circuit, which can cause the air bags to deploy unintentionally during a crash.

Risk: Air bags that deploy unintentionally during a crash increase the risk of injury.

Fix: Dealers will replace the seat weight sensors, free of charge. Owner notification letters were mailed July 7, 2026. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numbers for this recall are BOL, WO9, OOA, WOM, XOH, NOC, POD, BOE, UOF, POB, EOG, AOI, QO8, TOJ, DO7, and SOK. This recall expands previous NHTSA recall number 24V064. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning May 29, 2026.

Recall data refreshed Jul 19, 2026.

Essential maintenance

Critical for safety and preventing major damage

🛢️

Oil & Filter (Maintenance Minder A/B)

Every 8,000 mi

Change when the Maintenance Minder reaches 15% oil life or shows code A/B — typically every 7,500-10,000 miles with 0W-20 synthetic. Short-trip city driving triggers the code sooner; that's the algorithm doing its job.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

⏱️

Timing Belt (3.5L V6 — MDX, TL)

Every 105,000 mi

J-series V6: replace the timing belt around 105,000 miles or 7 years (Maintenance Minder sub-code 4). It's an interference engine — a failed belt destroys valves. Replace the water pump and tensioner in the same job. (2022+ MDX 3.5L remains belt-driven; the Integra's turbo four is chain-driven.)

Estimated cost — typical U.S. ranges

Dealer

~$935–$1175

Shop

~$655–$825

DIY

Pro only

On interference engines, a snapped belt destroys valves. Worth doing on schedule. Bundle water pump + tensioner — labor is already there.

🔄

Tire Rotation (Sub-code 1)

Every 7,500 mi

Rotate when sub-code 1 appears — roughly every 7,500 miles. SH-AWD models: keep tread depths matched across all four corners.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

🛑

Brake Inspection

Every 10,000 mi

Inspect pads, rotors, and fluid level with every A/B service. Type S models with Brembo front calipers: pads wear faster and cost more — budget ahead.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

🧪

Brake Fluid

Every 30,000 mi

Replace every 3 years regardless of mileage — Honda/Acura schedules this on time because the fluid absorbs moisture.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

⚙️

Transmission Fluid (Sub-code 3)

Every 30,000 mi

Replace ATF when sub-code 3 appears — commonly every 30,000-60,000 miles depending on duty. Use Honda/Acura ATF only (DW-1, or the 10-speed's specified fluid); aftermarket 'universal' ATF causes shudder in these gearboxes.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

🔧

SH-AWD Rear Differential Fluid

Every 30,000 mi

SH-AWD (MDX, TLX, RDX): replace the rear differential fluid roughly every 30,000 miles (sub-code 6) — the torque-vectoring clutch packs run in this fluid, and whining or binding in tight turns is the classic overdue symptom.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

⚡

Spark Plugs (Sub-code 4)

Every 100,000 mi

Iridium plugs around 100,000 miles on most models. Turbocharged Integra/ADX engines: check the manual — forced induction typically shortens the interval.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

💨

Engine Air Filter (Sub-code 2)

Every 30,000 mi

Replace with sub-code 2, roughly every 30,000 miles — sooner in dusty conditions.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Recommended maintenance

Extends the life of your vehicle and improves comfort

🌬️

Cabin Air Filter (Sub-code 2)

Every 30,000 mi

Replace with sub-code 2 alongside the engine air filter. Behind the glovebox — an easy DIY on most Acuras.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

🌡️

Coolant Replacement (Sub-code 5)

Every 100,000 mi

Honda/Acura Type 2 coolant: first change around 10 years / 100,000 miles, then every 5 years / 50,000. Use the blue Type 2 coolant only.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
