Seeing B137 on your Acura’s display means an engine oil and filter change with a multi-point vehicle inspection is due, along with a tire rotation, a transmission fluid change (plus transfer fluid on AWD and SH-AWD) and a brake fluid replacement.
The letter and the numbers are read separately. “B” is the main service; every digit after it is an additional job tracked on its own clock. A code with several digits is not one big procedure — it is several unrelated services that happened to come due in the same week.
You are not limited to an Acura dealer for B137. The two brands share a parts network, which means a Honda service department can carry out the same work, and independent specialists familiar with the marque are usually cheaper again.
Acura B137 Service Cost
Budget $300 to $555 for the Acura B137 service. The spread reflects genuine differences in engine, fluid volume and shop rates rather than padding, and because B137 bundles separate jobs, an itemized quote tells you far more than a single figure.
| Item | What it covers | Typical cost |
|---|---|---|
| “B” | Oil and filter change, plus multi-point inspection | $90 – $180 |
| “1” | Tire rotation | $30 – $45 |
| “3” | Transmission fluid (and transfer fluid on AWD/SH-AWD) | $100 – $200 |
| “7” | Brake fluid | $80 – $130 |
| Total Acura B137 service | $300 – $555 | |
| Doing it yourself (parts only) | around $165 | |
Brake Fluid in B137 Runs on a Calendar, Not Your Odometer
Sub-item 7 is the odd one out in B137. Every other item counts down against how you drive; brake fluid counts down against time. Acura’s own guidance is explicit about it: if the Maintenance Minder has not asked for item 7 within 36 months of the last reset, replace the brake fluid anyway. Three years, whatever the mileage says.
The reason is that brake fluid is hygroscopic. It draws moisture out of the air through the reservoir and the flexible hoses, and water lowers the fluid’s boiling point. Fluid that boils under sustained braking turns to vapor, and vapor compresses in a way liquid does not. That is the long, soft pedal drivers describe on a long descent. A garage queen with 3,000 miles a year is no more exempt from this than a commuter car.
Acura specifies DOT 3, and the job is a genuine bleed at all four corners until clean fluid comes through — not a top-up of the reservoir. Old fluid is visibly darker than new, so it is one of the few services you can sanity-check yourself by looking. If a quote for B137 looks suspiciously cheap, confirm the brake line is a flush rather than a level check.
When Is the Acura B137 Service Due?
Mileage is the wrong way to think about it. Acura’s algorithm watches how the engine is actually used — operating temperature, trip duration, load, revolutions — and adjusts accordingly. Two identical cars can be thousands of miles apart when B137 appears, and both are correct.
The countdown is visible before it becomes urgent: a wrench symbol at 15% remaining oil life, a firmer message at 5%, and a negative distance readout once it passes zero telling you how far past due you now are.
Brake fluid is the exception inside B137. Acura runs it to a three-year calendar rather than a distance, so it can fall due on a car that has barely moved.
Which Acuras Display B137?
B137 is not model-specific. It can appear on the MDX, RDX, TLX, ILX, Integra, RLX, ZDX or TSX. What changes between them is the cost rather than the work: bigger engines take more oil, some require different fluids, and labor times vary with how accessible everything is.
Check your owner’s manual for the exact fluid specifications your engine needs before booking.
Is Acura B137 Service Free Under Complimentary Maintenance?
Partly at best. Acura’s program covers A1 and B1 work — oil, filter, tire rotation and inspection — for two years or 24,000 miles on 2023 and 2024 cars. For 2025 models it shrank to the first scheduled service inside 12 months or 12,000 miles. Everything in B137 beyond that basic scope is chargeable.
The practical move is to ask for an itemized invoice rather than a single number, because the oil and rotation line may still be covered while the rest is not. The work has to happen at a participating Acura dealer with Acura Genuine parts and oil, and the clock runs from the car’s original in-service date, not the day you bought it.
What B137 Means for SH-AWD Acuras
The B137 work itself is identical whether your Acura drives the front wheels or all four. What changes is what tends to arrive alongside it. Super Handling All-Wheel Drive uses a torque-vectoring rear unit that Honda does not fit to its own models, and it carries a fluid service of its own: sub-item 6, rear differential fluid, due at around 15,000 miles initially and every 30,000 miles after.
Sub-item 3 is also affected. On an SH-AWD car the transmission fluid change in B137 brings the transfer unit with it, which is a separate drain and fill and a separate labor line. A quote that looks high next to a front-wheel-drive Acura may be entirely legitimate.
So if you drive an SH-AWD MDX, RDX, TLX or ZDX, do not be surprised to see B137 arrive with a 6 attached. Front-drive Acuras never show a 6, because there is no rear differential to service.

Acura B137 Service FAQ
What does the Acura B137 code mean?
The “B” is an oil and filter change with a multi-point inspection, and each digit after it is a separate job that has come due at the same time. For B137 those are a tire rotation, a transmission fluid change (plus transfer fluid on AWD and SH-AWD), a brake fluid replacement. It is a bundle of independent services, not one procedure.
How much does the Acura B137 service cost?
Typically $300 to $555 at a dealer or independent shop, depending on your model and local labor rate. The breakdown by sub-item is in the table above. Acura and Honda dealer pricing is broadly comparable, so a Honda service department is worth a call for a second quote.
Can I do the Acura B137 service myself?
Partly. The oil and rotation are easy. A proper brake fluid flush needs bleeding at all four corners in the right sequence, and air left in the system gives you a soft pedal — it is doable at home with the right kit but it is not a beginner job. Parts alone come to roughly $165.
Is B137 covered by Acura complimentary maintenance?
Not fully. The program covers A1 and B1 services for two years or 24,000 miles on 2023 and 2024 cars, and only the first scheduled service within 12 months or 12,000 miles on 2025 models. B137 includes work beyond that, so expect the additional items to be chargeable. The oil and rotation portion may still be covered, so ask for an itemized invoice.
Does the B137 code mean something is wrong with my Acura?
No. B137 is a maintenance reminder shown with a wrench symbol, generated by the Maintenance Minder’s own countdown. It is not a diagnostic trouble code. A check engine light comes from a different system entirely and points to a stored fault. If both are showing they are unrelated, and the check engine light is the one to look at first.
How do I reset the B137 code?
An Acura dealer will reset it as part of the job. Doing it yourself: touchscreen models use Settings, then Vehicle, then Maintenance Reset, while older cars use the SEL/RESET stalk button or trip knob held for around ten seconds with the ignition on. On a multi-item code like B137 you can reset sub-items individually — do that rather than clearing everything, or the car will stop tracking jobs you have not actually done. Our Acura Maintenance Minder reset guide covers each method by model.
