I've got a 2017 MDX that I bought several months ago and just encountered this message on the dashboard last night. It sounds like just a reminder for routine scheduled maintenance, but just wanted to be sure that it's not indicative of any specific issue that was detected.

I read somewhere online that the B13 service includes the following:

  • Oil and oil filter change.
  • Transmission fluid flush
  • Front transfer case oil change
  • Tire rotation
  • Routine checks for brake and belt wear, axle boots, fuel and brake lines, exhaust, and a general inspection for any issues.
Does this sound accurate? I'd rather not take it in to the Acura dealership for this service because I know they're going to charge a premium for these things especially since I can get the oil/filter changed anywhere and I just got new tires so I don't need the rotation. Any remaining items I could surely have done by any competent mechanic shop.

All service codes are displayed when the oil change is due at around 8000-9500 miles intervals under normal driving conditions. It is usually a single letter followed by a single or multiple number(s) for the type of service due. Changing the brake fluid every 3-4 years, wipers blades, or tire balance/alignment maintenance items do not have a maintenance code.

I purchase my own engine oil from Walmart (Mobil 1 full syn for $27) to take. I use their oil filter and labor to change out for about $31. I have lifetime rotation/balance at Discount Tires and do that every oil change. I also purchase my cabin/engine air filters on-line and it takes a few minutes to change them out for under $35 for both. I also have lifetime alignment at Firestone and double-check the alignment if I have:
  • new tires
  • suspension or brake work done
  • if I hit anything hard when driving/parking like a pothole or concrete stopper when parking
  • when I have a big trip planned and I haven't checked in a year.

I let Acura do the "3" service 100% because Acura/Honda transmission can be very sensitive and even fail if you use the wrong transmission fluid type or change the fluid out incorrectly. My dealership does either a 1X gravity drain and refill or 3X gravity drain, refill, run transmission through the gears and repeat 2 more times (3X exchanges more fluid). DO NOT do any transmission service that exchanges 100% of the fluid or suck out trans fluid as part of their service if you go with a local shop. The MDX transmission will drive +200,000 miles trouble free with Honda/Acura ATF and doing the 1X or 3X method every 30,000-60,000 miles.

Acura Service Codes:

Main CodeDescription

Here is the listing of the maintenance codes.
