Code popped up this week on my 2014 RDX with 308,000+ miles.
I do not recall at what mileage the previous timing belt, spark plugs service was done. The local shop where I got it done is closed and I can't find my records for that service.
I am thinking it is not 105,000 miles ago. How does the car know when it is due? Computer in the car? I have no issues that should require new spark plugs either.
I replace the filters and they look fine to me despite getting code for it.
I checked the brake fluid and it is getting dark. but no code for it.
It has been at least two years since the last coolant flush. Again, no code for it.
Thanks.

Honda does not have such codes, how did you read this code?
Give me your VIN number and I'll take a look at the car history.

look here for Acura service codes https://www.motorcarsacura.com/acura-service-codes/

It looks like it's maintenance minder service codes. Some of the maintenance is based on an algorithm that monitors your driving; others are based on mileage. The one i would be concerned about is the timing chain only because you don't know when it was last done. If it was 105k miles, you are way overdue. If it was 210k miles, you may have a little time.

Alex Medeiros

Ditto. That's something that I wouldn't take a chance on.

altair47

ahh, this is how many services. Incredible)

I cannot help but ask what this might mean in English. Inquiring minds want to know!

This is in the sense that I, with my 170k miles, have never seen 5 services at once at the same time and I thought it was some kind of DTC code. I'm very surprised.
I can explain in Russian)

So if you're relaying that code correctly, you are doing a full "B" service (engine oil + filter, full inspection) plus:
- Rotating tires
- Replacing your air filters
- Replacing trans fluid
- Doing the 105k service, which includes timing belt, tb tensioner, tb pulleys, replacing your water pump, (during which you should replace your coolant as well), replacing the spark plugs, and a potential valve adjustment (if needed).
- Replacing diff fluid, assuming you're AWD.

In my opinion, it looks more intimidating than it actually is. You're essentially replacing all fluids and filters, in addition to your 105k service (B4 service). To your point, you can probably pass over various things like the air filters and certain fluids depending on their condition. If a fluid or filter looks dirty, you ought to change it. The computer only uses mileage intervals to suggest when things needs to be changed, as others have said. Unfortunately it does not account for the actual state of any fluids or parts.

If you're going to do the 105k service, your coolant typically gets replaced at this time, since the water pump comes off. This would also be an optimal time to replace your thermostat (if its original) since the coolant is drained, but that's up to you.

I'd suggest an Aisin kit for the timing belt and water pump - great success across Acuras on the forums here, can save money over paying a premium for parts at the stealership. The kit includes everything you need for the service, minus spark plugs and coolant. You can get the spark plugs pretty much anywhere, and just make sure to get OEM honda type 2 coolant. https://www.rockauto.com/en/moreinfo...=16088&jsn=876

As for spark plugs, I think NGK laser iridium is the go-to brand across all models, but hopefully someone else can chime in to confirm or deny that claim.

Lastly, unless you're seeing any performance issues, a valve adjustment can be subjective. Further if you're experiencing valve noise, or maybe you want to replace the valve cover gaskets to stop an oil leak, yeah getting one at this time would be beneficial. Otherwise it's up to you. If they've gone that entire 300k+ without being adjusted, I'd maybe look into it just for fun.

Good luck!

My bad gentlemen. I was not clear. I know what these codes mean. I was just wondering how they appear despite the intervals not being correct. For example, the timing belt to be replaced at 105K or 100K despite my previous replacement was not that many miles ago.
In any case, I got estimate from the always generous and reasonable stealership for the work to be done.

Timing belt $1100
Spark plugs $525
Transmission & transfer case fluid $250
Rear differential fluid $120
Engine & Cabin filters $120 (I always do this myself for $20 parts)

I am going to do the spark plugs myself.

Write the VIN number and I will look at the Carfax when the timing belt work is done

TheSauceBoss

If you have the competency to do the spark plugs yourself, I'd venture to say you could also do the trans and diff fluids yourself pretty easily as well. Just my opinion though. All you really need is a funnel and a bucket for the trans fluid, and a fluid pump (like $20 at meijer or walmart) for the diff fluid. Timing belt job sounds a lil pricy.... especially if spark plugs aren't included. Local honda and acura dealerships around me regularly send me coupons for a $650 timing belt job, for reference (parts included, minus water pump). Further, if you provide them the parts, you might be able to talk to them and work out something reasonable.

308,000 miles?? That's barely broken in!!

altair47

I do not think so

chilly731

308,000 miles...that gives me hope about the longevity of mine! Purely out of curiosity, a bit of a sidetrack here, what gas grade have you been using in your years of owning this car (87, 89, or 91, etc?)?

egads

The algorithm does oil life, the rest is based on how many oil changes you have had. That is based on the old 7500 mile oil change interval.
So: at the fourth oil change you get codes for 30,000 mile items (filters, trans fluid)
At the 14th oil change you get stuff for the 105k service.
There is almost never a need to replace Honda coolant before the 105k service. It was even 120k when there was a mileage based service chart in the owner's manual.
But of course you would go ahead and change it with the water pump at 105k. (that said, apparently those that live in the frozen north do change theirs more often)
Using the real thing is important because it does last that long and you don't "flush" out coolant in a Honda engine. Some old fluid will remain. Best to mix the same thing in there.

Brake fluid is every three years regardless of miles.

87 all the way. I am cheap.

wallmike

310,000+ today after a round trip to California.

I called an Acura dealer while driving through Vegas from Irvine. Asked what they charge for transmission & transfer case fluid service. $360. WTF?! I said dealer in Denver is $110 less. "This is our price" he said. F U Acura dealers. ALL of you.

MinnesotaRDX

I think you might have the most miles of any 2G RDX I've heard of. Awesome to see they're capable of 300k+. Have you had to make any repairs outside of typical maintenance?

This thread gives me hope. I'm never worried about the vehicle itself, or the engine, but the transmission scares the hell out of me. None of the Japanese companies know how to make a damn decent transmission.

chilly731

310,000+ miles and used 87 gas throughout the car's life. This thread needs to be shown to all those "premium vs regular gas" debate threads, to settle the topic once and for all.

egads

Change the fluid every 30k at least and every other oil change if you want to be prudent. (Normal 1/3 drain & fill)

altair47

I agree, this transmission is also not expensive at all and replacement(7-10hr labor) along with a good used transmission(40-80K milles) will cost about $2K, very very cheap.

TheSauceBoss

Like most things in life - if you take care of it, it will last. I'm not saying that some Honda transmissions aren't inherently flawed, but these forums are a goldmine for finding people who have prolonged the life of said inherently flawed transmissions. Plenty of people pushing 300k, 400k on 2G and 3G TL 5ATs, through both routine and specified maintenance. I think the problem lies in the fact that the majority of owners don't focus too much on trans fluid changes, pressure switch replacement, filter replacement, etc. Some of these transmissions will definitely make you pay for missing fluid changes. (Though the 2G RDX transmission seems to be more robust than most Honda trans) But since you've been part of the forums, I'm sure you're already ahead of the game with what your vehicle needs, and you'll do fine.
