Bummer about the BCM. It's not Honda's fault, it's covid's fault. Likely an issue to get a new BCM with any vehicle brand at this time.

 

[beww]

Junkyard?
Perhaps as an interim measure?

 

[TheDarkKnight]

The part being back ordered till end of march is just nature of the beast right now. Pretty much every model has something that is backordered, friend at dealer has cars sitting for months .

i havent read anything on bcm failures but u can ask honda to discount the part or service for the delay.

Spot on.

And should be further noted that component part delays etc are affecting pretty much all car manufacturers, not just Honda 👍

And it's not just cars. Supply chains are in chaos.

This is the prime sort of situation where you check your local Pick-a-Part yards for new CR-V's every day until one shows up and you swoop in and snatch it. Even if the dealer won't install it, it certainly sounds very DIY-able.

They are indeed.
The problem is it also makes a convenient excuse, and it can be hard to tell the difference.
@sirwired's suggestions seems viable, at least worth a try.

Most wrecking yards normally will search their online sources to help find the part at another yard for you.

Yep.

The entire world has largely moved to "just in time" lean supply chains, where they do not hold much if any inventory and it is all moved world wide in a continuous supply stream. The goal is to eliminate warehouse storage of parts and other supplies and hold only short term quantities locally and rely on daily or weekly batch deliveries. The world shipping routes ARE the new modern warehouses for production.

We now know what the affect on lean supply chains is when anything at all (labor, materials, shipping, etc) impacts the smooth flow of supplies. And like any engine that has an issue and shuts down or goes into limp mode... you cannot restart the supply chains free of pain. It can take more than a year to get things smoothed out in today's lean supply chains.

Coming up on 4 months and Honda North America and the Dealership still have no idea when the part will arrive. This is crazy, living my life disconnecting the battery every time I am not using the vehicle. Since the Keyless Access Control Unit is no longer under warranty, Honda of North America has offered to pay for 1/2 of the repair costs for my "Troubles."

Just want to say sorry to hear of all the problems your vehicle is giving you. I also want to say thank you for keeping us informed. Hopefully your vehicle will be fixed ASAP and your information may help another member on this forum.

This would be a good time to remind new owners to avail themselves of a Honda Care warranty. Not necessarily when you buy the car as the price can be prohibitive, but you can get a reasonable one online from a dealer later.

Note, I never bought one on any of my cars before.

About 3 weeks ago we were out of town CRV in garage at home 2 1/2 days. We got back battery was DEAD. I started to charge, heard horn trying sound, so I’m thinking alarm went off and never stopped. After charge up I drove around a couple miles no problems. Into garage and turned off. 20 minutes later alarm going off, had to get key out of fob to unlock door, alarm stopped. I took to Honda dealer who couldn’t find any reason for drain. Said that alarm issue could point to BCM. I didn’t leave it at dealer at that point. Probably should have. A day or two later alarm went off again in the garage, something less than an hour. Again battery dead. Charged back up, took back to dealer. He was going to replace BCM. Turns out it is on back order. Now, after turn car off, I hear a bunch of clicks and it starts up to accessory mode. And red light blinks (immobilized?). Internet search says BCM has been discontinued, replacement is also on back order. Anybody else trying to live through this issue? How? Manual switch to deenergize ignition circuit? I am extremely frustrated.

Original battery? If so, I’d be tempted to replace that before doing anything else.

First step, especially considering the age of your vehicle and if it is still the original battery: Have the battery properly charged and load tested.

I would not be going after the BCM, or other "solutions" until you have ruled out the battery as cause.

Yes, a battery can be killed off by some system that will not power down, but it is not the first suspect where modern CRVs are concerned.

Batteries, in general, do not last as long as in the "old days" because modern vehicles put a lot of low level stress on flooded cell starter batteries due to normal parasitic drain from all the various electronic systems in the vehicle. Yes, they all get powered down when you stop the engine, but they still draw a small amount of standby power. Normal parasitic drain on a gen5 CRV is 40-50ma. If you do the math, you will see that a fully charged and healthy battery can be completely drained (51R battery) in 30-40 days sitting. But the fact is, even partial discharge in any persistence leads to early battery failure due to plate sulfation. Unless you keep a battery above 90% of full charge, sulfation of the plates is an issue that accelerates as discharge continues over time.

Merged to existing thread covering same issues

 

[jaymigs]

I'm having the same exact issues with my 2017 EX-L. I have to disconnect and reconnect the battery whenever I drive my car. I also find myself unable to stop the engine at times due to the controls spazzing out. It takes a few minutes for the button to finally work and stop the engine. Reached out to my dealer for an update and they still have no ETA at all on when the part will arrive. Just wondering if you've had any progress with your car, Jtpeter. It's a sucky situation to be in.

 

[Grpass]

Has anyone tried a used one from Ebay or a wrecking yard? Curious if they work OK.

Well, I had just about decided to replace the battery even though it tested as good. With the accessory mode on the maintaining charge (800 mA) it was still dead in the morning. Then I saw your posts suggesting replace battery. We did that this evening. Car has not gone into accessory mode yet, I have the maintainer charge on it anyway. We'll see what has happened with it in the morning.

I don't think we are out of the woods yet. So I have also reached out to an outfit that repairs all types of control modules. They maintain they can turn it around in 2-3 days and offer a lifetime warranty on it. Not sure I know what that warranty would mean. They also state it will be plug and play, so they must be able to program to VIN. Regardless, it is another possible action I can take while waiting who knows how long for a new module. Has anyone had any experience with repaired modules? I've read most of the posts and don't recall seeing anything on it.

I always cringe a little when someone says a battery "tested good".
It means it passed the specific tests performed, at that specific time and place.
But a battery is a complex electrical/mechanical/chemical device. Add to that the fact that it's being continuously beat around and feels every pothole, as well as having liquid sloshing around on every corner, and it's amazing to me they do as well as they do.
I have just got to the point where I do not ask a battery in a modern car to go through a third winter, no matter how it tests at the moment.
Granted, there is no track record for the 12-volt batteries in the hybrids, but I'll probably replace that after 2 seasons just out of habit.
The UK got their hybrids a year before us, but I don't think it ever gets cold enough there to be a real battery test.

This is exactly what is going with mine. Are you getting a "Keyless remote" display error?

Anyways I just got a call from the dealership 15 min ago. After 4 months, the Keyless Access Control Unit has arrived. Scheduled for Monday to install. Fingers crossed!
