Is this the original battery?

Yes, it is the original battery. I went in for service just under a month ago at Honda and the battery was still in good shape.

I'm going to go with "coincidence in timing" here on this one rather than your bumper incident being the cause.

If you had damaged anything such that it did not power down correctly when the vehicle is stopped, you would have persistent alert lights on your instrument panel. There really should not be anything in the front bumper that could cause a parasitic drain, unless perhaps you had aftermarket parking sensors added to the front bumper (assuming any and all lights in the bumper still work as intended).

As this is the original battery, even though Honda dealership recently tested the battery, I would get it retested at a local auto parts store, or use a home hand held tester. Generally the Honda dealership tests are pretty good, but nothing is certain where aged starter batteries are concerned.

If in doubt though, when you have the bumper restored, also have the dealer perform a test for abnormal parasitic drain. But honestly, I would replace that 3 year old battery first before spending money on an abnormal parasitic test. 3 years is about the average useful life on a 51R starter battery before they begin to throw issues at the owner (usually when least expected).

I'm having the repair done at a local body shop so I will definitely ask them to test the battery. Additionally, is it possible I broke or loosened the hood latch sensor from a collision like this? (apparently that is a common cause for the alarm to go off) Below are pictures of when the bumper came off. I did push it back into place and it clicked in just fine but there is a huge dent on the driver side so I'm replacing the whole thing.

Ouch... Smacked it pretty hard I can see. Usually, they just crumple and dent in some, but I can see you smacked it hard enough to actually tear into the bumper plastic, so yeah total replacement required.

The hood latch sensor is probably fine, but since it has to have a wired connection it is possible that wiring somewhere got yanked when the bumper came loose. I'm not sure how they route the wiring for the hood latch sensor, so it is worth investigating.

I can't tell from the photos if you have fog lights in the lower bumper, but if so that could be a point of failure due to shorted wires from the damage event.

Last thing to note is that the front facing got pulled forward and off as well, and the radar array is right behind that. But the only issue I would expect from that would be persistent HondaSensing alert failure lights. It does not look like damage would have tweaked the radar array (the little black plastic square just behind and below the Honda logo).

Could still just be coincident issues, and not actually related, but until everything gets repaired and the battery double checked, hard to tell.

Good luck with speedy and effective repair.

A few weeks ago my 2018 CR-V Touring was parked in the garage and the car alarm kept going off. The only way to stop it was to use the key inside the FOB to open the door and then start the car. The next day my car was dead. Replaced the battery and all was fine for 2 weeks then the same thing happened. But the alarm only went off once and my car was dead the next morning. Charged the battery & took it to the dealership. Asked them to check the alternator and see if I got a bad battery. After running a diagnostics, they told me my DCM microchip was bad and of course they need to order it. Thankfully I have the extended warranty! For such a newer model car I am surprised to be having this kind of issue. Has anyone else had this problem? My warranty is almost up and wondering if I should get out of it now if this is a foreshadowing of things to come?

Good question that has no answer. Darned if you do -- darned if you don't.

The bumper got replaced and the sensors and everything have been working just fine, the fog lights work too. The mechanic said the battery seems fine as well. But the random alarm/battery drain is still happening. I forgot to ask him to take a look at the hood latch sensor. I'm thinking I should take it to my Honda dealer to have it checked out. Although I worry they'll charge me a ton just to look at it. I'm really hoping it's a simple and quick fix.

Has anyone checked to see if any codes are present? Its easy to check.

I don't think anyone checked for codes to be honest. Can codes be present even with no warnings on the dash?

With all the electronics on today's cars, something is obviously having an issue in your car. Easy and free to check for codes. If you do it at an auto parts store they can also do a load test on your battery.

Hey everyone just want to share my experience I have been having with my 2020 CRV touring, long story short in the fall I could not turn it off ( on the dash it was keyless start system problem) so I took it to the dealer and they determined it was the start/stop switch so they replaced it, so I’m February it happened again so i took it back to the dealer and now this time they say it’s the body control module, and this part is on back order to be announced. I have been in a rental for 2 months!! And they have no idea when the part is going to come in! So I am now wondering what I should do

This reminds me of an event I witnessed several decades ago...

Was selling tickets at our local HS football stadium when a car alarm went off. Notified security who found it and said that nothing had happened to the vehicle. Announced for the driver to go to the vehicle to turn off the alarm, which they did.

Several moments later, the same vehicle alarm went off. Again, called for the owner who turned it off. This happened 2 more times that night.

Finally came to realize, through trial and error & security standing next to the vehicle, that whenever the HS band played a song, the clanging cymbals set the alarm off. The driver was told to park further away from the bleachers, or get a better battery.

Hopefully Honda is covering your rental cost. My 2020 has over 30,000 km with no issues so hopefully only a glitch for you. The pandemic has really mucked up the supply chain and certain parts (and new vehicles) are not quickly available.
If you are having multiple issues on the car you may want to consider buying an extended warranty before the 3 year warranty expires. It is damn expensive in Canada vs the US and I would only recommend it to someone experiencing multiple problems.

Yeah they are covering the rental cost thankfully, but it’s a car and no trailer hitch which I need to tow my boat. Yeah I have herd of the issues getting parts which is super frustrating

A weak battery can cause the alarm to go off from external forces?

And I'm basically having this same issue. I am taking it into Honda tomorrow for a diagnostic. I really hope they are able to find a fix for it quickly.

Took it to the dealer and they said they got the following code: U0418-6B, and apparently the body control module needs to be replaced according to Honda. However, they have no BCMs available and don't know when they will get them. I'm basically screwed and this car is useless now.

That stinks. How long is your lease?

I have 2 months left on the lease. This BCM replacement is going to cost $1,000 and normally it would be covered by the warranty but I'm 37 months in (I got a 39 month lease). This is super unlucky, I really don't know what options I have. I don't know if I can even trade this in right now for something new.

 

[JB in AZ]

... I don't know if I can even trade this in right now for something new.

As I understand it, the car runs fine, and the battery runs down "often". Is it every day? Not sure I saw how long it takes to run down. I remember someone else needed a BCM that was out of stock, and I think they disconnected the battery every night until the BCM was available.

You won't know if you can trade it unless you try. I would certainly try to avoid paying $1,000 for a BCM (that isn't even available) is your lease ends in 2 months. Maybe disconnecting the battery is a hassle, but worth saving the $1,000 until turn in time, especially if the part is not available?
