The easiest thing to point to is the Valet Mode showing up, if you have it. Easily verifiable and listed in the TSB. Otherwise, I’ve found complaining of the sensors applying braking too aggressively helps bc it’s difficult to prove that’s not the case and it’s a safety concern so easier to justify a fix.

Yeah, being a November build, I don't have valet mode, I see the BRAKE graphic already, my memory seat works properly, etc. So those were fixed on the line. I haven't had the screen black out yet. I want the "improves" categories, especially since someone noted the AC is improved. I think it's meh. Functional, not cold. Like what exactly is "Improves UI by adding virtual controls"? It's as non-descript as some of the updates I get in my Mach-E.

I think this may refer to adding the dome light option in the top banner controls. Nothing crazy.

I am a may 2024 build, and I dont have valet mode though. is that odd?

Odd? No, not really. We don't know when it was removed in the production line. When the forward collision warning goes off, is it just audible, or is there a red BRAKE in a box that appears on the windshield HUD (even if you have HUD off)? That was added with this update, but I've always had it...

it says brake, I dont have elite, so no HUD.

Possibly we were wrong as far as when they fixed it. I had seen a May production which still had the original defects. I had seen a July which didn’t. Someone report that they had a June which didn’t. Likely you still need the update as @Mrbig has an August build and he is getting the update

This is the problem with Honda. They won’t do software updates unless it fixes a customer complaint or is a recall.
They don’t have the mentality that other EV brands do that these fixes generally improve the car.
I’m anticipating having to fight with my dealer about it.
If anyone knows of a Honda dealer in SoCal that won’t be awful about this, please let me know.

Not true. I have no issues and they are installing the bulletin update

Those are posts within the past two days. My service manager told me the exact same thing, since my car doesn't have the issues listed as it's a late 2024 build. It's a mentality that they don't understand proactive software updates. I didn't force it yet as I wanted to see some others install it first and see if there were problems. I'll take it up when I need to inspect my car.

A late 2024 build may not profit much if at all from the update. My car was an early build (April 2024). There are a great deal of improvements in the update for me.

Agreed, however some Honda dealers aren't taking the right stance. From the TSB, there are a bunch of "known issues" and some things are listed as "improves", which isn't necessarily fixing something that is obviously broken. The size of the update (10GB) forcing it to not be available via OTA tells me there's more in there than they are listing. Every 2024 VIN is listed, so they will all benefit in some way. I've never had the blackout screen yet, but I have no way to know the conditions it may occur. But this software supposedly reduces the chances, so I want it.

It should not be for the dealer to decide...my car is eligible. Just like the battery update they pushed out in the spring. It's for all 2024 VINs, and says "intermittent loss of heating or cooling in the cabin and may display a Service High Voltage message or DTC BTBAA." I never had the problem, but got the update to reduce or eliminate it from happening in the future from these conditions. I appreciate that, since obviously breaking down isn't something anyone want to experience. Dealers are lazy, and in this case don't want to deal with the GM side of the house.

A month ago, I contacted my dealer, told them about the bulletin, sent a copy to them and they scheduled an appointment, no questions asked. My Prologue is a September 2024 build. So, it seems some dealerships are lazy and don't want to do anything they don't have to, even though Honda is paying them. My dealership is different. They are red carpet all the way. If I decide to stay, I get fed, have drinks, watch movies, test drive cars and if I decide to leave, they call me an Uber at their expense. If they keep the car more than one day, I automatically get a loaner. I can go there anytime I want to charge the car as well. I suggest finding another dealership close to you and giving them a try.
The first time I went, they told me that they had not even heard of it from Honda, and I was the first one. So, I'm the dealership's alpha tester. They tried the first time and failed to successfully download the files. After the second appointment, they found they had the wrong version of the USB drive. So, they ordered the proper drives. I'm now scheduled for my 3rd appointment. The other situation is the files come from 2 different servers and they have to connect to Honda, who connects to another Honda and GM server. And they have to have the car connected, as well, or the update will fail before it even gets to the car. I brought my own USB drive, but they wouldn't use it because of the liability. I told them I'm a tech by trade and could probably get it done. But again, because of liability, the answer was no. So, hopefully the 3rd time will work.

I agree with @Mrbig. It is the quality of the dealership versus Honda itself. I would recommend @cheerioboy26 that you do the same thing that he did, print out the TSB and take it to the Service Manager bypassing the Service Advisors. If that doesn’t seem to work, assuming you bought the car there, take it to the General Manager and inform him that if they don’t do it, you will find another dealership that will and you have bought your last car from them. In my case, I have known the Service Manager since he was a brand new Service Advisor since I have been going to that dealership for 33 years. He agreed that the update was available, and I a scheduled the update for the next day. I told the scheduler that is was a recall to get be on the schedule and told the Service Advisor that it was a Software update under warranty and he could talk to the Service Manager if he had questions.

Now if you look at the TSB, Honda is only going to pay them .9 hours to do it (unless I missed something) and it does tie up a technician a lot longer than .9 hours between the download and the upload in addition to securing a Stick to put it on and transfer. Technically that may be all of the time it takes and the technician theoretically can be doing other things while waiting download and upload except for the fact that there are likely to be glitches downloading.

I was alpha at my dealership and they did it in a day on one visit

Yes, you have a good dealer and I wasn't trying to imply they all suck. Mine is actually pretty good....when I bought my Odyssey many years ago right off the truck (it was still in transit) it was at the same time my twin daughters were born. They drove the vehicle to my house (40 min) on the day they were released from the hospital, and brought balloons. Nice touch.

Anyway, this could have been much easier if Honda sent out multiple OTAs (like GM is doing so it's possible) instead of one giant package that requires a dealer visit. I know in the early Ultium days GM did have some dealer only updates, but they let their customers know in car.

This is not my problem, although I agree it will take longer.

I'm aware of my dealer choices, I may contact the dealer 10 minutes from me (closer than the purchasing dealer) and see what they say. I'm not in a rush. As I said on a later reply, Honda corporate could have done better too.

 

[RonRecalcitro]

Honda corporate should be telling its dealers to do this update. This laissez faire attitude is bs.

 

[jonarogers]

I also concur that there are things. It expressly listed in the TSB that are fixed in the update. My car now properly displays all theee digits of the temperature goes above 100 degrees. That is not listed in the TSB.
So what if there is something more serious that is not listed in the TSB but is also fixed? Maybe a thermal or charging issue? If the dealer insists that they need to see on the TSB as an issues that they need to verify? The car won’t get updated because it isn’t listed. That is an issue.

Took my 2024 Prologue (born 24Apr2024) in for the software update. When I scheduled the appointment, here is what I included:

"Customer Note: Forward and Rear emergency break sensors, Driver Seat Memory Position. My research found a Honda Service Bulletin 25-051 from June 26, 2025 indicating a two step software update, which requires a Job Aid first, to fix these problems. "INSPECTION AND REPAIR PROCEDURE 1. Follow the steps outlined in the Job Aid: Honda Updating Control Units Modules with TECHLINE CONNECT under section INSPECTION AND REPROGRAMMING PROCEDURES (A11 RADIO) to determine if an update is needed for the A11 Radio Control Module. 2. If an update is needed, follow the steps to update A11 Radio Control Module including USB, Programing 1 and Programing 2."

I even offered them my 256GB thumb drive which they said would not be necessary. They planned 2 hours for this. They gave me a loaner, just in case.

30 hours later, I picked up my Prologue. They did ultimately need to go out and purchase a 256GB thumb drive. It's only been 5 days, so far no phantom breaking. The seat memory functions properly. But most importantly, my dealership service department has been very responsive to my concerns. After replacing the hybrid battery and the charging control module, two previous and separate events a few months ago, the software update may seem trivial in comparison. Nonetheless, Open Road Honda in Edison, NJ has provided service with a smile and genuine concern for customer satisfaction.
