Brake failure and VSA system codes

I am curious if anyone has had the issues described in this dealer message from Honda: https://static.nhtsa.gov/odi/tsbs/2020/MC-10177331-0001.pdf

My wife had an issue with the car today and upon scanning, I am getting all three codes described in the message:

C0023-12 (Brake Diag Circuit ON Failure)
U0416-68 (VSA System Malfunction)
C0040-62 (Brake Lamp Switch Failure [Stuck])

I will be scheduling a dealer visit ASAP, just curious if anyone else has gone through the same issue. Though I found this document, I do not see a posted TSB recall.

Sounds like this is for the issue they're investigating. No TSB because the investigation was only recently opened. There's a thread on here about it from not too long ago.

Agreed. I tried searching before posting this and didn't notice any threads.

this is what I was thinking of. I haven't had any issues with mine related to the brakes or autobraking under cruise so I didn't look into it too much.
I have a 2018 Honda Accord 2.0. My car will break automatically when I am traveling on 190 outside of DFW in areas that they had put temporary lane stipes when widening the highway and since completion ground those stripes away. The concrete is a different color and when i'm approaching these areas the car thinks that i am fixing to run off the road at a high speed. The car breaks very quickly. So, what I have learned is that I need to be totally aware of this condition and when approaching I steer the car across these removed strips at a slight angle (not leaving my lane). I guess the system senses my movement of the steering wheel and does not break.

"BRAKE" = to stop
"BREAK" = Damage
I wanted to provide an update for my situation. These errors were caused by a small crack in my drivers-side taillight. Since it has been replaced, the codes have not returned.

It was most likely condensation that was causing random small shorts that threw the computer(s) off.

Thanks for the update... not the first time I've read of issues when water/condensation gets into the taillights.
I just got done experiencing the same thing with my 2022 Honda accord hybrid. I was driving down the highway and all of a sudden it started throwing multiple codes. Traction system failure, braking system failure, lane mitigation failure, cruise control adaptation failure, power steering system failure, even some of my lights we’re not working in the car and the fasten seatbelt alerts stayed on. Discovered I had condensation in my driver side tail light. There was a crack from where someone had hit it. I took the tail light out and turn it upside down and a bunch of water poured out of it. Evidently it was shorting my system out. I went on Amazon and ordered a new lights for $95. Installed it this morning and it seems that everything is fixed. I will attach the Amazon link for those of you who need a replacement tail light and lens. The dealership tried to charge me $700. The lenses for the 2018–2021 WILL fit in the 2022 accords. When you go searching it will not tell you that. Clidr Tail Light for Honda Accord Sedan 2018-2021 Rear Outer Taillamp Assembly Replacement Driver Left Side https://a.co/d/0Mt23VY
