That should be 3 repair attempts. Dealers are cautioned not to attempt to repair problems that can not be verified or duplicated, the intent isn’t because they don’t want to pay for repairs, the reason is that there are people that will set up problems in an effort to get out of a lease or car payments.
2019 Honda Accord Hybrid: intermittent "brake system" warning light and on-dash warnings
that’s great catch, @Nevada_545!
the second time, I did not want to go to the same dealer who did not find a thing at first occurrence, so I went to another one, where I was admitted since I had no history on their books…
I have 2 more Honda dealers around to make sure it stays this way if I get to the same problem again 
It was said “never trouble the trouble before the trouble troubles you”…
Here is my 3rd one:
Any shares and up-votes on the video would be greatly appreciated.
Dropped the car at the dealership.
Quite interesting exchange at front desk, where they asked what the problem is, and once they’ve heard it is “brakes error messages”, asked if I have it NOW, and when I said “no”, asked then how they can know if problem still exists (?!?!)
I came equipped with the video I took yesterday, including mileage and VIN, so they had no choice but to admit the car into the warranty service.
That’s the third “documented repair attempt” strike…
I will post here as I get more news.
so… they asked to leave the car in shop until next Thursday… not sure why, but whatever…
I made sure to extract a “comparable loaner” from Honda to keep them motivated.
they gave me “Accord Turbo Sport” of the same generation.
call me picky, but this car sucks big time to compare to the Accord Hybrid: I can count “1-mississippi-2-mississippi” from the point I kick the gas pedal to the point where turbo really wakes up, while in hybrid response is instantaneous.
first I thought it is 2.0, apparently my mistake, it’s 1.5, so 10 less horses, but I’m already missing my hybrid one, it’s way more refined
I’ve just picked my Accord up from the dealer, it is hilarious…
They replaced the “seat switch” (part 71692) causing code B1829, which is apparently pointing to “somewhere between the front axle and rear axle”, which per Honda explanation did not have a separate report, but rather a generic one… which thy decided to map to the brakes malfunction diagnostic message ???
I though French have really unorthodox engineering decisions, but I did not know about Japanese engineering at that time…
On positive side, they finally acknowledged the issue existence and attempted the first repair, after 2 work orders where they simply said “we see no issue, it’s in your head”.
Anyways, I have no idea if this is going to be a permanent fix or if this is just a “get away from our eyes until if fails next time” type of thing.
After this new incident, I sent another certified letter to Honda plus opened case in BBB and another one in the Farfax County / Virginia where vehicle was purchased. Maybe it will add some motivation if it fails again.
It will certainly be interesting to see if it resolves the problem. That is quite a stretch. I certainly hope for you it does as it would be better to get this over with but I suspect you may be back at the counter again in the future. So good on you to keep the pressure on in the event it does come back. Thanks for updating!
Virginia Lemon Law limits me to 18 months from the delivery date, but makes a provision that if problm was reported earlier, it extends the deadline.
By this language, I have all the time in the world now.
Do you have the “electronic parking brake”? Subaru is having issues with that.
How would that apply to the OP’s Honda?
And, just for the record, the electronic parking brake on my 9 1/2 year old Outback continues to operate flawlessly.
It does apply IF he has an electronic parking brake. How about for now we just let him answer the question OK?
I do have EP, it works flawlessly.
The problem reported by self-diagnostic system was about the main brake system, not EP.
EP presumably has its own bucket of error messages.
Here are ones I was getting:
I’ve got EP on my 14 Legacy and I haven’t had a problem with it either. But Subaru has had enough issues with it that they have extended the warranty on it for 15 years and unlimited mileage. I would not assume that EP has separate error messages, but like I said, I haven’t had an issue yet.
Got another question, has these occurrences happened during a cold snap?
Nop, always after the drive, as I’m heading for the “touch-down” on a parking lot, while still in motion.
I agree with @TwinTurbo, it is quite likely I will be back to their service counter soon, as problem was repeating itself and it looks like they simply tried to “so something” to silence my complaints for a while.
Moreover, my all complaints were insistent that it is a critical safety issue, making it subject to Virginia Lemon Law from the very first occurrence.
They denied it against all facts, and since now I have a video recording including the VIN of the car on the same video, they might have changed tactics and decided to make some repair, just to show “we tried”, specifically not anywhere close to the safety features of the car.
I’m not sure… merely speculating…
Since this type of intermittent problem is so often due to a contaminate in the system, I would think that they would at least flush the brake system. They should include a bleed of the ABS as well.
You are asking for too much
First two times, they did not care to open the hood it seems…
On the last (third) “repair” I indeed observed they messed with a driver chair as the saved positions were erased.
On the brake fluid, to my surprise, after 8 months and 7000 miles the fluid changed from “invisible/clear” to “visible/yellow-brown”.
It seems to be a little bit too soon to compare to my prior Subaru/Nissan/Mazda experience.
Still, I will not lift a finger to save Honda from replacing this car if it fails again.
To me it’s unbelievable that the display has zero details about what problem was detected. Two pages of text with no details. I get the average person won’t find it useful but put it on page 2 at the end. Ex: Diagnostic code: xyz123b: pressure feedback out of normal range
Something. Anything. Other than “problem”.
I get you don’t want to touch it now but I would be so curious to hook up an advanced scanner looking for brake codes…
Yes, I agree, it is total travesty to show message like that and than not keep the malfunction code inside the BCM for technies to diagnose, this is what techs told me on the first two occurrences.
On the third one, I was kept far away from getting any info beyond “official narrative”, as once they spoke to Honda tech line, they found I’ve already went 2 steps out of 3 on the dispute resolution check-list.
I’m into the software engineering myself, and it is always a tug-o-war between us and marketing on exposing any details to the end-users, what may be found “confusing”, we do not always win to expose even a bare “xyz123b”, spare concise explanation of what is wrong.
So, “Houston, we’ve got a problem” is all we likely will get from the newer cars.
By now I have vendor-specific “advanced scanners” for Nissan and Toyota, getting one for Honda is not yet on my Christmas shopping list, and I’m not even sure Honda will be in my garage by the next time Santa comes to town.

Knock on wood. It’s entirely possible the failed switch is the cause of that seemingly unrelated brake system error message. Depends on how the switch failed of course. But If you’ve ever had a computer keyboard switch fail in the “on” position you know what sort of weird symptoms that can cause. Such a switch failure confuses the heck out of the computer software & can make the computer unusable; and in certain failure modes it isn’t obvious at all why the computer is acting so weird.
In any event it seems you & the dealership are on the right track now: they acknowledge there’s a problem, they found a problematic switch, replaced it, and now everyone’s awaiting the results. Hopefully the problem is solved. If not, what you need from them is a promise to keep working the problem until you are satisfied with the result.
It’s curious why they appeared to at first ignore your complaint. I presume this b/c in many customer new-car complaints if they just ignore it the customer will discover the problem isn’t worth fussing over or that the customer will discover the reason for the problem themselves. Sort of like the physician’s “take two aspirin and call me in the morning”. A wait and see philosophy in other words.
