Car was sitting in garage while parked and not in gear.
This issue w/your car has now been documented which "should" help in Honda looking into this issue, coming up w/a fix, and protect you from any associated cost(s) that would occurre w/that fix if it is found after your original warranty ends. I would think the more cars w/this issue that take their car back to the dealers when this warning is showing should provide them w/information & knowledge to what is going on resulting in a fix.I've had the CMBS error come up on my car 5 times since purchase in August of 2018. The first time it happened the car had about 800 miles on it. I called and went to the dealership each time. They told me that unless the error warning was still on they couldn't do anything. The last time it happened I was about half way home so I turned around and went back to the dealership with the warning still active. After 2 hours the still had no solution. Hopefully Honda comes up with a fix soon.
Every time I took my 2018 touring in for this problem, they stated different problems other than ACC. How can they keep a valid database?Honda only does that when you actually bring the car in and it’s documented. And as much as you think they probably don’t, they document and record every single failure. How do you think they put out recalls based off specific ranges of vins. But from a customer standpoint I understand the frustration. Trust me I dislike having to do warranty work on things that should of been caught in quality control.
How does an owner get a copy of these reports?View attachment 4309 View attachment 4310 If your CMBS ever has a activation it stores it in the control unit. Same for the lane departure. So the dealer should of been able to see all instances of it going off even if it wasn’t setting a code. As far as clipping a wire or unplugging something to deactivate it, no. You can turn everything off so that they aren’t active but anything unplugged will set DTC. Especially with the radar unit. If you trigger a misalignment code the only way to reset that is to perform a radar aim which sucks ass.
You can go to your dealer and ask them to print all your service records, having the same issue with my 2019 Accord 2.0 10spd, replaced brake switch, VSA module, and problem still persists and now my dealer is expressing that the car is operating as designed... I’m really hoping to get this fixed, and if I can’t be fixed, get out of this car.How does an owner get a copy of these reports?
I am currently having this problem, however mine was precipitated by a piece of a tire that a driver in front of me ran over, and it hit the front of my car. About 2 seconds after that happened the cruise control stopped working, the cmbs, my horn, and charging system went out. I don't know what is wrong with it. Going to have it looked at today.I have a 2018 Honda Accord 2.0T Touring. I have numerous incidents where the Collision Mitigation Braking System has gone out giving an amber dash warning to see the dealer. When this happens, the cruise control will also not function. Most times, upon shutting off the car and restarting, everything returns to normal. However, one time upon restart all other safety systems (even the turn signals and head-up display) went out. Only the Nav would work. Upon the next restart, all was back to normal. The dealer spent 6 hours in diagnosis and came up with a solution of adjusting a brake switch under the dash near the brake pedal. It did not solve the problem as it has recurred so now they are ordering a new brake switch. Has anyone experienced similar problems? I love the car but cannot continue to use it on highway trips if these safety systems are not reliable. That is the main reason I bought a new car.

I got the updated software last week and problem persisted and threw error on my 14 mile drive home the day I picked it up from the dealer.There is a correction for cars that code for ACC turning off while being used. It's a PGM-FI software update.
really? How close are you to cincy?I got the updated software last week and problem persisted and threw error on my 14 mile drive home the day I picked it up from the dealer.
Long ways away , I’m down here in Floridareally? How close are you to cincy?
I had the problem deliver put in new switch and it did not solve the problem. Turned out MOISTURE IN THE LEFT REAR TAIL LIGHT! CK FOR MOISTURE LEFT TAILLIGHTSorry to hear about the issues that you're having. Let us know if the new brake switch remedies the problem. Those issues definitely sound like something related to a faulty sensor. They give you an ETA on when the repair can be completed?
Moisture left TAILLIGHT causes this.I used the lemon law on mine to no avail Honda won’t budge. The lawyer said it was a mechanical issue he could get it solved but since it was a electronics issue they mourn likely won’t do anything about it. I’m just stuck with the detective car, and Honda expects me to put up with it.
I do wonder if this was a Honda execs car what they would do. I’m sure they would not just accept having a defective car
I hope that moisture in my tail light would not cause my car to break unjustified.Moisture left TAILLIGHT causes this.
