2024 Honda Accord electrical system problems

“1. The service center diagnosed the BCM as faulty. I do not have the faulty part available as it was replaced. Service center work notes: Vehicle no start confirmed, battery voltage is at 12.4V. Vehicle has message on dash to touch key to ignition start stop button, with no success. Proceeded to inspect all main fuses to under hood fuse box, found all fuses are good main 175 amp fuse is ok, along with all four multi fuses. Proceeded to follow troubleshooting for message displayed on dash, tested key fob for unlock and lock functions, tested start stop button functions with no issues. Checked fuses that power is at each supply pin, pin 1 on connector a has 12.2v and pin 18 12.3v. Used the ground from connector pin 51 while testing voltage on previous pins to confirm ground is good. It is suspected that bcm has a internal failure and will need to be checked with known good unit, reprogrammed and retest to confirm vehicle will start. 2. The car in the faulty condition had no noticeable difference from one with a low battery so I tried to jump start the vehicle per the owners manual. This put me at a significant fire risk of over charging the battery. 3. Unknown if…”

“Attempted to turn car on and it did not turn on. It asked me to place my key fob on my “push to start” button. After doing this nothing happened. I went and grabbed my spare key fob and still it did nothing. Eventually got it towed in and dealer confirmed it was a bad body control module. There was no warning light or message prior to this”

“The vehicle is experiencing an immediate and severe safety hazard due to a total electrical and mechanical failure within the steering column assembly. The driver horn has stopped working entirely, leaving the vehicle with no way to audibly warn pedestrians or other drivers in an emergency. Additionally, all integrated steering wheel auxiliary controls and buttons are completely non-functional, which points to a failed clock spring/cable reel or an electrical short inside the steering column. This total system failure creates an unacceptably high risk of a collision and raises severe concerns regarding whether the driver's steering wheel airbag will properly deploy in an accident. The vehicle is currently un-driveable, legally unsafe to operate under state transit laws, and induces extreme driver anxiety. The vehicle has a pre-existing history of abnormal steering wheel noise and dashboard volume knob defects that were previously reported and serviced at an authorized Honda dealership during the factory warranty period. The defect has now returned in a catastrophic state. The vehicle is currently held at Twin City Honda (Port Arthur, TX) alongside four…”

“Apparently a very well known issue, I've had my car for 17 months and the software error see dealer had been on every time I start my car for the past 14 of them. And sometimes when I'm driving. Took it to the dealer, as the screen prompts, they said they reset it, turned it on, and there it was. Don't think they even did anything, except maybe waste my hour and a half and then try to sell me services. I know there is a known issue with the software on this model shutting down the vehicle whilst driving, I sure hope that isn't the case with mine. I'll try to take it back to the dealership, but like I said, they either didn't know, couldn't fix it, or just wanted me to get new brakes the first time I was there, and I'd really rather make sure that it gets done correctly if I bring it back. Thank you very much, and have a great rest of your day”
