2023 HONDA ACCORD Electrical System Problems

Describe the Safety Issue: My 2023 Honda Accord (VIN: 1HGCY1F28PA010141) stalled in traffic due to electrical system failure. A certified Honda technician found undisclosed non-factory wiring, exposed wires, removed aftermarket alarm components, BCM communication failure, and multiple hard codes that cannot be cleared. The vehicle has serious electrical defects that affect engine communication and safety systems. These conditions create a risk of stalling, electrical fire, loss of power, and loss of control while driving. The defects were present at the time of purchase but were not disclosed. When did the issue begin? Stalled in traffic and warning lights appeared immediately after purchase. Is the problem reproducible? Yes. Hard codes and electrical malfunctions reappear after clearing. Has the vehicle been inspected? Yes. Inspected at Team Gillman Honda North. Technician documented unsafe wiring, BCM issues, and recommended teardown with an estimated repair cost of $2,686.86. Has the manufacturer been contacted? Yes, through Honda dealership service. They confirmed the defects are not normal wear and are related to altered wiring. Has the dealer been contacted? Yes. The selling dealer refused assistance and told me not to contact them further.

Started the car and the system was not booting up Properly. Had to restart the car a few times for the system to boot up properly. Took 3 min to start up after restarting the car. No error codes just major lag and delay. Car was updated to the most current update and no new updates were available at the moment. Bluetooth also has a hard time connecting to mobile devices. Engine makes weird sound when accelerating on the highway in eco mode. Sometimes feels like misfires when accelerating. When entering the car from outside the seat sometimes does not adjust back to the original position stays at the extended position it does when getting out of the car. Requires me to adjust my seat consistently.

The infotainment system, audio, and warnings about parking collisions and lane keep assist are glitchy. The audio skips and stutters making hands free impossible. It makes commuting dangerous. Honda Corp and the dealership are saying there is no recall and nothing they can do with no eta on a fix. They attempted a OTA and manual software update but could not complete it. They said it is a known issue.

Summary of Incident: For approximately two years, my vehicle has experienced random electrical issues. All dashboard warning lights will flash at random times. When I take the vehicle to the dealership (Bell Honda), the problem disappears before it can be diagnosed. On September 27, 2025, and again on September 28, 2025, the vehicle completely stopped and shut off while I was driving. It would not restart. The hazard lights were stuck on and could not be turned off. This left me stranded and in a dangerous situation. After approximately 2-3 minutes, the vehicle was able to restart, but numerous warning lights remained illuminated on the dashboard. I had the vehicle tested with a diagnostic tool at an AutoZone, but no apparent issues were found in the system. Additional Information: This is an ongoing and unresolved safety issue that Honda has failed to address. This electrical problem, which causes the vehicle to shut down unexpectedly, is a significant safety hazard. This issue is in addition to another ongoing problem with the remote start system, which Honda has refused to diagnose and fix. Consequences and Concerns: The unexpected shutdown of the vehicle while in operation is extremely dangerous and could lead to a serious accident. The inability to use hazard lights properly further increases the risk to myself and other drivers. The intermittent nature of the problem makes it difficult to diagnose, but the consistent occurrence poses a serious risk that requires immediate investigation by Honda and the NHTSA.

Mileage: 37,200

I will be driving down the road and my vehicle will pop up with the brake message and slam by brakes. It does it randomly. It has put my safety in risk multiple times. It has done this on the interstate and thankfully there was no one behind me. I was going 80mph and it dropped me to 30mph in less then 5 seconds. The issue has not been reproduced since it does it randomly. The vehicle has been taken to the dealership many many times. There were no warning symptoms or anything. It just does it very randomly. I had an investigation open with Honda and all they said to do was take it back to the dealership. This car is an issue to public safety. I could very well be in front of someone one day who is not paying attention and there could be a very bad issue. There has been so many times these issues have occurred.

Accord LX dash says vehicle requires a software update. Car was taken to dealer. Dealer says they hooked car to a computer and says there is no software update available. Dash continues to say vehicle requires software update.

I have had 2 separate experiences with starting my car and the lights on the dashboard come on. A message comes on with rolling alerts that states the automatic emergency braking, steering assist, lane keeping assist, braking assist, hill hold, adaptive cruise control are all turned off. Additionally regenerative braking was also turned off. I took it to two different Honda dealerships for maintenance. (May 8th, July 20). If you wait 30 mins the alert will disappear. My most recent incidence occurred on Sept 2, I was out grocery shopping and the alerts reappeared while in motion. I was very afraid bc I have never had it come on while in motion. From my second visit July 20th I took it to get looked at and they said that they could not re-create the issue. So both dealerships restored the factory settings. Now this is my third time dealing with this. I took it on July 20th to have them update the system bc it continues to alert when turned off that there is a system update. I had to take the care back twice bc the system update kept alerting. While reading other people's issues I see it is connected to getting the system updated. I have paid a lot of money for this car and it only had 39 miles on it. I see that someone else has had this problem in the past. I travel for work and this is certainly an inconvenience. I want to know how serious is this problem and has other people reported this. See NHTSA ID Number: 11533957 for reference. I will be putting my photos on this report to show how the dashboard lights up. In my first visit they thought it had something to do with the electricity or battery as they explained to me, but the problem keeps happening. For the cost of this vehicle someone needs to find out what the issue is and fast. I do not want to have to abandon this care for my safety.

The car will completely shut off while in drive and while driving. Not the auto shut off feature as that is off at the time the car shuts off. This has happened multiple times and isn't safe. There is no indication as to when it will happen, but it will randomly shut off after a short drive or long drive. Once I turn the car back on there is nothing that displays on the dashboard to indicate what happened or why or any issues the vehicle has. It's as if the car wasn't on and I'm turning it on for the first time. The car was leased in February and has been experiencing these issues since the beginning of the lease.

On 5.20.23, performed required remote system update for 2023 Honda Accord EX (gas) with 3,410 miles on it. HondaLInk app indicated update was requested while car dashboard indicated the update was installed and complete. Immediately thereafter, the Check Engine Light went off (not blinking) and received following message: "Emissions system problem. Power may be reduced. See your dealer.". Habitual problem for Honda. I was forced to trade in a 2019 Accord Hybrid due to emissions problems causing blinking Check Engine Light with car computer NOT retaining error codes - see prior complaint to NHTSA - tracking #11521930.
