2023 Honda Accord Hybrid

Today I was driving my 2023 Honda Accord Touring hybrid with 8k miles on it. Out of the blue, a bunch of warning messages / lights came on ("Brake System Problem. Brake performance may be reduced. See your dealer."; also tire warning symbol). Car automatically decelerated (wouldn't accelerate). This would have been very dangerous happening on a freeway.

The car stalled suddenly with hand brake pulled automatically while driving at a slow speed at a parking lot. The information center shows brake indicator flashing in red with description statements that include the brake might have reduced power and how to restart the car. Was able to start the car after releasing the hand brake and drive without issue. Sent the car to dealer’s service department but they couldn’t recreate the symptom and was told there is no recall for this issue.

Driving at low speeds in Somerville MA on [XXX]. 1 yr old car with about $6k miles. It was a hot day. Front display lit up with warning about brakes being degraded and take to dealer. It also showed tire warnings, and traction control warnings. I believe acceleration was greatly reduced. Pulled over. Turned car off and on, and most of the errors cleared, except a brake warning. I drove 5 minutes home. Power cycled again, and the brake warning disappeared. I put a code reader on it, and it showed numerous communications issues. Problem did not repeat. I took to dealer. They confirmed the codes, and communicated with Honda corporate. Honda confirmed they were aware of the problem, but they do not have a solution yet. Google Search showed that it is an isolated problem. If it had happened at highway speeds, it could have resulted in a major accident Attaching code report to show communications errors INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2023 Honda Acord. The contact stated that while driving on two occasions at 45 MPH, six unknown warning lights plus the brake system warning light illuminated. The vehicle began to lose motive power and stalled. The vehicle was restarted. The vehicle was taken to a dealer where the failure could not be duplicated. The manufacturer was notified of the failure. The failure mileage was 9,670.

My 2023 car has 850 miles on it I was at a stop waiting for a train to pass when all warning dashboard lights came on. The brake would not work and the gas would not work. I turned the car off and restarted it and most lights went off except for the brake warning. I was able to turn around and take car to dealership. They said it was a faulty 12 volt battery and replaced it. I haven't had issues since but also haven't driven much. I have read of other honda owners having the similar issue.

Power Steering Failure. It is available for inspection upon request. After taking a right turn, the steering got stuck and did not come back as expected. This caused car crashing into the curb on the road, severely damaging front right front rim and tire. The steering alignments after the crash has been impacted - steering has to be tilted to make the car go straight. There are multiple warnings signs that include Brake System Warning, Vehicle Stability Assist System Problem, Hill Start Assist Problem, Adaptive Cruise Control System Problem, Collision Mitigation Braking System Problem I have video of all the warnings that I see. The warnings disappeared for sometime and then came back. I am taking the car to a Honda dealership for inspection and repair tomorrow.

Summary: vehicle shutdown while my wife was driving 25 MPH, lost all engine propulsion and brakes failed. Thankfully, she was driving in community/residential street and could pull over safely, rolling to a stop in a side lot. If she were at higher speeds or on a freeway, my wife and others could have been seriously injured. Details: Alerts for the brakes system "Brakes system problem. Brake performance may be reduced. See your dealer" and one involving tire pressure (cannot recall the exact message) came on at 35 MPH. She then came to a stop at a stop sign normally about 30-60 seconds later, then proceeded to accelerate again, continuing on her short route. At 25 MPH, the instrument cluster, all screens/electronics went black/off, propulsion stopped and brakes failed. She was able to steer the vehicle to a side lot as it rolled to a stop. After 20 minutes of attempts to restart the car, it finally restarted as if nothing happened. Further more, in between attempts to restart the car, the infotainment screen would randomly turn on, despite not having turned on the car at that time. Subsequently drove to dealer for inspection and awaiting response. Vehicle has had no other problems, only 5500 miles, just under 1 year old.

[XXX] My wife was driving this hybrid vehicle when it suddenly lost power in middle of road about a city block from starting location. There were no reasons for any automatic hazard overrides to become active. Dashboard displays stayed on but there was no accelerator response, and, importantly, there was an immediate loss of power steering and power brakes. Vehicle was traveling uphill and the emergency brakes had to be applied to arrest backward motion after coming to a stop. Judging by rate of slowdown, regenerative braking may also have been active. Rapidly following this, several diagnostic/warning messages (re brakes, steering, etc) started flashing in succession and then the message "see your dealer." About 10 minutes after this incident, my wife made one attempt to restart the car after turning the car off and then on. The response was a repeat of the flashing messages. I arrived at the scene about 20 minutes after this and the car restarted in a normal fashion. So, unfortunately, this is an intermittent, difficult-to-firmly-diagnose problem. Nevertheless, in view of the severe safety issues associated with this failure, we had the car towed to a Honda dealer. They found several items in the car's diagnostic system and, in consultation with Honda engineers, performed a software update for the ICM (ignition control module?) which, we were told, would address this problem, since other similar complaints had apparently been registered. The HUGE SAFETY ISSUE that this failure represents (loss of power along with steering assistance and braking assistance plus possibly more rapid deceleration) cannot be overestimated. We will be risking our lives to believe that the software fix truly addresses this problem. To believe that a software update is a sure fix is to believe that Honda knows the exact reason for this failure, and if they do, it is absurd that a software recall has not been issued. Please follow up on this matter with Honda. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
