2023 Honda Accord Hybrid

Vehicle Power Loss and System Malfunctions I am writing to formally express my concern regarding a recurring and potentially dangerous issue with my vehicle, 2023 Honda Accord Hybrid. Twice while driving, the vehicle suddenly shut down on the freeway and completely lost power. In both cases, I was fortunately able to steer the car to the shoulder of the road, but this posed a serious safety risk. During these incidents, multiple system error messages appeared on the dashboard, including alerts related to braking, lane departure, and other critical functions. Alarmingly, this same issue has also occurred while the vehicle was parked in my garage. Each time, the only way to temporarily resolve the issue has been to shut off the vehicle and restart it. Upon restarting, the only remaining warning is related to the braking system, along with a prompt to bring the car to the dealership. If the vehicle is restarted again, all error messages disappear. I have contacted my dealership after each occurrence and brought the vehicle in for inspection. My car is currently at the dealership, and I am awaiting information on the cause of the problem and the proposed resolution. After the first time it happened, I have taken video/pictures of the errors and supplied same to the dealership. I consider this a serious safety concern—not only for myself but also for any passengers and other drivers on the road. Quite honestly, I am now afraid to drive the car, knowing that it could unexpectedly shut down at any moment without warning.

I was driving on the highway yesterday when all of a sudden several errors flashed on my dashboard, and my gas pedal stopped working. When I pulled over, I noticed an error code that read: "Brake System Problem. Brake performance may be reduced". Not only did I lose all acceleration control, but the error codes tell me there are brake issues. After researching online it seems like many others have experienced this issue and some people found the issue was caused by a faulty Ignition Control Module.

On 5/8/25 when the light turned green at the stop light, my car shut down while the gear was on drive. It immediately came back on with the dashboard showing warnings for the (TPMS), brakes system, stability system, among others. I accelerated while on drive but the car did not move forward. I turned the flashers on. I had cars behind me honking and going around me. I put the shifter in Park. A car behind almost rear ended me. I tried a second time to go by shifting the gear to Drive but I had no luck. I put it back in Park and turned it off. I turned it back on and the dashboard seemed fine, the car accelerated when I shifted it to Drive. This is the second time that the same car shut down on me, the first time was over a year ago when the car was in motion at around 40 mph, I was able to pull over. The first time the dealer replaced a part and told me the problem was fixed. This time around the advisor said there's nothing they can do because they can't replicate the problem. It's very concerning because it can happen at any time anywhere at any speed.

The contact owns a 2023 Honda Accord. The contact stated that while attempting to park the vehicle, the brake pedal was depressed; however, the vehicle independently accelerated. The contact veered to the left and struck a cement pole on the front driver side, where the vehicle came to a stop upon impact. The cement pole did not show signs of damage after the impact. The contact then parked the vehicle at the scene. No warning lights illuminated; however, the message “Initializing Driving” was displayed. The vehicle was then towed to the dealer; however, the dealer declined to repair the vehicle because the vehicle was out of warranty. The driver’s and passenger’s side air bags did not deploy. A Police report was not filed. There were no injuries sustained; however, the contact had a tight feeling in the right shoulder. The vehicle was not diagnosed or repaired. The Insurance company was contacted. The manufacturer was notified of the failure, and a claim was submitted. The failure mileage was 45,606.

I was driving approximately 60 mph on a local highway when my the check engine light came on. The dashboard then started flashing warning messages for multiple error messages stating that many features were failing such as power steering, acceleration, brakes, lane assist, stability assist, and more. My car then lost power and decelerated, coming to a complete stop in the middle of the highway. I was unable accelerate or steer my vehicle to the side of the road. No one hit me but this could have easily caused an accident where either myself or others were hurt. I turned the car off and when I restarted it, my dashboard message stated that I had a brake system problem and that I should see my dealer. I was able to drive to the dealer where they ran a diagnostic and could not replicate the problem. They only stated it was a loss of communication in the computer but that "it would probably not happen again." They did nothing to identify what could have caused the loss in communication and said if it happened again, to bring the car back. I plan to take it to a certified mechanic to inspect the vehicle but I feel very unsafe driving a car that may lose power.

See video here: [XXX] Description: Driving at a slow speed, all of a sudden my car went dead. Brakes went out, gas didn't work, and the car went through a series of errors essentially telling me nothing on the car worked. For around 30 seconds to a minute the car was non-responsive. Then eventually power came back and I got an error message telling me to take the car in because of a brake malfunction. This brake message was on the dash until I parked the car again, then there was no error and the car started up and behaved normally. This has happened twice, once in a parking lot, once in a parking garage. Luckily neither time I was headed towards another car, as I would have crashed.

The vehicle unexpectedly stalled - lost power while driving and the brake system warning light came on. There were no warning lights, messages or other issues with the vehicle prior to this failure. Was fortunate that the car coasted to a stop on the side of a busy road with no traffic following behind. The vehicle was then towed to a Honda dealership for inspection. Was advised by the service department that there was a software update - unbeknown to us. The error code was cleared and the service department completed the pcm update per Service Bulletin 25-017.

On three separate occasions (the most recent of which was on Saturday), my vehicle’s dashboard lit up with various alerts, including “Brake System problem”, “TPMS problems”, and “Vehicle stability assist system problems”. At the same time, the vehicle’s accelerator completely stopped working. The issue would only resolve itself (and the alerts would go away) after I pulled over and restarted the vehicle twice. This issue happened on Saturday (on a highway), in March 2024 (driving out of a parking lot), and in February 2024 (on the highway). This is a safety issue because not being able to use the accelerator on the highway could potentially have lead to a serious crash. The dealers have been unable to replicate the issue. I've brought in the vehicle to dealerships on three occasions and have been told that because the alert wasn't actively visible when I brought it in after the fact.

All of a sudden, the accelerator pedal stopped working --- all I really know is that the car wouldn't accelerate, regardless of how much I pressed on the pedal, and the car had to roll to a stop. A bunch of warning lights came on about the brakes malfunctioning, but I don't remember if the brakes actually stopped working (I was more focused on the fact that I couldn't accelerate --- this happened right as I was starting to move after a red light turned green). Thankfully this happened when I was going slowly in a residential area --- if I had been on the freeway and unable to get over to the shoulder before the car came to a halt, this could have caused a serious/fatal accident (or if the brakes really had stopped working, even in a residential area I could have crashed into something/someone). The car remained unresponsive until I turned the whole thing off and on again, at which point it started working like normal (although still with the warnings). I took the car to my dealership and they ran diagnostics, but they couldn't find anything and couldn't reproduce the problem when they drove it around, so they just shrugged and said I should "keep an eye on it and see if it happens again". So unfortunately I don't know what caused the problem or what to inspect (but I'm certainly not going to keep driving the car and risk this happening again).

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.
