2023 Honda Accord Hybrid: sudden loss of power

Filed Mar 1, 2026 · Brakes · MO

During transit, the dash displayed several errors and then finally stated that there was a "Brake System problem, Brake performance my be reduced. See your dealer." The car lost power and I had to find a parking lot to exit the street to. After turning the car off and back on the car drove normal but with the Break System error still on the dash console. After parking the car for a while at home, I restarted the car and the error was no longer displayed and everything seemed normal again.

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.

Lost all power and the warning light came on concerning brake system failure. The car came to a complete stop and would not accellerate, so had to shut down the system and restart in the middle of the road and luckily was able to drive home with only a brake light illuminated. There is definitely something wrong with the electrical braking system

12/22/23: I was accelerating onto the highway when multiple error messages popped up on the screen related to brakes, emission system, power steering, and others. The car’s accelerator lost power and slowed to a stop on the side of the highway. The interior electronics didn’t lose power, and neither did power steering or power brakes to my knowledge. I restarted the car and the warning lights remained on, however the accelerator appeared to function normally. Honda was unable to diagnose or fix. 3/31/25: I was pulling out of a parking deck when the engine lost power (no throttle) at the same time that multiple error messages came on to the screen. I coasted into a parking spot (brakes appeared to work) and turned the car off. I turned it back on and all of the lights had turned off except a warning about the brakes and TPMS (I think). The engine appeared to work normally, and I immediately drove to the Southpoint Honda service center. 4/8/25: Recap from Honda: Your car had a couple issues, they're all related. The first thing you're complaining about the stalling condition that is a known issue. There's a software update that fixes that. So I got it in here to do the software update, but then I could not communicate to the vehicle. The can Gateway module was unresponsive, which the car will run fine without it. But then, I can't talk to the car. So after testing everything and finding the module to have failed, I replaced the can Gateway this morning. Everything's communicating fine and software is updating right now for the module. Then I'm going to update the pgmfi software for the ICM system to correct the communication loss within the network that causes the stalling issue. So those two issues will be corrected.

Vehicle Identification Number (VIN): [XXX] Vehicle Mileage: 29,200 miles Involved Honda Dealership: McGrath Honda, St. Charles, IL Details of Your Inquiry: I am seeking assistance regarding an ongoing issue with my 2023 Honda Accord Sport Hybrid. The first time I noticed this issue was in the summer of 2024, when I experienced a similar set of alerts while driving in a parking lot. At the time, I didn't think much of it, as the vehicle seemed to return to normal shortly afterward. However, on [XXX], the problem occurred again, but this time it was more serious. While driving in a subdivision in Bolingbrook, IL, at approximately 25-30 MPH around 8:10 PM, my vehicle malfunctioned and displayed numerous system alerts, including: Adaptive cruise control system problem, Collision mitigation braking system problem, Road departure mitigation system problem, Electric power steering system problem, Electric parking brake system problem, Tire pressure monitor system problem, Brake system problem, Brake hold system problem. Additionally, my Honda app sent a warning stating, “Brake system problem, drive with caution.” During this time, the vehicle experienced a significant loss of power, with no braking or acceleration available. I was unable to use the brake pedal or accelerate, which caused immediate safety concerns. Luckily, I was in a subdivision and not on a busier road like Weber Rd. or I-55, as this could have resulted in a dangerous accident. I was able to coast the vehicle to a stop at the side of the road, where I waited for a few minutes. I then cycled the vehicle off, waited a few more minutes, and turned it back on. The vehicle started, and I was able to drive back home. A video was recorded showing the alerts on the dashboard. I brought my vehicle to McGrath Honda for diagnostics on March 28, 2025. The dealership found multiple lost communication codes from various subsystems, but they were unable to replicate the issue.

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.

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.

This happened on [XXX] at roughly [XXX] pm. I bought the new 2023 hybrid accord ex-l in June 2023 and the car only had 12413 miles. I was driving in Slidell, LA along [XXX] road towards [XXX]. I was driving 45 mph with adaptive cruise control. Suddenly there were lots of warning lights on. I don't really remember clearly how many warning lights since I was shocked. But I think that the "check engine", "tire pressure", "road departure", "traction", and "brake" were on. It was like fire work and at the same time, the car was losing power and the power steering was becoming stiff. Luckily there were no cars behind me and I was right by the entrance of a subdivision. I was able to turn into the entrance of the subdivision and the car basically stopped by the stop sign, kind of like dead. I was blocking the road and had to restart to car. But luckily I was able to restart and then there was only one warning messages left, the brake (please see photo). It says " Brake system problem, Brake performance may be reduced. See your dealer". It was after 7 pm and I didn't think the repair department was open. So I took a photo and slowly drove to Abita Spring. After parked my car for maybe two hours and I then restarted the car, everything seems ok. No warning lights at all. So I drove back home. Was busy on [XXX] and [XXX] (Wednesday and Thursday), finally went to the dealer on Friday, [XXX]. There was no codes and the dealer cannot do anything even after showing the photo. Was told to pull over to the dealer and they need the code. It's been two weeks and the car seems fine. But if someone drives on highway, ~70 mph, this can be fatal. And HONDA needs to address this!
