2023 Honda Accord Hybrid electrical problems

Filed Jun 30, 2025 · Acceleration, Electrical · TX

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

The 12" infotainment screen flickers and turns off. The screen is most unresponsive. The screen never works with the headlights on. The screen flashes at night causing safety issues. Backup camera doesn't work. Multiple complaints found on redit regarding the same issue. I took to the dealer and they said I needed a replacement screen and it would cost $1200+. This is a practically new car.

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.

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.

The yellow brake System Light illuminates on my dash. . I took my car to the Dealership immediately after the Brake System notification illuminated and the Dealer said they don't know how or why. I have a photo of the illuminated yellow light. My Electronic brake doesn't engage correctly when my car is parked I have video of the Electronic brake operating incorrectly. When i speak to the dealership they state that the Red Brake light did activate incorrectly. My car also slammed the brakes when there was nothing in front of me, causing the seatbelt to pull my neck violently. I was at risk of being rear ended. I've reported this to Honda America multiple times. The last incident caused so much anxiety and panic that I will not drive this car. I do not and will not continue to drive a car with brake issues. Please investigate. My car has been to the dealership nine times in one year and parked since 2/7/25.

While driving at speeds between 3-70 MPH, the vehicle will intermittently display multiple warning lamps along with having an immediate loss of motive power (go into LIMP mode). When this occurs, the car must be coasted over to the side of the road & restarted typically twice to clear all of the dash alerts. Having a car go into LIMP mode while driving on city streets, highways or interstates puts our family in danger as well as the safety of others on the road near us. This issue has reproduced itself over a dozen times for our family & the service department has not been able to reproduce/confirm when brought in for repair. The service team on the 1st service date found multiple codes for loss of communications. They cleared the codes, found no permanent codes, performed a hard reset on the system & sent the car home. The 2nd service call again showed multiple codes for loss of communications. They were not able to reproduce the issue & sent the car home. The 3rd service call displayed the same codes as before. They updated the ICM software & sent the car home. The 4th service call displayed the same codes. The service team attempted to reproduce the issue by driving the vehicle for ~250 miles unsuccessfully & wanted to send the car home. We disagreed & they mentioned we should open a case with Honda which we did. Several days later Honda & the service team replaced the integrated control unit. It will take much time & many miles before we can be certain the ICM replacement did or did not resolve the issue. The issue 1st occurred near 6,200 in mileage and roughly 4 months after purchase. The car now has over 27,000 miles. As far as warning lamps during an event, multiple pop up that are images/icons as well as text of issues you can scroll through. Battery lamp, vehicle stability assist reduced traction and handling, brake system problem brake performance may be reduced, electric power steering system problem steering assist reduced, etc.

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.

Recurring issue where car loses all power to the powertrain, brakes, etc. while driving. Electrical systems inside the car and lights still functions, but complete loss of system to accelerate or keep the car going. After incident, computerized dashboard scrolls through multiple errors and then repeats (I have video). When I turn the car to the off position and then restart, only a single error for the braking system shows on the dash/computer system. If I turn it off again, and then back on, all errors are gone and the car drives "normally." Dealership could not repeat the issue and said computer system did not show any errors, even when I showed them pictures of the errors. First occurrence was 3/6/2024 on freeway during rush hour traffic, ~55mph. Car had 8010 miles on it. Second occurrence was 1/15/2025 on side highway where speed limit was 55mph; I was traveling about 40mph. Third occurrence on 2/7/2025 was just starting from a red light at an intersection and just made it through the intersection when car failed. Taking to dealership again for diagnosis.
