I was sitting in my car, and the entire steering and brake system went offline and the car had a bunch of hazard lights on and said to tow to a dealership. I tested the steering, and didn’t feel the wheels turn with the steering wheel, and the brakes went to the floor. When I went to shut off my car, it did the emergency shut-off (press 2xs or hold for 3 seconds). I attempted to restart the car about 4 times that night, and then I let it sit and tried it again 2 more times before having it towed to the dealership. The dealership stated they received the car and everything was suddenly fine and there were no code history, and they could not tell me the issue. Prior to this, the only issue I had was the car braking when no one was in front of me, but no issues with the steering wheel. With the entire brake system and steering system out, it could have caused a serious accident if I was driving at the time, but I was parked.

At approximately [XXX]. Pacific, I was traveling southbound in the fastrak lane of the [XXX] departing from Pleasant Hill, California headed to Pleasanton, California. As I began to accelerate, the engine began to sputter. Immediately, the check engine light flashed on, then the dashboard reported a number of issues ranging from brake failure, TPMS failure, power assisted steering failure, vehicle stability assist failure and a number of other issues that I have never encountered since purchasing the vehicle. The sudden deceleration almost resulted in other cars impacting my car as this occurred during the morning commute. I was able to safely navigate off of the freeway. I was on speakerphone with Honda when this occurred. Had I not acted swiftly, a potential high speed rear end collision was likely to have occurred. I immediately took the car to Concord Honda. The team at Concord Honda performed a diagnosis and advised me that my head gasket was leaking water into the combustion chamber which resulted in the sudden loss of power. I was and continue to be dissatisfied with the handling of this issue by Honda as my car has never been handled by another mechanic. My car has a perfect or near perfect maintenance record and should not have a blown head gasket at 80k miles especially since my car is meticulously maintained and serviced by Concord Honda.

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.

While driving on the highway at approximately 65 mph, the car warning system beeped and displayed several error messages, including problems with the power steering, braking, and road mitigation systems. I was told to get my car to the dealer immediately. I also noticed that the car seemed to be losing acceleration power. As I was driving in traffic, my main concern was to get the car off the highway ASAP, so I was not able to note all the warnings. I did exit the highway, coasting off an exit ramp, having lost all or most power. After shutting off and restarting the car, all messages cleared except the warning of a potential brake failure, and I think the TPMS warning. I was now able to drive the car home with full power. The brakes, steering, and everything else seemed fine. After getting home, I shut off the car for about 30 minutes and when I restarted it, all errors had cleared. The car then drove fine and after the weekend, I took it to my dealer. They ran the error codes, and there were some codes, but nothing indicating a problem. They said it was fine to drive, but to let them know if I had additional problems.

I was driving on city roads when vehicle lost power going up a slight hill and I was forced to pull over to the side of the road. I received TDMS Failure first then multiple failures. Restarted and was able restart but received the following warnings: 1.Brake system failure, 2.Park brake failure, 3.Collision failure 4.Electric power steering failure, 5.TPMS failure, 6.Low speed braking failure, 7.road departure failure 8.Adaptive cruise control failure, 9.Hill start failure. Restarted again was able to drive the vehicle home but received the above warnings. Restarted again and received a brake system warning. After I got home, I restarted again and all the warnings cleared. This was a very serious error. If I was driving on the turnpike when power failed, my only recourse would be to try to pull over, if possible, stop the vehicle and restart. This would be a life-threatening situation. Checked tires front tires were 36# rear tires 33#. So, no tire issue to trigger the TDMS warning. The auto technician did some checks but did not see any codes. He also looked at the Honda forum for technicians and saw some of the same issues, but they didn’t provide a solution. I mentioned what I read in the Accord Forum about the Honda dealer this person went do couldn’t find codes but knew right away that it was the ICM ignition control module. The technician said someone drove it today and will drive it tomorrow. He will also call Honda Engineers in California for assistance. 6/11/2024 I was informed that the issue has been confirmed to be the ICM module, which is out of stock now. 6/27/24 I received a call from dealer service advisor that the rental was approved by Honda, but also the part was received and the car will be ready when I pick it up. Car was out of commission due to parts availability issues for 18 days.

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.

The warning lights dealing with the braking system malfunctions. All warning lights dealing with the Braking system come on the dash. The brakes failed to engage and the car began to roll backward on a hill had to use the emergency brakes to stop the car. This problem has happened twice since I had the car on 12/6/2023 at which time all warning lights came on dealing with the brake system and on 01/09/2024 both times the car was tested by the dealership and no codes were showing but I have a video of both incidents I provided. Both incidents were reported to the dealership on the same day of occurrence. 12/6/2023 and 01/09/2024. During this time the car was in EV mode and the acceleration would not respond as well. The only way to get the car back running normally was to turn the car off wait a few minutes and turn it back on. The photos attached will show speed and any other information needed because it is two different occasions of the same issue. In the second incident, a vehicle was behind me as the car began to roll back on a hill and I engaged the emergency brakes to avoid rolling back into the other vehicle.

The 2023 Honda Accord Sport Hybrid has 8302 miles and it had complete brake failure. We had just refueled the car and moving away from the pumps, the pedal sank to the floor. I pumped the brakes several times and was able to stop the car. This was at about 3MPH. Received a message on the dash that the brakes were compromised and not to drive the car. Shut the car off and restarted. The brake pedal was spongy. We drove home (about 2 miles) very slowly, using the brakes minimally. When I got home, I shut the car off. I decided I wanted a picture of the dash warning, but it didn't return. Went for a very low speed drive to try to duplicate the problem, but it seems normal now. Bringing to original dealer, 12-17-2023. We've had several other issues related to the parking brakes and cruise control on 11-13-23. Brought to dealer on 11-16-23 and they were unable to fix due to part shortage. They failures displayed are: 1 - BRAKE SYSTEM - parking brake not available. 2 - BRAKE SYSTEM - Brake hold system problem. 3 - adaptive cruise control system problem. The drivers side rear seatbelt will not retract. Brought to dealer waiting for part to repair. We are fortunate this happened in a parking lot with little traffic. If this happened on a roadway at speed I would have no way to slow the car. This is a Hybrid so I am not able to downshift, the parking brake is not functioning due to previous problem and the electronic drive doe not provide compression braking if I shut the car off. I would be happy to answer any further questions you may have.
