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.

I applied the brakes and pulled up to a light and as soon as my car came to a complete stop all of the lights just started going off. The light turned green and I couldn’t accelerate anymore and almost got rear ended. I tried turning the car off but it didn’t turn off. Instead, it just made a clicking sound and I was able to accelerate and pull into a parking lot and I was able to turn it off and I turned it back on and it the brake system light stayed on. I drove to work and when I got to work I turned it off and turned it back on and the car is fine.

While driving on the highway multiple vehicle dash lights began flashing, including brake system, tire pressure, check engine; and the vehicle suddenly and completely lost the ability to accelerate. The car was clearly still on and in drive, but pressing the gas pedal had no effect. After turning off the car and restarting after a few minutes, the brake system alert persists. Car was towed to dealer out of concern for safety. The attached picture is after the vehicle restarted.

I was driving on a highway when the engine light came on and the car immediately started slowing down even though I was pressing the gas pedal. It flashed there was a failure of the brake system, collision mitigation braking system, road departure mitigation system, hill start assist system, and adaptive cruise control system. The check battery light also came on. The car decelerated on its own with brakes engaged. I had to choice but to immediately pull over and luckily was able to steer to an off ramp and into a parking lot.

The brake system sensor light appears on the dashboard and cuts off supply to the gas pedal. Not able to accelerate while sensor turns on, which is very unsafe.

I was driving a busy 4 lane street when the brake warning light came on. Car slowed down and I managed to turn off onto a side street. When I pushed the throttle there was no reaction. The car would not move. I shut it off and restarted then it would go. The Brake System Warning light was on. Said: BRAKE SYSTEM Brake system problem. Brake performance may be reduced. See your dealer. I drove straight to dealer, and they checked the car and cleared the codes. Could not find anything wrong. I was lucky to be able to get off busy street without incident.

On June 9, 2024, while I was driving on the highway, my new Accord flashed a series of warning messages on the right side of the driver information interface (instrument panel). The messages that flashed and scrolled through repeatedly are listed below: Electric parking brake system problem. Parking brake not available. See your dealer. Blind spot information system problem. See your dealer. Hill start assist problem. Vehicle may roll upon brake release. See your dealer. Transmission system problem. Performance may be reduced. See your dealer. Emission system problem. Power may be reduced. See your dealer. Additionally, near the fuel gauge a red BRAKE light flashed and an amber BRAKE SYSTEM stayed illuminated. This is upsetting because I've had my new Honda Accord just over one month and have fewer than 1500 miles on it. UPDATE: I took my new Honda Accord Touring to my dealer and they examined it and told me a solenoid needed replacement. They ordered the part which took several day and replaced it. The solenoid replacement did not fix the problem and the service manager said my car needed a new transmission (eCVT). I was shocked such a new car would require such a radical repair. After waiting two weeks, my transmission was replaced. However, I'm not confident in my car. I read on NHTSA that 2023 Accord Hybrid had a recall for eCVT transmission replacement. My Accord Hybrid Touring is a 2024 manufactured in 3/2024.

We purchased a Honda accord ( VIN and details below) , and after few weeks ( within 380 miles of driving, the car stopped in the middle of the road with a whole bunch of DTC's lighting up. the DTC's were indicating brake system malfunction, Internal temperature high, LKAS Malfunction etc. Had to tow the car to dealership

While driving our 2024 Honda Accord Hybrid, the vehicle suddenly lost all power. Message on dash in big bold letters told me to BRAKE!!!!! even though there did not appear to be any reason to brake . When I tried to brake, I was not able to and the steering was difficult. I was able to pull over and finally stop. I was in a precarious spot and did not feel safe sitting in the car since I was just over the crest of a bridge endangering not only myself but potentially other drivers coming over the crest . Numerous messages on the dash related to steering and braking issues . Examples : Brake system problem Electric power steering problem Reduced traction and handling Brake hold system problem Electric parking brake system problem , parking brake not available

While driving down a paved road that has multiple bumps at due to cracking and buckling at 40 MPH, the car dashboard had multiple indicator lights turn on with audible warnings. One of the most visible was an alert that indicated there was a problem with the electronic breaking system. I came to a stop light, and brought the vehicle to a stop, all indicator lights remained on. When the light turned green, the car would not move and was disabled. I turned on my flashers as I was stuck in the middle of the road. I turned the car off and back on. The errors did not clear. I turned the car off again and it indicated I needed to put the car in Park. Once I did this and turned on the car, it rebooted and all errors were cleared. Dealership was able to find the following errors logged: U0100-00, u0100-f1, u0101-00, u0122-00, u0122-f1, u0129-00, u0131-00, u0131-f1, u0151-00, and u0416-68. Dealership said this was due to an "intermittent multi purpose camera failure". They said that if this issue occurs again, they would replace the camera. My concern is, this issue disabled my vehicle and didn't allow me to move the car after it had come to a stop. This can cause a serious safety issue if stopped in the middle of the road like what happened to me. If this is a wider or known-issue it should be dealt with rather than waiting for the failure to happen again.
