While I was driving on the highway, the brakes of my car suddenly were violently activated and I had not touched the brakes. If there had been a car behind me, it would have been a major rear end collision. It was over quickly and I accelerated back to the normal speed. I talked to the Honda Service Mgr where I purchased the car and he said he was unaware of the problem although I see that that nearly 3 million Hondas have experienced this issue.

There has been multiple times that when I am driving on the highway doing 60 miles an hour, the dashboard will light up to BRAKE the car when there is nothing in front of the car, no other car no trash nothing. It has done this on slower roads where the speed limit is 40 mph and under but it will actually brake the car and I have had cars behind me when this happens. This keeps happening multiply times a week.

To Whom It May Concern, I am writing to formally report a serious safety issue involving the automatic emergency braking (AEB) system on my Honda Accord 2020. The system has been engaging randomly and without cause, abruptly applying the brakes when there is no obstacle or hazard present. On multiple occasions, this malfunction has occurred while driving at normal speeds, including on highways and in moderate traffic. These sudden, unprovoked braking events have created extremely dangerous situations, nearly causing rear-end collisions and putting both myself and other drivers at risk. Despite there being no obstruction in front of the vehicle, the system behaves as though an emergency stop is necessary. This issue not only undermines the purpose of the safety feature but also significantly increases the risk of an accident due to unexpected deceleration. I urge Honda to thoroughly investigate this issue, as it appears to be a potentially widespread and dangerous defect. I am requesting that the company: •Address and correct the fault in my vehicle’s AEB system at no cost •Provide a clear explanation of the root cause •Inform me of any recalls or technical service bulletins (TSBs) related to this problem

Vehicle will randomly slam on brakes to a dead stop, engaging my seatbelt when engine braking behind a vehicle. Usually happens on surface streets when the vehicle in front of me is turning into a driveway/tight right turn. My velocity is decreasing & I am not at risk of colliding with the vehicle every time. System does not seem to register engine braking with a manual transmission as “braking.” I’ve nearly been rear ended several times due to coming to a dead stop in traffic. I’ve asked Honda how to permanently disable the system, with the only advice to turn it off manually every single time I start the vehicle.

On September 2, 2025 at 1004-1005 EST, my car phantom braked, when there was nothing in front of me and this time instead of just flashing brake on the dashboard, it actually breaks itself and threw me into the steering wheel thank God my seatbelt caught me, but it really choked me up. This has happened quite a number of times before, but this is the first time that it breaked when I actually stepped on the brake pedal it break itself myself also. The component is the automatic breaking for the collision impact that keeps phantom breaking on me. It has never been looked at by a dealer or anyone otherwise. The lamp that came on was the BREAK lamp where the rpm are at.

Driving on a clear road on a clear day with no car in front of me, the brake warning flashed and then the car braked on its own. There was NO reason for the warning or for the car to brake on its own. Automatic breaking isn’t even a feature on this car.

Multiple times while driving the emergency braking has engaged briefly. At first I thought it was detecting something in the road or a vehicle to the side of my car. That is not the case. It will apply this brake no matter what is in front of or around me. I have not noticed it doing it on secondary roads but it does it on highways and the interstate. This has created an unsafe situation many times.
