Driving on the white horse pike in Berlin New Jersey at 1:39pm on January 21st and my BREAK light warning light came on. There was nothing in front of me, I was doing 40mph. The roads were dry, There were no cars near me, and no traffic. It happened again on the same day January 21st, on the White Horse Pike in Lindenwold New Jersey.

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.
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.
I was driving down US Route 42 on 10/4/25 at 1:10 AM and my car phantom break itself while I was doing 60 miles an hour on the highway.
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.
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.
When driving my car it will phantom break when there is nothing in front of it going down the highway 5060 miles an hour and it’s done at numerous times. I have not been in an accident yet, but it’s something that keeps occurring on my car.
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.

The car brake by itself with no obstacles in the way
When I was attempting to merge into the turning lane the car slowed down by itself and abruptly stopped in the middle of both lanes while a car was behind me.

Rear brakes wearing before front brakes
2020 Honda Accord Sport 19,000 miles, driving slowly in neighborhood, automatic brake system engaged and slammed the car to a stop without cause. No obstacles no other vehicle. I have an apt for dealership to inspect. I discovered this has been reported by other owners when I researched online The consumer stated that they are no comfortable driving the car since Honda cannot identify the issue with the vehicle.

I purchased a 2020 Honda Accord in 9/2020 brand new. Within one month I started having brake issues. It felts like shuttering. I took it back to Honda service department; they stated the rotors need to be shaved a little. This did take care of the problem for about 8 months to year. I then started having the exact same sensation when braking at low speeds and worse at high speeds. I took it back to Honda (living in a different state) they said tech forgot to look at the brakes (it was there for oil change and tire rotation too) schedule to bring back and apologized. I scheduled a new appointment about 2 weeks out. They have my car all day and state they could not duplicate the problem. Service advisor states they believe it's happening at high speed/brakes heat-up was it okay for Service Manager to drive home because he lives a distance away. I did not feel comfortable with that, so he said to just drop by when I'm out and it's happening that a mechanic would get in the car with me to see if he feels the problem. I work Monday-Friday 8-5, I can't just stop in I explained. I was out of town over the weekend on I-95 going around 74mph and cars in front of me start hitting their brakes to slow down for traffic ahead we were on a slight curve in the road, my car starts shaking uncontrollably and giving that shuttering feeling then the brakes lock up. Thank goodness the car behind me was able to move into the slow lane and not rearend me at a deadly speed. My neck is still hurting from the locking of the brakes at such a high speed. I called Honda yesterday and scheduled to bring it back in again for the 4th time. I explained I will not take this car back without something being done to these brakes. At this point I feel it's a death trap. Let's see what happens Wednesday.
Since purchased I’ve had to replace the rear break pads 3 times and the vehicle only had 79,000 miles. Front break pads have not been replaced. It seems to be going through break pads too quickly especially for the back breaks.
