Was operating the vehicle at about 30mph and the braking system started malfunctioning by giving me limited braking power and throwing a bunch of lights on the dash along with sudden loss of acceleration. Tried to press the pedal again and it didn’t respond I drifted to a stop in the middle a lane in the road. Had to shut vehicle off then restart to regain function. All conditions were clear outside. The dealer I bought it from has been very suspicious since the purchase. Bought as a “certified pre-owned” but have had nothing but problems in the couple weeks of owning. Such as the TPMS system continuously going off saying “low tire pressure” the dealer has seen it multiple times and still can’t figure out the problem. They said they’re gonna start “throwing random parts at it” Issues just continue to get worse with little to no cooperation with the dealership. Will be inspected in the morning once it’s towed in. No longer feel safe operating vehicle. Warning lamps came on after the malfunction. Then flickered on and off a few times then stayed on when I restarted the vehicle.

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.

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.

Electrical drain in system causing premature battery failure and electrical misfiring that causes the car to shut off and flashing a brake warning message to contact dealer and once this occurs car won’t start until Honda link and hands free pairing are reconnected. Issue is if the misfiring drains the battery, driver is not able to reconnect the cars apps and pair the Bluetooth, therefore, car is not will be immobile until battery is recharged.

I noticed a loud grinding noise and reduced braking power coming from my 2020 Honda Accord while driving at normal city speeds. A local mechanic inspected it and found that the rear brake caliper was sticking and causing premature wear. I contacted Honda service, but they refused to cover the cost or inspect it under goodwill, even though similar issues have been reported with other Honda models. This issue puts my safety at risk as braking is compromised and steering becomes harder. The problem was confirmed by a local certified mechanic and is available for inspection if needed.

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 ANC module malfunctions already at only 67000 miles and causes a humming noise which is very annoying when driving. The ebreak also malfunctions during cold weather conditions. I have had to restart the car due to the electronic parking break not working properly. In case of an emergency I might need it and it may malfunction.
