The hand/emergency brakes activated without me doing it while driving and had stayed on ever since. I had my mechanic look into it and he mentioned may be due to a defective sensor and advised to have the dealer look into it for recalls. I saw that the federal safety agency is actually reporting on a similar issue. The car still has good brakes (pads and rotor) however the issue continues as it will randomly activate the emergency brakes.

Collision mitigation message turned on, took it in to dealer and they said sensor was coming up as malfunction and not aligned so they aligned it. Although sensor was aligned emergency brake still brakes without an obstruction in front. It has happened on interstate highway at speed limit where speeds are at 75mph.
The contact owns a 2020 Honda Accord. The contact stated while driving at an undisclosed speed with no other vehicles nearby, the Forward Collision Warning system activated briefly, applying the Automatic Emergency Braking. The vehicle returned to normal functionality, but the failure became a regular occurrence. The brake alert warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to the federal safety agency Action Number: EA24002 (Forward Collision Avoidance Warning). The manufacturer was not notified of the failure. The failure mileage was 54,000.
Car emergency braking system activates with nothing in front of me this has happend to me 3 times today it slowed me down to a complete stop on the interstate and took a few seconds to disengage with cars swerving around me to avoid collision this is a major issue
What component or system failed or malfunctioned, and is it available for inspection upon request? The Automatic Emergency Braking system engaged without any vehicle or person in front of my car. I was driving at about 40 mph and the brakes slammed on and then after a few seconds released How was your safety or the safety of others put at risk? If a vehicle was directly behind me, they could have slammed into my car. No car was at the time this happened. Has the problem been reproduced or confirmed by a dealer or independent service center? No, I haven't taken it in yet. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The BRAKE light came on on the dashboard when it occurred.
At least once a month with lane keep assist on, and a vehicle in the lane to my right, an emergency braking maneuver happens automatically. I have to disconnect the system
Check engine, right mirror, door, alignment. My safety is not good, the car jerks and merging into another lane. Yes it has been inspected by insurance representative. It appeared when I was hit on 02/13/2024
There several blind spots in this car, had a car accident due to blind spot.
Hi, My Honda Accord Sport 2020 1.5T got 3 of 4 fuel injectors malfunctions and led to all warning lights turn on. I had to replace them (cost appro $1,900) at the Southpoint Honda dealership in Durham, North Carolina. They told me there is no recall for this model. Honda is bad. Many videos shown the same issue with mine on Youtube. Please help us. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Vehicle was being driven at 38 mph on a road with no other vehicles, bicyclists, pedestrians or other obstructions in sight when the "BRAKE" warning flashed on the dashboard and the brakes were immediately engaged, causing a hard stop. Had there been a vehicle following, it is likely that a rear end collision would have occurred.
The contact owns a 2020 Honda Accord. The contact stated that on several occasions while driving at various speeds, the Forward Collision Mitigation Braking System notification message displayed, and the brake pedal was depressed but the pedal remained on the floorboard. The contact stated that the vehicle decelerated from 65 MPH to 15 MPH before abruptly stopping. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 55,000.
As I was driving down the main road at 45 mph, no cars, animals or people anywhere around me, my 2020 Honda Accord Sport automatic braking system HARD BRAKED out of nowhere for no apparent reason! Thankfully there were no cars behind me or there would have been a crash!

This is the third Accord I've owned, and none of them have been issue-free, but this one (2020) is the worst. I bought this car in March of 2021 with only 6 miles on it. Within a week it started to throw occasional notifications, which I called the dealership and asked about. They assured me that it was just a hiccup and to bring it in for a factory reset. They performed this reset, and the car appeared to be fine after that. BUT - Less than two weeks later, it started showing the four LKAS/CMBS lights and dash prompts - brake system problem, road departure mitigation system, collision mitigation braking system, and adaptive cruise control system 'problems', each saying 'see your dealer'. Made an appointment to bring it back in, and on my way to the dealership - having the car for only one month at this point - I was rear-ended by a pick-up truck at the red light turning onto the dealership street (he admitted he wasn't paying attention). Long story short, the car was repaired, Honda factory specs were (supposedly) restored, set and verified, and my car was returned to me. It was fine until about another month later, when it started to show the alerts again - more frequently than before. Contacted the dealer again, asked for troubleshooting assistance again, and they said they were booked. I took this time to look for this issue on-line, and found many incidents of other Accord owners experiencing these same issues plus several others (of which I also had a few - namely, the fuel delivery system frequently acting like it is running out of gas) - most saying no matter how long the service shop had their car, the issue did not get fixed. NOT ONE. I could not afford to be without my car for an extended period of time, so I continued my research, seeing that none of the owners got resolution by the dealers, so I resolved to just 'live with the issues' as the actual car drove fine (except for the fuel issue). It happens every day.
I was driving on the freeway when the car started to break on its own and also indicting to brake as if there was something in front of me too close. But there was no car in front of me or beside me. The car breaking on its own was a major safety hazard since I was on freeway and driving about 65 mph. If a car would have been right behind me I would have been rear ended. I did take car to the dealership and let them know what had happened. And they told me I would have to take car in for a diagnostic appointment and the problem would have to happen while tech is driving car so they could look into it. This has happened to me a total of 3 times.
Automatic 45mph to zero breaking with no cars or objects in sight. Almost caused a rear end collision due to faulty and unnecessary automatic breaking.
Three times in one day the emergency braking system has gone on automatically for no apparent reason. We were not at risk but are concerned we will be put at risk. There was no warning. We have not taken it in but will do so asap
The lane departure has two separate problems with both happen frequently, these are not one-time problems. 1. The system seems to pull the vehicle in the wrong direction. For example, if you the car starts to deft to the left, and makes contact with the left lane line, it feels like the pressure exerted on the steering wheel, or the drivetrain itself, actually pulls the vehicle further left. This has the completely opposite effect of what is intended. This is not 100% of the time. Sometimes lane departure does nude the vehicle back towards the center of the lane as expected. 2. The vehicle cannot safely determine lane markings. It frequently mistakes tar lines on the road as a lane line and attempts to correct the vehicle's course. The vehicle also does not know how new lanes/ending lanes work. It will often see a new lane line, from a lane newly added to the road (like when a lane splits into two), as a lane departure and will direct the vehicle to one of the two lanes regardless of driver steering. Each time this happens I have to be aware and manually steer the car where I want to go, fighting against the lane departure system. The car is available for inspection and has not been inspected by Honda.
The contact owns a 2020 Honda Accord. The contact stated while driving 40 MPH, the vehicle inadvertently decelerated without warning. The contact stated that after several minutes the vehicle started to operate as needed. On another occasion, while driving 35 MPH, the brake assist activated independently causing the vehicle to brake suddenly. On another occasion, while attempting to start the vehicle, the vehicle failed to start-up after several attempts. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the dealer for diagnostic testing. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 62,000.
when I am driving, there is no car in front of my car. Brake warning flash and randomly slam on the brakes without the I touching the brake pedal.
This has happened more than one time.The first time it happened I was going down a 2 lane road no one in front or back of me and I was going 65 with my cruise set and the car slams on break and stays blink break on the dash. The second time it happened i was going down a 2 lane road at 45 no one around and it slams on breaks really hard and blinked break across the dash.
Driving on the interstate going about 60mph with no one in front of me or behind me and the car brakes by itself. This is the fourth time this vehicle has randomly brake
The contact owns a 2020 Honda Accord. The contact stated while driving 30 MPH and accelerating, the vehicle experienced phantom braking and abruptly stopped. There was no warning light illuminated. The contact stated that the failure was experienced several times within a two-month period. The contact was able to continue driving the vehicle. The vehicle was not taken to a dealer nor an independent mechanic to be diagnosed or repaired. Neither the manufacturer nor the dealer was notified of the failure. The approximate failure mileage was 14,000.
Today I was driving my Honda (Accord 2020) about 30 to 40 miles an hour and suddenly the car decided to brake for i guess a fraction of a second. It is hard to describe but literally felt that someone slam on the brakes. I also got the brake alarm and the sign on the dashboard "BRAKE" (orange sign). I was taken by surprise, even my wife asked me, what was I doing?. It was only a moment, but it was totally unexpected, lucky for me, there was no one in front or behind me.

The vehicle automatically turned on the forward collision mitigation system when there was nothing to avoid. Vehicle went from 55mph to 20mph in about 2 seconds. Fortunately there was no vehicle approaching from behind. I had no control over trying to override the braking system. Had vehicle checked at Honda dealership & was informed there was nothing they could do other than make a note of the issue.
CMS - collision mitigation system stops working completely. 2 warning lamps on dash. Cruise control completely inoperative. Vehicle was initially inspected by dealer on 11/19/21with DTC U0401-92 - Temporary stop of integrated driver support system (rejected control request), also found U0416-68 VSA system malfunction. This issue happens every 1-3 thousand miles. Also with the CMS/braking system, it will alert "brake" on dash and brake hard if encountering repetitive shadows from objects that are cast onto the road. My safety and others safety were compromised due to hard braking and cars behind me that then had to brake, nearly rear-ending my car.
Driving on a two lane highway suburban area - 40 miles per hour in a 40 mph speed limit. No cars in front of me for at lease 1/2 mile - totally blank and clear road. A pick up truck behind me. Very little traffic. Suddenly without warning and knowing my foot is on the accelerator, the car brakes to a complete stop with no foot on the brake pedal! Complete random braking for no reason. Luckily the vehicle behind me was far enough and not too close which allowed him to swerve and avoid colliding into me. He passed me and probably thought I was crazy. I called Honda and they told me to bring it in which I did. They performed many tests in all areas and advised they could not locate anything wrong. I know there is an ongoing investigation with Honda Accords and dangerous random breaking, thus the reason for this incident to be documented. The general manager of the dealership was in touch with me and advised he would be doing some research. I could easily have been killed if not for quick thinking of the vehicle behind me, and also luckily no car in front of me. What do you advise? This is extremely disconcerting to know it could happen again.
If I have the lane keeping assistance on and go through an intersection the car beeps BREAK!!
Several times my car has slammed the brakes on its own when I have not touched the brakes and also when there is no car in front of me for it to detect the need to brake. The most recent time on 4/8 on the freeway.
