While driving my 2020 Honda Accord Hybrid, VIN [XXX] , the car would start exhibiting rough engine feels, and all of the dashboard lights would come on. The car would lose power at highway speeds, and I’d have to pull over to turn the car off and on. When checking on OBDII meter, getting P0301 codes. I have replaced the coils and plugs twice and still not better. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
On December 4 at 8:57pm I was driving on interstate 295 doing 60 miles an hour and my car’s warning light for breaking came up for me to break like something was in front of me even though there wasn’t, this is a continuing thing going on. I reported every time it happens.

Honda never contacted me about this recall or steps to fixing the problem to make sure my car was safe and running/working correctly. I would like the problem/recall to be fixed ASAP. I looked up my VIN on your website and this is how I even found out about this recall. Please help me get it fixed. Thank you.
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.

The vehicle keeps braking automatically with nothing in front of me, I see numerous people reporting it so I figured I should aswell, nothing in front or near me when it automatically brakes, it is scary as heck tho!

Good Morning, I have new Honda Accord 2020 which always been taken care of regular services and oil changes etc. This morning I tried to start my car going to work but suddenly all brake related warning signs came off.

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.
On July 30, 2025, my Honda’s Collision Mitigation Braking System (CMBS) randomly activated without any obstacles in front of the vehicle. Since then, this issue has happened numerous times while driving. When the incident occurs, the system flashes a “Brake” warning and suddenly applies the brakes while I am driving. This creates a serious risk of a rear-end collision, loss of control, or bodily harm. I had the vehicle inspected by an authorized Honda dealership on August 1, 2025 for this issue. Despite the inspection, the malfunction continues to occur. Although I have not yet been involved in an accident, this defect poses an ongoing safety hazard for myself, passengers, and others on the road. I request that NHTSA investigate this matter.
The Honda Collision Mitigation Braking System (CMBS) will randomly activate without any obstacles in front of the vehicle. Consequently, increasing the risk for car accidents, loss of control, and bodily harm. The car has not been inspected by a dealer or certified mechanic for this problem. However, the vehicle is available for inspection and repair as needed. While the incident occurs, the CMBS warning system will flash ‘Brake’.
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
During a forward-side lane departure collision in my 2020 Honda Accord, the Body Control Module (BCM), forward collision radar system, braking assist, and Vehicle Stability Assist (VSI) all failed to activate. As a result, the vehicle did not brake, warn, or stabilize before impact. The airbags also failed to deploy during the crash. My safety and the safety of others were put at serious risk, as the vehicle did not respond as designed despite being equipped with these systems. The car is now undrivable but available for inspection. This issue has not yet been confirmed by a dealer due to the car's condition, but similar failures have been reported in other 2020 Honda Accords already under recall. The insurance company did not request vehicle data and did not inspect the systems. There were no warning lamps, alerts, or messages prior to the failure; the malfunction occurred without notice. I am requesting that this vehicle be added to the existing recall list related to BCM and safety system failures.
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 contact owns a 2020 Honda Accord. The contact stated that while operating the vehicle, the brakes had erroneously activated, causing the vehicle the suddenly decelerate. During the failure, the "BRAKE" light was flashing. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The contact was made aware of NHTSA Action Number: EA24002 (FORWARD COLLISION AVOIDANCE). The contact stated that the vehicle had experienced the failure listed in the investigation. Additionally, after starting the vehicle and driving forward or in reverse, there was a squeaking sound coming from the rear of the vehicle. The vehicle was taken to the local dealer who was unable to determine the cause of the failure, and informed the contact that the failure was a common issue, but the manufacturer had not issued a service campaign to address the issue. The failure mileage was 30,000.
Mileage: 30,000
False alarms (several hundred) with audio and visual warnings but no braking. ONE instance of false alarm WITH emergency braking from 55mph to under 30mph. I do not recall a false warning happening after sundown, ever. Alarms have occurred on bright days with sharp shadows, and overcast with no shadows. There always seems to be a solid overhead object being approached, overpass, railway trestle, solid bar supporting a traffic light. This is highly intermittent where alarms occurred 3 in a week, to 1 in a span of two months. The two constants I have noted are it happens during daylight hours and a substantial overhead object or structure is being approached. Alarms have been occurring since 2021 when i bought the car new off the lot.

The car brake by itself with no obstacles in the way
CMBS not working properly. The car automatically brakes without any collision risk even on a clear road with no traffic and clear weather. Have a huge risk of someone crashing the car from the rear due to immediate braking. This issue has appeared several times.
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.
While I am driving I have experienced incidents where the (Automatic Brake System) AEB system engages unexpectedly, causing the car to brake hard without any obstruction or vehicle in front of me. This incident have happened on both highways and main roads. When my car unexpectedly breaks, sometimes I get a warning That Says Brake then the car Beeps and sometimes It won’t give a warning. Today when it happened it only braked once but like I said it happens unexpectedly. (2020 Honda Accord Sport 1.5lt)
The car's automatic emergency breaking activates randomly when there are no objects in front of it. This is very dangerous as the car is often driving full speed when this happens. I have found that this happens most often when I am driving under something, like an overpass.
All of the lights on my dashboard come on every few hours and go off. Vehicle is losing power as I drive. Multiple people with this make and model have expressed their concerns of the same issue.

My blinker won't appear on the dash. My trunk won't open. My back up camera won't come on at all. Can't adjust my exterior lights, stuck on the dimmest setting and can't change. Lights will also flicker and I have no control over it. My radio screen told me to enter a code but wouldn't allow me to. My break system light was on. There is warning reading adaptive cruise control see dealer, automatic emergency braking see dealer, lane departure warning see dealer. Doors locked and unlocked while driving. Air condition wasn't blowing the temperature it said, and acting as it was on low when it was on the highest setting. It is available for inspection upon request. I brought my car into a Honda dealership today. My car had to stay overnight because they were unable to address the problem. There were no prior problems or warnings beforehand. All these problems first appeared when I started my car for the first time on November 14, 2024. These put myself and others at risk because the doors locked and unlocked which could have caused us to get trapped in. The lights not working put me at risk at night because I could not see the road that good.
Have taken my car to dealership 3 separate times for all warning lights illuminated. Last time they replaced the transmission for a CVT belt prematurely breaking and all codes went away for one day. Now all are present again. Emmisions system warning, lane departure warning, cruise control warning, exc. Every single light never goes out. Just spent 6k on a car that had under 100,000 miles because I was told it was the transmission belt only to come home and have the exact issues happen. The day it was taken to the shop, it stalled in the road and almost caused an accident on a major highway. At this point, I'm afraid to drive it.

The automatic emergency braking system malfunctioned on 7/18/24. I was driving approx. 20 mph on a local road and there was no vehicle, pedestrian, or other object in front of the car when unexpectedly the orange warning to brake came on and an instant later the car braked on its own and came to a complete stop in the middle of the road. Given the sudden and forceful stop, I went forward into the seat belt. Fortunately, there was not a vehicle behind me as I would have been rear ended putting both me and the people in the other vehicle in danger. I reported the incident to the dealer using their online system (I wanted to do it in writing, but could not find a direct email address), but have not heard back from them yet.
I was driving along the NJ Turnpike at approximately 65 miles an hour when the brake warning light started flickering on and off and then the brakes engaged. It was quick, as if I had stepped hard on the pedal. No vehicle was in front of me, but I was driving through the express EZ Pass lane. Later that same day, it happened again, but this time it was only as if someone tapped on the brakes. The brake light flashed then too. To answer the above questions: What component or system failed or malfunctioned, and is it available for inspection upon request? The Collision Mitigation Braking System, and yes it is How was your safety or the safety of others put at risk? Someone could have rear-ended me Has the problem been reproduced or confirmed by a dealer or independent service center? No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No 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 warning flickered on before each instance

The collision mitigation braking system periodically activates when traveling on interstate highway when there is nothing in the roadway to cause this function to activate, causing the vehicle to stop suddenly then release which have caused potential rear-end accidents and possible injury to the driver r passenger due to the sudden stopping motion which propel the driver and passenger forward quickly without any warnings. Recently an warning error appeared to verify this malfunction. Which before 6/30 the warning error never appeared.
I was driving on a road that the car has been on hundreds of times. Flat, straight, dry road with no other cars around. The car all of a sudden braked very hard and the "BRAKE" light started flashing and beeping for about 3-4 seconds and then went off and then the brake fully released. It was like hitting an invisible wall and fighting to maintain control of the car at the same time. It came out of nowhere and was so shocking. There was nothing around me and no reason for the AEB system to be used. I can't tell you if my foot was pressing on the gas or had lifted to maintain speed. I do know that my foot was on or lifted above the gas pedal and nowhere near the brake. I am shocked it didn't cause an accident but I am guessing that is because I held tight to the steering wheel and possibly because there were no other cars around. I have severe whiplash, a major headache, backache and am very scared driving the car should it happen again. I have not gone to receive medical treatment yet but it is highly likely that I will need it. I will be contacting the dealership as well to discuss.
I've owned the car for over a year now, bought it for my daughter. 3 times the emergency braking system has gone off while driving for no reason. the last event happened while driving on a Hwy at 55 mph with no in front of her. The car slammed on the brakes, and the brake warning light went off, thankfully no one was behind her.
On [XXX] I took my elderly mother to physical therapy and the car began to randomly brake although there were no vehicles in front of me. The braking light flashed and then car brakes on its own. A week later I was driving approximately 55 mph on a major highway and the car started braking again but without the warning light. Again, there were no cars anywhere around me. The next day I went to the Honda dealership in Covington, LA because I am very concerned this will happen again unexpectedly when there are cars around me and it will result in a bad accident injuring myself or others. I was told he can keep my car all day but he said they probably could not recreate the issue so its just a waste of time. He said nothing he can do about it. That's just how it is and maybe it was from a bug passing the sensor. I know have to remember to turn off the feature every time I drive because I am terrified that it will randomly brake again and it may cause a serious accident.

Vehicle engaged emergency brake by itself. Also in regards to current fuel delivery recall, Honda has yet to fix my recall saying they have not come up with the parts yet. This is my only vehicle that I bough to commute to work of 150 miles a day. The car stalls on the highway becoming more often than not and is hard to start sometimes.
This car brakes while we are driving while there is nothing in front. was reported to the dealer, they can not find the issue unless the carb does it, or I can turn off the program, but that is not a safe move.
Open highway traveling 50+ mph, changing lanes from middle to right. Car's emergency brakes turned on and slowed me down abruptly for about 1 full second. Thankfully no on was behind me and no one was hurt. I have had this car for 6 months and this has happened 2 other times.

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 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 NHTSA 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.
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
Hi, My Honda Accord Sport 2020 1.5T got 3 of 4 fuel injectors malfunctions and led to all warning lights turn on.

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.

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 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.

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.
The contact owns a 2020 Honda Accord. The contact stated that while driving at various speeds, the tire pressure warning light and brake system warning light illuminated. The contact stated that the driver assists cruise control system, emergency brakes system, collision prevention system, and electrical steering assist all failed at the same time. The contact stated that the safety assist features became disabled but returned after the vehicle was restarted; however, the failure recurred. The contact stated that the failure occurred more frequently. The contact took the vehicle to the dealer however, the mechanic was unable to duplicate the failure. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 68,000.

I was driving at a slow speed (10-15mph) when my brakes automatically engaged. After the car stopped I began to accelerate and the brakes engaged again. There wasn’t any reason for the brakes to engage.
On 3/24/22 while driving on the freeway at 65mph my car stopped suddenly. The ABS alert appeared on the dashboard and it made me swerve my car, also in the afternoon when getting off the freeway the ABS system alert appeared and my car braked suddenly there was no car or person in front of me at that time either it stopped so hard the car behind me had to swerve.
I experienced phantom breaking while driving to work on 03/02/2022. I was driving on the right most lane before entering into north bound 101 highway when my 2020 Honda Accord Sport 2.0T abruptly stopped, there was no car or object in front of the car, and luckily there was no car behind me, otherwise I would have been hit and injured. A few days later, I brought the car to Capitol Honda dealer for checkout, but dealer could not find any problem. I have not driven my Honda Accord much during the past two years as I mostly work from home due to Covid-19 and my car has only 2800 miles when this incident happened. Since this is the 1st time I encountered phantom breaking, I would like to report the incident as I am concerned that it might happen again in the future.
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.
Five times over two years, the collision mitigation system has activated while the car was in motion but no object was in front of the car. Three minor activations, meaning a brief yellow glow on the dash, have occurred. Two more significant activations have also occurred with a yellow rectangle on the dash with the word BRAKE visible. The most serious activation was at highway speeds. I was concerned that the car was going to automatically brake on the highway. I have returned this two year old car to the dealership multiple times for evaluation and have found little motivation on the part of the dealership to deal with this problem and other more minor problems the car is demonstrating. I consider the above complaint to be potentially life-threatening. I will not drive in this car unless the collision mitigation is turned off.

With seemingly no impediments ahead of it our 2020 Honda Accord will suddenly brake forcefully when changing lanes or exiting the freeway. it is not constant, but it is scary since there is no reason to brake at this point. this could cause us to be rear-ended the thing this system is supposed to keep us from doing. the dealer says unless it occurs when they drive it, unless, unless. The 'advisor' said he had heard of a few examples. they are all over the internet. What is being done to address this issue? oh, and he mentioned that we could always turn it off. we bought this car because being in our sixties and reflexes not necessarily being what they once were we wanted to avoid hitting someone from behind. this has happened on dozens of occasions. the listed date was the last.
Both my wife and I have multiple dates and time experienced issues of CMBS Collision Mitigation Braking System, we would be driving with no traffic near us or with in hundreds of feet in front of us that the system would flash "brake" on the dash and then start slowing the vehicle down. Also the Front and rear brakes pads and rotor have been replaced under 6000 miles on the vehicle
THE AUTOMATIC BRAKING SYSTEM WAS ACTIVATED WHEN I WAS DRIVING ~40MPH ON A STRAIGHT HIGHWAY UNDER CLEAR WEATHER CONDITIONS WITH NO CARS IN FRONT OF ME. FORTUNATELY, THE CAR BEHIND ME WAS ABLE TO AVOID ME BUT I DID RECEIVE A FEW HONKS AND A COUPLE OF FINGER SALUTES. I IMMEDIATELY REPORTED THE PROBLEM TO MY DEALERSHIP AND STILL HAVEN'T HEARD FROM THEM - 4 HOURS AND COUNTING.
