Automatic Emergency Braking Problems of Honda Accord - part 1

This Honda Accord sport se has had electrical problems from the day I received the vehicle. Every time I went for an oil change at bommarito Honda I mentioned it to them and they said “yeah the new Hondas do tend to hand a lot of those electrical problems” so with this the problems continued to get worse. Sometimes the buttons do not work, sometimes they do, sometimes the lights don’t work and sometimes they do and sometimes the safety features and break system automated itself. I have slammed my head on the steering wheel on multiple occasions. I believe this needs to be looked into because the malfunction of the car falsely reports danger and caused an accident. Yes every time it malfunctions it flashes briefly and so quickly on the screen .

The body control module has gone out on my 2021 Honda Accord. Yesterday, when it went out, it affected all adas features, in addition to key functionality of the car.

February 13th at 1256am my emergency break light flashed on my dashboard and beep for me to break but there was nothing in front of me. I was going 60mph on route 42. Roads were clear and there was no traffic.

The multifunction adas camera module failed due to "internal error" at only 9 years old. This means that critical safety systems such as automatic emergency braking/lane keep assist malfunctioned and could not assist with avoiding collisions. I took the car to the dealer and they confirmed the issue, and charged me $2000 to fix this critical safety system. I noticed that the new camera assembly has an updated part number, indicating that Honda might have been aware of this failure issue. I have also seen some forum posts online of others having this failure with their 2016-2017 Accords with Honda sensing. Therefore I believe this should warrant a recall. When the failure first occurred upon vehicle startup a few days before I had it repaired, all these systems were disabled and there were multiple warning lamps on the gauge cluster and screen. Prior to this sudden failure, everything had been working fine as intended up until the very day it failed.

On Thursday February 5th 2026 I was driving on route 42 at 1014pm going 60mph and my automatic break light came on and beeped as I was driving down the highway. There was nothing in front of me.

My car automatically braked almost causing the car behind me to rear end me for no reason.

I was driving on the freeway doing about 65 to 70 mph and all of a sudden on the dashboard a large orange brake light came on and the vehicle hit the brakes automatically almost causing an accident. I took it to the dealership and all they did was reset some computer board but said they couldn’t find anything wrong with it. If they couldn’t find anything wrong with the vehicle then why reset the computer board.

Collision warning randomly activates when driving while no vehicles or objects are around. This has been ongoing, but this last time emergency braking activated extremely hard and would had caused a collision if there was a vehicle following as vehicle almost came to a complete stop on a 75 mph highway.

Car initiated emergency auto break while traveling on the freeway at high speed (70 plus mph) in phoenix, az for no reasons. There were no objects or cars within 500 feet, however I was approaching an overpass. This occurred multiple times on the freeway and on local roads. Reported to Honda, no fix.

There are two locations in the town I live where I am driving under a bridge, and there is a dark shadow on the road from the bridge. My car’s accident mitigation braking system turns on at these locations and suddenly brakes the vehicle. This is not safe as people are traveling speed limit around me and I can cause an accident this way. About a month or two ago, the car behind me almost hit me at one of these locations when my vehicle’s automatic braking system turned on. It was made to prevent accident and brake if there is a vehicle, but because it is braking due to a dark shadow coming, it is not working properly and needs to be looked into. I called Honda and they want me to pay hundreds of dollars at my local Honda dealership for a diagnosis, I do not feel like I should be responsible for that fee as this is a safety feature that is not working as it should and instead making it less safe for me and drivers around me.

The camera failed on the car rendering all the safety features inoperable. The camera cost almost $2000 making it an expensive repair.

All the panel lights on the dashboard lit up. Honda says I need new injectors for about $2000. The car only has about 66,000 miles. They also say a need a new head unit, for the entertainment system. I have had three other Honda Accords before this, averaging over 200,000 miles. Never problems like this.

I've had 3 phantom breaking experiences. Most recently while driving on a straight wet road (one of the other experiences the road was also wet). I was travelling at approximately 30-33 mph and the system did an automatic hard break with a perfectly clear road ahead, no cars, people or animals in front of me or on either side. Thankfully, no one was behind me either. The other wet road auto break instance was when I was traveling between 22-26 mph on a road with a slight curve and vehicles were parked on the right side of the road. I was turning appropriately to take the slight turn and suddenly the breaks slammed on. There was no danger of me hitting anything. The third instance was when a vehicle was crossing a two lane road from left to right ahead of me. Two vehicles were ahead of me in the right lane traveling the same direction I was. My vehicle slammed on the brakes assessing that we would hit the vehicle crossing the lanes. There was absolutely no danger of that happening, I was multiple car lengths back. Should this happen when vehicles are traveling behind me, it could cause a very bad accident and it would appear that I would be liable for slamming on my breaks. I will begin trying to disable this safety feature whenever the roads are wet and make an appointment to have the dealer inspect the car. This has not been inspected or confirmed by anyone at this point. When this occurs, there is no warning - just slams the breaks and a "break" warning with alert tones appears in the dash. No other warning lights or malfunction lights are on in my dash display. The vehicle is available for inspection with advanced notice so that I can make arrangements.

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. This one happened at 520pm, I was doing 45mph and my break warning light came on. The road was dry, there was no traffic on the road, and no cars or debris in the road either.

All dashboard lights are on & will not go away!.

Upwards of a dozen times my Honda Accord will suddenly brake as it believes I am about to have a collision whereas it is typically a shadow. This happens when going under bridges or overpasses, or depending on the glare from the sun. This has happened several times on the highway causing multiple near collisions at high speeds. This is extremely dangerous and requires an adjustment or recall. I have had this part stolen and replaced through a Honda approved repair shop yet the issue persists.

Vehicle: 2017 Honda Accord ex mileage at incident: approx 30,000 date of incident: Dec 10, 2025 description of problem: while my daughter was driving our 2017 Honda Accord ex, the collision mitigation braking system (cmbs) suddenly activated without warning. The car slammed on the brakes even though there was no obstacle in front of her. This caused the vehicle to skid, but fortunately there was no collision or injury. There were no diagnostic codes found when inspected by an independent auto shop. The shop advised us to temporarily disable the cmbs system. This appears to be part of the ongoing issue of phantom braking in Honda vehicles, which has been reported by many owners and is currently under NHTSA investigation. I am concerned about the safety risk, especially since my daughter drives this car regularly. Safety concern: unexpected braking at highway or city speeds could easily cause a rear-end collision or loss of control. I request that NHTSA investigate this incident and ensure Honda provides a permanent fix or recall.

Inadvertent automatic emergency braking collision mitigation braking system automatically activated even there is no obstruction while driving.

The contact owns a 2020 Honda Accord. The contact stated that while driving at an undisclosed speed, the brakes independently activated, and the transmission independently shifted into neutral. The contact stated that there were no other vehicles nearby. The brake warning light illuminated. The dealer was made aware of the failure. The contact was advised to clean off the sensors and see if the failure reoccurred. The contact stated that she did not want to see if the failure would recur. The contact was informed that the repair was not covered under the recall. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 59,660.

While driving the automatic brake system randomly starts flashing brake across the instrument panel and begins to brake the car. This does this while there are no other vehicles or any type of obstacles near the vehicle. It also, does it at random caution lights for the fire department on a 4 lane divided highway. There is no way to stop it from doing so. This happens frequently and leaves the driver with no control over the braking system.

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.

While driving, my 2023 Honda Accord hybrid suddenly experienced a multi-system failure affecting: road departure mitigation system tire pressure monitoring system (tpms) vehicle stability assist (vsa) hill start assist electric power steering system brake system (“brake performance may be reduced”) all warnings appeared within seconds. The vehicle is available for inspection, and the incident is documented with multiple photographs. In addition to the system failures, the vehicle unexpectedly began to lose power while I was driving, causing it to slow down rapidly in active traffic. This created an extremely hazardous situation, including: risk of being rear-ended since my vehicle slowed without warning reduced steering assist reduced braking performance loss of stability control inability to accelerate out of the way this combination could easily have caused a serious collision. I later learned that there is an active recall related to the systems that failed on my vehicle. However: I never received any communication from Honda, no letter, no email, no notice of any kind. I am extremely unhappy and frustrated about this. Had Honda informed me of the recall: I would have scheduled service immediately I would not have driven the car under normal conditions I would not have been exposed to this dangerous situation on the road the absence of recall notification directly contributed to my being put in a potentially life-threatening situation. A recall notification exists for a reason which is to prevent exactly the type of failure and danger that I experienced. Honda’s failure to notify me removed my ability to take preventative action. The issue has not yet been diagnosed or confirmed by a Honda dealer. I will be taking the vehicle in for inspection as soon as possible. No inspections have been conducted yet, but I have full photographic documentation from the moment the incident occurred. No prior warning lights, symptoms, or error messages occurred.

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.

The contact owns a 2020 Honda Accord. The contact stated that while driving at various speeds, the automatic emergency braking system erroneously activated, causing the vehicle to abruptly stop in the middle of the road. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure, and the vehicle was not repaired. The contact stated that the failure had occurred on several occasions. The manufacturer was not contacted. The contact was informed of NHTSA action number: ea24002 (forward collision avoidance); and related the failure to NHTSA action number. The failure mileage was unknown. The VIN was not available.

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.

I purchased a 2022 Honda Accord sport 2. 0 in 2023 with less than 100 miles at the time of purchase. To this day it has 15,005 miles, I comply with recommended maintenence, however the car has been trying to kill me. I purchased Honda care along with numerous other extended warranties. Mind you I paid for the entire car in cash. While driving, the car randomly slams on the breaks when no one is on the street and it also does in the middle of traffic. There have been several instances in which I have almost been rear ended because the vehicle slams on its breaks without notice. This happens even when the break assist is turned off. I turn it off everytime I start the car but it turns itself back on while the car is motion. One morning on my way to work there were no cars (5am), there was nothing in the road and the red brake dash light flashed then the car slammed on the brakes. I was traveling about 45-50 mph and the car abruptly stopped. I sustained multiple bruises from the seat belt shoulder strap and lap belt. I have previous chronic back issues that were aggrevated by this incident. I am still under a physicians care for my back issues (unrelated) but I do believe this occurrence aggrevated these issues even more. I did not want to make a huge deal out of this however the vehicle continues to slam on the brakes without notice and I am fearful that I will injure myself, my grandson, or someone else as a result of a defective vehicle. I took my car to Honda today 1/14/2026 and they were absolutely no help. There was no consistency when I was told how they could diagnose the problem & no time frame was given. There is nothing I could have done in order to make your automatic breaking system fail when Honda is the only one that does work on my car. I requested to speak to the gm curtis hensley and that request was ultimately denied. Honda care said the dealership could loan me a vehicle and the dealership said I had to rent it plus pay $180 diagnostic fee.

I purchased this used vehicle. I have never received any recall information on this vehicle. The electric power steering system, tire pressure and the vehicle stability assist indicators lit up after a successful vehicle inspection was conducted Thursday 11132025. A 2023 recall, identified by the NHTSA as 23v-430, covers the issue and requires dealerships to replace the vsa modulator. I contacted the dealership and they told me they could not assist.

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.

Vehicle will sometimes automatically emergency brake with nothing in front of it.

I was driving northbound in on i15 in salt lake city when a home depot bucket blew into my lane. I slowed down to change lanes when the collision mitigation braking system (cmbs) deployed without warning, bringing my car to an almost stop causing a semi tractor trailer to hit me from behind.

Car won't crank lights on dash on. Keep saying abs braking system.

Am reporting a problem with the forward collision warning and automatic emergency braking system. The vehicle has repeatedly given collision warnings and applied braking when there was no vehicle, person, or obstacle in front of me. I purchased the vehicle used in July 2023 with approximately 30,000 miles. It now has approximately 108,000 miles. Over the time I have owned the vehicle, this issue has occurred about ten times while I was driving. Four of these incidents happened recently with a passenger in the vehicle, which confirmed the issue was not driver error. In several instances, the system gave rapid warning beeps and then applied braking even though the road ahead was clear. One time this occurred at highway speed with no traffic in front of me. Another time it occurred on a lightly traveled local road with no visible hazard. The braking was sudden and unexpected. On one occasion, a leaf may have passed in front of the sensor, but the majority of incidents occurred with no visible trigger. There were no warning lights or messages before the events, only the collision alert immediately followed by braking. This behavior creates a safety risk because the vehicle can brake unexpectedly without an actual obstruction, which could lead to a rear end collision or loss of control. The problem has not yet been inspected by a dealer or manufacturer.

All vehicle assistance lights on such as e-break, vsa, mitigation system, and cruise control show up as faulty. Infotainment system goes off on its own as well. Very bad electrical parking break light always shows up when vehicle starts. Taking it to dealer multiple times they claimed it’s ok.

I was traveling on a two lane road at approximately 40 mph when the automatic braking engaged for no reason, bringing the car to almost a complete stop. There were no other cars from either direction.

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!.
