Automatic Emergency Braking Problems of Honda Accord - part 2

It is uncertain which specific system/systems have failed/malfunctioned at this point. Despite frequent and consistent communication with Honda, no real attempt has been made to uncover the cause of this issue, and no solution has been provided. The vehicle has been, and is, available for inspection upon request. This is the 2nd occurrence since the first event on 21 April 2025. This occurred on the interstate. During this event, the vehicle's forward collision warning triggered an audible and visual alert that could not be shut off. This led to a very near miss as traffic was rapidly approaching the rear of my vehicle. At the time of the incident, I was in the left lane. Traffic was very light. The weather was dark and dry. Cmbs was on. Acc was off. Lkas was on. Rdm was on. Problem has not yet been reproduced but dealer has verbally indicated that they get frequent complaints about the system. This includes one employee who has experienced this on his personal vehicle. Many dtcs have been recovered from the vehicle’s log. Manufacturer: yes, vehicle has spent 30 days, to date, in custody of Honda police: not yet. Will do immediately if advised insurance representatives: not yet. Will do immediately if advised others: no. Any work on the vehicle performed outside of Honda east cincinnati will void the warranty visual and audible alerts were present before, during, or after the event.

The collision mitigation braking system is engaging while I’m driving with no obstructions in front of me. The car slows down completely while I’m on the highway almost coming to a complete stop. This has happened numerous times since Dec 2024. I took it into Honda and they did absolutely nothing besides charge me over $500 for diagnostic fees and told me to get an oem battery and bring it back to be inspected again.

The contact owned a 2022 Honda Accord. The contact stated while driving 68-70 mph, the vehicle stopped abruptly, causing another vehicle to crash into the rear passenger's side of the vehicle, and a second vehicle to crash into the rear of the vehicle, causing the trunk to be pushed inside the rear seats of the vehicle. The brake warning warning light was illuminated. The air bags of the contact's vehicle did not deploy. The air bags of the two other vehicles deployed. The contact stated that the rearview mirror separated and hit her head, causing a concussion. Additionally, the contact sustained whiplash, pstd and contusion on the back and on both ankles. The contact received medica; assistance. The front passenger's seat occupant of the second vehicle that rear-ended the vehicle sustained hips injury as the occupant was still recovering from a hip surgery that she had undergone prior to the collision. It was unknown whether the passenger received medical assistance. There was no property damage. A police report was filed. The vehicle was towed to crash champions, where it was totaled. The contact hired private investigators who retrieved the edr data and informed the contact the emergency braking system had engaged prior to the crash, however, the contact stated that there was no other vehicle or object around the vehicle at the time the emergency braking system had engaged. The vehicle was towed to the dealer, where the contact was informed that special equipment was not available to diagnose the vehicle based on the edr data. The manufacturer was not notified of the failure. The failure mileage was approximately 37,600.

While driving on the interstate, the car in front of my stepped on their brakes hard and immediately let off. I was several car lengths behind the car, but my emergency braking activated. The brake pedal went out of reach and I tried to step on the gas but the car would not accelerate. Two cars passed me on both sides, but luckily there was no one behind me or they would have hit me. The car went down to approximately 20 mph before I could again accelerate. The car in front of me was nearly 1/4-mile away at that point.

Several times the vehicle has automatically braked at low speeds (20-30 mph), nothing in front of the vehicle to cause this. Today it automatically braked. . . Hard. . . At 55 mph, again, nothing in front of vehicle, clear morning, road was clear. It braked so hard I'm pretty sure I have whiplash. I immediately called victory Honda. They told me to go wash my car and call them back if it happens again. The only warning it gave was the brake light and beeping, but it was instant. Thankful there was no one behind me.

While driving 2023 Honda Accord at normal speed on rural road, the vehicle began to brake on it's own and driver could not over-ride this. Alarms for multiple failures showed on the dashboard. Car was stopped and would not move. Car was turned off then restarted. Dashboard alarms went away, only small information light for brake malfunction remained. Driver began to drive and tested brakes, all acted normally. Car was brought to Honda dealership. Dealership investigated and consulted with Honda engineers. They could not find a cause of the error, so nothing was fixed on the vehicle. Honda charged owner $150 to tell them nothing was wrong, even though car had taken control of brakes and stopped itself.

Cars brake/mdoule automatically engaging. Brake light and brake system light constantly flashing. From what ive read seems to be a known issue that needs to be addressed or made a recall. This is a safety issue and can cause harm to the driver and others.

While I was driving on the freeway, the car brakes hard on its own when there were no cars in front of me. This happened twice. Thankfully there were no cars behind me either, otherwise I might have gotten into an accident.

The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, the collision mitigation system suddenly activated and applied the forward collision avoidance automatic emergency braking feature. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate e the failure. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 25,000.

I was driving when a car pulled into a driveway. My car was not near this car and the brakes stopped very hard. At other times when the brakes should have stopped they did not. I had a major accident in feburary and my safety features were on however the car did not stop when the other car turned into front of me causing total damage, broken thumb and torn ligament in my right hand.

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.

While driving on highways, with no one in front of me, vehicle will brake while I have my foot on the gas. Vehicle says brake system malfunction. When I let off the gas and push again, it'll accelerate for a second, then brake again even though my foot is on the accelerator.

I was driving on the freeway going around 50 mph and out of nowhere the car slammed on brakes so hard that it slammed me in my seat. No cars were in front or behind me. So there were no accidents that occurred from this incident. But it certainly did scare me.

Vehicle emergency braking system randomly triggered, causing me to completely stop from 40mph to 0mph in the middle of a intersection. Almost got rear-ended. No vehicles were infront of me to trigger the emergency braking system. Vehicle has not been taken to dealership yet.

Gas pedal would not engage after I rolled through a stop sign leaving me in the middle of a intersection. Causing a accident.

Automatic breaking engaged with foot already pressing down brake pedal as traffic ahead was slowing. The automatic braking was overkill that the traffic that was slowing down ahead of me was now pulling away.

While driving the vehicle, usually while passing another vehicle, it slams on the brakes suddenly and decelerates rapidly. I suspect it has something to do with how it reads it's surroundings. When it happens, which is without warning, the brake light comes on the dash. It has happened multiple times but recently it was a close call with another vehicle behind me on the interstate. Which is why I'm taking the time to report this. I have not had it inspected.

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.

Traction control/abs/brake lights turn on 122-11 vsa solenoid valve malfunction and 83-11 which causes pcm malfunction. This is a known problem with Honda vehicles and should be a recall. When this error occurs traction/abs/brake, ldw fcw are disabled. The fix for this is over $1000. 00.

Lane keep assist continues to jerk the wheel from my hands with false lane departure warnings. Especially in direct sunlight. This has been reported to you 100's of times and nothing has been done for 4 years. How many more people have to be killed and injured in Hondas before you act?.

When car has been stopped, in traffic or parking lot, the parking/emergency brake has engaged automatically (not engaged manually or intentionally by driver) and will not disengage automatically when accelerator is pressed to go forward. It is difficult to disengage the brake when this occurs. This has happened on 3 occasions. The safety risk for crash includes being hit from behind if brake engages unintentionally in traffic or on highway, or potentially sudden unintentional stopping while driving at moderate or high speeds. The issue was reported to dealer after twice occurring and full dtc check performed. Dealer says all diagnostics normal and could not identify any problems with parking/emergency brake or collision mitigation braking system. The issue has occurred one time since the dealer inspection. The red light on the emergency break switch (console) comes on when this occurs, but no prior warning lamps or messages.

Driving on town road up a hill at about 30 mph when I got a brake system warning and the engine shut off and accelerator did not work. I was able glide to the side of the road (steering worked). I turned the car off and on and was able to continue driving to my destination but the same error message was present along with several others (eg tpms, lane assist, collision mitigation). After being parked for 1 hour, I started car and there were no error messages and car functioned normally. Brought car to dealer (westbrook CT Honda) and they ran diagnostic codes but found nothing other than what they described as an older voltage flux. They had never heard of a car's engine shutting off with the break system error. Told me that if it happened again to have car towed in so that there would be no code resets. I can only imagine my fear level if this had happened at 65 mph in the middle lane of a highway! I found a on-line forum where others are describing the same thing. Time for a recall?

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).

While driving my 2013 Honda Accord sedan on the turnpike, I experienced a critical failure of the vehicle stability assist (vsa) modulator, which was later inspected and confirmed to be malfunctioning by a Honda service technician at south motors Honda. This component is available for inspection upon request. As I was traveling at approximately 65 mph, the abs (anti-lock braking system) malfunctioned, causing the brakes to lock up when I attempted to slow down for traffic ahead. This sudden loss of braking control put my safety and the safety of others at significant risk, as I nearly collided with the vehicle in front of me. The problem has been reproduced and confirmed by an independent service center. The vehicle has not been inspected by the manufacturer, police, or insurance representatives. Prior to the failure, several warning lamps, including the vsa, abs, and brake lights, illuminated on the dashboard. These warning lights first appeared about a week before the incident, but I was unable to get the vehicle serviced immediately due to scheduling constraints. Additionally, the front collision warning system was not functioning, which further compromised my ability to avoid a potential accident. This malfunction was particularly concerning as it failed to alert me to the rapidly approaching vehicle ahead, exacerbating the dangerous situation caused by the abs failure.

I was traveling down the road and I passed a bus that was in the right lane. I think when I reached the bus shadow that’s when the automatic brake warning came on and then my car went from 50 to 15mph instantly tossing everything in my car and hurting me neck.

While traveling at approximately 30-35 mph, my vehicle suddenly and abruptly stopped, flashing the word "brake" on my dashboard. I was traveling in the right lane on a four lane road, with no vehicles in front of me or to the left of me. There were no pedestrians near, the road was free from any hazards and the road ahead was clear of any potential hazards that may require an abrupt halt. I was properly restrained, but my safety and the children I travel with could have quickly become compromised if hit from behind. Additionally, everyday items such as my school bag, water bottle and my children's books that I keep in my vehicle came flying forward, obstructing my ability to properly operate my vehicle. Additionally, being that this was unexpected, I was pretty shaken up which compromised my ability to safely operate my vehicle while attempting to find a place to park my car. My vehicle was not inspected and I used my owners manual to turn my collision mitigation braking system off in order to safely arrive at my destination. Additionally, there were no warning signals or messages that indicated this issue before it happened.

Car slammed on the brakes with no apparent obstruction in the path of the vehicle. Braking caused hand injury from the grip of the steering wheel. Nearly caused rear-end collusion with vehicle follow behind us.

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.

At approximately 9:20 a. M. On November 20, 2024 while driving at approximately 27 mph the collision mitigation braking system (cmbs) on my 2022 Honda Accord hybrid activated, bringing my car to a near halt while driving on a clear road in perfect visibility. At the time of the incident there were three pedestrians and a dog present on the sidewalk approximately 5 feet to the right of the roadway. Traffic on this particular stretch of road was relatively light at the time of the incident. No collisions occurred, and no individuals were injured. However, on a normal day there will be numerous other vehicles driving in the same lane, which would likely result in a rear end collision should this problem recur. This incident occurred without any prior warning or other symptoms. The vehicle's cmbs has not yet been inspected by the manufacturer or any other parties.

I just got off the freeway and coasted down the off-ramp, did not engage the brake nor the acceleration pedals. Suddenly the emergency brake system slammed on the brakes, it slowed me down from about 50 mph to around 20mph. There were no vehicles in front of me for at least 100 yards. It almost caused an accident by the people who almost slammed into the back of me.

Suddenly slows down without any reason while lane changing or at stop sign. It is a safety issues.

I was driving in between 40 and 50 miles per hour and the automatic braking got activated automatically for a few seconds. The road was clear and there were no vehicles or obstacles anywhere. It was about 9. 15 am and approx temp was 40 f. This is the second time it occurred. The car is not under factory warranty and the dealer would be charging diagnostic fees and unlikely to find anything wrong.
