Automatic Emergency Braking Problems of Honda Accord - part 2

My car slammed on its own brakes hard out of nowhere with nothing in its forward. The first time it happened was about 9 months ago while I was driving on the highway, it was a quick moment of breaking without any reason, but the car didn't stop. Today it happened again, the speed was about 30 m/h, the car slammed hard on the brakes to an almost complete stop. I was lucky, nobody was behind.

Emergency braking system engaged for no apparent reason with no other vehicles on the road. Potential for rear-end collision. This was the first event. Personally inspected forward looking sensors / camera for blockage, none found. Did not notice any messages or warning during the event. Wasn't looking at the dash during the event.

Driving down the road, no cars or obstacles in front of me. Out of nowhere the automatic emergency breaking came on. The car slammed on the breaks and very quickly came to a complete stop in the middle of the road. If there happened to be another car behind me they would have rear-ended me. There were no warnings prior to this happening.

Lights go crazy in dashboard apparently due to constan cylinder misfires, spark plugs changed, same issue, fuel injectors and coils changed, same happened keep it getting fix and the problem persist, making the car dangerous to drive, since it loses power since the car it’s not able to respond and work as it should be having engine, steering and brake issues, problem has been confirmed by dealer. It hasn’t been inspected by manufacturer. The lost of power and acceleration it’s probably one of the symptoms before all the light go on again. It’s been several times that this happens and I know for a fact that many people are experiencing this issues due to turbo or head gasket failure. Might get that inspected soon.

I bought this 2019 Honda Accord on June 30th from a company called greenville motor company. July 1st, I took the car to the Honda dealership to get a diagnostic to make sure everything was in good shape. The technician I spoke with did notice the car & stated that it had a problem with the previous owner which was the injectors. She told me that the light may not come on now but it may come on in the future. After I left the Honda dealership, I went to greenville motor company & showed them the diagnosis I had done at Honda. He said he didn't see anything wrong. On July 2nd, all of my dashboard lights came on. Took it back to greenville motor company, the tech there said I could pick it up July 3rd & drive it over the weekend. (basically he reset the lights so they wouldn't come on for a certain period of time). Within this time period I took it back to the Honda dealer & they told me that I also needed a turbo, they gave me the printout for that as well. Took it to greenville motor company, they agreed that I did. Need a turbo. Manager says he ordered turbo. I I don't remember the date I took it back but on July 12th, my dash lights came on again. I took it back to greenville motor company July 14th, July 18th greenville motor company called & said something on top of the turbo wasn't screwed on thats what was triggering the turbo code to show, so he never put on the turbo that he ordered I had it 2 hours & my dash lights came on again.

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.

When I am driving in an area near my home with road construction- there is a certain area that has a metal plate in the road and when I approach in from the east my car will automatically brake hard. Luckily this has not caused an accident but I suspect that it may because it is a busy road.

During interstate driving vehicle detected both road departure and engaged the emergency automated braking. The vehicle attempted to correct the "road departure" by steering the vehicle away from the perceived problem and engaged the brakes nearly causing a collision as it has done numerous times before. I have reported this to NHTSA and american Honda and await a repair of this dangerous issue. Honda has opened a case on this but have had 6 months and no response has been issued.

All lights on head dash are on , all components are not working properly or effected because of this. (engine light brake light abs light tire light traction control light , sensors out all) while driving vechile reduces power does not operate randomly , have to pull over shut the car off and turn it back on. Has high vibrations lot of shaking, stauling. I have had it looked at with multiple shops and dealer . Everybody is playing a guessing game and can not pin point what exactly it is . Was told it was spark plugs and coils, alternator , fuel injectors. All have been repaired, and still have all lights on dash and still facing every problem listed after repairs. Been inspected by manufacturer. Say not been resolved was told if it wasn’t what was already fixed they don’t know and that this is very common right now . It first started about a month ago.

Driving the vehicle at highway speeds the large orange “brake” warning illuminates and flashes, and the brake activates. This has happened approximately 5-6 times since I have owned the car. This started within 2 months of purchasing the vehicle. The dealer has tried replacing the front camera and I have changed the battery. None of this has fixed the issue. According to my innova 5610 code reader, there are 32 pending codes for the electric brake booster, including bring temperature too high, brake booster driver, circuit, overheat, brake pedal stroke sensor component, internal failure, brake pedal stroke sensor one circuit short to ground, brake pedal stroke sensor one circuit short to battery or open, brake pedal stroke sensor two circuit, short to ground, brake pedal stroke sensor two circuit short to battery or open, sensor voltage, a short circuit to ground, driver seatbelt sensor, vehicle, communication bus a performance, vehicle communication bus c performance, lost communication with the ecm/pcm a, f – can malfunction pcm – tcm, can communication failure with driving support system control unit, lost communication with vehicle, dynamics, control, module, lost communication with park brake control module, can reception error srs, can malfunction ecm/pcm gauge control, module, invalid data received – signal has too many transitions/events, invalid data received from transmission, control, module – event information, invalid data received from vehicle dynamic control module event information, electric parking brake system malfunction control module – internal electronic failure, battery voltage circuit voltage below threshold, battery circuit voltage above threshold, and control module input power a circuit open. After I changed the battery and took the vehicle to the dealer for recalibration they mentioned the pending items, but did not do anything about them or record them on their paperwork.

I purchased my Honda Accord June 21, 2024. For the first 3 months, the brake system indicator rectangle shape amber light (blinked on and off for several seconds) on 8 separate occasions when driving this car, so I brought the car to Honda dealer that concluded it must be dust on the brake for the next 3 months, the brake system indicator rectangle light (blinked amber on and off) on 6 separate occasions, the Honda dealer told me they could not find a problem with the brake, for the next 4 months,the brake system indicator rectangle light (blinked amber on and off) on 3 separate occasion , again the Honda dealer told me they could not find a problem but I noted that the dealer did not have record this on the work order. I then called Honda customer service (800-999-1009) support on June 23, 2025 at 1:17pm. I told the representative that the 2024 owners manual on page 84-85 did not have an amber brake indicator message among the 30 or so indicators in the manual. On page 493, the manual also mentions "if the brake system indicator (red) comes on or blinks, there is a malfunction in the brake system" on page 494, the manual also mentions "if the brake system indicator (red) comes on or blinks at the same time when the brake system indicator (amber), release the parking brake. The representative could not explain what a blinking amber brake system indicator meant and I should return car to the Honda dealer. Upon my insistence, my call was escalated and that a senior representative agreed that an blinking amber brake indicator explanation is not in the owners manual and could not provide me with an answer. Her best guess was that I was to close to a car in front of me (even though this has happened when there was not car in from of me). Can the NHTSA provide me with an explanation on why the brake system indicator rectangle light (blinked amber on and off) or have Honda provide the NHTSA with an explanation if this represents a dangerous situation to dri.

On June 9, 2025, my 2016 Honda Accord’s driver seatbelt detached and yanked my body with excessive force during a collision, it felt like not lifted me up to the roof the seatbelt’s jerking motion was so odd and intense causing serious injuries including a ruptured breast implant, nerve damage, and cervical spine trauma. The airbags failed to deploy despite a front and side impact. Immediately afterward, both seatbelt and airbag warning lights illuminated. The car has been in repair storage (kia willowbrook Ford) since June 16, 2025, without explanation or safety findings from Honda. Honda said the seatbelt sensor is backorder but no one can give me an eta and I need a vehiclethat is safe. The part has been on backorder for close to 5 months!! this is a critical safety failure, and I am requesting federal investigation into possible seatbelt or airbag defects associated with this VIN. ,.

I was driving on a city street at about 30mph. There was no one in front of me or behind me. Nothing in the road. The orange rectangular brake light came on for no reason, kept flashing and it felt as if the brakes were automatically being pumped, slowing the car down to a compete stop. In addition, I had no control of the steering. It was very dangerous situation which could have resulted in accident or injury.

My 2018 Honda Accord sport has been experiencing issues with its automatic emergency braking system, specifically the collision mitigation braking system (cmbs). The system has been activaing unexpectedly, causing the car to brake without an apparent reason. I’ve been trying to keep a list of locations that it has happened and it usually occurs under overpasses when the light changes from light to dark. I’ve reached out directly to Honda and the dealership and neither took my inquiry seriously.

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 6th occurrence since the first event on 21 April 2025. This occurred on the interstate. During this event, the vehicle rapidly decelerated from 45 mph to 30 mph without the ability of the driver to intervene or take back control of the vehicle. This led to a very near miss as traffic was rapidly approaching the rear of my vehicle. At the time of the incident (5:52 pm), I was in the left lane. Traffic was moderate. The weather was rainy and wet. Cmbs was off. Acc was off. 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 no warning or alert (audible or visual) lights were present before, during, or after the event.

Woke up and started my car, all the lights were on including engine light. No adapter cruise, steering light was on. Screen also was saying avoid speeding. Every notification was telling me go to the dealer ship. I took it howdy Honda in texas and they said we will need to do a diagnostic and it was for 255 for to see what the problem was. They looked and said I had code for po172(rich) and misfire on p0301 told me I need to replace fuel injectors. Which cost 1933$. Which is way too much and fuel injectors a labor should be covered under federal emissions warranty but they said no. So I am filing a recall for fuel injectors for my 2022 Honda Accord sports se. I am unable to drive because it’s in limp mode. I also have documentation from howdy for quote.

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 car brake by itself with no obstacles in the way.

Vsa/abs module has gone bad. Loss of emergency braking.

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.

The automatic braking system will alert/engage when going down hills, despite there being no traffic in the road. The blindsplot warning will also alert when there is no traffic.

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.

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.
