Automatic Emergency Braking problems of the 2019 Honda Accord - part 1

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

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.

Wednesday 10/01/25 I was driving to work on the highway with cruise control on, it was a empty road with nothing in front or behind me, my steering wheel got yanked out of my hands and turned all the way to the right towards the guard rail, then the steering wheel got yanked all the way to the left automatically, I did a 180 degree spin and crash my 2019 Honda Accord touring 2. 0l. I believe the lane keeping assist system (lkas) was at fault as well as the collision mitigation braking system (cmbs). The vehicle got towed off the highway directly to a local body shop. The vehicle is available for inspection upon request. Mine and others safety was put at risk because the vehicle decided to crash itself potentially killing me or other people. The vehicle just arrived at the body shop and no diagnosis has been done yet. The vehicle is not drivable so the problem has not been reproduced. Vehicle has not been inspected and looked into yet, I am waiting for the body man to do a deep dive into it or I am planning on bringing it back to the dealership. There was no warning lamps present.

Driving along at approximately 41 mph, cmbs unexpectedly activated for no apparent reason. There was no object in road to potentially collide with. Warning system barely activated before cmbs engaged braking very hard. Vehicle went from 41 mph to 31 mph in 2 seconds as recorded on dash cam. This is the 2nd occurrence in the same approximate location, both for no apparent reason & with no object in road ahead. Had an another car been following closely, this would have caused injury.

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.

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.

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.

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 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.

While driving my Honda Accord on us highway 1, six warning signs lit up in the dash. The lights are brake system electric parking brake, brake system performance, brake system hold, acc, collision mitigation system, and road departure system. The car began to brake and accelerate on its own. I pulled over for 10 minutes with the car in park. After waiting I proceeded to return driving unsafely with the warning lights on and car spontaneously braking and accelerating on its own.

1. The aeb system activated on a clear road with no visible obstacles in sight. The car showed "brake" message and braked by itself. Fortunately there was no car immediately behind me, so there was no collision. 2. While parked, with the keys untouched, the truck opened by itself. This has happened on more than one occasion.

The automatic braking system (abs) engaged suddenly and without cause to engage. The vehicle is available for inspection. The sudden stop while traveling at approximately 40 mph startled me (driver) and could have caused a rear end collision. The vehicle was taken to the local Honda dealer. They indicated I should disable the abs when using the vehicle. The actual abs system was not inspected by the dealership or any other individual. There were no warnings prior to the occurrence although the dashboard displayed the standard braking warning when the abs engages. This occurred just once at which point I have subsequently disabled the abs whenever driving.

I was driving about 45 mph about 10:45 am. Suddenly, my car braked on its own. The message, "emergency brake", flashed on the screen. This same problem happened on August 2, 2024. There was no vehicle in front of or behind me. Neither was there any vehicle beside me. I am very concerned about my safety in driving this car. I have reported this problem before. On August 5, Honda dealership did a component diagnostic check. They said they found nothing. But this problem has occurred twice now. Something is wrong. I repeat: I am very concerned for my safety in driving this car.

Car keep braking when I go under low bridges or shadows on the road from overhanging trees.

The automatic braking occurs when there are no impediments to forward motion. It has occurred on a periodic basis at least 15 times.

My car is unexpectedly braking on the highway for no reason which is an extreme harzard. It has happen over 6 times while driving unexpected. On diffrent times while on the highway and while on the regular streets at diffrent speeds. I do not see any recalls on the automatic brake system. I have only had this car for about 6 months and it has happen since I got it from carvanna.

When I am driving on the highway, sometimes my car just brakes. This has happened 7 times! I am lucky I am not dead, or I have not killed anyone yet. It will go from 60 mph down to 20 mph all of a sudden. I am scared to drive my own car.

I was driving about 40 mph when my car slammed on the brakes. There was no vehicle in front of me. There was no warning message. The word "emergency " appeared on the dashboard. This could have been a serious accident had I been on the beltway. This problem needs to be addressed immediately.

My Accord seems to trigger automatic brakes for no reason. I have noticed it happening primarily on freeways and expressways (while traveling at high speed)which is extremely dangerous. There has been only a single instance of this behavior while driving on a 35 mph posted speed corridor. My latest experience was on 6/29/24 around 10:30 am. Contacted the dealership with the issue. They said they will call back, but haven't heard from them yet.

I've had head gasket failure twice and now turbo failure. I have documentation from john eagle Honda to support as well as several others who are willing to do a class action lawsuit in regards to the 10th generation Honda Accord 1. 5 t and some of the other trims. I have a list of other owners like myself who have paid out of pocket constantly to get our vehicles fixed. My last straw for reaching out is when it stalled on me while on the interstate for the second time and almost getting in a horrible accident. Something has to be done, because at this point Honda has been called several times and acts if no one is reporting it when indeed they are. I have tons of documentation and proof to support my safety issue. I first paid for the head gasket in 2023, then again in 2024, now I'm being told the turbo needs to be replaced of which it is in the shop currently and I was quoted 1700$. Something has to be done because of this issue I have spend a lot of money and none of my safety features worked during this time, the head gasket issue shuts down everything and can cause serious injury.

Emergency front collision braking system activates out of nowhere, causing the car to suddenly brake with no warning, although there is nothing in front of the vehicle. Now all the mitigation system lights are on, and the braking system is no longer working. I took it to Honda to repair it twice within the year, and now it happened again, almost causing an accident.

The car detects something in the road even though there is nothing in front of the car. When it detects, it applies emergency brakes. This has almost caused me to be rear ended a couple of times.

This car brakes on its own . I reported it to Honda since I have had it have been dealing with the issue it brakes on its own I filled out a form with you guys after reading about “ghost braking” so I am not alone this car is dangerous it has been serviced multiple times Honda corp is aware requested a buy back. Wondering where you guys are in your investigation I have pictures the sensors are all out of whack mitigation control warnings etc but the car literally brakes on its own highway and street Honda states they cannot disable the features. I need help. Please update me occurred again today.

This is the second time it has happened with my car that the automatic emergency braking system got applied and there was no one in the front. The braking system beeped as if it was about to collide and then it braked. Today a car behind me was almost rear ended me because of this sudden braking.

My car suddenly triggered automatic emergency brake even when there is no apparent reason or no blockage ahead of the car. This might cause rear side collision.

Vehicle has applied brakes automatically for no apparent reason at least 10 times in the 4 years we have owned the vehicle. 2 of those incidents was entering a freeway under acceleration from a on ramp putting us in a dangerous situation. It did not completely stop us before it released the braking system. It has also happened when exiting the freeway onto a off ramp numerous times automatically applying the brakes when nothing is in front of us or beside us. Last time it happened was last week while driving down a divided highway with no vehicle beside me or anywhere close in front of me a car was behind me and had to slow down. My car automatically applied the brakes and slowed me down and would not accelerate for about 10 seconds then they released and I was able to accelerate back to normal speed. To not it does not slam the brakes on and lock them up but it does start to slow you down quickly before allowing you to accelerate again. In the wrong situation this could cause a accident or a string of accidents.

The car brakes hard while your driving and there is nothing infront of you without warning and hurts your stomach with the seatbelt. Also when passing over a train track the car beside me went over it and the rail got detected and made the car stop hard. I was with my girlfriend and she is pregnant and the seatbelt got stuck for a moment and since it broke over the train tracks and the force made us fly forward and the seatbelts hurt our stomach but good thing there was no accident or anyone behind me.

The vehicle will have the "collsion mitigation braking system problem. See your dealer" warning come on periodically. When the warning has been on, the vehicle has occasionally randomly braked hard. The warning typically goes off after the car is turned off.

Automatic braking occurs at any time for no reason. This is extremely dangerous. I've almost been hit from behind a dozen times when my car suddenly puts on the brakes for no reason. I submitted this information to you several years ago and never heard a thing back. This system was apparently designed for people who drive impaired/distracted who shouldn't be on the road to begin with. I drive attentively and if I need to apply the brakes I do so. When I'm being tailgated it freaks me out because I know it's an accident waiting to happen if my car slams on the brakes. I can not turn this function off or disable it. (the date below is today as this field is required. It's been happening on average once every 100 miles. ).

On Thursday November 16th at around 8:00 am I was driving down la cienega blvd going around 30-40 mph. I was about to pass a green light when my 2019 Honda Accord sport started showing the brake signal on my dash. My car suddenly brakes and comes to a complete stop by itself in the middle of the road. There were no cars in front or on either side of me, no potholes or anything of that matter that would’ve caused this to happen. I am now suffering with severe neck and shoulder pain from this unexpected incident. My 1 year was also in the car with me. My car is now being inspected at the Honda dealership where it was purchased.

I was highway driving when suddenly a brake light flashed on and off and car came to an immediate stop (then go). There was no use of the brake pedal, nothing ahead of me - and fortunately no one behind be which could have resulted in a serious crash, safety was a major risk!! husband checked fluid, car is now "awaiting" inspection at a reputable diagnostic service location. Read an article about these similar defects/complaints, but the Honda dealership claims there have been no like incidents, complaints or concerns. I read otherwise that indicated such events were under investigation (cnn wire Feb 27,2002). When I called another dealership, they explained that there were not enough complaints to warrant a (safety recall). I beg to disagree!! today's date is 11/04/2023. Thank you.

Since may or June of 2023 my car has automatically breaked at random times without coming close to anything. It has happened approximately 5 times, 3 times on the freeway when I was going anywhere from 40/70 miles an hour and twice on side streets going less then 20 miles an hour. It has caused me to think I was getting rear ended due to the brakes slamming for no reason.

Car won’t start suddenly. Message says “brake system not working contact dealer”. Then says “system initializing” then goes blank. No response at all when start button is pushed.

Car will apply brakes randomly without warning. This will happen when a vehicle is in the left or right driving lanes. Car has been to the dealer to address the issue as recently as 7/17/2023.
