2019 Honda Accord FORWARD COLLISION AVOIDANCE

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.

In 2 instances the car put on brakes for no reason. Nothing was in front of car. I was traveling roughly 70 mph and car slowed down and brake indicator came on, also going 75 with cruise control on and the system that brakes the car slowed the car down and then just quit working. Warning lights came on saying system failure but after car was turned off then turned back on there were no warnings.

During highway driving the collision system starts to brake without any risk or objects in view. Happen twice within 10 minutes

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.

Car did not slow down adaptively. Tried to hit the brakes hard and ended up needing to use the emergency brakes.

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.

The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Action Number: EA24002 (Forward Collision Avoidance). The manufacturer was not notified of the failure. The failure mileage was 19,000.

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.

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

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.

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.

Car broke abruptly. Warning messages came up on dashboard including ACC error, brake system error, collision mitigation warning.

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 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.

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.

I was driving about 35 mph with nothing in front of me and suddenly, the “brake” warning came on and the automatic brake engaged. There was a car behind me, but thankfully far enough behind that a rear end collision did not occur. I’m very concerned. I think the system is called CMBS (collision mitigation braking system). I would just as soon not have to have it!

Vehicle ACC, Lane Departure system and collision mitigation braking system all turn off and there is no recall. This has caused unwanted braking at times as well. Overall, this system is completely non-functional in my vehicle and I am seeing this issue with other people all over the internet. There has been a new battery installed, multiple attempts finding a solution and nothing on the scanner comes up. WHY HAS THIS NOT BEEN SET AS A RECALL? IT IS EXTREMELY DANGEROUS!

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 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.

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 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

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.

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.

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.
