2020 Honda Accord FORWARD COLLISION AVOIDANCE

Open highway traveling 50+ mph, changing lanes from middle to right. Car's emergency brakes turned on and slowed me down abruptly for about 1 full second. Thankfully no on was behind me and no one was hurt. I have had this car for 6 months and this has happened 2 other times.

The contact owns a 2020 Honda Accord. The contact stated while driving at an undisclosed speed with no other vehicles nearby, the Forward Collision Warning system activated briefly, applying the Automatic Emergency Braking. The vehicle returned to normal functionality, but the failure became a regular occurrence. The brake alert warning light was illuminated. 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 Warning). The manufacturer was not notified of the failure. The failure mileage was 54,000.

Collision mitigation message turned on, took it in to dealer and they said sensor was coming up as malfunction and not aligned so they aligned it. Although sensor was aligned emergency brake still brakes without an obstruction in front. It has happened on interstate highway at speed limit where speeds are at 75mph.

The hand/emergency brakes activated without me doing it while driving and had stayed on ever since. I had my mechanic look into it and he mentioned may be due to a defective sensor and advised to have the dealer look into it for recalls. I saw that the NHTSA is actually reporting on a similar issue. The car still has good brakes (pads and rotor) however the issue continues as it will randomly activate the emergency brakes.

CAR EMERGENCY BRAKING SYSTEM ACTIVATES WITH NOTHING IN FRONT OF ME THIS HAS HAPPEND TO ME 3 TIMES TODAY IT SLOWED ME DOWN TO A COMPLETE STOP ON THE INTERSTATE AND TOOK A FEW SECONDS TO DISENGAGE WITH CARS SWERVING AROUND ME TO AVOID COLLISION THIS IS A MAJOR ISSUE

The collision mitigation braking system periodically activates when traveling on interstate highway when there is nothing in the roadway to cause this function to activate, causing the vehicle to stop suddenly then release which have caused potential rear-end accidents and possible injury to the driver r passenger due to the sudden stopping motion which propel the driver and passenger forward quickly without any warnings. Recently an warning error appeared to verify this malfunction. Which before 6/30 the warning error never appeared.

Vehicle was being driven at 38 mph on a road with no other vehicles, bicyclists, pedestrians or other obstructions in sight when the "BRAKE" warning flashed on the dashboard and the brakes were immediately engaged, causing a hard stop. Had there been a vehicle following, it is likely that a rear end collision would have occurred.

The contact owns a 2020 Honda Accord. The contact stated that on several occasions while driving at various speeds, the Forward Collision Mitigation Braking System notification message displayed, and the brake pedal was depressed but the pedal remained on the floorboard. The contact stated that the vehicle decelerated from 65 MPH to 15 MPH before abruptly stopping. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 55,000.

I was driving on the freeway when the car started to break on its own and also indicting to brake as if there was something in front of me too close. But there was no car in front of me or beside me. The car breaking on its own was a major safety hazard since I was on freeway and driving about 65 mph. If a car would have been right behind me I would have been rear ended. I did take car to the dealership and let them know what had happened. And they told me I would have to take car in for a diagnostic appointment and the problem would have to happen while tech is driving car so they could look into it. This has happened to me a total of 3 times.

As I was driving down the main road at 45 mph, no cars, animals or people anywhere around me, my 2020 Honda Accord Sport automatic braking system HARD BRAKED out of nowhere for no apparent reason! Thankfully there were no cars behind me or there would have been a crash!

Automatic 45mph to zero breaking with no cars or objects in sight. Almost caused a rear end collision due to faulty and unnecessary automatic breaking.

Three times in one day the emergency braking system has gone on automatically for no apparent reason. We were not at risk but are concerned we will be put at risk. There was no warning. We have not taken it in but will do so asap

With seemingly no impediments ahead of it our 2020 Honda Accord will suddenly brake forcefully when changing lanes or exiting the freeway. it is not constant, but it is scary since there is no reason to brake at this point. this could cause us to be rear-ended the thing this system is supposed to keep us from doing. the dealer says unless it occurs when they drive it, unless, unless. The 'advisor' said he had heard of a few examples. they are all over the internet. What is being done to address this issue? oh, and he mentioned that we could always turn it off. we bought this car because being in our sixties and reflexes not necessarily being what they once were we wanted to avoid hitting someone from behind. this has happened on dozens of occasions. the listed date was the last.

Driving on the interstate going about 60mph with no one in front of me or behind me and the car brakes by itself. This is the fourth time this vehicle has randomly brake

I experienced phantom breaking while driving to work on 03/02/2022. I was driving on the right most lane before entering into north bound 101 highway when my 2020 Honda Accord Sport 2.0T abruptly stopped, there was no car or object in front of the car, and luckily there was no car behind me, otherwise I would have been hit and injured. A few days later, I brought the car to Capitol Honda dealer for checkout, but dealer could not find any problem. I have not driven my Honda Accord much during the past two years as I mostly work from home due to Covid-19 and my car has only 2800 miles when this incident happened. Since this is the 1st time I encountered phantom breaking, I would like to report the incident as I am concerned that it might happen again in the future.

Today I was driving my Honda (Accord 2020) about 30 to 40 miles an hour and suddenly the car decided to brake for i guess a fraction of a second. It is hard to describe but literally felt that someone slam on the brakes. I also got the brake alarm and the sign on the dashboard "BRAKE" (orange sign). I was taken by surprise, even my wife asked me, what was I doing?. It was only a moment, but it was totally unexpected, lucky for me, there was no one in front or behind me.

The vehicle automatically turned on the forward collision mitigation system when there was nothing to avoid. Vehicle went from 55mph to 20mph in about 2 seconds. Fortunately there was no vehicle approaching from behind. I had no control over trying to override the braking system. Had vehicle checked at Honda dealership & was informed there was nothing they could do other than make a note of the issue.

I was driving at a slow speed (10-15mph) when my brakes automatically engaged. After the car stopped I began to accelerate and the brakes engaged again. There wasn’t any reason for the brakes to engage.

On 3/24/22 while driving on the freeway at 65mph my car stopped suddenly. The ABS alert appeared on the dashboard and it made me swerve my car, also in the afternoon when getting off the freeway the ABS system alert appeared and my car braked suddenly there was no car or person in front of me at that time either it stopped so hard the car behind me had to swerve.

The contact owns a 2020 Honda Accord. The contact stated while driving 30 MPH and accelerating, the vehicle experienced phantom braking and abruptly stopped. There was no warning light illuminated. The contact stated that the failure was experienced several times within a two-month period. The contact was able to continue driving the vehicle. The vehicle was not taken to a dealer nor an independent mechanic to be diagnosed or repaired. Neither the manufacturer nor the dealer was notified of the failure. The approximate failure mileage was 14,000.

Five times over two years, the collision mitigation system has activated while the car was in motion but no object was in front of the car. Three minor activations, meaning a brief yellow glow on the dash, have occurred. Two more significant activations have also occurred with a yellow rectangle on the dash with the word BRAKE visible. The most serious activation was at highway speeds. I was concerned that the car was going to automatically brake on the highway. I have returned this two year old car to the dealership multiple times for evaluation and have found little motivation on the part of the dealership to deal with this problem and other more minor problems the car is demonstrating. I consider the above complaint to be potentially life-threatening. I will not drive in this car unless the collision mitigation is turned off.

when I am driving, there is no car in front of my car. Brake warning flash and randomly slam on the brakes without the I touching the brake pedal.

This has happened more than one time.The first time it happened I was going down a 2 lane road no one in front or back of me and I was going 65 with my cruise set and the car slams on break and stays blink break on the dash. The second time it happened i was going down a 2 lane road at 45 no one around and it slams on breaks really hard and blinked break across the dash.

Both my wife and I have multiple dates and time experienced issues of CMBS Collision Mitigation Braking System, we would be driving with no traffic near us or with in hundreds of feet in front of us that the system would flash "brake" on the dash and then start slowing the vehicle down. Also the Front and rear brakes pads and rotor have been replaced under 6000 miles on the vehicle

CRUISE CONTROL NOT WORKING PROPERLY WITH THE SPEED AND CAR BRAKE BY HIMSELF ITS LIKE DETECT SOMETHING BUT IS NOTHING IN FRONT
