Collision mitigation system does not work; initial issue was warning systems went on with no one in front of car. Second time brakes were applied to vehicle with no one in front of car, leading to car induced panic stop on road, thankfully, no one was trailing my car at that time. Honda test drove and could not find anything; since this is sporadic, this was not surprising. Told them it is a very dangerous condition and that this is a well documented complaint on websites; they told us we can turn off front mitigation collision system each time we drive. Requested dealership general manager to report this condition to regional director at Honda

My 2018 Honda Accord sport crash mitigation system is not working correctly at highway speed with no vehicles around the brakes apply hard at times taking the car from 65 miles an hour down to 40 mph in just a few seconds on one occasion I almost got rear ended by a tractor trailer Honda says there's nothing they can do about

My 2018 Honda Accord braked spontaneously for no reason. The word brake appears on the console and the car engages the brakes suddenly and forcefully. I've had several incidents and there were no vehicles or objects in front of my vehicle. During two episodes, I was driving 40 mph when my car braked spontaneously- it caused my head/neck to jerk forward. Fortunately, the vehicles behind me did not tear end me. I called the dealership. They said the brake mitigation system engages when driving through construction zones and told me to turn off the system in construction zones. He said 'that's how the system is designed to work'. I was not in a construction zone. This is extremely dangerous. It appears Honda is aware of the problem and is not taking steps to correct it.

I was turning right into the parking space for my car at my home with my foot resting on the brake pedal and going at a very slow speed. Then suddenly the car accelerated on its own. I had to step hard on the brake, which made it veer to the right. I was able to make the car stop just short of hitting our other car. This happened once before about a month ago when I was driving in my driveway, again at a very slow speed, this time going straight, when the car accelerated for no reason. Again, I was able to stop the car by slamming on the brakes.

Multiple errors involving vehicle's collision mitigation braking system (cmbs). Cmbs system fails regularly (approximately every 120 miles of driving) during routine use at freeway speeds. System failure shuts down adaptive cruise control (acc), collision mitigation braking system (cmbs) and displays error to "see your dealer".

The contact owns a 2018 Honda Accord. While driving 70 mph, the brakes seized when the brake pedal was depressed. During the most recent brake failure, the vehicle hopped a curb and the front and rear driver's side tires became damaged. The vehicle was taken to an independent mechanic for the tire repairs. The vehicle was then taken to coral springs Honda (9400 w atlantic blvd, coral springs, fl 33071, (954) 369-4679) to be diagnosed, but the failure could not be replicated. The vehicle was not repaired. The manufacturer was made aware of the failure and provided a case number. The failure mileage was 21,800.

When driving with cruise control and forward collision avoidance system enabled the car will at random times apply the breaks when there is nothing in front of the vehicle. So far this has happened during interstate driving approximately 2-4 times in the first 10,000 miles of ownership.

- Ferdinand, IN, USA

Collision mitigation braking system activated for no reason, on surface roads and highway speeds, vehicle slammed on brakes automatically, there is nothing on the road in front of the car. This has occurred numerous times. Dealerships told me that there was no registration in the warranty system because they were unable to fix the problem so no record of this problem was sent to Honda usa.

Today I was driving home, doing 45 miles per hour. This is a two lane road, there were no cars near me. Suddenly, the car beeped twice, the brake sign came on the dashboard and the car stopped violently. The seat beat locked down across me. Thankfully there was no one behind me. My neck and right shoulder are now hurting. The incident happened a mile from my home. My husband called the Honda dealer when I got home to report the incident. This is the third incident since we purchased the vehicle, but this time was a more violent stop. Each time there was nothing in front or beside the car. Thankfully, each time no other car was directly behind me.

Today 06-26-19 I was driving about 5mph out of a parking lot going very slow, I was ready to turn onto a road that is not busy at all, out of nowhere my car brakes locked violently suddenly. The brake light alert went off as well, when there was nothing in front of my. Not a car, not a person, absolutely nothing. My car stopped so hard that it jerked my neck. I have googled this and there are multiple complaints from people about this issue. I feel very unsafe & afraid to drive my car now, especially when I have to drive 60 miles on the interstate to my job. I'm not sure if other owners of this make, model and year have reported this issue. Please find out what's going on with my car.

During stop and go traffic, car braked causing the person behind me to rear-end me. This had happened one other time before, luckily the car behind me wasn't following too closely and I was going less than 30mph. A couple weeks after that while going highway speeds and wet road conditions, a warning light came on stating there was a problem with the collision mitigation braking system and to see dealer. Once that warning comes on cruise control also disengages. This warning light has come on one other time, while driving highway speeds with dry road conditions. If the car is restarted the warning resets and all systems are up and functioning again.

Car applies brakes while in forward motion. This only occurs when the cruise is set. I have noticed this happens when the sun is shining into the car. There have been a few times the car has applied the brakes, when attempting to overtake another car. Twice the car has applied the brakes when there are markings on the highway such as a school zone. I have taken the car to a Honda dealer, and they have not been able to find the source of the problem.

Have automatic braking and lane assist driving. Brakes on its own with nothing in front. Happened twice. Dealer calls it a glitch. I call it very dangerous. Police officer was behind me when it happened last. Good thing he had good reflexes and the speed limit was only 45 mph I was in the center of my lane with no obstructions, no vehicles coming from the opposite direction. Turned off the program and haven't used it since. Service department said would have to keep car and test drive until it occurred. I will do this, but am afraid they will be keeping the car for awhile because it happens out of the blue. It's happened twice in a period of two months. I have had the car for four months. Another problem..paint is spotting on car like it was hit with acid. Had protective wax put on the week I purchased it. Vehicle has 3500 miles on it. Paint also shows tons of orange peel. I paid a lot for this model. Expected more.

As I was driving approximately 35 miles per hour the car's brakes engaged violently. There were no cars in front, behind or on either side. This was the second time in less than two weeks this occurred. I took the car to the dealership and they stated nothing was wrong.

Collision mitigation, lane assist, road departure, and brake system malfunction before vehicle is a year old causing vehicle to leave roadway when using speeds in excess of 50 mph preventing vehicle from stopping, and/or causing steering wheel to "alert" you of lane departure while driving properly also causing vehicle to "steer" into side of 18 wheeler while traveling speeds in excess of 60mph for interstate travel with passengers in tow. Has happened for roughly 7,000 miles. When brought to Honda to be fixed, was told it was not covered under vehicle warranty due to having "clips" broken off of front sensor. Was accused of sensor being hit by something yet no sign of damage. Honda refused to have this fixed and simply "cleared" the alerts causing vehicle to not have use of any safety features but also not show any maintenance codes as well. Honda service manager stated something as simple as a "junebug" can cause this to malfunction and that is why customers carry collision with insurance. States alot about Honda's quality if a simple junebug can cause an entire $30,000 vehicles safety features to malfunction and a service manager not want to comply with safety standards due to some 2$ broken clips that can break by simply driving down a Louisiana roadway. What does this state about these vehicles up North dealing with snow with a sensor that sits underneath the front bumper?

Purchased new 2018 Honda Accord sport from dealership. While driving the vehicle it will brake with no warning and anything in sight. We see to experience this issue almost on a weekly basis. The vehicle is currently at the dealership for the 3rd time since March. Of course they say they can't replicate the issue and until can't do anything about it. The service manager continually try's to refer us to the owner's manual and stands firm that this is part of the brake mitigation safety system and is "normal". I have personally been driving the vehicle on the highway at roughly 70mph on a clear day with no vehicles in sight, no road construction, straight highway, not merging on or off the road and the system lock down with three children in the backseat. Most recently my girlfriend was driving the vehicle and the brake system locked down causing a gentlemen to swerve off the road to avoid hitting her in the rear end. I'm sick of hearing excuses from Honda and the dealership! this is not a safety feature, this is a very dangerous issue. I have been told by the service manger the system can be cut off but I should not have to cut off a "safety" feature on a brand new car with less than 40K miles. I have seen hundreds of complaints on line regarding this issue and I certainly hope it doesn't take someone being killed before Honda corrects this issue. I have documented six occurrences of the braking system locking down just in the past month. I have also spoke with Honda certified techs & service writers whom have all stated they're aware of the issue and no fix is currently available. If so I suggest Honda purchase this 2018 Honda Accord back!

My vehicle was in motion at 35 mph with no traffic ahead of me and one vehicle to the driver-side rear. With no obstructions in the road or traffic ahead of my vehicle for at least a half mile, the emergency braking system activated flashing a "brake" warning light on the dashboard and locked the brakes causing my vehicle to come to a quick and complete stop in live traffic. Attempts to override the system by applying pressure to the accelerator pedal failed to correct the problem. I estimate that it took between two to three seconds before the system disengaged and I was able to accelerate again to operating speed, narrowly avoiding a collision.

Three times now I have had the emergency breaks activate for no reason. No one was injured the first time as the vehicle was moving very slow. The second time this happened though, I was injured. I was driving approx. 45 mph down a busy street when the car stopped without warning and for no apparent reason. I was nearly rear-ended. Not only did this scare me, but I was in extreme pain afterwards. When the pain got worse and I developed bruising on my neck I went to see a specialist and he confirmed that I have whiplash. When I spoke to the mechanic at the dealership I was told that the sensor is just sensitive. They checked it out but offered no solution. I have kept the feature turned off since this happened. The third time it happened with the feature disabled. My son was in the car with me. We were both shaken up pretty badly. I am now scared to drive this car. Every time the dash lights up for any reason, I flinch. I have had to miss work due to the injuries that I received. I am a single mom to five kids, I cannot afford to miss work due to poor design and engineering of this vehicle. I bought this car thinking that this feature was a safety feature. It has certainly proven to be the opposite!

I purchased a new 2018 Honda Accord sport June of 2018. I have had my car into Honda more than 7 times for the same issue with the brake mitigation system. The car brakes on its own with no reason. Honda said it could be an air freshener hanging on the rear view mirror, bugs, rain, snow, and even a shadow from a bridge. They say every time I have brought it in that no errors come up in the system so they reset the computer and say it is operating as the vehicle is designed to. I have been in a 75mph or more zone on multiple occasions and the car will brake down to 40 or less in an instant. It sends everything in my vehicle flying. Honda denied a Honda buy back because they did a system update for the brake mitigation system that has not been released to the public yet. They are clearly aware of the issue and how dangerous it is but they expect me to continue to drive it. I am too scared to drive this vehicle with the possibility of injuring myself or someone else. Please remove these vehicles from the roads!

Collision mitigation braking system problem which causes the adapted cruise control to deactivate itself all of a sudden when driving in high or low speed traffic, happens on highway or regular street, all kinds of weather conditions from rain to sunshine. Very scary especially while going on I-95 in high traffic that is all moving very fast. Has happened at least a dozen if not more times and the dealership could not find a resolution. Taking it again next Wednesday 5/15/19.
