Quite simply we were driving through a construction zone that was down to one lane with monitored traffic. My wife was driving and approaching a steel plate in the road that was laid on top of existing asphalt. While slowing down to move over the plate at a slower rate of speed the automatic breaking brought the car to an unnecessary stop almost causing a collision from behind. This was super scary and alarming. Will this happen if we are going 35, 55, 70 mph?
The vehicle on two separate occasions has out of the blue completely engaged in an automatic emergency braking when there is no reason to and no other vehicles on the road. Most Recently I went to merge on the highway, there was no traffic infront of me and it was sunny and daytime. The vehicle engaged the emergency braking very aggressively and my car went from 65-35 quickly. There was a car and semi truck behind me I could see in my rear view mirror, they almost ran into the back of me. In the moment I tried hitting the gas pedal to speed back up while braking was still happening and the car would not allow me to accelerate or speed up until the ‘braking’ portion was over. This is happened numerous times going on on ramps and then randomly driving down the road, and not when there’s a reason to emergency brake. Three months ago when I got the vehicle I was driving down the highway and the system randomly disengaged and every single warning light for the braking system and Ford collision came on. I pulled over and called Honda, when I restarted the car all of the lights and everything went away. I’m in multiple Honda Accord groups and apparently this is a very common issue with these cars just wanted to add that as well
Going about 10mph down a side street when emergency brake automatically caused my car to stop but nothing was in front of me. Car came to a complete abrupt stop which jolted me forward, but then resumed driving like normal. Yes available for inspection as it has not been taken in or inspected for this problem, it only happened once. No warning message prior. If this would have happened on a busy street, it could have easily caused an accident.
Two times while driving on the highway at 75-80 mph with CMBS system on and utilizing ACC. Out of nowhere, vehicle drops speed, ACC OFF notice comes on and an alert stating Collision Mitigation Braking System Problem. See dealer pops up. . At this point, I have to quickly react to increase speed on gas pedal and avoid someone hitting me from behind. I am not able to re-engage the ACC the remainder of the travel. After turning off the vehicle, the CMBS resets and ACC is available again. This is not possible to do while driving on a highway. The second time it happened, I was changing lanes into the passing lane on left and I seriously could have been hit due to my speed deceleration. I took the vehicle straight to the dealer and the guy checking me in said they get a lot of those system errors. This is not reassuring! They ran a diagnostic, step by step the advisor said, only to say the system shows no issue. This is not acceptable to me as I do not feel safe driving. In addition, the lane keeping assist LKAS feature also malfunctions. When there are shadows on the road, my car wants to swerve and steer me incorrectly. My car also will display a giant orange BRAKE warning when nothing is in front of me. One time it braked so hard that my seatbelt locked up and everything on my passenger seat slid off the seat. Thankfully, nobody was immediately behind me because I could have been hit for the sudden and unanticipated braking.
Driving down at approximately 20-30 mph on a clear day. Vehicle in front of me was turning left and I was going straight so I veered right. Vehicle turns on orange brake sign on dash and suddenly pressed the brakes full stop. Good thing no one was behind me. Automatic braking can only be turned off via a physical button on left side and changing settings on dash. This is a frequent problem that happends atleast ones a month.
Many times since I have purchased my 2018 Accord Touring 1.5T - I have found that sometimes my car will slam on the brakes when doing a lane change. I kind of found that It will do this if I dont have my turn signal indicator on. It is extremely stressful when it does this on the Interstate doing 65 or 70 MPH's. I try to slam the accelerator to the floor when this happens for fear of getting hit from behind. If this normal or a safety defect?
I had owned a 2018 Honda Accord which I had purchased in 2019. I had owned the car for about 6 months when the situation occurred. I had been about 30-50 before a railroad track and had already slowed down to 30-35 mph at this point. My dash lit up with the word 'brake' and the brakes went on automatically. There was nothing in front of me but the approaching train track which shouldn't set off the sensing function. I had a truck behind me which thankfully didn't hit me although he did blare his horn at me due to the unexpected braking. I went home and started looking online to see if other honda owners had similar experiences. There were stories from driving down the freeway going 70+ mph and having the same issue with nothing in front of them and coming to a complete stop to people having accidents because of the braking issues, etc. The next day, I called Honda and they stated that they were aware of the issues but were not planning on issuing a recall. I called the dealership and spoke to the manager and stated that I was going to return the car that day. He asked if they could check out the brake situation and I stated if Honda knows of the issue but is not planning a recall, then what is the mechanic at the dealership going to fix? I declined his offer and returned the car that evening. When I got to the dealership, the manager wouldn't even come and face me, which was another issue. I sunk money into a faulty car that I will never see back. I went to a different dealership and bought a different brand of car. To this day, if I see another Honda in front of me while driving, I let off of the gas because knowing the braking issue that I had, I don't want to be involved in an accident if they other Honda driver has braking issues.
The vehicle gave me a warning for the emergency breaking and began to aggressively brake for no reason. This has happened to me three separate times. Case 1: There were no cars in front of me, a few cars behind but not too close. The vehicle slammed on the breaks from ~50mph to ~25mph aggressively. Thankfully I was not hit, only received a few angry honks from other drivers. Case 2: Driving on the highway at 60-65mph, vehicle slowed down to 30-35mph or so, i was afraid i was going to end up in the hospital if i caused a wreck. Cars were around in other lanes and nobody was in front of me in the 2nd lane. I got off the highway to take a few deep breaths, called the Honda Dealership in Ferndale, Michigan. Dropped my car off a few times to get it looked at, the service department was "unable to duplicate the event" and sent me on my way. I work in front camera modules/windshields releasing at another automotive company so i have experience with this item. I asked for my case to be forwarded to an engineer at honda to help explain the situation and to be connected to them, no luck. Case 3 similar to case 1, but a busier road. Distance was kept from vehicle in front, but my vehicle still decided to "break-check" the car behind me. This was a close one. Now, I typically drive the vehicle with the auto braking feature off (it may not be completely off but i turned it off from the steering wheel menu options). I own a 2018 Honda Accord EX-L 2.0t. All these cases happened around 28,000miles-40,000miles (two of three cases under warranty, vehicle was taken in 2-3 times during warranty and the last time the dearlership didn't even consider trying to find out the issue once they saw my history of already bringing it in). The front camera module camera void on the windshield was clean and clear 3of3 times, the grille had some dirt/residue 1of3 times which is what the dealership blamed it on. I have received no support for my claims, hence I am reporting it here. Disappointed...
The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.
My 2018 Honda Accord brake automatically when it’s nothing in front of me, this has happen 3 times without any car in front of me.The car behind me like to hit me because my car put on brakes automatically.
Three times now I have been driving with no obstructions in front of me and the Automatic Emergency Braking System has flashed "BRAKE" on the dash and then slammed the brakes on. One of the times, I was on the freeway going approximately 60 mph. Everything on the seat next to me went flying and my seatbelt locked, hurting me (I did not see a doctor as it was not necessary). There were no cars or obstructions in front of me. This could have caused a bad accident had someone been behind me at the time. The other two times, people were able to brake in time so as to not cause an accident. This was terrifying. I took it to our local Honda dealership and they simply said everything looks fine and maybe the sensor was dirty. My car was clean at the time on the freeway, and I don't recall if it was the other two times. I did not have my insurance or police look over the car as there was no accident and no need to contact them. But the actual dealership DID look over the car. It all happened suddenly with no warning and no need. The only "warning lamp" was it flashing "BRAKE" on the dash immediately before it slammed on the brakes each time.
When driving on the freeway (>50mph) with no obstacles visible in front of me, the Forward Collision System will occasionally cause the HUD to rapidly flash and warn me to “BRAKE”. It will display this message for a couple of seconds before disappearing. I have noticed that this has a higher chance of occurring when I am driving towards the sun.
2018 Honda Accord 1.5Turbo LX - Fuel Injector Failure at 58,600 - diagnosed at Honda Superstore of Lisle, IL. As a result car has low power, all safety features are deactivated, and emission system is malfunctioning. Submitting this issue as HONDA has had several other models with early fuel injector failure which it has recalled in the past. Please contact me if a fuel injector recall is issued for my car.
While driving 35mph and accelerating, emergency braking system deployed. The lights on the dash and audible beeps presented simultaneously. There were no other cars on the road other than a parked vehicle off to the drivers side. Vehicle slowed to around 5mph before releasing. No accident occurred. Honda dealership stated no active recalls were noted and an appointment would take several weeks based on the labor shortages.
On four different occasions vehicle applied the brakes on it’s own while changing lanes. as if there was a hazard in front, however there were no vehicles in front of my vehicle.
Backup camera quit working
Routine and ongoing false and nuisance braking warnings from collision mitigation system. Triggering of the warning is presumably a precursor to erroneous activation of automatic braking.
I was driving on interstate behind line of trucks in construction zone at 55mph. It was raining lightly. When zone ended, I pulled into left lane and accelerated to 70 mph. A semi truck in right lane pulled in front of me, I braked to avoid hitting it. I got within 1-2 car length of semi and suddenly car braked on its own. Brakes fully locked up. I tried to accelerate after car slowed a lot (down 15-20 mph) and considerable distance opened up between us. Car would not allow me to regain ability to accelerate. Car brakes remained locked up until car slid to complete stop in left lane. Car then allowed me to again accelerate. Unknown if braking indicator activated. No trouble lights were illuminated. Almost hit by vehicle behind that had to maneuver to avoid. Have noticed other issues where brakes briefly automatically apply when passing large vehicle in right lane. This seems to be happening more frequently in past year.
I had several incidents where Honda automatically brake without reason. I was driving 75mph and without reason it fully brake and bring my car to complete stop leaving cars to emergency brake. I recently had multiple occasions where it again brake automatically with nothing block in front of the car. The dashboard shows Lane Departure warning, but I am leaving my lane and it automatically brakes unexpectedly. This car must be recalled for safety of everyone on the road!!!
Certain roads on my commute have hills where automatic braking has engaged and almost caused accidents over past year. Also, vehicles crossing in front of me or changing lanes when I have full view, car has braked hard. These incidents have happened at least 8 times in past year. I shouldn't have to disengage safety in order to be safe.
Driving no other car in front of me and my car brake and Pulled to the side. Very scary with my children in the car. My car has sounded as if there was going to brake before without anything if front of me but this time it jerked and pulled to the side. Now I’m going to have to disable this feature on my car as I do not want to be in a accident by because of my vehicle defect.
Car accident head on emergency break didn’t work bad injuries.
The contact owns a 2018 Honda Accord. The contact stated that while driving at various speeds, the Forward Collision Avoidance feature engaged without incident with the brakes warning light flashing on the instrument panel. The contact had taken the vehicle to a dealer however, the mechanic was unable to duplicate the failure. The manufacturer was notified of the failure and a case was filed. The vehicle was not repaired. The failure mileage was approximately 23,000.
I am getting warnings of brake system problems including electric parking brake problem says it’s not available, brake hold system problem,brake performance reduced. Adaptive cruise control system problem, collision mitigation problem, and road departure mitigation problem. The car has slowed down on me while on the highway and side streets even when I am trying to accelerate and if I push the pedal all the way down it feels like it is fighting to stop, I’m afraid I am going to get hit from behind due to this. I just brought the car into the dealer for the recalls and mentioned these issues I initially thought the errors codes were maybe due to how cold it’s been because the entire screen also shut off on me then restarted its self minutes later. This car only has 30,000 miles on it.
I was going down the highway and my vehicle came to an abrupt stop. It was in the middle of traffic. I was in NO danger prior to this happening. I almost got rear ended from the truck that was behind me as a result of this, as I had no control over this sudden braking. The truck behind me had to swerve over or it would have hit me. I’ve only had the car for 3 weeks so far. I hope this doesn’t happen again. I’ve disabled all safety features to hopefully prevent it from happening again. The dealer from which I bought my 2018 Accord is aware of the incident. I hope the issue gets resolved soon, for all of us.
This vehicle has made sudden complete stops when there is no object or vehicle in front of it. This has occurred while being on a two lane road so no lane changing needed. It has made such a abrupt stop it has tightened the seat belts and sent a dog that was on the seat to the floor. I do alot of traveling on the highway and this could be very dangerous and cause a bad collision. Took to the dealer and was told nothing is perfect. I am very concerned of when it could happen.
Ghost braking for no reason I could be going 70 mph and it'll slam on the breaks with nobody in front of me or anything
I have had multiple instances (since purchasing the vehicle new at the end of the of the 2018 model year (Sept 2018) of my 2018 Honda Accord LX suddenly braking when there was no reason to brake. I talked with my service advisor at Dave Mungenast Honda in St. Louis, MO within the first month of taking delivery of this new vehicle about this issue and was told that nothing is saved (in vehicle memory/hard drive or other) so they would not be able to diagnose unless it had just happened prior to driving in for service. I said it was dangerous but no one was concerned (I told my kids about this and don't let them drive this car, I bought a 2022 Honda Civic also with Honda Sensing safety system (with auto braking etc.) and no issues with this car, after 8000 miles, zero issues like the 2018 Accord, none.) They said its likely just their Honda Sensing auto/safety braking system activated and its not perfect. They said if I'm still concerned and when or if it happens again feel free to drive directly to their service department (not practical, since they are not open 24/7 and often not possible to disrupt daily routine. It has happened at least 10+ times since the initial scary episode and I only have about 23,000 miles on this car (with little driving last two years during pandemic). I have had it happen in exactly the same spot 2-3 times. Whenever this happens, it's always the same, the dashboard lights up saying "BRAKE" while the vehicle simultaneously/suddenly applys the brakes, fairly hard. The brakes have never locked up completely but the auto braking is a sudden unexpected moderate to hard brake, only lasting a second or two, and then the braking automatically releases. I'm officially reporting this now, even though my events are not as recent, because I just learned other are experiencing the same issue and I believe this should be addressed by Honda and corrected before someone is injured or killed in a rear end collision.
Two times, pulling into my driveway at a slow speed, the car automatically stopped suddenly. There were no shadows to provoke this. I have not seen a dealer about this because I did not want to incur any fees. No warning, no dash lights appeared and no other messages were displayed. The first occurrence happened about 3 months ago, the second was about 4 weeks ago.
