Automatic Emergency Braking problems of the 2018 Honda Accord - part 2

Question 1. When driving the vehicle in straight line on the highway and I come up on another car in either the right or left hand lanes, sometimes (not all the time) the car breaks very slightly (but strong enough to feel it) even though there is no chance of a collision. If necessary, the systems and sensors responsible for this feature are likely accessible for inspection. Q2. Clearly, erratic and unpredictable function of an emergency breaking system is a safety hazard. Q3. I have not brought this to the attention of Honda. However, I am not the only Accord owner to observe this issue. Q4. No inspection of the system has been performed since I purchased the vehicle about a year ago. Q5. There are no warning lights or other messages presented when this happpens.

I was stopped at a light and was the first vehicle. When it turned green I started to go. I saw a short ways in front of me one of those metal plates over a hole in the road. I started to coast from 20 mph with the anticipation I would be at 10 mph when I got to it. Just before I would go over it the emergency brake system kicked in and took the vehicle to a stop. I tried to make it go by stepping on the gas but it came to a complete stop. I am thankful the vehicle behind me did not hit me.

I have a 2018 Honda Accord. I have had issues with it breaking and nothing being there. It has cause me to almost get rear ended several times and I find it to be a huge safety hazard. I will be driving down an open road and nothing will be in front of me. My car will randomly slam on the breaks and it scares me terribly. This has happened quite a few times now. At first I thought it was a fluke but it has continued to happen and is becoming a major issue.

On February 24,2024, while I was driving from st. Petersburg, FL to tampa, FL, I experienced phantom breaking on the highway. The vehicle gave brake warning and started breaking automatically. Fortunately, I accelerated and maintained my speed thus avoiding a rear end accident. I realized that there is an ongoing inquiry related to these incidents but I thought I should come forward and write to you for everyone’s safety.

I don’t know what’s going on, but I’ve taken the car to several other places to find out that the repair guys are at each and everyone as if they know that my car is going to be there is very scary is very creepy. Every last one of them works or worked for the dealership that I purchased the car and had repairs done, my car has been keyed in operable. I’m having issues with getting it repaired to find out what the repair is. I’m getting the runaround. I’m buying parts and services for things and I’m still not figuring out what’s wrong with the car at this point I feel like I’m being targeted. I would like to know the name I have filed complaints. I’ve spoken to jackie and she has not contacted me back or any of the people , that works at the Honda manufacture I can provide your proof I have some unknown trusted credentials that are popping up. I’m not sure if all of this happened after they did the tv broadcasting thing back in October, but I am very much aware that there’s something going on and I am unable to figure it out and these people that work at the dealership are not wanting to fix the problem because I’ve already filed several complaints with them, I just wanna get my car fixed or at least know what’s wrong with it.

Fuel pump recall. Put in an order with Honda dealer January 2024 for the pump. On February 2025 asked if they submitted the order back in January 2024? they said it was. Now it's August 2025 (20 months since) and waiting. Nhtsa says if they failed to fix in a timely manner to make a report online. Is 20 months long enough? driving with a safety recall. Second making a complaint with the 10 speed auto transmission 2nd to 3rd hard shift and 4th to 3rd hard shift. Putting stress on other components can break mounts, the transmission, axles, ect. Could also launch the car into the car in front of you, in heavy (slow bumper to bumper) traffic. Wasted my own money and time draining and filling 5 quarts of Honda 2. 0 transmission fluid. (also replaced the trans filter behind the warmer housing) did not fix the issue. Contacted american Honda and they said it's out of warranty and I need to pay for diagnostic and repairs. (I just bought the car in 2023 at 45k miles. Previous owner must of felt it and should of did something while under warranty. ) Honda know this issue from the beginning and hiding the issue to save money. Check the Accord forums online. It's most of us if not all the 18-20 10 speed models. Vehicle is 2018 Accord 2. 0 10 speed 50k miles. Plus the normal phantom braking and lane departure which will automatically steer you off the road, so you have to fight the steering wheel.

Car would shake in the morning would wait till warmed. Immediately brought to Honda where I had a diagnostic completed approx. 9/3. Reports says head gasket. Car well taking care (maintenance) no reason for blown head gasket. Got a second opinion they had the car for a week. No warning lights, and did another diagnostic and nothing showed at the time. Brought the car home. After a few months waiting for warning sign or other signs it took a couple of few months for the engine light to come on and it slowed down and came to a stop. Had car towed to Honda. Called Honda corporate. After finding out they weren't going to cover the cost of $5000+ knowing this has absolutely nothing to do with the customer being negligent with car. I can not afford that kind of money and had it towed to the same mechanic where we are still waiting for the parts to come in from Honda factory and it's been in his possession for 2 weeks. I had to get a rental which Honda would not cover. There is no way that a car that is 5years old under 80,000 miles should have engine work unless it was not cared for properly. I have proof of continuous maintenance. I should not be held reliable for malfunction parts on the car and other Hondas are having the same issues. It was very dangerous and scary having the car shake when driving and not being abled to accelerate on the gas with no warning of any. I had it towed 2x to 3x waiting and praying that Honda will be responsible.

Automatic emergency braking occurred three different times for no apparent reason. The car slowed down on a major road. I never reported it. No. A large orange message "brake" on the dashboard while it occurred.

Around 7:45am full day light, clear weather, I was driving on a surface street with multiple lanes (3) going in a single direction with a center divide between the vehicles going in the opposite direction. I was traveling around 40 miles an hour there were no vehicles in front of me or beside me and no objects in the road. I had my foot on the accelerator and suddenly without any warning the automatic emergency braking system engaged throwing me and contents in my vehicle forward. It felt like hard braking and clearly a malfunction of the vehicles adas. I felt very fortunate that no one was traveling behind me as the braking was so sudden that it could have lead to a rear-end collision. This is the second time this has occurred since owning the vehicle. The first time was 2021 and I was driving on the hwy at 75 miles an hour and the vehicles automatic emergency braking system engaged. I through it was a fluke so I never reported the incident.

When going under an overpass, my cars automatic braking system senses the shadow from the bridge as something in font of me and my car slams on brakes. No incidents have occurred at this time. It has happened at least 10 times and each time no one has been behind me. If there were someone behind me they would rear end me. I explained my concern to flow Honda in burlington and they suggested turning the feature off each time I start my car since there was no recall.

A car merged into my lane, the car braking light went on and a beeping noise sounded. After the car in front of us turned and nothing was in front of us, our Honda broke abruptly and if it wasn’t for the seatbelt I think I would’ve hit the windshield. My daughter is afraid to get in the car because of this incident.

Random braking. Freeways or side streets. Fast or slow. Usually it seems to happen in school zones. Nobody in front of me or to the side. Problem comes with braking by itself, is that I almost get rear-ended. People are always trying to push me faster than speed limit. I surprised it hasn't happened yet. Been doing it since new. Had at dealer to lookat it few times. It just got frustrating. They can't replicate. That's the problem. It's random. Almost got rear-ended today. That is why I'm writing this today 10/16/2023. Been needing to do it for awhile.

Automobile automatically, abruptly and forcefully applied the brake during normal driving. No apparent obstacle appeared that should have caused this behavior. However, the time this occurred was late in the day and long shadows of trees and shrubs were crossing the road at the time. The vehicle is available for inspection upon request. Driver was driving 40 mph on a suburban road with other drivers behind and to the side of the vehicle. Safety was put at risk as other drivers had to react abruptly to avoid a collision with and in reaction to the subject vehicle's stopping without apparent reason. Problem has occurred more than one time, including today being the most recent incident. Vehicle has not been inspected by manufacturer, police, insurance representatives or others. Only message displayed with brake in large flashing letters (black and yellow characters/background) while the car was braking automatically. Braking lasted approximately 1 to 1. 5 seconds and brakes were released before vehicle came to a full stop.

"supplemental restraint system failure" warning is intermittently illuminated in the dashboard. It comes on when the car is in drive, moving down the road, and when the car is in park. Warning goes on and off randomly. Dealership couldn't tell me what the problem was. Just suggested I replace the (very expensive) module to see if that works. On 4 different occasions the emergency brake system has gone off and the car has slammed on it's breaks while driving 50-55mph down the road with no object/ vehicle in front of it. Thankfully no one has been behind me when this has happened because I would definitely have been rear-ended if they were.

On about 7-10 occasions since purchasing car new, the automatic braking system will engage brakes for no reason. These have all been in cuise control mode and with no cars in front of me. It is a very hard braking and a many of the times on interstates going 70 mph. Have no idea why it does this, but definitely feel it is unsafe and makes me wary of this situation happening in the future (as I'm sure it will).

When I am driving, the car turns off in the middle of the road and this warning message appears: collision mitigation braking system problem see your dealer. I took it to the dealer. They changed the battery, but the problem still occurs. This is dangerous because the car cut off in the middle of the road where you can get rear ended.

I was traveling on interstate highway 91 eb transitioning to connect the interstate highway 605 nb. The emergency brake abruptly engaged and jerked/slammed my upper body forward and then backward. There was no vehicle in my path that warranted the auto braking system engagement.

I was driving my vehicle on an open highway. There were no road hazards or other vehicles in front of me when my car slammed on the brakes. The brakes caution light flashed and beeped on my dashboard and the car slammed on the brakes. If I had another vehicles behind me I would have been rear ended. This is the 3rd time my vehicle has done this since I purchased it.

The contact owns a 2018 Honda Accord. The contact stated that while driving approximately 35 mph, the brakes locked up and the vehicle came to a sudden stop. The driver and passenger were jolted towards the windshield. The brake warning light was illuminated. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 7,000.

1. The collision mitigation breaking system is braking for no reason, at random times while driving 2. My safety and the safety of others is put at risk because when driving on an open road, cars behind me may not have time to break and this could result in an accident. Not to mention, there's nothing in front of my vehicle, so normal things on the road don't cause drivers to assume a car with suddenly brake 3. Yes, the issues been confirmed but I'm expected to pay for it when this has been recalled on several other models 4. This has been happening for the last several months. I put a note in my car to turn off the sensor but as of today, my vehicle will not let me turn off the sensor anymore.

Car randomly brakes while driving.

On April 7 at 1230p I was driving about 45 mph on lindbergh blvd in creve coeur. As I was moving into a construction area there was a sign to lower speed to 35. I lowered my speed with my brakes and at the same time traveled over a metal plate on the road. After I let up on the brakes there was an immediate very jarring breakage done without my foot on brake as I went over the plating. The abrupt braking was so severe that all of the belongs on both front passenger and back seats all fell to the floor. There is no doubt in my mind that if there was a car behind me they would ran right into me. After going over the plating the braking system was released and my regular driving ability resumed. I would be afraid to try to reproduce this problem. Since owning the car I have had about 5 less severe problems with this automatic braking system on this same road with the system sensing something that was not there (I thought it was a policeman's radar) with a very very short and less severe automatic braking. I did not not notice any warning lamps, messages or other symptoms of the problem .

I have had a few instances where I was driving and the brake warning light started flashing and the car broke. This latest incident was today and it was extremely dangerous and scary. I was driving and no one was driving in front of me the car warning brake light flashed and the car came to a complete stop, the car behind me had to swerve to avoid hitting me from behind and I wasn’t even able to press on the gas to move until after a few seconds!!.

While I was driving down highway 101 near mountain view near the shoreline off-ramp, the vehicle's cbms activated at highway speed even though there was no car in front of me. The weather was cloudy but visibility was good. The vehicle displayed "brake" together with a warning sound, and the car suddenly decelerated. Luckily there was no car behind me, since the sudden braking could have easily caused an accident. I can confirm that this is repeatable -- on three occasions, the cbms engaged at the exact same place where there was some surface imperfection in the road (due to recent asphalt patching). I had to step on the accelerator immediately to ensure the car behind me didn't rear end my car. I've read reports about the Honda Accord 2018 having this potential defect and wanted to make sure this report is filed, especially because it is repeatable. For now I've had to disable the vehicle cbms to prevent an accident from occurring.

My automatic braking system is activating sporadically with no apparent object in front of me. My car has suddenly come to a complete stop while driving on market street, york PA when there was no traffic in front or to the side of me and luckily no one behind me. The "brake" alert flashed and the car literally screeched to a stop. This happened again when I was in stewartstown, PA and was starting to go over railroad tracks, it suddenly stopped. Again, no one was in front of me or behind me. I routinely drive I-83 from york to harrisburg 3 days a week to go to work. If this would happen to me on I-83, this would cause a serious accident. I contacted apple Honda and was told the system is just really "touchy" and there is no fix. The person I spoke with said a leaf blowing across the road could trigger the system. I have to deactivate the anti-collision feature whenever I drive. This is a serious issue that has been around for several years According to researching the issue and Honda refuses to fix this.

Automatic braking has randomly come on, causing harm or injury to those traveling in the vehicle. The few times that is has engaged has never been due to a close vehicle or object in front of the car.

Braking system caused my daughter to have an accident. My 2018 Honda Accord sport has been braking on its own for quite some time now. I attempted to turn off all safety features but somehow missed the braking system feature. The car will brake on its own with nothing in front of it. It will give beeping noises and flash “brake” on the dashboard. On 10/12/2022 my daughter was on the interstate, the roads were wet with heavy traffic. She called me saying that she had an accident. The officer stated that speeding played a part in causing the accident. My daughter said the car just started beeping and she noticed she was going to slow in traffic so she preceded to get in the right lane. Upon doing so she said that my car just started spinning and she took her foot off the gas and never applied pressure to the brakes. She ended up on the other side of the road hitting a guard rail. I feel like the braking system played a huge part in this accident.

While driving the vehicle loses power in traffic or on highway. The brakes won’t stop and the gas won’t accelerate. It’s like the car dies the light all come on reading warnings break mitigation system, break abs loss of engine power. I have had this looked at by the dealership and they just replaced the battery and the problem keeps occurring. I’m scared as I travel with small children. I hope this matter is looked into because it cause myself and other having the same issue a serious accident.

While I was driving at 45mph and there was no vehicle/object in the object, automatic emergency braking was applied and released. Luckily there wasn't any vehicle right behind otherwise I could have been rear ended. This whole experience was quite shocking and it took me a while to recover from it.

I was driving on the highway at about 45 mph when the car suddenly came to a stop without my touching the brake ( it wasn't as if the brakes were slammed the stop was relatively smooth but quick}. When I tried to use the accelerator to speed up, there was no response. I was unable to pull off the highway. I'm not sure what I did next, but I think I touched the brake. Within about 30 seconds I was able to resume using the accelerator. I don't think this was operator error. I drive this car infrequently, and it operates differently from the Tesla that I usually drive. But I don't think I was the cause of this.

Hi my car the date Monday 12 September 2022. The car don't start and on the display is warning. Brake system problem. Parking brake not available. Brake performance may be reduced. The rear right caliper side is all broken complete internally. This is a real safety problem.

I have noticed a few times, at least 3 I can recall in the past year I’ve had the vehicle. The most recent being, I had just merged into a left lane. Traffic was light as it was around 8am going the opposite direction of heavy traffic and I was taking my child to school, and my car suddenly jerked like a hard brake motion. I could also hear what sounded like the abs trying to stop the car, kind of like thump but followed by a deep grinding sound like when you suddenly slam on the brakes. I looked to my side and there was no cars near me just the vehicle that was a few cars ahead of me and no one behind. The car was drove fine after that but it worries me that it could do it at the wrong time.

On July 31st, 2022 at approximately 1135am central time on I-90 westbound near dekorra, WI when passing a tow truck in the middle lane as I was in the right most lane the automatic emergency brake system sounded visual and audio alerts urging me to a *brake now*. Adaptive cruise control was engaged at approximately 73mph.
