Automatic Emergency Braking problems of the 2024 Honda CR-V

Vehicle repeatedly brakes on its own when there are no vehicles in front to avoid. Very dangerous for vehicles behind and me and passengers. Dealer "cannot" reproduce, denies there is a problem despite 1000s of online complaints and NHTSA safety investigation. Incidents occurred within weeks of purchase in December 2023.

I love my 2024 Honda crv which I purchased in may of 2025. But I need to report this for safety reasons. On September 9, 2025 I was driving south on sare road near davis road in bloomington in at about 30 mph when the collision mitigation braking system (cmbs), activated and stopped the car in an instant. It was a rapid, unintended deceleration. The “brake” message flashed on the dash. This occurred at approximately 7:30 pm, and there was no other traffic around me. No oncoming traffic, no other cars in front of me and thankfully no one following closely behind. There was no collision - however if another car had been behind me they likely would have rear-ended my vehicle. There were no people or animals in the vicinity to cause the cmbs to activate. And I did not inadvertently touch the brake prior to the incident. I was just driving along and suddenly thrown forward and restrained by my seatbelt. I could smell what seemed to be the brakes or tires. I was confused as to why the vehicle stopped. I turned the engine off and checked for traffic, then started the car and continued driving home without further incident. Within a day or two, I stopped in at my dealership ( andy mohr Honda) and reported the incident. Today (9/19/25) I was having a transmission fluid service and mentioned the cmbs issue to the technician and he chanced the settings for cmbs from “far” to “near” and said that should solve the issue and to let them know if it occurs again. My concern is that if it happens again it could result in an accident and cause damage and injury. Especially if I am on the interstate driving at 60 mph.

The vehicle is a 2024 Honda Cr-v ex-l with approximately 13,000 miles, purchased at gillman Honda in houston, TX on may 29, 2024. The issue involves the collision mitigation braking system (cmbs) activating without any obstacle present. The first incident occurred in February 2025 at around 11,000 miles while driving on a feeder road at ~25 mph. The vehicle suddenly braked to a complete stop even though the road was clear. There were cars behind me, and although they stopped in time, it created a serious risk of rear-end collision. Had I been traveling at a higher speed and the car braked completely, this could have caused the vehicle to flip or lose control. The second incident occurred on September 4, 2025 at ~13,000 miles while driving on a busy street at approximately 40 mph. The vehicle suddenly braked very hard for no reason, but did not fully stop — instead, it resumed immediately. It felt as if the car “took a screenshot,” braking sharply then continuing. This was especially dangerous since I was traveling at a higher speed, and vehicles behind me could have easily collided with mine. Both incidents put my safety and the safety of other drivers at risk. The vehicle was brought to gillman Honda on September 16, 2025. The dealer acknowledged the safety concern and kept the car for inspection. On September 19, 2025, the service representative confirmed they had contacted Honda corporate and opened a case because of the seriousness of the issue. The car is still being held at the dealership pending corporate guidance. No warning lights, error messages, or prior alerts appeared before either incident. This appears consistent with a known problem that has been reported by many Honda owners in recent years involving unintended braking by the cmbs system. The defect makes the vehicle unsafe to operate, and at this point we no longer feel safe driving it.

The vehicle has occasionally hard decelerated (braked) for no apparent reason. The term seems to be "phantom braking". This has been going on for a while for my wife and me when either of us is driving. My wife doesn't usually use cruise control and I use it most of the time.

While driving down the road at about 45 mph, my 2024 crv automatically applied the brakes while there was not anything in front of me. I’m [xxx] and honestly it scared me. I’m just wanting to report this because I don’t want anyone to get hurt. I have not taken it to the dealer as this was the first time. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On [xxx] and [xxx], I was driving in the right lane in a construction zone on [xxx] in detroit, mi when my 2024 Cr-v slammed on the breaks while flashing the forward collision “break” warning on my dash. There were no cars at least 500 yards in front of me and, luckily, no one behind me. This happened by itself and no cruise control was engaged at the time. I have had this car since October 2023 and this is the first time this has happened. This was a sunny morning with temps in the low 30s. No rain and no snow. I have yet to be able to reproduce this issue and it’s unlikely that I could, since this happened under normal driving conditions. I have also not had the car inspected yet, but I will when I have the oil changed in a few weeks. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving on a country road and shortly following acceleration after a left turn, the cars forward collision warning went off, but in an unusual way. It will generally beep and flash the brake signal a few times if the forward collision warning activates. This time I heard one loud beep, saw a flash of the brake signal, and then the car slammed on the brakes to a complete stop. Luckily, there was no one and no other cars around me as I was on a small road without much traffic. The car is currently at the dealership being evaluated. I have sent a request to the general manager to investigate this situation further than just a basic code run or recreation of the malfunction. I do not feel comfortable driving this car without a clear diagnoses and repair.

I was driving on an empty two lane road going 35-40 mph. The car braked suddenly and the brake warning light came on but no sound. On the way to the service department at the dealership it happened again, only this time I was going 20 mph and in traffic. There was a car in front of me at least 3 car lengths but was moving. I heard the brakes of the car behind me squeal as he avoided hitting me. No sound from my car, the brake light came on, I also put my foot on the brake thinking maybe the car sensed an encroachment I didn’t notice. But there was none, so I released the brake before coming to a complete stop. The service department inspected the system and could not reproduce or confirm any issues. There was no warning sound, the brake came on at the same time as the light. There was no warning, the light came on at the same time as the brake.

Description of incident: Saturday, [xxx] I was in traffic on I [xxx] near the [xxx] exit in indiana. It was a stop/go, stop/go event as 6 lanes were going down to 1 lane. I was behind a kroger semi-truck. I had my foot on the brake. I thought the people next to me had started to move, but then I noticed that I was getting closer to the truck (while my foot was on the brake). I pushed the brakes down further. I felt normal resistance. Nothing happened. I hit the cancel button of the adaptive cruise multiple times on my steering wheel thinking that perhaps my adaptive cruise started my movement. I kept rolling. Kept hitting the brakes wondering why I didn't stop. No beeps went off like they normally do. I rolled into the truck. My adaptive cruise had been set to 70, and I had used it before the incident. It was still on standby, but not green. My odometer was around 9547. This happened around 9:50am. No beeping sounds started or emergency braking happened. I would approximate my speed of hitting around 3-5 mph. I hit the truck. I had tried to switch to neutral and then to park. I could not move the gear shaft. I was hitting the brake hold. Anything to make me stop. Nothing worked, and I hit the truck. I did not move after hitting the truck, maybe one of the things I attempted to do worked. My foot was still on the brake. I pulled over, turned off the car, and restarted it. I have not applied the adaptive cruise since then. I don't know if it had anything to do with the incident, but I'm afraid to use it. If I had been moving at a faster rate, my safety and others would have been at risk. I took the car to the dealership. They provided me with a Honda multi-point vehicle inspection checklist and stated that they couldn't find anything wrong. There is definitely something wrong. If I manually apply the brakes, the car should stop. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car suddenly slows for no reason. No accidents yet. No police reports. Car suddenly slowing for no reason causes driver confusion and can invite rear end collisions from cars behind. Driving 45 mph with cruise control engaged on a two lane road, car suddenly slows to about 20 mph for no reason. It has happened 3 times randomly at about the same spot in one highway and and twice on other highways. Suddenly slowing while passing large vehicles causes driver confusion, invites rear end collisions, and the inability to safely complete the passing of the large vehicle. When driving 65 to 70 mph with cruise control engaged and passing an 18 wheeler, the car randomly suddenly slows to about the speed or the truck when it is about 10 feet from being nose to nose with the truck. Happens every 5th to 10th passing of an 18 wheeler.

Component: collision mitigation braking system (cmbs) my car has less than 2,000 miles on it. I have experienced the situation described below 3 times now. Traffic on a freeway/highway slowed down quickly, and I stepped on the brake pedal to slow down quickly but still gradually. However, the collision auto-braking system activated and my car suddenly halted to a stop with plenty of room (about 1 and a half cars length) ahead of me. In 2 of those situations, I can see the car behind me quickly react by swerving into the shoulder. Rather than improve safety, this feature created a dangerous situation. In 1 of these situations, I released the brake pedal to move forward slightly (without stepping on the accelerator) and then stepped on the brake down slightly to slow down; the automatic braking system jerked the car to a stop once again.

The contact owns a 2024 Honda Cr-v. The contact stated that while driving at an undisclosed speed, the vehicle experienced phantom braking. The "brake" message was displayed. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure, but no assistance was provided. The failure mileage was approximately 22,000. The VIN was unavailable.

My wife was driving on a 4 lane road after it was wet. The road is flat but bended to the right. Traveling in the middle lanes, the braking system engaged and the brakes fully locked while she was at a driving speed of 25 mph and the car slid across the lanes as she entered the turn. She said it lasted for about 10 seconds before the brakes disengaged.

Braking occurs absolutely randomly. This happened about 6-7 times starting from about 5500 miles, at absolutely different speeds. I slow down to reduce speed, then the system starts warning with a brake signal and after that suddenly stops, to a complete stop, although this is absolutely not necessary, because the front car is very far. I was hit in the bumper once. I have a video of how it did it on the highway. The last time got into the accident with the car, as the hit didn't make any damage to the car, did not report to police, took the car to dealership, but was advised to change the setting, but it did not change anything still the random braking exist.

I was driving down the road, no other vehicles present, no animals in road, road was clear, weather was clear. Going 30 mph and all of a sudden the car automatically slammed on the brakes for no reason what so ever. I am lucky no one was behind me. This is the 3rd time the vehicle did this.

It only happens when I have the car in cruise control mode. The car dramatically slows down for no apparent reason. It has happened 3-4 times in the 3300 miles I have driven the car. It may be related to changing lanes while on cruise control.

I was driving about 25 mph halfway through an intersection with stop lights. The automatic emergency front braking system abruptly engaged and almost brought the car to a stop. I immediately applied the gas pedal to compensate for the braking and was able to keep the car from completely stopping. The car in front of me was about 5 car lengths ahead, moving at a similar pace, and the car behind me was about 4 car lengths away. Luckily, the car behind was able to keep from hitting me.

I own a 2024 Honda hybrid sport Cr-v. The automatic emergency brake will engage only after seatbelts have been engaged. If you have not engaged seatbelts and turn the engine off, the emergency brake will not turn on creating a roll away hazard. This happened to me. I jumped in my car, realized that I left something in the house, turned the vehicle off, and without realizing, left the vehicle in neutral. The vehicle rolled out of our garage and struck another car in the neighborhood resulting in at least six thousand dollars in damages. Fortunately, there were no injuries. This needs to be standard in vehicles that do not utilize ignition keys as I am sure I am not alone in that my protocol has long been to take the key out an ignition anytime I exit a vehicle and this is the first time I have owned a vehicle of this type. Our Honda pilot will automatically place the vehicle in park if someone turns off the ignition, there is no reason for this or, at the very least, an auto emergency brake not to be an option in Cr-v regardless of seatbelt actions. This should be a simple software fix.

2024 crv showing errors concerning brake assist and lane departure. 1647 miles. I had a 2023 sport touring crv. Same messages appeared. At 10,300 miles, when being serviced at the dealership for an oil change, tire rotation, and two service bulletins, I was informed of an “embedded” code saying the main camera needed replacing. Looking online, Honda has an issue. This seems to be happening frequently.

This hybrid model does not display red brake lights during regenerative braking, at any of the settings. I have have had two occurrences where the driver behind me was apparently not aware that my vehicle was slowing somewhat rapidly, and thus nearly drive into the back of my vehicle. One of those drivers mentioned that they did not see any brake lights even though I was slowing down, approaching an intersection. I can see how this might be a safety issue. If Tesla can have this function on their cars software then why cannot Honda? my vehicle also has times when I am travelling on straight city streets with no traffic in front of me, where the automatic emergency braking come on quite firmly for a second or two, without any apparent reason. Again, this presents a possible safety hazard to the vehicles behind me who may be following a little closer than they should, and may possible drive in to the back of my vehicle. Again, I am not aware of any brake lights present on my vehicle when this happens. A big improvement would be in the manner in which the radar sees things and makes false applications of this braking system, as well as having teh vehicle brake lights activate when this system decides to engage.

While driving down the interstate, I had automatic cruise control set at around 70-73 mph, there were few cars on the road and none in front of me. It was dark outside, and one a particular spot, road seemed to have a slight/gradual dip, while going thru this section, vehicle’s emergency braking started flashing and signaling to brake. There was no one in front of me, and it seems as if sensor malfunctioned/received a false positive indication. Luckily, there was no one behind me and I was able to take control of car and speed it back up.

There are a few safety issues I've experienced multiple times while driving this car. To the best of my knowledge, there haven't been any warning lamps or indicators on the dash related to these issues. When driving, the car will activate the emergency braking system, braking incredibly hard at freeways speeds and street driving speeds even though there is nothing near or close to the front of the car. The car has braked so intensely that items fly around the car and that both my son and I have experienced back, neck, and shoulder pain from the unexpected/severe braking. The other safety issue I've experienced is the lane departure/keeping sensors going off on the dash and the car pulls itself out of the lane. It seems like the car thinks I've departed the lane and is trying to pull me back into the lane, but, in reality, I am in the lane and the car is pulling itself into the next lane (sometimes even when another car is next to me or approaching). This is a safety concern since it causes swerving and my car could crash into another car or a lane divider if I didn't react so quickly to overpower the automatic lane departure. It's also a recurring issue to have to fight the car to keep it in the lane and makes for very tense driving. The last issue is an electrical one, I believe, related to the infotainment panel. The power on the infotainment system goes off unexpectedly while driving. It sometimes will not power on during start up. If it turns off while driving, sometimes I have to stop, turn off the car, and restart it to get it working again and other times it reboots itself after a minute or a few. All of these issues have happened countless times, as long as I've had the car. I've had it inspected and during the most recent inspection (sept 2024) they asked me to come in to drive the car so that the issues would be reproduced while the mechanic was sitting in the passenger seat. I was able to reproduce the issues while the mechanic was in the car with me.

When my car is in cruise control it sometimes applies the brake when the car in front of me is taking an off ramp. Even when car is out of my lane the car might aggressively apply the brakes. Sometimes applies the brakes because a car in front of me changes lanes. It only does it if they go to a lane that is right of my car. I do not tailgate so I feel that this is dangerous as I drive on I-95 and the speed limit is 70 mph. This is a 2024 Honda Cr-v hybrid sport. Honda must correct this.
