2024 Honda CR-V FORWARD COLLISION AVOIDANCE

Auto braking system randomly goes off. When it does go off there is nothing the driver can do causing danger to driver and others on the road

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.

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.

While using Adaptive Cruise Control at 47mph on a local highway, Automatic Emergency Braking activated almost stopping the vehicle with vehicles fairly close behind it nearly causing an accident.  There were no vehicles beside our car and no vehicles or objects on the road in front that could trigger the braking.  This has also happened several times at lower speeds on less crowded roads.  After the last occurrence, I took the vehicle to the Prescott Honda Dealership where they were unable to duplicate the problem.  They documented the problem but told me that Honda would not replace the sensors under warranty unless the Honda Technician was able to duplicate the problem while driving it.  If this happened on a busy Interstate Highway like I-40 or I-17 at 75mph with vehicles or a large truck close behind, it could cause a serious accident.

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.

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.

On Sunday [XXX] and also other times before this, the vehicle will do a fantom breaking. It will slow down, brake, when no other vehicles are near by. On [XXX], the vehicle braked hard while I was in cruise control and traveling on [XXX] near Baldwin, WI. At this time the adaptive cruise control, forward collision warning and brake system warning lights came on. the vehicle was okay to drive the remainder of the way home. I took the vehicle to the Honda dealer on Wednesday February 26th. They reported that they found Code P2583-49 millimeter wave radar fail. They said that they cleared snow debris off front bumper but there was no snow debris on bumper. It was 40 some degrees. I wanted to make you aware of this system problem because the unexpected braking is very hard and could cause an accident if a driver over responds.

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.

The contact owns a 2024 Honda CR-V. The contact stated that his girlfriend was driving at 65 MPH when the collision avoidance activated and stopped 40 feet before reaching the vehicle in front. The driver noticed a vehicle driving at approximately 50 MPH from the rear and attempted to avoid a collision however the vehicle failed to drive and remained at a halt. As a result, the vehicle was involved in a rear-end collision. No warning lights were illuminated. The vehicle was towed to an independent mechanic per the insurance company where it remained and the hatch, body line, hybrid batter, and bumper along with other unknown components needed to be replaced. The vehicle was not repaired and was pending repairs. No air bags deployed. The contact who was a front passenger sustained a herniated disc, the neck, shoulder, spine, and entire back, and urinary tract injuries. The contact's girlfriend who was the driver sustained whiplash, back, neck, concussion, left arm, shoulder, spine, and right ankle injuries. Medical attention was required. A police report was filed. The manufacturer was notified of the failure and 2 claims were opened. The approximate failure mileage was 25,600.

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.

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.

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.

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.

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.

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.

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.

The Adaptive Cruise Control causes the vehicle to brake when close to another vehicle when in different lanes of traffic on highway/freeway turns. The adaptive cruise does not appear to communicate with the lane departure system and thus doesn't realize other vehicles are in different lanes. This has occurred 3 times in the 2 weeks I have owned the vehicle. The Adaptive Cruise Control does not understand the vehicles are in different lanes causing it to brake for no reason when turning as the radar only points forward. Adaptive Cruise does NOT warn the driver that it is detecting a problem and/or reacting to a detection, it brakes very hard due to thinking the two vehicles are about to collide despite being in different lanes and thus a collision will not happen. Vehicle has not been inspected by dealership, manufacturer, police, or insurance.
