This has been reported one time before but the situation has gotten worse when driving at approximately 60ish miles per hour but it starts doing it about between 50 and 70 mph when driving and the car is using the regular engine not the EV section. You will randomly lose the ability to accelerate and you have to remove your foot from the gas let the engine slow and then re-accelerate now for the second time as I'm driving I lose the ability to accelerate at all and no matter what I do the car will slow almost every warning light on the dash comes on and there are 11 different warnings I've uploaded photos of a few I have a video though also and you lose complete power and ability to drive warning lights such as power steering problem emissions problem powertrain problem all of those are part of what turns on if you try to move the vehicle it will not move unless it is an EV mode and even then it only works for several feet but you can't get over a few miles per hour if you are on the highway like I was going 65 mph and there's traffic is extremely dangerous the only reason I was not hit was because I turn my emergency lights on and was able to maneuver my vehicle to the shoulder safely had I been in a more busy section of the road or had I been in an area where I could not get off the road I would have been hit by another vehicle. Honda has stated they can't find anything wrong with the vehicle but a quick Google search shows that this is a common issue and I have a video of the dash with all the warning lights should anyone need it as well as photos.

Incident

While driving the automatic brake system randomly starts flashing brake across the instrument panel and begins to brake the car. This does this while there are no other vehicles or any type of obstacles near the vehicle. It also, does it at random caution lights for the fire department on a 4 lane divided highway. There is no way to stop it from doing so. This happens frequently and leaves the driver with no control over the braking system.

I was driving northbound in on I15 in Salt Lake City when a Home Depot Bucket blew into my lane. I slowed down to change lanes when the Collision Mitigation Braking System (CMBS) deployed without warning, bringing my car to an almost stop causing a semi tractor trailer to hit me from behind.

Incident

Oct 21, 2025

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle’s collision avoidance automatic braking system is malfunctioning. It engages unexpectedly while the vehicle is moving with normal traffic flow. The system is still installed and fully available for inspection upon request. How was your safety or the safety of others put at risk? The automatic braking system activates suddenly and without cause while I am driving at typical speeds (approximately 40–60 mph) with the flow of traffic. This unexpected braking creates a serious risk of rear-end collisions, both endangering me and putting other drivers at risk of crashing into my vehicle from behind. Has the problem been reproduced or confirmed by a dealer or independent service center? I have reported the issue to the dealer, but they have been unable to replicate the problem during their inspections. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? No, the vehicle and its braking system have not yet been inspected by the manufacturer, law enforcement, insurance representatives, or any other third parties. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights, messages, or other indicators were present before the issue occurred. I purchased the vehicle last month, and the problem with the collision avoidance braking system has been present consistently since then.

Car says “brake system problem, brake performance may be reduced. See your dealer” and then another one saying “brake hold system problem. Apply brake when stoped. See your dealer” and another one that says “Electric parking brake system problem. Parking brake not available. See your dealer.” And I know quite a few people with accords that are having this issue as well!

Brake noise from rear whenever backing out. After several visits to Space Coast Honda was assured it is nothing. Because it is getting worse and braking involved, I am concerned. This began with purchase of vehicle and continues today. Wrote letter to American Honda Motor Co in July of 2023 but never received a response.

I have only had this car 4 months, if that long. I have put very few miles on it. Driving home from work, at most 35 mph, there was a loud thud from what seemed the floorboard followed by a sharp slam of the brakes that i could not control. Many of the instrument warning lights came on. some flashed, some stayed on. I was able to pull onto the shoulder of the road to call for help. However, upon trying to put the car into gear again, it would not move. This is very very disappointing as it was purchased at not only an expensive price, but bought with a promise of your Honda dealership. It is noteworthy that i had just returned home from a trip a day or two prior to this happening. Had this happened unexpectantly in six lanes of traffic, it would have certainly caused an accident or worse. After doing some research, I see there were many defects specific to the make and model of this car. I was never informed of any of them. Please see CVT control information published for reference. I have spoken with the dealership multiple times and I have been unable to come to any resolution concerning this new vehicle, that is unable to be driven. Scary and Dangerous!

I was driving home in the rain and felt the car automatically braking when there was no car or object in front of me. The car was also slow to accelerate because the brakes were automatically applied. 5 miles later numerous warnings appeared on the dash and the following error messages came through my Hondalink app: Electric Parking Brake Problem, CMBS Problem, Adaptive Cruise Control Problem, and RDM Problem. Several times during this drive home the brakes automatically applied without any intervention from me or roadway object. I almost got rear-ended once when a car behind me had to slam on its brake when my car automatically braked without me doing anything. This is a very dangerous condition that should be looked further into as multiple drivers have reported brakes being applied without driver intervention or an apparent road hazard. How many complaints will it take before a recall is issued so other Honda drivers do not need to be put at risk?

On four occasions I was required to slam in my brakes to avoid hitting a car in front of me on major highways in Virginia. When engaging the brakes the antilock brakes did not engage, the idle system (such as when you come to a red light and brake cuts the engine idle) kicked in and I lost the ability to steer. I had to release the brake for the idle to re-engage then hit the brake again. I finally was able to stop but left approximately 6 feet of skid marks on the highway. I have reported this to my dealership for them to say brakes are performing as designed and they did nothing. My car has been at the dealership for 2 weeks and I’m driving a loaner. Rear brakes have high pitch noise when backing up but dealership said they can’t recreate it therefore will do nothing. I had one service manager say he did recreate the noise and was fighting to get rear brakes replaced but then called back to say “I misspoke and Honda did not hear the noise so not replacing rear brakes. All phone messages are recorded on my cell phone. I have filed a complaint with Honda Corporate and also called local law enforcement to see where liability falls if my brakes fail again and I hit someone (faulty equipment charge). Was informed by police to have all service orders in the car to confirm I did all I could to get my brakes fixed. So three trips to dealership, almost 4 accidents, and car has approximately 24k miles on it. No idea if this is a sensor problem or several interactions between all the different systems but this is a major problem. Your engine shouldn’t cut off and cause steering problems when you brake the car and are still moving forward. No one can give me options with this car other then trade it in and get something else. This is not acceptable. Someone could be seriously injured. I don’t want to be that driver.

the steering wheel shakes extremely when using the brake. especially at 60 to 65 miles on curves it's awful. (2) throttle is slow to react as if losing power. Apart from small climbs when I stop and release the brake the drive tends to go backwards as if it were a car with a manual transmission. Honda Dealer from downy. Can’t find the problem.

When turning left or right from/into a parking spot a rubbing sound (similar to two pieces of rubber rubbing against each other) can be heard in the cabin and sometimes from the left wheel well area and slightly felt in the steering wheel. No safety issues are currently present at this time but vehicle should not be having this issue in less than a year of ownership. Vehicle has been taken into Hoen Honda in Carlsbad, Ca 5/28/22 12:47pm. Two technicians inspected the vehicle and were unable to replicate/notice the problem but customer is able to replicate it but was not possible to identify source. Noise was not profound so dealer recommended to wait until noise becomes worse to re-diagnose. Customer has a personal mechanic that recommended they take the vehicle to a dealer due to car having 8k miles and still falling under warranty but did not attempt to diagnose or repair vehicle. No warning lamps or component failure has happened yet but symptoms first appeared around January 2022. When reversing the vehicle and slightly applying the brake a loud groaning sound can be heard from the rear brakes. Due to the brakes being a safety component any noise associated with brakes becomes a safety concern. Vehicle was inspected at the same time 5/28/2022 12:47pm as the steering noise at Hoen Honda in Carlsbad, Ca. Brake noise was not able to be replicated by technicians at the time but was recommended to lubricate rear brakes. If issue persisted customer was advised to return to the dealer for further diagnosis. Brake noise was able to be confirmed by customer's mechanic. Customer was advised to take it in to dealer for diagnosis due to vehicle having 8k miles and car still being under warranty. No warning lamps or other symptom prior to the problem. The problem first appeared in January 2022.

My car is not even 1 year old and I have been having problems with my rear brakes. They squeak or grind when I am in reverse and with my foot on the brake pedal to back out of a parking spot or drive way etc. I have taken it to the dealership, Right Honda-Scottsdale Az, 3 different times. They said they could not reproduce the sound. The service guy on my first visit said that if it continues they should replace rear brake pads and deglaze the rotars.Never happened. Left it there overnight, at Honda Corps direction, again the same thing. I spoke with Patrick at Honda and I sent him an email with a video of the sound from outside the car as well as inside. He got back to me last week and basically said there is nothing they can do. I have taken it to a car repair place that I have been going to for 30 years and showed them the video and they said that in there opinion the pads should be changed and rotors deglazed. I explained that to Patrick from Honda and he said they would not do that since they are not sure it would work. Asked him what they would do and he attributed it to either weather etc. Told him I have had at least 10 accords and never had this problem. The car is less than a year old with just 10000 miles on it, less when I first took it there. Really not sure what the issue is but it is very concerning since it concerns my brakes.I have tried to upload the video but I cannot. You can email me and I can attach it.
