What 653 owners told NHTSA about the 2019 Honda Accord Plug In Hybrid

When I am driving on the highway, sometimes my car just brakes. This has happened 7 times! I am lucky I am not dead, or I have not killed anyone yet. It will go from 60 mph down to 20 mph all of a sudden. I am scared to drive my own car.

I was driving about 40 mph when my car slammed on the brakes. There was no vehicle in front of me. There was no warning message. The word "emergency " appeared on the dashboard. This could have been a serious accident had I been on the beltway. This problem needs to be addressed immediately.

My accord seems to trigger automatic brakes for no reason. I have noticed it happening primarily on freeways and expressways (while traveling at high speed)which is extremely dangerous. There has been only a single instance of this behavior while driving on a 35 MPH posted speed corridor. My latest experience was on 6/29/24 around 10:30 am. Contacted the dealership with the issue. They said they will call back, but haven't heard from them yet.

I was driving about 35 mph with nothing in front of me and suddenly, the “brake” warning came on and the automatic brake engaged. There was a car behind me, but thankfully far enough behind that a rear end collision did not occur. I’m very concerned. I think the system is called CMBS (collision mitigation braking system). I would just as soon not have to have it!

Honda is delaying the safety recall and because of that I am loosing money ! Honda is costing my business to loose money ! How this can be handled ? This car also ended up in the crash and now my car value is not the same and I am in negative equity

Emergency front collision braking system activates out of nowhere, causing the car to suddenly brake with no warning, although there is nothing in front of the vehicle. Now all the mitigation system lights are on, and the braking system is no longer working. I took it to Honda to repair it twice within the year, and now it happened again, almost causing an accident.

NHTSA ODI 11592720

The car detects something in the road even though there is nothing in front of the car. When it detects, it applies emergency brakes. This has almost caused me to be rear ended a couple of times

This car brakes on its own . I reported it to Honda since I have had it have been dealing with the issue it brakes on its own I filled out a form with you guys after reading about “Ghost Braking” so I am not alone this car is dangerous it has been serviced multiple times Honda Corp is aware requested a buy back. Wondering where you guys are in your investigation I have pictures the sensors are all out of whack mitigation control warnings etc but the car literally brakes on its own highway and street Honda states they cannot disable the features. I need help. Please update me Occurred again today

This is the second time it has happened with my car that the automatic emergency braking system got applied and there was no one in the front. The braking system beeped as if it was about to collide and then it braked. Today a car behind me was almost rear ended me because of this sudden braking.

I got an oil change done and everything was fine brakes were good , battery , engine , everything . Then dashboard lights came on the engine light saying to take to dealer the. The ADAS system sensors popped up when I’m driving they will automatically slam on breaks if I’m not even close , now it’s having a hard time starting up

NHTSA ODI 11588270

My car suddenly triggered automatic emergency brake even when there is no apparent reason or no blockage ahead of the car. This might cause rear side collision.

NHTSA ODI 11587548

Vehicle ACC, Lane Departure system and collision mitigation braking system all turn off and there is no recall. This has caused unwanted braking at times as well. Overall, this system is completely non-functional in my vehicle and I am seeing this issue with other people all over the internet. There has been a new battery installed, multiple attempts finding a solution and nothing on the scanner comes up. WHY HAS THIS NOT BEEN SET AS A RECALL? IT IS EXTREMELY DANGEROUS!

The car brakes hard while your driving and there is nothing infront of you without warning and hurts your stomach with the seatbelt. Also when passing over a train track the car beside me went over it and the rail got detected and made the car stop hard.I was with my girlfriend and she is pregnant and the seatbelt got stuck for a moment and since it broke over the train tracks and the force made us fly forward and the seatbelts hurt our stomach but good thing there was no accident or anyone behind me

NHTSA ODI 11584201

Vehicle has applied brakes automatically for no apparent reason at least 10 times in the 4 years we have owned the vehicle. 2 of those incidents was entering a freeway under acceleration from a on ramp putting us in a dangerous situation. It did not completely stop us before it released the braking system. It has also happened when exiting the freeway onto a off ramp numerous times automatically applying the brakes when nothing is in front of us or beside us. Last time it happened was last week while driving down a divided highway with no vehicle beside me or anywhere close in front of me a car was behind me and had to slow down. My car automatically applied the brakes and slowed me down and would not accelerate for about 10 seconds then they released and I was able to accelerate back to normal speed. To not it does not slam the brakes on and lock them up but it does start to slow you down quickly before allowing you to accelerate again. In the wrong situation this could cause a accident or a string of accidents.

The vehicle will have the "COLLSION MITIGATION BRAKING SYSTEM PROBLEM. SEE YOUR DEALER" warning come on periodically. When the warning has been on, the vehicle has occasionally randomly braked hard. The warning typically goes off after the car is turned off.

NHTSA ODI 11572770

Automatic braking occurs at any time for no reason. This is extremely dangerous. I've almost been hit from behind a dozen times when my car suddenly puts on the brakes for no reason. I submitted this information to you several years ago and never heard a thing back. This system was apparently designed for people who drive impaired/distracted who shouldn't be on the road to begin with. I drive attentively and if I need to apply the brakes I do so. When I'm being tailgated it freaks me out because I know it's an accident waiting to happen if my car slams on the brakes. I can not turn this function off or disable it. (the date below is today as this field is required. It's been happening on average once every 100 miles.)

All warning lights come on and engine lags. Lights come on every time and lags about every 10th time driven.

On Thursday November 16th at around 8:00 am I was driving down La Cienega Blvd going around 30-40 mph. I was about to pass a green light when my 2019 Honda accord sport started showing the brake signal on my dash. My car suddenly brakes and comes to a complete stop by itself in the middle of the road. There were no cars in front or on either side of me, no potholes or anything of that matter that would’ve caused this to happen. I am now suffering with severe neck and shoulder pain from this unexpected incident. My 1 year was also in the car with me. My car is now being inspected at the Honda dealership where it was purchased.

I was highway driving when suddenly a brake light flashed on and off and car came to an immediate stop (then go). There was no use of the brake pedal, nothing ahead of me - and fortunately no one behind be which could have resulted in a serious crash, Safety was a major risk!! Husband checked fluid, car is now "awaiting" inspection at a reputable diagnostic service location. Read an article about these similar defects/complaints, but the Honda dealership claims there have been no like incidents, complaints or concerns. I read otherwise that indicated such events were under investigation (CNN Wire Feb 27,2002). When I called another dealership, they explained that there were not enough complaints to warrant a (safety recall). I beg to disagree!! Today's date is 11/04/2023. Thank you.

Since may or June of 2023 my car has automatically breaked at random times without coming close to anything. It has happened approximately 5 times, 3 times on the freeway when I was going anywhere from 40/70 miles an hour and twice on side streets going less then 20 miles an hour. It has caused me to think I was getting rear ended due to the brakes slamming for no reason.

My car will be driving down the road and all my lights will come on and go to fix the problem and they all come back on . I’ve had the car for two years and been in the shop majority of the time . First the front senor was bumped out so none of my safety equipment on the car did not work , all my lights where lit up and check engine was blinking and went to take to Honda dealership and they said they tightened the bolts and car is running good and I picked it up and 15 miles later all my lights came on blinking , this has been ongoing and I know online the years 2018-2021 have has similar problems. I have a warranty but I want to get this checked out for others as well

We were driving on I 75 southbound just north of Knoxville. We were in high speed lane going 60 mph (adaptive cruise control and front collision mitigation systems were on). We were on cruise, and had been for many miles. Our cars adaptive system had slowed us to 60 mph due to traffic, and again this had been for several miles. The cars braking system suddenly brought the car to a stop. I swerved to left to get in median and floored the gas peddle to get out of the way of traffic behind me but nothing worked. The car came to a complete stop in seconds. Again in high traffic in the fast lane of interstate. It was a clear, beautiful day. Luckily the 3 vehicles behind me were able to swerve and brake in order not to hit us. If it had been a semi behind us…. We would not have had a chance.
