*****asterisks are used in case your system does not support paragraph separation. *****while traveling on the highway with lkas on and lane markers registered (per the readout on the instrument panel), the vehicle will attempt to steer toward the very edge of the lane near a large vehicle (pickup truck, semi, etc).

I purchased the car July 3rd, 2018. Driving on a trip at around 900 miles and had the adaptive cruise control engaged. The car made a beeping sound and the cruise control powered off. A message came up stating collision mitigation breaking system needed to be serviced. The cruise would not come back on. When I arrived at the destination I turned the car off, and upon turning it back on the warning was gone. I drove home with no problem.

I was driving straight down a residential street, accelerating and the braking system automatically stopped the vehicle and the transmission automatically went into neutral. The car motor was still running but the car was inoperable. The gearshift indicated the car to be in drive but would not accelerate. I moved through the automatic gear shift selections but nothing happened. The dash brake failure contact dealer light appeared, then transmission failure contact dealer warning light appeared. I called the dealership and was instructed to turn the car off and restart, which I did. The car restarted, there were no warning lights and I was able to drive the one block to home. The dealer told me to drive it to the dealership which I did not do as I did not feel it was safe. It was fortunate I was not on a freeway or in traffic as I most likely would have been rear ended because it came to a complete stop unexpectedly; for no apparent reason and no notice like brake stop lights to warn other drivers the car was stopping. I had the car towed to the dealership. I was informed that the transmission needed to be replaced.

Just like others have said, I'm also having an issue with the sensitivity of my brake pedal. The brake feels like there are steps to it instead of a smooth linear pedal. I have never driven a car with a brake pedal like this. From the first stop leaving the dealership after buying my 2018 Honda Accord 1.5, I knew something was wrong with the brakes. The pedal feels binary like the brakes are either on or off and not smooth and linear. It's either full brake or no brake and no in between. There are steps to the brake pedal and it makes it impossible to brake smoothly. This has caused back pain and if the Accord I test drove felt that way, I would have never bought one. I drove a friend's 18 Accord and it didn't feel that way at all. It's been to the dealer twice now and I told them the brake booster is likely the issue and they've just pushed back with "it feels fine" or "it needs to break in". will be opening a complaint with Honda of America.

Collision mitigation braking system problem. See your dealer. Warning light. Vehicle in motion in a round about turning right. Light stayed until car was turned off. Then light was off.

At 670 miles, I was driving slowly around a corner when I heard a long beep followed by a "collision mitigation braking system problem. See your dealer" message. The adaptive cruise control also stopped working. I restarted the car and the error went away. About a week later at 813 miles, I was driving in a straight road at 55 mph with the adaptive cruise control engaged when I heard a long beep, the adaptive cruise control disengaged, and I received the same error message as before. Restarting the vehicle clears the error and allows the adaptive cruise control to work again until the next time it occurs. Both times this has happened were on warm, sunny, clear days with dry roads and no obstructions in front of the radar or camera units. Yesterday, the cmbs failed to alert me to a four-wheeler that drove across the street in front of me and it seems less sensitive at detecting other vehicles now - even when there are no error messages or warning indicators present.

On May 25th, I was driving on the interstate when I noticed the brake warning light flashing on the dashboard. I was the only vehicle on the interstate when the brake warning light appeared. On May 29th, I took my car to a local dealership for an inspection. The dealer did not find any errors when they put it on the computer.

May 13th, 2018 driving on the highway doing 50-55 going eastbound on the bay bridge in san francisco -'out of no where' the electric parking brake came on! and I didn't push no buttons! not quite sure of the malfunctioning, but it cost an accident' cause someone hit me from behind! also my airbags didn't deploy, but when Honda link assistant called and we was told- 'they sense an accident cause of deployed airbags.' I'm afraid to drive a car that nearly killed us.

Brakes are very touchy and when braking pedal sometimes goes all the way to the floor. Car does not stop smoothly and it seems to have different stages when breaking. It also jerks when when lightly touching break while at a stop light and slowly moving forward.

Brakes do not stop smoothly, there is a dead spot in the brake pedal that takes extra pressure to get the car to stop. Makes the car stop suddenly when trying to brake smoothly. Dealer acknowledged the problem and replaced the master cylinder with no fix and now dealer says they neex to wait for american Honda to allow them to replace the brake booster that have been successful for others on Honda forums

- Naples, FL, USA

Brakes pedal making a loud thumping sound. Dealer will not fix. Since it involves brakes I feel it should be investigated further.

- Whittier, CA, USA

Loud clunk is consistently heard and felt every time the brake pedal is released after being depressed. The noise is more pronounced in cold weather and can be heard above the radio and road noise. The loud clunk sound occurs whether or not the car is moving, or the engine is running or the ignition/accessory power is turned on. The noise can be consistently reproduced and emanates from the firewall area under the dash where the brake pedal linkage attaches to the brake booster.

Three times during the first 1500 miles the collision mitigation braking system has failed, disabling that feature and adaptive cruise control, displaying a large diagnostic on the electronic dashboard and telling me to see my dealer. In all cases I was driving in normal traffic on northern California freeways at cruising speed (twice on 101, once on 80). The first two failures occurred during daytime, the third at night. The weather in all cases was normal (no rain, snow, mud, ...).when I visited the dealer after the first two occurrences (when the car is turned off and then back on the condition clears) the dealer found no diagnostic codes or other problems. Then the problem occurred a third time. The dealer and Honda corporate say they have no idea how to fix it because of the absence of diagnostic codes.

The braking system hesitates and grabs. It is like there are several stages or steps in the brake. It is almost impossible to stop smoothly. As you press the brake pedal in, the car doesn't slow normally until you hit a "step" or "notch" and then it just slows down rapidly and you go forward in your seat. This problem began as the vehicle had around 400 miles on it. The vehicle did not have the problem when I took it off the lot the first time, and other new Accord I have driven do not have the problem.

- Alpine, UT, USA

I am experiencing brake pedal issues. As I put pressure on to slow down, at any speed, it feels like the brake pedal gets "stuck", then it grabs hard and lurches you forward in your seat. As I relieve my foot off and put pressure back on, it does the same thing: The pedal seems to go down in "stages". I cannot brake in a normal, smooth fashion. I have taken the car to the dealer that I bought it from twice in 2 weeks and they have stated both times that none of their staff can duplicate the problem and it has not been resolved as of 3/7/18. The problem was first documented with around 200 miles on the car.

- Fairview Heights, IL, USA

I purchased brand new my 2018 Honda Accord sport Dec 28 2017 I have 1450 miles currently on the car and the brake pressure has been lost. When applying breaks at highway speed its not as noticeable but around town at 45mph when applying the breaks there is dead space then full brake kicks in which makes others think you are brake checking them. When going to the forums and to this website I saw other complaining about the brake booster failures. I went to the dealership. They advised yes the vehicle has a failed brake booster and is on a national back order. I am currently driving my new car with a failed booster waiting on Honda to fix it. I hope this is safe that that my brand new car isn't being damaged waiting for this part.

The contact owns a 2018 Honda Accord. While driving approximately 10 mph, the contact depressed the brake pedal and the brake collision mitigation braking system warning indicator illuminated. The vehicle failed to accelerate. The contact coasted the vehicle into a parking lot, turned off the vehicle, restarted it, and was able to drive normally. However, the failure recurred twice. The vehicle was taken to chapman Honda of tucson (4426 E 22nd St, tucson, AZ 85711), but the failure was unable to be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure and provided case number: 06589496. The approximate failure mileage was 1,000.
