Honda's collision mitigation system shuts down, disallowing cruise control and all safety features that are included in the collision mitigation system. Dealer cannot find cause. Turning off the car and restarting it resets it, but when it turns off, there is no clear factor as to why it happened. There is a safety risk if you are using cruise control, as it could fail to brake when the car in front of you slows down. It has happened 4 or 5 times in the past 8 months since I bought it brand new.

Rattle/squeak from hud area of driver's side dash after vehicle has been sitting outdoors in the heat. Vehicle is driven in Florida and whenever it is parked outside, especially if left in the sun, there is a loud rattle/squeak from the hud area of the dash for some time after. Passengers in the car constantly ask what the noise is. Dealer has been unable to correct the issue and Honda is aware of the issue. See NHTSA id number 10136423 dated April 2018. Online research indicates this issue also exists in 2019 models as well. Honda needs to find a solution to this issue and implement a fix for something they have known about for over a year. This is our sixth Honda and we are frustrated that something as annoying as this was not discovered and resolved during the vehicle's development and testing. This issue was discovered during our first week of ownership and we have discussed it with the dealer multiple times. They tell us that Honda is aware of the issue and are awaiting a fix from Honda. Until then there is nothing they can do.

7/17/19. 2018 Accord touring 2.0 purchased new in November (has about 11,000 miles now). I was driving 65mph on highway when car made loud clunking noise, began to smoke intensely, and shuddered to a stop and died. I was on bluetooth phone call at the time and the person on the other end heard it and asked what it was. I said I thought the engine was on fire. I was able to pull over just as every possible warning light flashed on dash and profuse smoke poured from sides and under hood. I jumped out and moved away from vehicle, seeing a long stream of liquid from under the car along the road where I had pulled over. Fire rescue came, although the car did not ignite. They and the roadside service man advised me that oil had exploded everywhere, as from a high pressure situation. The car has had one oil change at the dealer, per its maintenance schedule, and otherwise has had nothing done. I did hear a strange noise coming from it the previous evening--loud enough that I checked to see if it had any maintenance warnings, which it did not. It said my oil was at 60% and would need a B1 when it was time. After my car died, it required a tow to the dealership. The dealer said they could not even turn it on and they don't know what is wrong, but they need a specialist to come look at it. I'm concerned about how utterly dangerous the situation was. If it had been later in the day with heavier traffic, my life would have been at even greater risk. It seems really unusual to have such a catastrophic failure for no reason on a new, historically reliable vehicle.

Collision mitigation, lane assist, road departure, and brake system malfunction before vehicle is a year old causing vehicle to leave roadway when using speeds in excess of 50 mph preventing vehicle from stopping, and/or causing steering wheel to "alert" you of lane departure while driving properly also causing vehicle to "steer" into side of 18 wheeler while traveling speeds in excess of 60mph for interstate travel with passengers in tow. Has happened for roughly 7,000 miles. When brought to Honda to be fixed, was told it was not covered under vehicle warranty due to having "clips" broken off of front sensor. Was accused of sensor being hit by something yet no sign of damage. Honda refused to have this fixed and simply "cleared" the alerts causing vehicle to not have use of any safety features but also not show any maintenance codes as well. Honda service manager stated something as simple as a "junebug" can cause this to malfunction and that is why customers carry collision with insurance. States alot about Honda's quality if a simple junebug can cause an entire $30,000 vehicles safety features to malfunction and a service manager not want to comply with safety standards due to some 2$ broken clips that can break by simply driving down a Louisiana roadway. What does this state about these vehicles up North dealing with snow with a sensor that sits underneath the front bumper?

My vehicle was in motion at 35 mph with no traffic ahead of me and one vehicle to the driver-side rear. With no obstructions in the road or traffic ahead of my vehicle for at least a half mile, the emergency braking system activated flashing a "brake" warning light on the dashboard and locked the brakes causing my vehicle to come to a quick and complete stop in live traffic. Attempts to override the system by applying pressure to the accelerator pedal failed to correct the problem. I estimate that it took between two to three seconds before the system disengaged and I was able to accelerate again to operating speed, narrowly avoiding a collision.

The adaptive cruise control will randomly stop working when I approach a car on the interstate. Usually this will happen 1-3 times per 100 mile trip. I need the cruise control and have discovered that if I pull over, turn the car off, then turn it on again the cruise control will function again. Pulling off on the side of an interstate or exit ramp is hazardous. Apparently some people are putting their car in neutral while still driving on interstates, turning the car off, then on again.

While driving on the freeway, the vehicle front collision system stopped the car randomly causing a potential hazard. It is doing it intermittently with nothing in front of the vehicle

I have numerous incidents where the collision mitigation braking system has gone out giving an amber dash warning to see the dealer. When this happens, the cruise control will also not function.

- Florence, NJ, USA

On multiple occasions, while driving on the highway, my 2018 Accord has unexpectedly braked when there was no object/car in front of me. When there is car stopped in front of me, the sensors do not kick in for emergency assisted braking. Something is definitely not right with this car.

I bought a new Accord in September 2018, there was noise in the car, the engine also had abnormal sounds, terrible dealers, terrible service, terrible american Honda! they can't solve the problem, just shirk each other's responsibility! recently I found that the lane keep system is not working properly.I have already gone to the Honda service station 10 times for these questions! but they just told me that these are not problems. It's just unacceptable.

While driving I received error code advising that the collision mitigation system had failed and I should see a dealership for service. After stopping and turning off the vehicle the error message went away and system was showing to be functioning. 2 weeks later while driving at slow speed in my neighborhood I got the same error message. Again, stopped and started the vehicle and message goes away.

In colder weather, the vehicle makes a drone like humming noise, similar to running a wet finger around a wine glass except louder. If I open the window it stops, it also stops below 5 mph. It is very distracting, I almost went off the road trying to figure out where the noise is coming from. The dealer is telling me it's the speakers, but why would it stop when the window is open. I believe it's the active noise cancellation anc - once the vehicle warms up 15 - 20 minutes the noise stops. I feel this is a known safety hazard that Honda is trying to figure out. One dealership told me the "engineers are working on it, but no fix at this time". this is a brand new vehicle and it isn't stopping. Seems like Honda is hoping for warmer weather but that is not right. Please help.

I was driving my vehicle at 25 when it started showing three warnings " collision mitigation system failure, lane departure system failure, adaptive cruise control failure (see your dealer). I called my local hnda dealership in reading pa. They said they have received alot of these complaints and they think they Honda sensing system just freezes in the winter. It only snowed 5 inches a day prior to this event. Basically they said it will go away once its bit warmer and they have no factory recall. All the dealership could repeat " we are sorry". I looked all over the internet and I found 100S of similar complaint. My question is why they are not fixing it" why there has been no recall" the failure of this Honda sensing system defeats the main reason I bought this car along with many others.

Wheel wells building up with ice/snow causing vehicle to vibrate while operating (like out of alignment) and hindering the turning of the vehicle left or right because tires are hitting the ice/snow buildup on wheel well.the tires when cold also behave as if road is slippery, both in acceralation/stopping even though road may be dry. This occurs in cold temperatures only. Dealership states that there is nothing that can be done other than to drive vehicle into a heated garage to allow ice/snow buildup to melt off. This is a safety issue since traveling 15-20 miles in snow conditions and the wheel well is full of snow and the tires are making contact with this snow which will affect the tires as well. Not being able to turn sharply left and right is dangerous not allowing driver to take corrective action need be. Tires appear to be dangerous in cold temperatures because after they warm up, they operate okay. However when cold, the slip and slide behaving like you are on icy roads even though road is dry. Took to dealer today.additional pictures and the invoice from dealership available

The Honda sensing system sometimes automatically slams on the brakes at highways speed when there is no vehicle in front of me, nearly causing collisions with vehicles traveling behind me.

- Little Creek, DE, USA

Loud rattling noise coming from the dash on the left side in the driver's area. Seems to occur at all speeds, regardless of ambient temperature. In December 2018 I was informed by local dealership that Honda working on a "fix" but I have seen nothing yet about a tsb or recall. Noticed noise not long after purchasing vehicle in Feb 2018. Annoying for a new car to be noisy.

In the states where it snows, the car collects large amounts of snow on the front, and knocks out the radar system for the lane departure detection system, witch also is for the braking system, that helps with cruise control and any close encounters. I am not sure if it actually affects the cruise control because in the snow is not a time to use it.

While I was driving on a one lane road with no one else around my sunroof/ moon roof exploded/shattered. According to consumer reports (https://www.consumerreports.org/car-safety/exploding-sunroofs-danger-overhead) - this is a known problem in Honda Accord. The dealer refuses to accept the glass could have shattered on its own and says that its due to an outside influence and will not cover the car under warranty. The car was purchased Sep 18,2018. I had to pay over $1,375.19 for repair.
