I was accelerating from a stop at a red light and once I hit about 10-15 mph, the collision mitigation system came on and slammed the car to a complete stop for no apparent reason. I have a dash camera video which shows the incident. This was on a clear, sunny day on a non-busy city street (overpass).

The vehicle had a sudden loss of function in: 1. road departure mitigation 2. collision mitigation 3. adaptive cruise control 4. braking system the vehicle was in motion at speed of 10-40mph, with air temperature of 28-32 degrees and snowy conditions. Honda has repeatedly refused to investigate numerous, potentially sw/hw - related issues that have been manifesting themselves in other parts of the vehicle. What happened today was a new set of symptoms, but with much higher severity and no obvious precedent. I have already had to disable the lane departure and the collision avoidance systems on this vehicle due to their erratic behavior. However, in this case the messages that have come up (will attache photos) demanded that the vehicle be taken to the dealer and the errors and message did not go away upon multiple restarts of the vehicle. Upon arrival to the dealer, it was indicated to me that Honda is aware of some of the other issues I've been experiencing with the vehicle and still (months hence) does not have a fix, and that Honda has, essentially, been resorting to testing their vehicle on the customers, instead of more rigorous pre-release testing, instead choosing to use the dealers as a quasi-test/R&D department. The multiple safety system failure I experienced today is a pretty clear indication of that. I have filed another complaint with nthsa related to the other issues and would urge you to initiate a recall on all of the Honda Accord (and possibly Odyssey and Pilot as they share some of the sub-systems) for the 2018, 2019 and the coming 2020 models.

The vehicle makes a drone like humming noise. Dealer says they are unable to duplicate and I should report the problem to Honda. Noise happens intermittently when driving car at all speeds.

After being parked in a friends driveway for several hours I proceeded to open my car and drive home. First remote control would not open doors, after several tries it open the driver door only, upon turning ignition on a series of warning indicating the adaptive cruise control system automatically disables itself, all collision mitigation functions stop working, series of warning see pics appear on display to see dealer, all windows and truck will not function, turn signals and brake lights, rear view camera do not function, brake system msg appears on display. Turned off and on car with no success in restoring all functions as on two previous occasions. Drove car for 4 miles in this state felt it was dangerous for us and other drivers. This morning all has restored to normal. Called Honda dealer in el monte ca. Was told they did not know anything about this type of problem, was not able to book service call until middle of next week in researching online found Honda service bulletin 19-051 describing a software update to car modules to fix this problem. I believe that is really should merit a recall as it interferes with the safe driving of the vehicle. A recall will force Honda to inform its service dealers and instruct them on a prompt scheduling of required software upgrade to resolve this software defect affecting drivability of their flagship car.

Collision mitigation system does not work; initial issue was warning systems went on with no one in front of car. Second time brakes were applied to vehicle with no one in front of car, leading to car induced panic stop on road, thankfully, no one was trailing my car at that time. Honda test drove and could not find anything; since this is sporadic, this was not surprising. Told them it is a very dangerous condition and that this is a well documented complaint on websites; they told us we can turn off front mitigation collision system each time we drive. Requested dealership general manager to report this condition to regional director at Honda

My vehicle's backup camera software has failed again despite being "fixed" once already. The vehicle was recalled in 2018 to fix defective software that caused the backup camera to not function properly. The camera's collision sensor quit working and failed to warn me of objects in my path when I was backing up. Honda loaded new software, but the problem has persisted. I took it back to the dealer for another repair, but I got the same old song and dance... "gee, it's working fine for us, and we can't fix it if it ain't broke!" well it is broken, and Honda won't fix it. This is a serious safety issue, and I hope the NHTSA can help me get it resolved.

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.

Observed spots on the bonnet where the paint has peeled off. The car was purchased bought in Oct 2018.

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.

- Irvine, CA, USA

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.
