Recently reported UNKNOWN OR OTHER problems on 2018 Honda Accord

This car almost killed me on highway while driving 70 miles/h it decided to tap breaks by itself(slow down) the gas pedal would not respond it was not any car in front of me.i took it to a dealer they restarted the system said everything it's fine now but did not fixed the problem the same day i had the same issue with it.i don't feel safe driving in it.

Vehicle was parked/stationary on semi-flat a school parking lot. when i looked back the vehicles moved. seems the parking gear did not fully engaged. regardless vehicle was not in neutral or drive and it still moved forward with no one on it, no keys inside and engine off. vehicle hit another parked vehicle. luckily no one got hurt. seems that the transmission/cvt system may be at fault, but unknown at this time.

Repeatedly at random intervals during hot & cold weather i hear loud buzzing vibration sound coming from area housing high voltage lithium ion battery!!! over the past one year. always while driving at 46 to 52 mph, now in cold weather is starting at 35 mph . i fear over heating or fire from high voltage lithium ion battery!!! i had the dealer replace a mic located in the cabin and not problem was corrected, 7 different technicians at honda had hear this noise but they don"t know what it is. this is been happen since the car had 4200 miles now is 28000 and is getting worst . please if you having this similar issue take the time to report it here so honda can take it serious this can be a fire hazard .

Here is a description of the safety issues this car continues to have that the manufacturer and two dealers will not fix under the manufacturer's warrantee because they claim they can not duplicate and there are no stored error codes. this car has a lane departure mitigation (ldm) system that has falsely activated many times while the car is centered on the driving lane. the ldm activates by providing a warning on the dashboard and by moving the steering wheel quickly to the left and to the right which distracts the driver (a safety issue) and once caused me to almost steer the car into a semi on my right by compensating for the left steering wheel movement. this car also has a lane keep assist system (lkas) which repeatedly has steered the car off the road. both these issues have been recorded and provided to ahm and both dealers. these issues happen randomly on city streets and highways. additionally, this car has issues with randomly displaying an incorrect speed limit on the dashboard (100 mph in a 60 mph zone), falsely warning "steering is required" on the dashboard, a "shift to park" warning while ...

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, ...

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.

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 ...

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.

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.

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.
