Problems with 2018 Honda Accord ELECTRICAL SYSTEM

On january 4th while traveling home my accord was set in cruise control and out of the blue hit the brakes on it's own with no one around me. i brushed it off but about 20 miles or so down the road it did it again except thus te was next to a diesel and not only did brake on its on it also responded as if i was out my lane and began to to turn my car into the diesel i was able to keep the car from crashing and the the cruise control went out and i began to get a message the there was an issue with the braking mechanism. i was worried about driving the remainder of of my trip but i was an hour and half away from home so traveled on home check my brakes constantly. this experience has my wife and i rattled. i took my car in on the 6th to topeka honda and explained what happened and that the car tried to kill me and my wife by trying to run us into a diesel truck and how it was braking on its own and the took and looked at it . the dealership called me back a stated"there was some gunk on your censor and that cause this to happen and they cleaned it off it was fine" but if the censor is on the front off the csr and gunk makes it not work surely this will happen again. i no longer feel safe nor will i allow my wife to operate this vehicle.

Driving at the highway, car suddenly slow down from 70mph to 40-50mph,there were any car in front of me! i have nothing on my windshield! there weren't any stop or traffic sign! so honda stop saying i am driving recklessly! for few second i regained control of gas, i have to speed up my car so i don't get rear end, then everything happen again, car decided to tap brake by itself. this happen multiple time during the highway driving. screen pop up said collision mitigation break system error. please contact honda dealership. after contact dealership for repair. was told that they could not determined the problem since the error did not show up during their in house testing. and yes, error code disappeared after car restarted. but problem consists after long distance drive. i don't know i should drive this car or i have pray you god that one day i don't get rear end because honda accord decides to brake itself!

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 repositioning the car and the engine is on, and the brake assist/anti-collision falsely activating when nothing is directly in the path of the car. all of these happen while the car is operating on city streets and highways.

Vehicle had issues cranking and the display had every error code flashing one after the other. after going to the dealership we were told that it was the fuel pump. it was replaced in july. the exact same issue has happened again in october if the same year and we are being told that it is the fuel pump again.

As i am driving on the freeway, the center screen will turn off and reset itself. this causes my hands-free to stop working if i am on the phone. additionally, i am forced to touch the screen while i am driving in order to connect car play/ bluetooth which is hazardous. this has happened to me on more than 10 occasions.

Tl* the contact owns a 2018 honda accord. the contact stated that the horn was inoperable and the charging system warning indicator illuminated. the vehicle was taken to carmax (2750 stoneridge dr, pleasanton, ca 94588, (925) 600-0741) where the fuse was replaced twice, but the failure persisted. the vehicle was currently awaiting repairs. the manufacturer was not made aware of the failure. the failure mileage was 12,000.

Tl* the contact owns a 2018 honda accord. while attempting to drive, the vehicle failed to start. the "service needed" message was displayed. the vehicle was towed to covington honda (1915 hot springs rd, covington, va 24426, (800) 234-7853) where it was diagnosed that the wiring harness was destroyed by rodents. the vehicle was repaired with a new wiring harness and rodent proof tape. the manufacturer was contacted, but did not assist. the failure mileage was approximately 5,000. the vin was invalid.

Started the car and was immediately received 4 messages: "lkas: lane keeping assist system problem. see your dealer.". "road departure mitigation system problem. see your dealer.", "blind spot information system problem. see your dealer.", "auto high_beam problem. manual controls available. see your dealer.". turn signals did not work. hazard lights did not work. trunk release did not work. backup camera did not work. came back after 30 minutes or so and all displayed failures were gone and the trunk opened. my daughter said the brake lights were functioning when i depressed the brake and even though the backup camera did not turn on the back up sensors appeared to be operating.

Tl* the contact owned a 2019 honda accord. the vehicle was parked, when an explosion was heard. the vehicle had caught on fire. the police was not present and there were no injuries sustained. the fire department extinguished the flames. the vehicle was destroyed and towed to an impound lot. the vehicle was not taken to the dealer for a diagnostic testing. the manufacturer was notified of the failure and a complaint was filed. the approximate failure mileage was 20,000.

For a while now, im noticing that the auto high beams on my 2018 honda accord ex-l 2.0t car isnt working. i've tried reseting the display audio unit, i've tried disabling/re-enabling auto high beam feature by pulling the high beam stick on the steering column - none of this has fixed the issue. basic obd2 (via bluetooth and android app) do no indicate any fault codes. will be taking this into the dealership to have it checked out.

I was driving on express way on 7/5/19 early morning. the car shake and slow down all of the sudden. i would be killed if there's a car behine me. i pulled to the curb, and try to restart the car and go, but it keeps shakung in the beginning. so i called honda for tow truck, that a leased car. but later i tried again, it seems the car could go, so i drove home. check engine light was on for few days, and the transmission couldn't shift smoothly since then. looks like a lemon. only 9000 miles on the car. i have more pictures about the problem but the system won't allow me to upload more than 5

Tl* the contact owns a 2018 honda accord. after the contact secured his child in the vehicle and closed the passenger door, the vehicle locked without warning. the contact was unable to open the door with the key fob. the fire department was called to open the vehicle and rescue the child after approximately twenty minutes. the vehicle was taken to honda world (13600 beach blvd, westminster, ca, 714-890-8900) where it was diagnosed that the failure was caused by the main modular unit. the failed part also caused other electrical components to fail. the vehicle was not repaired. the failure mileage was 6,000.

Have automatic braking and lane assist driving. brakes on its own with nothing in front. happened twice. dealer calls it a glitch. i call it very dangerous. police officer was behind me when it happened last. good thing he had good reflexes and the speed limit was only 45 mph i was in the center of my lane with no obstructions, no vehicles coming from the opposite direction. turned off the program and haven't used it since. service department said would have to keep car and test drive until it occurred. i will do this, but am afraid they will be keeping the car for awhile because it happens out of the blue. it's happened twice in a period of two months. i have had the car for four months. another problem..paint is spotting on car like it was hit with acid. had protective wax put on the week i purchased it. vehicle has 3500 miles on it. paint also shows tons of orange peel. i paid a lot for this model. expected more.

With only 8200 miles and 5 months on the road, original battery started to leak and twice experienced a time when push button start would not start the engine. stranded. once the problem resolved itself f after 20 minutes. the second time required a jump start to get the engine going. no problems once the engine got started. replaced leaking battery and problem has not returned.

Catastrophic failure. turned vehicle off, noticed alarm did not work. hours later tried to enter car and noted the following: trunk will not open, doors except for driver will not open, turn signals do not work, no high beams, all mitigations systems offline, brake system failure, back up camera doesn't work. thank goodness experienced driver could get it home and/or i was not far from home with vehicle. said car is less than a year old and has 10k mileage.

I have experienced a number of issues with the 2018 honda accord sport, related to the engine, transmission, head unit, brake hold system, noise (tire and poor sound insulation) as well other issues which are described in the attached document.

Collision mitigation braking system goes out for no reason and shuts off automatic cruise control. have to restart car to reset. has occurred on three occasions. i have 10,000 miles on the car, but don't use acc much since most of my driving is in the city. happened on long distance trips on freeway. going 70 mph.

On 2/14/19, i was driving on a city street in a straight line at approximately 40mph. the car ahead of me stopped. i stepped on the brake and instantly the dashboard warnings lit up - adaptive cruise control, collision mitigation braking system, road departure mitigation system, and the brake - and the brake did not work so i could not stop. i rear-ended the car in front of me doing significant damage to the front of my car. the warnings were still visible after the crash and i took pictures of the dashboard as best as possible. the warnings say something about system not working and to see a dealer. the same warnings appeared on 2/13/19 in the afternoon but disappeared on 2/14/19 in the morning. other warnings of safety systems not active have appeared due to ice/slush but then cleared when the sensors were cleared, but these new warnings are different. at least twice, maybe three times in the past few months, the car would suddenly brake and slow down with nothing in the road or in front of the car. my bluetooth connectivity worked fine for first 2-3 months but then stopped and i couldn't reconnect the phone over the past two months. it seems like more than one system/electronics problem and seems like the warnings appeared at the same time as the brake not working as if it was more than an alert but a system (systems) no longer functioning at all. the brake worked after the accident when the car was restarted.

Collusion control does not work consistently while in motion and does not recognize children when stationary

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.

Leased 2018 honda accord in october, 25 miles later had checked engine light on,took it back to the dealer,emission hose wasn't attached properly. after 900 miles the wheel alignment went out ( i did not hit any pot holes) took it back to the dealer, according to the dealer one the rod wasn't set right, now it's january 2019 and have 4000 miles yesterday the car started to supporter and all the warning started flashing auto high beam, adaptive cruise control, collision mitigation, road departure mitigation....all this sing said see your dealer..guess what i called the dealer first thing this morning..today is january 24 2019 still waiting to hear from the dealer all this technology is totally useless... i had 2002 honda accord with 310,000 miles and no technology

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.

1) when depressing the brake in motion or from a parked position there is a 'clicking' noise that happens intermittently. it sounds like a gear is stuck or something is stuck. it doesn't happen every time but it happens often enough that it is noticeable and does not sound like a normal noise. 2) honda sensing light will flash even when no object is approaching and will continue to flash.

Collision mitigation braking system problem while on cruise control it will disengage and this error will show up also braking light flashes on and off with nothing around or near the sensors.

Since the vehicle reached approximately 5000 miles, i had a massive safety failure of the "honda sense" system shutting down, hazard & turn signals inoperative, power locks inoperative, brake system warning light on, loss of auto headlights and information screen. vehicle was taken to the dealrship and they retrieved trouble code which is a "mystery code" that honda does not know why its occuring .... radar told car to accelerate when vehicle was not in motion u0401-92 along with 3 other codes. dealership showed me printout from computer but customer receipt said reset system only and did not list out trouble codes (4 codes retrieved) vehicle now stops intermittently while driving at highway speeds, pulls itself out of the lane while driving, and apple car play system no longer will recognize iphones (tried multiple) and dealer has verified issue but just resets. infotainment screen lost power and set warning message for same when dropped off again at dealership 2/26/19. dealer in florida also had car, said nothing wrong, could not duplicate and vehicle never left dealership and carplay did not work after they claimed it was fine. also found that entire system was reset and rebooted, causing loss of all settings and stored information/stations....why reboot if its working? vehicle now being driven with honda sense system off due to fear of collision or accident caused by vehicle and not driver. this vehicle is now unsafe to drive. multiple complaints about vehicle braking on its own, flashing "brake" warning to driver when no car in front ... happens local and highway driving now intermittently. vehicle has been in dealerships approximately 4-5 times since inital electrical failure 12/24/19. email contact and several phone calls to hma already. original electrical failure happened 12/23/28 and i have been dealing with since. also have snapshots

Infotainment screen which also displays rear view camera randomly restarts.

Last service check, approx 1 week, showed battery partially discharged (marked as "failed" and "replace" on the service report. no apparent reason. today, after a rainy day and not using the car the day before, found the car locked as always but all four windows were down. this is the second occurrence. the first time was 2 months ago when a neighbor called to tell me the windows were down. the car was locked then as well, it was also after a rainy day. in both occurrences, there was no water in the vehicle or on the seats.

Vehicle was stationary and off .doors would not unlock with remote or manual. only driver's door with the remote. also auto lock/unlock didn't work in park and drive. started the car and the instrument panel flashed warnings of: lane keeping assist system problem. see your dealer., road departure mitigation system problem. see your dealer. auto high beam problem. see your dealer. automatic lighting control system problem. see your dealer. i let the car sit for a half hour. doors unlocked with remote with no problem. started car and all was back to normal. took the car to my honda dealer to advise them of this issue and showed them a youtube video of other owners who had the exact same issue with no explanation of why or remedy. my honda dealer had not had anyone else come in with my cars issue as of today 11/30/2018. honda dealer checked my battery and it is perfect, 12.3 volts, measured:640cca, rated: 550cca. my car has only 6,388 miles, purchased 5/23/2018. pretty scary and not happy this has happened with a new car.

Re: nhtsa recall 18v-629 dealer reprogrammed the display audio unit, as required by the recall. the reprogramming failed to solve the problem, in fact, it made it worse.. the display now starts and reboots at random while the car is being driven, including when it is in reverse. the service manager told me that he has the same problem with his own 2018 honda accord. the problem only occurs when the car is in motion.

Since purchasing the vehicle in july and especially over the course of the last two months the car has been exhibiting errors with the cpu (honda sensing) system on board. the transmission also seems to exhibit issues which i have taken up with the dealership on two occasions where it appears to shift hard under light acceleration and even under passing power. also, upon accelerating, the car will seem to bog down like it has a air intake issue(sensation feeling) it does it from stop and go at times and also when at speed. i have noticed that when it rains it seems to be even more pronounced as well. the other issue has been the honda sensing. as of late i have found myself turning off certain "safety" features out of fear of them malfunctioning after two freak incidents. twice when at speeds on the hwy, the emergency mitigating brake has engaged with no traffic around or in front me, basically slamming on the brakes which is extremely dangerous another time the steering has tried to yank me into another lane thinking i have gone off the road, the road mitigation system. these issues could have proven very dangerous in both situations if vehicles were next to me or behind me and these issues with a brand new car are not making me feel safe to drive the car. also, another new item which i have caught on camera is the radio head unit has now began to shut off intermittently during normal operation for no apparent reason or cause. i have had the recall on the back up camera completed already. but these errors still continue. the car is going to the dealership on thursday, 11/7/2018 to get these looked into, but this is the 3rd time the car has had to go to the dealership since purchase in july for non regular maintenance. i am going to only deal with this a few more times before i hire a lemon law attorney.

The car has a sensor for breaking. on several occasions i have been driving and the car breaking system comes on making the vehicle come to a sudden stop. during several of these dangerous breaking events no vehicles or objects were in front of me. i have almost been rare ended because of the breaking. i have noticed that even s shadow from a tree can trigger the sensor to make the breaking system turn on making the car come to a sudden stop. this is extremely dangerous and there is no way to turn this feature completely off. when you turn it off it resets once you turn the ignition to start the car again. this recall needs to happen now before someone gets injured or killed.

5 braking error messages appeared after being parked for 4 hours: electric parking brake system problem, brake system problem, brake hold system problem, anti-lock brake system problem, vehicle stability assist system problem. all errors directed me to "see your dealer". the vehicle operated perfectly prior to this. i was unable to start the car or even lock it after these errors appeared. the battery was also drained because these messages kept appearing.

Reverse camera quit working and auto matic breaking bros out alpha known when using cruise control

Faulty backup camera. while backing up hit a car and honda is not taking any responsability.

On several occasions this cars collision mitigation system has applied the brakes without any reason and this is a very serious safety issue for the public at large and needs immediate attention from honda. i've seen some complaints about the 2017 and 2018 crv doing this exact same thing.

The car randomly slams on brakes caused by the honda sensing collision mitigation system. this is very dangerous

Windshield wipers wouldn't work while driving in rain on highway. pulled over, went to service station, they had me turn car off and checked some fuses. then warning lights came on about the vehicle stability control, braking and various safety features. this morning when i started car and backed out of driveway the wipers started working but the warning lights are still on. took it to dealer this morning.

Two computer screen issues: computer screen would list several warnings (brake system, lane departure ,blind spot indicator ,lights all shown to be a problem. trunk & turn signals, iphone connection were inoperable.car was stationary.

On a hot day while sitting stationary in my car with ac running, i heard a 'pop' with a fizzle sound then smoke began to rise from the front of the dash where it meets the windshield. the vehicle stopped running [push to start], and all lights flashed on the dashboard. the all sensors began to emit error messages. i turned off and exited vehicle, popped the hood and smoke was also coming up from outside the car. the car was purchased in march 2018, and at time of incident had a little 6000 miles. after letting car sit for a few hours it started up, with error messages across the display..i.e. tpms, check engine, lkas,etc. i then had vehicle towed to nearest honda dealer, and the service people were unsure why a module in the dash burnt out; so they contacted honda corp. long story short they placed blame that a charger found in the bottom of my glove box caused it, which was never used in my car. to this day no one can answer me why a spontaneous fire started in my car while sitting still with ac running, but they refused to fix my car. this could have been a serious issue if the car was being driven at the time of this incident. photos show possible leakage on the wires, but no on wants to admit that there is a big problem at hand.

Trunk would not open, blinkers and wipers would not work, all on board sensors (lane departure, backup detection, etc.) would not operate. several error warnings presented on dash in regards to safety sensors not working. had to stop at dealership and they reset the car computer. safety issue w/wipers and blinkers not working.

Tl* the contact owns a 2018 honda accord. the contact stated that the vehicle went into limp mode and the engine warning indicator randomly illuminated. the vehicle experienced a loss of power more than twice while making a turn and driving highway speeds. the contact had to coast the vehicle over to the side of the road, and shut off and restart the vehicle. waikem honda (3910 lincoln way e, massillon, oh 44646, (330) 477-5002) was unable to duplicate the failure or locate a diagnostic trouble code. the dealer and manufacturer technician test drove the vehicle, but found no failure. the vehicle was not repaired. the manufacturer was notified. the approximate failure mileage was 4,000 and a second time around 7,300 miles.*bf consumer stated when the goes into "limp mode" and i cannot accelerate. if i were in the left lane passing a semi, i could visualize this a fatal accident. i am anticipating another "limp mode" soon as i have just over 11,000 miles and it seems to happen about every 3 to 4,000 miles. *jb

Tl* the contact owns a 2018 honda accord. the contact stated that the tire pressure monitoring system (tpms) warning indicator illuminated when the ignition was started. the vehicle was taken to an independent mechanic where the contact was informed that the tires were perfect and the tpms was reset, but the failure recurred. the vehicle was not taken to a dealer for diagnostic testing or repairs. the manufacturer was made aware of the failure and informed the contact to take the vehicle to a honda dealer. the failure mileage was 35,000.*jb

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.

1. car multimedia unit (with a touch-screen) randomly freezes and restarts itself. it happened to me 9 times already since i bought a car in june 2018. if you use navigation system or need screen for other activities while you driving - you are in trouble, because you will lose all the content you had on the screen before the restart and it will distract you from the driving. after restart system is very slow and it forces you to accept legal declaimer while you driving! two times it just froze without restart and i had to stop the car, turn the engine off and on again, to remove the problem. very annoying and also not safe because it distracts you. one time it happened while i was backing up using rear view camera, which almost caused an accident. this happens randomly, mainly when i'm driving. it happens when devices are attached to the multimedia unit and without any devices being attached or used. it happens at night and day time and i doubt it is related to overheating. it can happen during long drive as well as 5-10 minutes after the engine start. no visible pattern here. ocean honda of burlingame dealership in bay area is not helpful and totally not professional. been there twice, no luck. they didn't even try to replicate the issue properly always trying to search for fault in my actions or blame compatible devices attached to cigarette power slot. american honda advised me to video record this activity while i'm driving !!!! still no resolution. very disappointed in honda 2. sensors are not properly setup because it "thinks" that there's a car ahead of you if sensor detect shadow on a road, etc. car applied breaks few times without a reason. didn't go to dealership with this problem yet.

All honda sensing lights goes off and see the dealer message shown on screen.

On 3 seperate occasions the car has seen a shadow on the ground and slammed on brakes then releasing for no reason. there were no other vehicles around me on each occasion. i thought the car was stopping on a yellow light on the first incident but was told by the service manager that it doesn't do that. this is a very dangerous issue that needs to be addressed. i asked the service manager to disable it but was told he can't do that when it is possible because this is an added feature.

Tl* the contact owns a 2018 honda accord. while driving 30-40 mph and making a left turn, the lane assist system and lane mitigation warning indicators illuminated. in the middle of completing the turn, the lane mitigation feature activated and steered the vehicle to the right. as a result, the vehicle struck a boulder and fractured the front passenger side suspension, which damaged the body of the vehicle. a police report was not filed and there were no injuries. the vehicle was towed to coral springs auto mall (9300 w atlantic blvd, coral springs, fl 33071, (954) 369-1016) where it was diagnosed that there was a miscommunication between several of the safety features. the vehicle was not repaired. the manufacturer was contacted. the approximate failure mileage was 11,000.

Tl* the contact owns a 2018 honda accord. while driving 70 mph with the adaptive cruise control function engaged, the vehicle decelerated. the contact stated that the failure recurred several times. the contact stated that the instrument cluster blacked out on several occasions. the vehicle was taken to zimbrick honda (located at 1601 w beltline hwy, madison, wi 53713, (608) 273-2555) to be diagnosed, but the mechanic was unable to retrieve a fault code or duplicate the failure. the vehicle was not repaired. the manufacturer was contacted. the approximate failure mileage was 2,000.

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.
