The vehicle has been giving a check engine light and a litany of other warning lights including: electric power steering system problem, brake system problem, forward collision mitigation braking system problem, tire pressure monitoring system problem, adaptive cruise control system problem, traction control system problem. This issue happened intermittently at first including the warning lights, then constantly beginning about 3 weeks ago. The check engine light produced a P0304 code indicating a misfire on cylinder 4. The vehicle on cold start would idle rough indicating the misfire and idle at a higher RPM than normal. The vehicle would return to idling normally after approximately 15 minutes of warming up however all the lights would stay on. The vehicle felt like it was down on power, was running rough, and could go into limp mode at any time while the issue was present and significantly reduced the driveability and all of these other warning lights were on indicating potential problems with those systems. I had the vehicle inspected by a Honda dealership and two different master technicians have diagnosed it as a fuel injector issue, although they thought it could have been a head gasket issue as well and in fact have not ruled that out entirely at this point. This is a known issue with this vehicle shown by AHM putting out a request for parts from 2018-2019 1.5 Liter engine Accords affected by a P030X (Cylinder 1,2,3, or 4 misfire) code back in April.
2018 Honda Accord electrical complaints
Page 6 of 11: complaints 131 to 160 of 297, newest first, as owners wrote them.
Center display system that controls all audio and visual for GPS, and system controls abruptly will shut off and create a loud crackling sound in the speakers. The not working for hours or days.
Began getting several alerts, when taken in to get a diagnosis I received the following error codes P0301, P0304, P0301, P0300, U0401-68 & U3003-16. These codes stated that I had Cylinder 1 Misfire, Cylinder 4 Misfire as well as Random Misfire and ECM Failure and Electric Parking Brake Control Unit Power Source Circuit Low Voltage. The misfires were taken care of with new ignition coils and spark plugs; however, 2 days later alerts came back on at that point replaced battery. A few days after that the alerts again came back on. The dealership has not helped me out much simply saying I am no longer under warranty. However, I feel this vehicle is unsafe to drive as sometimes it feels as if it is just going to shut off. Therefore, this can possibly cause an accident injuring either. Others or myself.
The infotainment unit on the 2018 Honda Accord does not properly sync up with a music player on the phone over Bluetooth. This is manifested by the incorrect display of the time the music track that has been played. This happens periodically. At other times, the music player on the infotainment unit does not respond to the tracks been switched from the controls on the steering wheel or the touch screen. A video of the behavior is available. Additionally, he infotainment unit does not display the album art for the music which is being played. This feature used to work, until the phone update. Which indicates that the infotainment unit does not properly work with newer Bluetooth protocols. Upon an attempt to troubleshoot the issue, based on the information here: [XXX] [XXX] I was able to restore only the track information being displayed, but not the album art. This is troubling as this would indicated that Honda has built in infotainment units without a seeming path to upgrade them during the life of the vehicle. Honda has been unwilling to properly address the issue via a recall or a software update. Their typical response (to just about every issue) is to take it to the dealer, who is not able to properly troubleshoot and address issues which were caused by the Honda's failures in software (and hardware) development. A video of the issue is available (Honda dealer and Honda pretty much refuse to take the videos as an evidence of the issue).

All dashboards lights is lid and comes off and on and intermittently electric issues... also horrible horrible all or most person who owns car complaints of underboost turbo charger and had to replace the turbo charger including myself and blown gasket.... causing a major sever safety issue especially driving....
I was driving slow to a 4 way st and slowly had a car pass across me so far away and it passed and all of a sudden emergency break and slam on break by itself causing the passenger in my car to hurt them self ... I was unable to control this accident so bad!!!!
Starting in Sept 2023, while pulling out of a park in a garage, my car started throwing numerous warning messages in the dashboard regarding emissions, ABS, Brake System, Power Steering, etc with the Check Engine Light staying steady. I took it to one Honda dealership who after 'diagnosing' claimed it was the fuel injectors needing to be replaced. The car wasn't jerking or sputtering so I took the car to another mechanic who also didn't believe it was the fuel injectors and felt it was electrical. Took the car to another Honda dealership and they claimed the same thing about injectors. After having a reputable mechanic do software updates that the original or 2nd Honda dealership NEVER checked for (it needed 4 updates, but one of them couldn't be done for LKAS). Most of the warnings went away due to the updates but the LKAS warning and collision warning remained. So I took the car to Safelite (they had replaced my windshield back in July and back then they were able to recalibrate the sensor) BUT this time (Oct 2023) not only were they not able to recalibrate the LKAS, they said the front camera was not communicating with the system and this was an electrical problem and I have to go back to the dealership. After reading NUMEROUS complaints and similar issues in regards to the LKAS, this multiple warnings AND the car ghost braking on its own every now and then months before this, I hope you all really look into this and do a recall or find a solution on this car. Now I am forced to go back to the Honda dealership and will have to threaten them to do their job this time and really look at the car and not just tell me it is needing fuel injectors replaced. The car drives, no jerking, no sputtering, but not having a front camera talking to the system and now the TPMS system keeps saying i have low tire pressure and won't let me calibrate even though my tires are at the optimal 32 level stated in the manual, I fear more issues are going to pop up soon.
All electrical warning lights came on dashboard. This is very frustrating and scary. This needs to be a recall on this vehicle because nothing this serious is normal. I thought my car was falling apart. Honda needs to fix this problem and the owner should not be responsible.
The lights on this car pops up weekly sometimes when im driving pass 40 mph my car will just shut off. My brake hold button works on in off since ive gotten it i constantly get warnings like brake system problem, tire pressure monitor system problem, electrical prower steer Problem, acc problem, emissions problems all at once i have taking it to the dealer plenty of times but the problem never gets resolved i have been in almost 5 accidents due to my car just losing power
The warning lights appear out of nothing and the issue has happened without an incident. I’ve been scared to drive my car with all these dash lights on. I don’t feel safe and I don’t want to put my life or kids life in danger.
The contact owns a 2018 Honda Accord. The contact stated while driving 70 MPH, the vehicle stalled. The contact was able to park the vehicle on the side of the highway; additionally, the hazard lights failed to work. The vehicle was taken to the dealer, who informed the contact of a faulty START/STOP switch. The contact stated that while driving at an undisclosed speed, the vehicle sporadically applied the brakes independently. Additionally, the contact stated that while driving at an undisclosed speed, the vehicle lost motive power and the hazard lights failed to function. The vehicle was taken back to the dealer, where the contact was informed that the START/STOP switch needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 75,336.
I was driving on the freeway in Houston, TX going 65 mph in the middle lane and my engine begin to lose power, and start stalling. Almost causing me to wreck with my 8 yr old son in the back seat. I was advised by my the dealership that Honda has a recall on fuel pumpt with my year and model. I contacted Honda and was advised my car is the year and model of the fuel pump recall, but it wasn’t effective by it. I feel that’s very strange my car didn’t apply to the recall, but it’s doing the same thing other owners car doing with the faulty fuel pump recall. I am terrified by the incident and it has cause me so much anxiety and stress. I look to get my car repaired due to the recall and Honda isn’t being helpful after myself and child almost had a wreck
All lights are on saying turbo is goingout on scanner
In the multimple other complaints filed (regarding the Collision Mitigation System, Infotainment, etc.) it become obvious that Honda has really screwed up the firmware/software and how it interacts with the sensors/systems and the user on this vehicle. The issue, this time, was the common occurrence of the battery dying. HOWEVER, instead of simply putting up a message that says "Hello, your battery is in an untennable state", someone thought it would be a good idea to flush EVERY warning possible, as in "Anti-Lock Brake System Problem...", "Vehicle Stability Assist System Problem...", etc. And, of course, it would demand that you "take it to the dealer." Upon replacing the battery the issues went away, for a few days. Then, another set of warnings - this time, something to do with the "Emission System". Upon taking it to a non-Honda reputable mechanic (so, a third party without a conflict of interest), they reset the codes and then things seemed to settle down. Good to know - another thing that just "happens with these" when it comes to the Accords of the 2018+ model year.
The vehicle keeps stating the brake mitigation, acc, and other various Honda sensor features need to be repaired and to contact a dealer. The vehicle de-accelerates on its home and doesn’t allow any of the Honda sense features to work. All the components of the dash are triggered at once. Most of the time the vehicle drives fine without the use of the Honda sense features. I have brought this to Honda and they state they don’t see any issues known to cause this problem. Short of the fact they never seem to happen when I bring it to the dealership. Most of the time this goes away on its own but lately the problems are lasting days. I don’t feel safe driving my own vehicle which has been greatly maintained.
The contact owns a 2018 Honda Accord. The contact stated while starting the vehicle, the Adaptive Cruise Control (ACC), TPMS, anti-theft system, braking system, and traction control warning lights illuminated, and the messages "Collision Mitigation Braking System Problem. See Sealer", "Road Departure Mitigation. See Dealer" were displayed. The contact stated that the adaptive cruise control (ACC) mode, the Econ mode, and Sport mode were inoperable. The contact stated that she turned off and restarted the vehicle, and attempted to reset the vehicle herself; however, the failure persisted. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 88,697.
Everytime I drive my car for a few hours the EPS light comes on and I have to pull over and turn my car and on. I have reached out to the dealer and they refuse to fix it. It has been happening for about 2 years. Close to 3.

I was on a hill my car stalled I hit the gas pedal it wouldn't accelerate so I let off the padel and went to try to accelerate for the second time but as I did it took off and I hit a pole
1. The Collision Mitigation Breaking System is braking for no reason, at random times while driving 2. My safety and the safety of others is put at risk because when driving on an open road, cars behind me may not have time to break and this could result in an accident. Not to mention, there's nothing in front of my vehicle, so normal things on the road don't cause drivers to assume a car with suddenly brake 3. Yes, the issues been confirmed but I'm expected to pay for it when this has been recalled on several other models 4. This has been happening for the last several months. I put a note in my car to turn off the sensor but as of today, my vehicle will not let me turn off the sensor anymore

Door lock actuator Door does not auto lock leaving my rear passenger door unlocked even while driving. Has not been inspected as it is out of warranty
Out of the blue car was having a glitch on the screen when turning on the vechical. The battery died and was replaced. Once battery was replaced engine light and brake like will turn on and off. After battery was replaced the engine light turned on and started to read that ignition and sparks plugs are bad. I have spoke to about 50 people with the same car and they are having the same issues and the mechanics do not know what is wrong
Door locks malfunctioning intermittently across multiple doors. Locks cannot be toggled by master control or fob. Passenger in seat of defective lock could be trapped in vehicle in emergency if unable to manually toggle door lock. I have fixed one lock only for the issue to present itself on another door lock immediately after repair.
Vehicle suddenly shut down in traffic second time in a row within 4 days after it was supposedly repair by Honda dealer the first time. It was again my luck that the car engine shut down, suddenly stopped on a road, not on a highway which could result in serious injury to death as sudden stop would cause newsworthy bad crash to my vehicle from oncoming high speed traffic that follows my vehicle. Problem was traced to the latent defective wire harness bundle that runs from the front to the rear of the vehicle throughout the floor board. I believe normal vehicle road vibration during my four years of driving in the high traffic Los Angeles region (a measly 27,700 miles) introduced flexing to the wire harness at certain portion of the latent defective wire harness bundle. The latent defect in the wire harness bundle surfaced its ugly head finally since I own the car new in March, 2019. A segment of the spider wire harness bundle that has the latent intermittent defect disconnected internally to cause the control signal to the fuel pump assembly to stop fuel pump to the engine. Consequently, the vehicle engine shut down, stopped suddenly in traffic again the second time due to lack of fuel. The large spider wire harness bundle was replaced on May 9, 2023. The vehicle is operating properly so far. Clearly this is not a wear and tear issue. It is a latent defective wire harness bundle supplied to Honda by the Honda subcontractors who fabricated the wire harness bundle for the factory build for this 2018 Honda Accord model lot. I like to strongly urge the federal safety agency to engage Honda to make plans to investigate this lot of wire harness supplied to it now that my vehicle defective wire harness bundle is sent back to the Honda warranty department.
the vehicle has faults on the dashboard, all the warning lights come on and there are functions that do not work when they are on.
I down loaded my update through the radio. It said complete. I went into the house and the next morning I started it and a bunch of warning lights were on and have stayed on. I can not use some of the buttons on the drivers door, I can not use my key fob unless it is touching the start stop button, I can not open the trunk, the gas cap will not open, and most of all I have lost some power to the interior fuse box. This car is only 5 years old almost to the date and it has had multiple recalls already. I want the BCM reprogrammed and fixed so all this will go away.
Door locks don’t work with fob intermittently. Often times, failure door can only be locked/unlocked manually by toggled physical mechanism, or by use of key, never buttons or fob. Passenger using said door would have difficulty opening door in the event of emergency, or at least delayed in doing so trying to find the toggle. Issue has not be replicated by either dealer or other professional. Issue has been ongoing for 6 months, but recently one of the door has failed completely so I will be going back to dealer tomorrow. There are no warning indicators to suggest a certain issue.
The infotainment unit on the 2018 Honda Accord does not properly sync up with a music player (such as any given phone) over Bluetooth. This is manifested by the information from the previous track being shown while another track is playing. Honda has been unwilling to properly address the issue via a recall or a software update. Their typical response (to just about every issue) is to take it to the dealer, who is not able to properly troubleshoot and address issues which were caused by the Honda's failures in software (and hardware) development.
