2021 Honda Accord Electrical System Problems

4 out of 5 times driving the car the infotainment screen with get random touches guiding you to unknown menus or system setting or maybe just to a different radio station. Where I think this becomes a legitimate safety concern (asside from changing vehicle settings like security) is when trying to use maps function the random touches will direct the map away from where you are or where your next turn might be. So you basically need to keep hitting re-center just to get you back on course. However most of the time there is an uncomanded touch that is stuck on the screen or possibly a number of touches that prevent a real finger print touch to be sensed ultimately preventing you from re-centering. This causes extended moments where attention is taken away from the road or late/last minute route correction causing unsafe road/driving conditions. The manufacturer only recommends doing a system restart of your infotainment screen which does nothing or complete replacement of the screen which in many cases including my own is not covered by warranty.... the alternative is to disconnect your phone from android auto or apple car play and use it in your hand which again causes distracted driving. If this was something as simple as a volume knob or temperature control not responding I wouldn't even be here but since it always touching different placed and navigating you places you dont want to be i see it as a clear safety issue that should be corrected. Thanks

The lights and warnings below popped up on my dash after the engine light had come on and then off again for about a week. See below, -Emission system problem Avoid heavy acceleration and high speed. See dealer -tpms light -brake system problem -brake hold system problem -electric power steering system problem -vehicle stability assist system problem -hill start assist problem -adaptive cruise control system problem -collision mitigation braking system problem -road departure mitigation system problem Went to get diagnosed at the dealership and was told that the turbo on my engine had failed. Mechanic said it had nothing to do with me and that it failed on its own. I saw that it was a reoccurring problem with other Honda owners with the same year, make, and model as mine but are being given the run around and no solution.

ssue: Water intrusion into tail light assembly causing electrical and safety system malfunctions Status: Repaired at owner expense (~$800) Concern: Safety‑related defect and potential pattern across vehicles Description of the Issue: My 2021 Honda Accord experienced a failure where water entered the tail light assembly and caused electrical shorts. This resulted in multiple safety‑critical system warnings, including brake system alerts, ABS/VSA warnings, and Honda Sensing failures. The vehicle also lost acceleration and entered a reduced‑power “limp mode,” creating a hazardous driving situation. The dealership diagnosed the issue as water intrusion into the tail light assembly. The entire assembly had to be replaced at a cost of over $800. After replacement, all warnings and drivability issues resolved immediately.

This has been reported one time before but the situation has gotten worse when driving at approximately 60ish miles per hour but it starts doing it about between 50 and 70 mph when driving and the car is using the regular engine not the EV section. You will randomly lose the ability to accelerate and you have to remove your foot from the gas let the engine slow and then re-accelerate now for the second time as I'm driving I lose the ability to accelerate at all and no matter what I do the car will slow almost every warning light on the dash comes on and there are 11 different warnings I've uploaded photos of a few I have a video though also and you lose complete power and ability to drive warning lights such as power steering problem emissions problem powertrain problem all of those are part of what turns on if you try to move the vehicle it will not move unless it is an EV mode and even then it only works for several feet but you can't get over a few miles per hour if you are on the highway like I was going 65 mph and there's traffic is extremely dangerous the only reason I was not hit was because I turn my emergency lights on and was able to maneuver my vehicle to the shoulder safely had I been in a more busy section of the road or had I been in an area where I could not get off the road I would have been hit by another vehicle. Honda has stated they can't find anything wrong with the vehicle but a quick Google search shows that this is a common issue and I have a video of the dash with all the warning lights should anyone need it as well as photos.

The Body Control Module has gone out on my 2021 Honda Accord. Yesterday, when it went out, it affected ALL ADAS Features, in addition to key functionality of the car.

I turned my car on and it didn't want to crank up. Once it did crank up every warning light came on. My son ran the code and P00087 came up. I tried to drive my car in my parking lot and it kept stalling like it was going to cut off. Now I drove my car earlier in the day and didn't have any problems. It wasn't until after my car sat throughout the day when this took place. I know it's a recall for fuel pump issues but my car isn't included.

This problem is seemingly widespread from one google search! The infotainment system screen will randomly start doing “ghost touches,” tapping random areas of the screen which is distracting but also clicking on things that shouldn’t be casually clicked like emergency calling or calling a random number! The screen would end my navigation, mute the speaker, go back, switch to a different app, etc. There is no warning lights or anything. The honda dealerships seem to realize that this is a know issue but will not replace it. They stated that replacing it is doesn’t always work as the problem returns. My car is perfect besides this issue and has never been in a crash.

Car will drive fine , then all of a sudden it shuts completely OFF on the highway which is a MAJOR safety concern. ALL the lights will pop on in the dash board without any warning. Car will act as if it doesn’t want to pick up speed then after about 10-15 mins starts driving fine . This is my second time contacting you all regarding the same issues . Honda needs to definitely do a RECALL ASAP this is NOT SAFE at all to be driving around like this . ALOT of customers driving 2018-2022 Honda Accords have been having the same EXACT issues ..

The touch screen is malfunctioning. Its "ghost touching" as in the screen is pressing random buttons on the screen at random times while driving. It can change and has changed settings while driving (distance for breaking before a collision, etc). While its touching random things on the screen im unable to touch anything on the screen. As if its locking me from pressing anything.

While driving, all of my dashboard warning lights turn on at the same time. On several occasions, the vehicle has also completely shut off while I was driving, creating a dangerous situation where I lost power steering & braking assistance. I request that your safety/ recall department investigate this issue immediately to determine whether it falls under an active recall or should be added as a new recall. I know several people who has the same issue in my city with the same model car as mines. plus I seen on social media where people who has the model as mines have the same issue.

Blend door actuator is making a loud clicking noise which indicates the blend door actuator is either broken or going out. This problem will cause the heat and air to not function correctly. This seems to be an issue on several makes and models of Hondas 2019-2021(possibly other years). My Honda has 46,000 miles on and always had scheduled maintenance completed.

The infotainment system is registering multiple "ghost" touches, switching screens from GPS Air Play, to FM radio, to system info, to screen saver, to making actual phone calls, etc. This happens many times within a 30 second window. Many times, the infotainment system will power on its own accord and then flip through various screens. It has been reset 20-25 times and a hard reset by disconnecting a battery 5 times. Nothing helps. Honda said nothing they can do. I have multiple videos to prove the problem. This is a common problem as stated across multiple Honda Accord forums. It creates an unsafe driving environment.

Car won’t start, all lights on the dashboard are on and off and shows a message about brake problems and contact the dealership

The control panel/display touch screen stops working and the display acquires a mind of its own. It begins selecting things randomly and quickly. Automatically changing the radio, volume, and calling people in my contacts. Major distraction while driving and has almost caused accident for me multiple times

Infotainment screen is glitching. Randomly selecting options, turning on GPS, turning off GPS, changing the stations, and just selecting the different options on screen without actually having touched it with a finger.

Experienced CMBS with malfunctioning false breaking while no obstacle, acceleration delays (Features not available: Electric braking, lane departure, Electric power steering, Cruise control, Adaptive collusion prevention and brake system warning on dashboard).

my radio is acting crazy it change by it self and change screens

The contact owns a 2021 Honda Accord. The contact stated that while the vehicle was parked, the contact noticed the interior of the vehicle was full of smoke. The vehicle was unoccupied. The contact stated no visible fire was noticed. The contact inspected and noticed that the passenger side of the dashboard and the glove box were melted. The contact stated the vehicle had just been driven and parked for about an hour prior to the failure. No warning lights were illuminated. In addition, the passenger front door well and the carpet on the front passenger side were melted. The local fire department was contacted and determined that the fire was caused by exposed wires. The fire department chief disconnected the battery as a precaution. The vehicle was towed to the dealer. The vehicle was not diagnosed. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 100,000.

NOTE: the item / malfunction described below is CURRENTLY UNDER RECALL for multiple Honda models but has not YET been recalled for the 2021 Accord Sport 2.0T. Please add this model to the recall list!!! I had been driving on the interstate for about 30 minutes on Thursday, 11/7, when suddenly seven of the warning lights flashed in succession on my vehicle, including braking system warnings, emission system warnings, and tire pressure system warmings. I pulled to the side of the road, quite concerned. I called the dealership. The service professional thought it might be the radar on the front camera causing an electrical system malfunction. I was advised by the service technician to drive slowly (about 55mph) and come to the dealership (about an hour away). Upon inspection by the dealer, it was determined that the high-pressure fuel pump in the engine was defective. I did a bit of research: this is the SAME PART that is currently under recall for 720,000 vehicles (2023–2024 Honda Accord and Accord Hybrid, 2025 Honda Civic Sedan and Civic Sedan Hybrid, and 2023–2025 Honda CR-V Hybrid). Please add the Honda Accord Sport 2.0 T, 2019-2022 to the recall list for this issue!
