2021 HONDA ACCORD Electrical System Problems

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 ..

infotainment system glitching

Radio/ car play jumping screens cuts in and out just randomly. Sometimes goes completely black screen

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.

This vehicles have a engineering flaw in the design of the head gasket failing prematurely disabling all components of vehicle at any given time wether it’s in the highway or local the car will basically shut itself down causing a major risk for the driver and civilians even death. This is a safety hazard, tragedy waiting to happen y’all should act now theirs multiple and quiet frankly the Corporation should be taking care of it since they are still allowing them out on the road even with knowledge of this issue the customer should not loose their life nor money to a mass production engineering flaw that’s is over seen by NHTSA, HONDA. I got in to an accident due to my vehicle not being at 100% because of the head gasket issue the cars availability to detect or use its components, mechanically or electrical.

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 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.

I have experienced persistent and frustrating issues with the infotainment system of my 2021 Honda Accord Touring. These problems affect both the usability and reliability of critical in-car technology, impacting daily driving and reduces overall satisfaction. Specifically: 1. Touchscreen Malfunctions Symptoms: Unresponsive screens, freezing, and “ghost touches” (inputs registered without physical contact) disrupt navigation, audio, and other controls 2. System Crashes and Reboots Symptoms: The system may randomly crash, freeze, or restart, sometimes causing the entire dashboard to shut off—even while driving 3. Connectivity Problems Symptoms: Frequent disconnections or failures with Apple CarPlay, Android Auto, and Bluetooth, making it hard to use smartphone features safely 4. Blank or Malfunctioning Displays Symptoms: The screen may go black, fail to turn on, or show a white screen, obscuring navigation, fuel, and safety information 5. Battery Drain Symptoms: The infotainment system sometimes powers on unexpectedly when the car is off, draining the battery and risking further electrical issues. These issues are not new and have attempted to be resolved by a Honda Service Center (Honda of Westport, CT) with no resolution or ability to resolve.

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.

The contact owns a 2021 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle started jerking. Several unknown warning lights were illuminated. The contact stated that some time after the incident, the vehicle was involved in a crash due to the vehicle jerking and all the lights illuminating on the instrument panel, resulting in damage to the front bumper. The vehicle was taken to a local dealer, where it was diagnosed that the turbocharger needed to be replaced due to a missing screw. The dealer advised the contact to contact a local independent mechanic for assistance, who performed a repair before the crash. The vehicle was taken to the independent mechanic, where it was diagnosed with a loose battery. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 69,000.

Mileage: 69,000

Information console glitches randomly and will close out maps, play music, switch input sources, and will call/hangup without driver input. Initially happened maybe 1-2 times a month, however now happens constantly making the entire informatics system inoperable and is very distracting. I am unable to upload the videos of it glitching (this doesn’t allow video files) but can provide if needed

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

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

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

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!

Touch screen glitching and beeping, acts as if being touched and scrolls through settings and apps randomly; makes phone calls that can’t easily be disconnected, hangs up calls, enables or disables navigation. Many distracting and potentially dangerous glitches. Unsure if integrates into automated features and unsure if it will engage braking, steering, cruise control, etc. while driving. Replacement part indefinitely back ordered. Local and corporate uncooperative in answering questions regarding safety concerns. Touchscreen unresponsive frequently.

The infotainment system randomly presses all over the screen all the time. This causes tony of issues such as turning on the radio, changing navigation, and making beeping noises constantly. Honda has replaced the infotainment system twice in my vehicle and it has fixed absolutely nothing. This is a major safety issue because of how distracting it is when driving. The incessant beeping noises (it beeps every time the touch screen is “pressed”) makes it so that I don’t know whether the car is beeping for safety issues (lane assist etc) or not. The radio being turned on at random is extremely startling and has caused me many near accidents. The navigation turning off as I am navigating through traffic has caused much stress and confusion which can lead to an accident. This is a major issue that needs correction ASAP.

As I parked my vehicle all of the dashboard lights turned on simultaneously. My safety is at risk because I can not identify or predict the safety of my vehicle. I have not visited my dealer at this point. I have had a check engine light that would come on and would go away. I’d be told by mechanics that it is a computer issue. My last encounter with this was approximately 2-3 months ago.

I have only had this car 4 months, if that long. I have put very few miles on it. Driving home from work, at most 35 mph, there was a loud thud from what seemed the floorboard followed by a sharp slam of the brakes that i could not control. Many of the instrument warning lights came on. some flashed, some stayed on. I was able to pull onto the shoulder of the road to call for help. However, upon trying to put the car into gear again, it would not move. This is very very disappointing as it was purchased at not only an expensive price, but bought with a promise of your Honda dealership. It is noteworthy that i had just returned home from a trip a day or two prior to this happening. Had this happened unexpectantly in six lanes of traffic, it would have certainly caused an accident or worse. After doing some research, I see there were many defects specific to the make and model of this car. I was never informed of any of them. Please see CVT control information published for reference. I have spoken with the dealership multiple times and I have been unable to come to any resolution concerning this new vehicle, that is unable to be driven. Scary and Dangerous!

Brakes failed and steering took over the car uncontrollably and went in all different directions hitting whatever it came across and ending up stopping after hitting the last thing

I was driving home in the rain and felt the car automatically braking when there was no car or object in front of me. The car was also slow to accelerate because the brakes were automatically applied. 5 miles later numerous warnings appeared on the dash and the following error messages came through my Hondalink app: Electric Parking Brake Problem, CMBS Problem, Adaptive Cruise Control Problem, and RDM Problem. Several times during this drive home the brakes automatically applied without any intervention from me or roadway object. I almost got rear-ended once when a car behind me had to slam on its brake when my car automatically braked without me doing anything. This is a very dangerous condition that should be looked further into as multiple drivers have reported brakes being applied without driver intervention or an apparent road hazard. How many complaints will it take before a recall is issued so other Honda drivers do not need to be put at risk?

Hello, i want to report an issue with my honda accord 2.0t 2021. When i drive in rainy or snowy day all lights come up on dashboard and probably 70% of the futures gets disabled. Things that gets disabled: Back up camera, line assistant, trunk doesn’t open, A/C doesn’t work, windshield wipers spray doesn’t work, high beam doesn’t work, horn gets stuck and beeps and the only way to shut off is to stop and disconnect the battery, otherwise it beeps non stop. I record a video and here is the link. Thank you https://youtu.be/ABoYlunVNVo

Hello, the car has this issue since i got it nrand new. Every time i drive in the rain or while its snowing, all lights on the dash board comes up and at least 50% of the options gets disabled. Like back up camera, windshield vipers, horn beeps non stop until you disconnect the battery and more. I see there is lots of people reporting same issue but honda dont want to help me with this issue. Went to homda dealer and they said $169 for diagnostics, then called and said its gonna be 2 hours which is $338 and even then saying they are not sure if it will take them 2hrs or 10 and i had no choice to tell them to stop and pay only $169.

I was driving my 21 Honda Accord 1.5T on the highway and all of a sudden vehicle lost the power and Honda sensing / Emission warning lights came on. It almost cause a major accident and I was lucky enough to exit the freeway without incident. I drove to the Honda dealer and they found out one of the wire harnesses was chewed by a rodent which causes the whole issue. I did some research and found out that Honda was using less expensive Soybean base wire harnesses (instead of Petroleum base wire harnesses) to save the planet earth. This Soybean wires are easy target for rodents. This less expensive Soybean wire harness cost about $3000-3500 to replace and it's NOT fair to the consumer. Honda must re-call this Soybean wire harness before causing some major accident, especially on the freeway ( imaging your car losing power while driving 65-70 mph)

I was with my family taking the on ramp to the Long Island expressway, when suddenly the rear wheels locked up and the parking brake was engaged. I hit the brakes. And as fast as it happened is as fast as it resolved. Scared all of us and almost got hit from the car behind us.

Automatic braking has initiated for no reason, at least four times almost causing accidents, car radio sometimes will no shut off, seems to be some type of electrical problem, I have had both issues looked at by dealer who states they cannot find a problem with this vehicle, there is Definitely a problem and it must be found before someone get hurt. auto braking has happened on the freeway, and on residential streets
