SUBJECT: A REQUEST FOR HONDA CORPORATE INVESTIGATION AND GOODWILL ASSISTANCE - 2021 HONDA ACCORD I am submitting a formal complaint regarding serious and recurring electrical and safety-related problems with my 2021 Honda Accord. 1. Numerous dashboard warning lights and safety-system warnings illuminate simultaneously. 2. The vehicle repeatedly displays messages instructing me to "See Dealer." 3. The power door locks repeatedly click and cycle as though they are attempting to lock or unlock on their own. 4. The stereo, on its own, scrolls through buttons and bluetooth blinking through all the stereo options on its own. 5.An OBD diagnostic code reader is unable to properly communicate with the vehicle and reports "Unable to Connect/Vehicle Not Found." 6. Sudden brake activated without any object being in front of the vehicle. 7. Factory Rims Extensive finish failure The simultaneous occurrence of these problems strongly suggest that this may involve an electrical, communication-network, body control module, wiring, power-supply, or other vehicle system defect rather than ordinary wear and tear. I am particularly concerned because the dashboard warnings involve vehicle systems that may affect braking, steering, stability control, driver-assistance features, and other safety functions. When numerous safety warnings illuminate at the same time, I have no reliable way of knowing which vehicle systems are actually functioning correctly. The repeated activation of the door-lock system is also concerning. The locks should not continuously activate on their own during normal vehicle operation. Combined with the diagnostic communication failure and multiple warning messages, this raises concern regarding a larger electrical or vehicle-network malfunction. Although the vehicle is currently outside the factory warranty period, this type of widespread electrical and safety malfunction should not reasonably occur in a 2021 vehicle as the result of normal use.

The contact owns a 2021 Honda Accord. The contact stated that while driving approximately 30 MPH, the message "Emission System Problem" was displayed. The vehicle was taken to the dealer, where it was diagnosed and determined that the turbocharger had failed and needed to be replaced. The contact was informed that the failure was a common issue. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 108,579.

My car currently has displayed all lights on panel. Went to auto zone to have codes read, shows powertrain-description is code PO299 suggests turbocharger assembly. Safety is put at risk because all of the safety features are now disabled.

Infotainment system recieving phantom / ghost touches. Screen selects menu items on its own, plays, pauses music, causes major distraction and disruption. Screen flashes when changing menus and can pull attention from the road. Safety issue!

40,000 miles and 5 years after original in service date - failure of 2021 ACCORD 1.5T headgasket system between cylinder s #1-2. Required full head disassembly, removal, rebuild of head, and replacement of head gasket and associated components. $6000 quote from Honda Corporate as I was 55 DAYS outside of warranty. Absolutely ridiculous for a 5 year old car with low miles.

Emission system

I own a 2021 Honda Accord Hybrid. Shortly after purchasing the vehicle as a used vehicle in 2023, I began experiencing intermittent air conditioning performance. The A/C would gradually lose cooling capacity over time until it was no longer able to cool the cabin effectively. To temporarily restore operation, I added refrigerant approximately twice per year, believing the system had developed a minor leak. As the condition worsened, I brought the vehicle to an authorized Honda dealership for diagnosis. The dealer diagnosed the vehicle with a leaking A/C condenser and a leaking heat exchanger pipe and recommended replacement of both components. Honda declined goodwill assistance because the vehicle is outside the original warranty period. I later learned that Honda previously issued an extended warranty for A/C condenser failures on 2018–2020 Accord models due to a known condenser defect. My vehicle exhibits the same symptoms of gradual refrigerant loss and declining cooling performance, despite being a 2021 model year. In researching this issue, I found multiple reports from other 2021 Accord and 2021 Accord Hybrid owners describing similar A/C condenser failures and refrigerant leaks. I am submitting this complaint because I believe there may be a broader pattern affecting 2021 Accord vehicles that warrants review. I am requesting that NHTSA document this complaint and evaluate whether similar failures are occurring in 2021 Honda Accord and Accord Hybrid vehicles.

My car stalled stopped and takes a While to turn on , all lights turned on .. coded came back and showed it was fuel pressure regulator / fuel pump. I believe it is part of the recalls put in place for other Honda accord lx as well since I’m having same problem

My center screen has a ghost touch; I have brought it to my dealer since the day I bought it I have been having screen and CarPlay issues. never fixed always told its fake phone cable, even though my phone can be disconnected and the screen still goes crazy, either way I left it alone because I can't keep going to the dealer, today while I was backing up this ghost touch keep changing my camera angle and caused the screen to freeze completely, I would suggest looking into this as I found many people online with the same issue,

The infotainment touchscreen in my 2021 Honda Accord Hybrid intermittently registers inputs that I am not making. The screen experiences repeated “ghost touches,” accompanied by random beeping and clicking sounds. During these episodes, the system changes GPS screens or navigation directions, changes music or audio settings, turns the audio on or off, closes applications, and opens other applications without any input from the driver. During these "ghost" episodes, the touch capability seems to also be intermittent preventing from leaving the current screen or app that the "ghost" clicks on. This problem occurs while the vehicle is being driven and creates a serious distraction. The unexpected sounds, screen changes, and navigation changes draw the driver’s attention away from the road and may require the driver to attempt to stop or correct the malfunctioning system. This increases the risk of a collision and could result in serious injury or death. I contacted a Honda dealership regarding the issue. The dealership indicated that it was aware of this behavior and had received similar reports from multiple other vehicle owners. The malfunction is intermittent, but it has occurred repeatedly. There were no warning lamps or dashboard warning messages before the touchscreen began malfunctioning. The vehicle and infotainment system are available for inspection upon request. I also have video evidence showing an example of the touchscreen malfunctioning and producing inputs without being touched.

My 2021 Honda Accord Sport has had a problem that started about 30k miles which I told them about 3 times. The sun visors do not stay up. they hang down and you have to move them out of the way. I tried to get the dealer to replace them, but they said I was past the warranty, and I was going to be changed about 400.00 per visor. I kept messing with them and finally it got a little better. But did not last. I told them again, but I could not, and would not spend over 800.00 for sun visors. Id do without them before paying 800.00! Used to they were simple made and no problems. But now they have mechanisms inside that have parts that wear out. Because Honda would not replace them, and Bell Honda would not either, I will not buy another care from Bell Honda. As when I bout my 2014 Nissan in [XXX], then moved to [XXX] I took my car to Nissan on Bell, and for the first time ever, before the Honda did it, a sun visor stopped functioning right in my Altima, but because I took my car there for services, the dealership replaced it for me. Now today, searching for new visors, I found that many people are having problems with the Honda visors, and saying it is a safety issues, and one person said their dealer replaced theirs 2 times. With all the complaints you'd think Honda would have to change the way they are made. But seems they don't care. In-fact, before my car had 40k miles, one of my motor mounts went out, and something else before that. Thankfully my motor warranty was still good. But these expansive, poorly made sun visors really should be recalled as it is a safety issue. Please do something to make that happen. Thank you! This is reoccurring from 2023-2026.

First of all started with small coolant missing, later on I started noticing power loss and finally white smoke out the exhaust. Blown Head Gasket. Honda need to own up on defect engine design the ford did awhile back. Those slits between the cylinder was a big mistake. I myself is doing the repair. 2021 Honda Accord Sport 2.0 with mods and tuned

I am submitting this complaint regarding my 2021 Honda Accord because of a serious safety issue involving the turbocharger and fuel injector system. While driving on the highway, my vehicle experienced a failure related to the turbocharger and fuel injector system, which caused multiple warning sensors to activate and resulted in the vehicle suddenly losing power and becoming unable to continue driving. This unexpected failure forced my car to stop in the middle of the highway, placing me and other motorists at significant risk of a serious accident or fatality. A vehicle should not suddenly become inoperable while traveling at highway speeds due to a mechanical defect. This creates an extremely dangerous situation, especially in heavy traffic where other drivers may not have sufficient time to react. After researching this issue, I discovered that numerous other owners of 2021 Honda Accords have reported similar failures involving the fuel injectors and turbocharger. Given the number of reported incidents and the serious safety risks associated with these failures, I believe this represents a potential defect that warrants investigation. I respectfully request that the National Highway Traffic Safety Administration investigate this issue and require Honda to issue a safety recall if appropriate. No driver should have to experience a sudden loss of power that leaves them stranded in moving traffic due to an apparent vehicle defect.

Had to repleace the electrical parking brake sensor. Now all my lights on the dash board are lighted up and have to go get a diagnostic test done

Touchscreen system in my 2021 Honda Accord Hybrid Touring is now having issues registering touches or is exhibiting ghost touches. This results in unpredictable selections for diverse systems like sound, touch free phone integration, navigation, etc. These are distracting in the extreme, and seem to be common during the afternoon hours in strong sun. This issue is partially mitigated via a hard reset, but this is helping less and less as this error becomes more and more common.

I’m not sure what it’s called, but the entertainment system where the touch screen is for radio, has ghost touches when the weather gets warm. Over the winter, this never happens. But during the summer, the screen starts glitching out and if I have gps going, this is a real safety issue because the ghost touches change the screen and I don’t know where I’m going. And it’s very distracting , the ghost touches continue every couple seconds.

On July 4th 2026, I was leaving from a restaurant that evening and within 5-10 seconds of me turning my car on, all of the lights on my dashboard turned on. I was slightly confused because there were multiple at once and my car was rumbling a bit from under the engine hood. Within a few weeks prior, I’ve been having with my digital car screen switching back and forth between tabs (from the radio, to my CarPlay, to the settings). It will be intermittent but fairly consistent. I plan to take my car to an auto parts store for a code test and battery/alternator test to see if there’s any further issues. I just purchased a new battery for this car within the 3 years of me getting it, 2 years ago and there shouldn’t be any issues. I’m not sure how to proceed and I really don’t have it in me to spend large amounts of money and time with repairs for a supposedly heavily reliable car. My current mileage is at 120,000.
