Honda Accord 2021 — Problemas relatados

In many Hondas, Toyota, Kia, Hyundai you name it they have this flaw. If it is dark out and headlights are needed but they have bright running lights people will be driving around without taillights and the cars won't say a thing, I think headlamps suggested messages should appear on their dash so they know they have to turn them on or auto headlights that can't be disabled should be mandated on all new cars

I am submitting this complaint regarding an ongoing safety concern with my 2021 Honda Accord. Multiple lights indicate engine system problems which includes, check engine light, car jerks at acceleration, seat sensor recall. I took my vehicle to multiple shops including the Honda Dealership. However, they were unsuccessful to identify the cause. Multiple problems such as Turbo, belt, fuel system problem constantly comes up. I have attempted to take my vehicle for the recall, which was scheduled, however after waiting 4hrs, the dealership stated they did not have the parts. I am concerned about the potential risk to myself, my daughter and my passengers and believe these issues warrant further investigation to help prevent possible accident or injury.

Vehicle: 2021 Honda Accord Sport Subject: Intermittent Electrical Malfunctions, Multiple Safety Warnings, and Loss of Acceleration I am reporting ongoing safety concerns involving my 2021 Honda Accord Sport. On multiple occasions, my vehicle has displayed several dashboard warnings, including brake system, electric parking brake, vehicle stability assist, hill-start assist, adaptive cruise control, and electric power steering warnings. These warnings have appeared intermittently in the past and sometimes disappeared on their own. On October 18, 2026, while traveling on the highway at approximately 65 mph, these warnings had already been displayed for approximately 30 minutes to an hour when my vehicle suddenly began struggling to accelerate. Despite pressing the accelerator, the vehicle continued losing speed, and the RPM gauge remained around 2,000 RPM. It felt as though something was holding the vehicle back. After several moments, the vehicle suddenly regained power, accelerated, and the RPM increased. This was particularly concerning because I was traveling at highway speed. I also experienced electrical problems with the interior lights. While the vehicle was running, neither the automatic interior lights nor the overhead lights near the rearview mirror would turn on. They remained inoperative after I turned off the vehicle. Later, the lights began working again, but I noticed the right overhead light fading while the left remained illuminated. The battery was replaced earlier this year, in 2026. I am concerned that these intermittent malfunctions could result in a sudden loss of power or failure of important vehicle safety systems while driving. I am requesting that these problems be documented and investigated for a potential safety defect or recall. I have photographs of the dashboard warnings available as supporting documentation.

Electrical problems that causes damages to the engine and problems with acceleration.

Infotainment System glitching: "ghost touch"; the screen is not registering my touches and randomly selecting/pushing buttons all on its own. Took it to Honda dealership and they have no answer or fix. This happens from time to time while driving, causing a huge safety concern. Extremely distracting to me, the driver. Everywhere I go to get answers, I only get "issue is known to manufacturer but no fix available; they are currently working on a fix". This has happened multiple times intermittently since I've purchased the vehicle in 2021.

The contact owns a 2021 Honda Accord. The contact stated that while his wife was driving at 65 MPH, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended. The vehicle hesitated and then accelerated; however, the vehicle then failed to accelerate above 20 MPH. Several unknown warning lights illuminated. The contact's wife drove the vehicle to a safe location and parked. While attempting to start the vehicle, the engine started and then shut off. The dealer was notified of the failure, and the vehicle was towed to the dealer, where it was diagnosed with a fuel pump failure requiring fuel pump replacement. The contact referenced a recall with a similar failure description; however, the contact's VIN was not included. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 152,100.

I bought my Accord in February of 2026 with only 79k miles (now at 93k). 3 days after purchasing all of these warning lights popped up regarding emissions, brake system, power steering, etc. I brought it back in and they said that it needed a new fuel injector on cylinder one (which didn’t fix the issue). I have replaced all 4 spark plugs and kept up with maintenance since it has been in my ownership. Now I’m having issues with the car going in limp mode, decreased acceleration, decreased mpg, and constant misfire codes! I do not feel safe in this car anymore since it has almost left me stranded as well as it disabling the safety features which could put me at risk. Honda desperately needs to fix this issue seeing as it’s putting their customers at risk, along with others on the road. NHTSA please do something!

Was at a stoplight, came to a complete stop once at a complete stop car completely shut all the way off, losing all electricity no hazard lights. You cannot press down on the brakes to restart the car. You could not do anything. Car lost 100% of power 5 to 10 minutes later, Vehicle shut back on automatically and engine started to run automatically.

head unit touch screen will occasionally, uncontrollably create multiple phantom touches all over the screen, multiple per second continuously. driver cannot resolve while in motion. driver cannot cannot click away while the issue is occurring as the issue seems to mask real input. very distracting not only visually, but hearing as well. worst case the car could inadvertently contact emergency services via phones or cars sos capabilities. occurs at any / all speeds. multiple reported issues online and honda has done nothing.

Vehicle infotaiment screen glitches and therefore is not making user access all car warnings ans switches screen during driving specially if using the navigation feature.

The infotainment center went bad. It has been replaced... twice and is still bad. The screen jumps from XM radio to compass to clock to settings to FM radio to maps to XM radio to _____. It may do that 30-40 times a minute. And with each change there is a beep. This cannot be turned off. It is verrrry distracting. Honda says there is nothing that can be done to fix this. ?!?!?!?! They said I would have to wait until they come up with an idea to try, though it may be a year to two. Going online reveals that many others have the same issue. This cannot be safe. Beep..... beep.... beep.... beep. Ans the screen changing. You are constantly trying to touch the screen to get it back there you want it. It may takes 50-60 touches to do it. All the time you are trying to watch the road. CAN YOU PLEASE HELP???

My 2021 Honda Accord Touring 2.0T has an intermittent touchscreen/infotainment malfunction commonly described as “ghost touch” or “phantom touch.” The touchscreen generates inputs on its own without the screen being touched, causing menus and functions to change unexpectedly while the vehicle is being driven. The malfunction is distracting because the infotainment system begins operating by itself and requires driver attention to correct or stop the unwanted inputs. The same center display is also used for vehicle information and the rear-view camera, which makes reliability of the display a safety concern. Honda Corporate has been contacted regarding the problem. I have been advised that Honda is aware of the issue but is not currently authorizing a repair because a permanent repair/fix has not yet been developed or released. I have an extended warranty that can cover a repair, but Honda has not provided an approved permanent repair at this time. The problem is intermittent and may occur unpredictably. The factory touchscreen remains installed and the vehicle is available for inspection. I am submitting this complaint because the defect can create significant driver distraction and affects a display that is integrated with important vehicle functions.

The contact owns a 2021 Honda Accord. The contact stated that while driving with the driver assist enabled, the vehicle veered over to the left and crashed into the median. The contact stated that the vehicle was uncontrollable. No air bags deployed. The vehicle was towed to a local tow yard. A Police report was filed; however, the information was unavailable. The contact was transported to the local medical center. The contact sustained bruises and pain to the body. The manufacturer was contacted by phone, and a case was filed.

Active Turbocharger Boost Control Position Sensor "A" Circuit Range/Performance 0x00

The infotainment/touchscreen system in my 2021 Honda Accord is malfunctioning and experiencing what is commonly referred to as “ghost touching.” This issue has been occurring since approximately March 2026. While I am driving, the touchscreen will randomly make selections on its own without me touching the screen. This is especially concerning when I am using GPS/navigation because the system can change screens, select different options, and interfere with the navigation information I am trying to view while driving. This creates a safety concern because the unexpected touchscreen activity is distracting and causes me to take my attention away from the road to correct what the system is doing. The issue happens without warning and can occur while the vehicle is moving and I am relying on GPS for directions. I took the vehicle to a Honda dealership regarding the problem. The dealership was made aware of the ghost-touch issue and stated that there is currently no fix available for it. The touchscreen and related components are still installed in the vehicle and are available for inspection upon request. The vehicle has not been inspected for this issue by police, insurance representatives, or any other outside party. There are no warning lights or dashboard warning messages before the malfunction occurs. The primary symptom is the touchscreen suddenly registering inputs and making selections on its own even though I am not touching it. The problem first began around March 2026 and has continued intermittently since then, including while driving and actively using GPS/navigation.

The contact owns a 2021 Honda Accord. The contact stated that while her son was driving 55 MPH, the vehicle shut off with several warning lights illuminated on the instrument panel. The contact's son pulled off to the shoulder of the highway and had the vehicle towed to a dealer. While at the dealer, the mechanic discovered coolant leaking into cylinder #2, causing an engine misfire. The dealer replaced the head gasket. After the repair, the failure returned immediately upon driving the vehicle home from the dealer. The vehicle was taken back to the dealer and the failure persisted upon return of the vehicle. While checking the repair order, the contact discovered that the service report was blank. The dealer was unable to duplicate the failure or determine the cause of the issue. The contact was not notified of the issue after retrieving the vehicle. The manufacturer was notified of the failure, and the contact was provided a case number. The vehicle remained with the dealer unrepaired. The failure mileage was 43,881.

Sudden braking; car comes to a complete stop and brakes so Hard. Most likely fault from Collision Mitigation Brakking system

COMPONENT: Visibility--Exterior Rearview Mirror, Passenger Side. While driving normally, the passenger-side exterior rearview mirror glass/holder assembly suddenly shattered and completely detached from the mirror housing. There had been no known collision or contact with another vehicle or object. The passenger window was open. The detached mirror glass/holder assembly entered through the open passenger window and landed on the passenger seat. Numerous small fragments of mirror glass were also deposited inside the passenger compartment, including on the passenger seat and dashboard. After the incident, the passenger-side mirror housing remained attached to the vehicle and remained in its normal extended operating position. The housing did not fold from the event and does not exhibit obvious significant collision damage. The detached mirror assembly and photographs have been preserved. Photographs show the exterior mirror housing,m the exposed internal adjustment mechanism, the shattered mirror assembly on the passenger seat, the shattered glass and the rear of the detached mirror holder/adjustment assembly. I am concerned that this may represent a failure of the mirror glass/holder or its attachment mechanism rather than ordinary collision damage. Because the mirror assembly and glass fragments entered the occupied passenger compartment, I believe the event presents a potential safety hazard to vehicle occupants. I am requesting that NHTSA retain this complaint for comparison with similar reports involving Honda Accord exterior mirror glass shattering or detachment.

The car's infotainment system constantly glitches out and changes channels,outputs,texts,videos while car is being driven. It's very distracting and dangerous. It will literally do it 100's of times within a short period. It's much worse than any text messaging distraction, which is against the law. Several people with this car have the same issue. Also the car will break when there's actually nothing in the road that should make it break but it will just slam on the brakes.

Vehicle started flashing all lights on dashboard. I drove it for awhile and then it eventually went off. A few days later same lights came back on a car started misfiring. Was told by Honda that is was the Turbo that's going bad. Today is just cut off on me. Luckily there wasn't anyone behind me. I see a lot of people are having these same issues and a recall should be put out immediately.

Door lock actuator(s) randomly failing to lock/unlock. Multiple reports on forums for same exact issue. Replace one, another fails shortly after. Issue involves both locking and unlocking, putting safety individuals at risk for unexpected access to car or inability to lock car once inside. No messages, warnings, or suggestions from car to tell me that the locking had failed.

Unable to use cruise control Unable to use lane control Unable to use tire pressure gauge Unable to use auto brake system Car shakes due to a sudden decrease in engine performance. Turbocharger issues Powertrain System issues ECM Failure

Dash lights on for Brake system malfunction. Emergency parking brake light on as well as TPS system. Lights around Park, Neutral and drive not illuminated. Battery and alternator are in good standing.

All of my services lights are on in th dashboard.

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.

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!

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.

Emission system

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.

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 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,

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

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.

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

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

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.

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.

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.

Infotainment Center

My infotainment system is not working properly. It switches between screens, radio stations, etc., and sometimes turns off. It is very dangerous when I am driving using my map and the map either moves, stops working, or switches to a different screen. I have had to pull over in the middle of nowhere while traveling because the map quit working properly. It also cuts me off in the middle of phone conversations. I just put a random date below because this has been going on for almost a year now.

The vehicle suffered an unexpected loss of engine compression and dropped into a dangerous Limp Mode while driving due to a Cylinder 3 Misfire code (P0303). The manufacturer dealership misdiagnosed the mechanical issue using an unrelated 2.0L engine service bulletin (SB23-026) to clear the error. Six months later, the dashboard completely illuminated again with code P0299 (Turbocharger Underboost) caused by progressive pressure and compression loss across the 1.5L turbo engineering components. Upon post-visit inspection, engine fluids were found severely depleted. This ongoing engineering failure causes a sudden loss of vehicle motive power on public highways, creating a severe, recurring safety hazard that mirrors the active federal engine defect class-action litigation against American Honda Motor Co. This has happened 4 times with all the lights on my dash coming on Dec 2025, May 2026, June 2026 (2x)

The contact owns a 2021 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle decelerated and was hesitating while accelerating. The vehicle was taken to the dealer, where the spark plugs were replaced. The contact stated that months later, the vehicle experienced the same issue and was taken back to the dealer, where it was diagnosed with a blown head gasket. Two months later, the spark plugs were replaced again. Another two months later, additional components were repaired. The vehicle had been at the dealer for several months and the technicians were unable to determine the cause of the failure. The low engine oil warning light was illuminated, even though the engine oil level was not low. The dealer was unaware of the cause of the failure and stated that the engine needed to be dissembled for further inspection. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 133,000.

The contact owns a 2021 Honda Accord. The contact stated that while driving at an undisclosed speed, the navigation system independently switched to random screens and made random phone calls. In addition, the contact stated that the failure had occurred while the GPS was activated. The dealer was made aware of the failure. The contact was recommended to take the vehicle for a diagnostic test. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 72,693.

While driving to work, the radio seem to have a ghost inside the radio. The screen has a mind of its on. The radio turns itself off and on by itself. It’s a safe hazard to driving with all that is happening. The radio will beep constantly while driving down the road and my teenager will not driving my car, due to being scared

I have been experiencing what’s being called “ghost touches” on google. This is a known issue that needs to be addressed. Also VIN number starting with 1HGCV need to be added to the fuel pump recall list. I’ve had to change both systems.
