   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.

   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.

   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.

   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.

    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.

    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.
