| Jan 2026 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |

| Dec 2025 | ENGINE AND ENGINE COOLING | The contact's girlfriend owns a 2021 Honda Accord. The contact stated that while his girlfriend was driving at an undisclosed speed, the check engine warning light and several other unknown warning lights illuminated. Additionally, the contact stated that the engine was slightly misfiring while driving. An independent mechanic replaced the spark plugs and the ignition coils at the residence; however, the failure recurred 3 weeks later. The mechanic inspected the vehicle but could not determine the cause of the failure. The vehicle was taken to the dealer, where it was diagnosed with head gasket and fuel injector failure. The contact was provided an estimate for the repair. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 74,000. | Crash: No Fire: No | 74,000 |

| Nov 2025 | UNKNOWN OR OTHER | I am reporting a safety-related issue on my 2021 Honda Accord Hybrid involving a failure of the heating and climate control system. The vehicle is unable to produce heat or properly defrost the windshield, which significantly reduces visibility in cold weather. This directly impacts safe operation during winter conditions and should be considered a safety concern rather than a comfort issue. A Honda dealership diagnosed the problem as a heater core failure. The heater core itself is approximately 150, but the repair requires extensive disassembly and is estimated at nearly 2,000 due to labor. This type of failure should not occur on a vehicle this new. I recently purchased the car and do not believe this is normal wear or maintenance. Honda was contacted and denied goodwill assistance, stating they have no record of other complaints. I have since found similar reports from other Accord owners experiencing heating failures, particularly on hybrid models. This failure prevents windshield defogging and makes the vehicle unsafe for winter driving. I am documenting this issue with NHTSA so that the safety implications of heater failure on this model can be formally reviewed. I can provide the dealer diagnostic report, repair estimate, and Honda case number upon request. Vehicle Details: 2021 Honda Accord Hybrid EX VIN: [XXX] Mileage at failure: 47000 Date diagnosed: 11/13/25 Location: Salinas, CA Please advise if additional documentation is needed.

| Nov 2025 | UNKNOWN OR OTHER | The infotainment screen repeatedly overheats and runs through ghost commands (commands not initiated by the user). This includes repeated, unsolicitated phone calls, texts, radio changes, GPS commands, system tones, etc. This is dangerously distracting and takes the drivers attention off the road ahead.

| Oct 2025 | POWER TRAIN | The head gaskets are known to fail on the 10 generation accord. It failed on my 2021 Honda accord ex-l. I left work and while I was driving the dashboard lit up with every possible light. This was quickly followed by the vehicle losing power on the highway. I ultimately got it repaired by a Honda certified mechanic. The mechanic took it to a Honda dealer to confirm it was the gasket, in which it was. There were no warning lamps message or other symptoms prior to the failure. At the time of power loss I was on an 8 lane highway at 70mph. Luckily no accidents occurred, but the failure definitely put my safety at risk along with others. The mechanic I took my vehicle to has all available information if needed upon request. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE | I hereby state that my 2021 Honda Accord has experienced major mechanical failures involving the transmission and head gasket. The vehicle began exhibiting mechanical issues including rough shifting, loss of power, and engine overheating. Upon inspection by a qualified automotive technician, it was determined that both the transmission and head gasket have failed prematurely. These failures have rendered the vehicle unsafe and inoperable, resulting in significant repair costs, loss of use, and financial hardship. The nature and timing of these failures suggest a possible manufacturing or design defect. This statement is submitted in support of a formal claim and potential legal action against the responsible parties for the defective condition of the vehicle. | Crash: No Fire: No | Unknown |
| Oct 2025 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | I was driving northbound in on I15 in Salt Lake City when a Home Depot Bucket blew into my lane.

| Oct 2025 | ELECTRICAL SYSTEM | 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 .. | Crash: No Fire: No | Unknown |
| Oct 2025 | SERVICE BRAKES | What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle’s collision avoidance automatic braking system is malfunctioning. It engages unexpectedly while the vehicle is moving with normal traffic flow. The system is still installed and fully available for inspection upon request. How was your safety or the safety of others put at risk? The automatic braking system activates suddenly and without cause while I am driving at typical speeds (approximately 40–60 mph) with the flow of traffic. This unexpected braking creates a serious risk of rear-end collisions, both endangering me and putting other drivers at risk of crashing into my vehicle from behind. Has the problem been reproduced or confirmed by a dealer or independent service center? I have reported the issue to the dealer, but they have been unable to replicate the problem during their inspections. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? No, the vehicle and its braking system have not yet been inspected by the manufacturer, law enforcement, insurance representatives, or any other third parties. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights, messages, or other indicators were present before the issue occurred. I purchased the vehicle last month, and the problem with the collision avoidance braking system has been present consistently since then. | Crash: No Fire: No | Unknown |

| Oct 2025 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Sep 2025 | ENGINE | 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. | Crash: Yes Fire: No Injuries: 2 Towed | Unknown |
| Sep 2025 | UNKNOWN OR OTHER | I am writing to formally report a safety concern regarding the infotainment system in my 2021 Honda Accord. The infotainment system in my vehicle is faulty and exhibits consistent glitches that I believe pose a serious safety risk while operating the vehicle. The system frequently malfunctions by freezing, restarting unexpectedly, lagging during operation, or becoming entirely unresponsive. These issues affect critical functions such as navigation, backup camera display, audio controls, and in some cases, the touchscreen completely locks up, forcing me to divert my attention from the road. The system has even placed my iPhone into reset mode. This is not an isolated incident. The problem occurs on a regular basis and seems to worsen over time. I have attempted to address this issue with the dealership, but no permanent fix has been offered, and the system continues to behave erratically. This is highly distracting and potentially dangerous, especially when quick access to vehicle features is needed during driving. I believe this issue warrants investigation, as it undermines driver focus and could lead to an accident. I urge the NHTSA to look into this matter and consider whether a recall or manufacturer fix is necessary to ensure driver and passenger safety. Toyota is recalling 591,377 automobiles because the instrument panel display can fail and not show the driver critical information including vehicle speed, brake system and tire pressure warning lights, which could lead to a crash and injury. This issue has been going on for years with Honda vehicles but it's never been recalled. Vehicle details: Make/Model: 2021 Honda Accord VIN: [XXX] Mileage: 77,628 Date of Purchase: November 2021 Problem Frequency: Ongoing and frequent (daily ) I am happy to provide any additional documentation or video evidence if needed.

| Sep 2025 | UNKNOWN OR OTHER | My car ran hot for the first time and I was told my head gaskets were blown and I needed a new radiator. Once I got that repaired I was then told my transmission cooler went bad on my car which caused my engine to run hot and blow my gaskets in addition to cracking my radiator. I keep my car serviced as required with the Honda dealership and they had advised seeing this same issue in several other vehicles like mine. My car has less than 100k miles and I am the only owner. It has never given me ANY warning lights. The techs feel this is a manufacturer defect as my car should not be having this type of issue this soon. That’s the benefit of a Honda as I have owned several new Hondas and have never had any issues. I have done research and there are several forms with this same issue reported. I am attaching the initial work order. I was just advised of the transmission issue on Monday. | Crash: No Fire: No | Unknown |
| Sep 2025 | LANE DEPARTURE: ASSIST | This Honda continues to have fantom alerts and false warnings that triggers the car to jerk the steering wheel and try to steer you into another lane. I have narrowly avoided crashes more than 50 times. No "safety" system should be able to jerk the wheel out of your hands. You have know for more than 5 years about this defect, why no action? Shameful mismanagement that now needs to sued to get a reaction. | Crash: No Fire: No | Unknown |
