Head gasket issue please fix this problem for the customers
4 out of 5 times driving the car the infotainment screen with get random touches guiding you to unknown menus or system setting or maybe just to a different radio station. Where I think this becomes a legitimate safety concern (asside from changing vehicle settings like security) is when trying to use maps function the random touches will direct the map away from where you are or where your next turn might be. So you basically need to keep hitting re-center just to get you back on course. However most of the time there is an uncomanded touch that is stuck on the screen or possibly a number of touches that prevent a real finger print touch to be sensed ultimately preventing you from re-centering. This causes extended moments where attention is taken away from the road or late/last minute route correction causing unsafe road/driving conditions. The manufacturer only recommends doing a system restart of your infotainment screen which does nothing or complete replacement of the screen which in many cases including my own is not covered by warranty.... the alternative is to disconnect your phone from android auto or apple car play and use it in your hand which again causes distracted driving. If this was something as simple as a volume knob or temperature control not responding I wouldn't even be here but since it always touching different placed and navigating you places you dont want to be i see it as a clear safety issue that should be corrected. Thanks
Driving on the highway, my dashboard lit up like a Christmas tree. Car started having white smoke at tail pipe. Check engine lit blink 5 times. Had 4 kids under 14 years old in car. Almost got hit trying to merge over. Turns out misfire cylinder 4. Head gasket. Only 81,000 miles. I have owed 5 months. Car currently at Honda, they want almost 4,400 to repair. But apparently, Honda is aware of these HEAD gaskets going prematurely, in 1.5 l. and has done nothing about it. I do not have the money to repair this car on top of how dangerous it was to be driving on the highway.When this happened.
The lights and warnings below popped up on my dash after the engine light had come on and then off again for about a week. See below, -Emission system problem Avoid heavy acceleration and high speed. See dealer -tpms light -brake system problem -brake hold system problem -electric power steering system problem -vehicle stability assist system problem -hill start assist problem -adaptive cruise control system problem -collision mitigation braking system problem -road departure mitigation system problem Went to get diagnosed at the dealership and was told that the turbo on my engine had failed. Mechanic said it had nothing to do with me and that it failed on its own. I saw that it was a reoccurring problem with other Honda owners with the same year, make, and model as mine but are being given the run around and no solution.
ssue: Water intrusion into tail light assembly causing electrical and safety system malfunctions Status: Repaired at owner expense (~$800) Concern: Safety‑related defect and potential pattern across vehicles Description of the Issue: My 2021 Honda Accord experienced a failure where water entered the tail light assembly and caused electrical shorts. This resulted in multiple safety‑critical system warnings, including brake system alerts, ABS/VSA warnings, and Honda Sensing failures. The vehicle also lost acceleration and entered a reduced‑power “limp mode,” creating a hazardous driving situation. The dealership diagnosed the issue as water intrusion into the tail light assembly. The entire assembly had to be replaced at a cost of over $800. After replacement, all warnings and drivability issues resolved immediately.
Fuel pressure dropped and car stalled
The USB port in the center console of my 2022 Honda Accord (VIN: [XXX] ) is physically loose and wobbly, causing intermittent disconnection of Apple CarPlay. The vehicle is available for inspection upon request. When CarPlay disconnects while driving, I lose access to my navigation (GPS), requiring me to manually interact with my phone or the infotainment screen to restore the connection. This creates a significant distracted driving hazard. The disconnection occurs unpredictably with minor road vibrations or bumps, meaning it frequently happens at highway speeds. Not yet. The vehicle has not yet been brought in for this specific issue. The problem is consistently reproducible — any slight movement of the USB cable causes disconnection. This is a known and widely reported issue No. The vehicle has not yet been inspected by any of these parties regarding this specific defect. No warning lamps illuminate. The only symptom is the CarPlay interface disconnecting on the screen when the vehicle hits a bump or the cable is slightly moved, indicating the USB port itself is physically loose and failing to maintain a stable connection. The issue began and has persisted since I first noticed it. No prior warning was given before the port became loose. The USB port used for wired Apple CarPlay is physically loose and wobbly, causing the connection to drop with the slightest vibration or road bump. I have tried multiple cables and positions without improvement. Losing CarPlay while driving means losing active navigation, forcing dangerous driver distraction to reconnect. This is a known defect reported by numerous 2021 Accord owners. I am requesting this be investigated for a potential recall or technical service bulletin.

This has been reported one time before but the situation has gotten worse when driving at approximately 60ish miles per hour but it starts doing it about between 50 and 70 mph when driving and the car is using the regular engine not the EV section. You will randomly lose the ability to accelerate and you have to remove your foot from the gas let the engine slow and then re-accelerate now for the second time as I'm driving I lose the ability to accelerate at all and no matter what I do the car will slow almost every warning light on the dash comes on and there are 11 different warnings I've uploaded photos of a few I have a video though also and you lose complete power and ability to drive warning lights such as power steering problem emissions problem powertrain problem all of those are part of what turns on if you try to move the vehicle it will not move unless it is an EV mode and even then it only works for several feet but you can't get over a few miles per hour if you are on the highway like I was going 65 mph and there's traffic is extremely dangerous the only reason I was not hit was because I turn my emergency lights on and was able to maneuver my vehicle to the shoulder safely had I been in a more busy section of the road or had I been in an area where I could not get off the road I would have been hit by another vehicle. Honda has stated they can't find anything wrong with the vehicle but a quick Google search shows that this is a common issue and I have a video of the dash with all the warning lights should anyone need it as well as photos.
This Honda Accord Sport SE has had electrical problems from the day I received the vehicle. Every time I went for an oil change at Bommarito Honda I mentioned it to them and they said “yeah the new Hondas do tend to hand a lot of those electrical problems” so with this the problems continued to get worse. Sometimes the buttons do not work, sometimes they do, sometimes the lights don’t work and sometimes they do and sometimes the safety features and break system automated itself. I have slammed my head on the steering wheel on multiple occasions. I believe this needs to be looked into because the malfunction of the car falsely reports danger and caused an accident. Yes every time it malfunctions it flashes briefly and so quickly on the screen .
My vehicle is currently suffering a failed head gasket. I was alerted about this issue from local mechanics and friends way before it actually happened. I took it to services and regular maintenance even more frequently after that. However, it still failed no matter what. I took it to the dealership, they even admitted that this is a known problem for this generation of vehicle. They still proceeded to ask nearly $7000 to fix it, saying that even though this is a known issue, there was no recalls on the vehicles so they could not waive or deduct the fees.
I am writing to file a complaint on the service that was provided at Vann York Honda. On February 17, 2026, I was returning home from work and my car had a hard idle at start up. I was able to drive it home without issue. The next day, February 18, I got in my car and I had another hard idle start with many check engine codes appearing on the dashboard. I drove it to Vann York Honda in High Point, North Carolina for service. I was told it was a faulty fuel injector causing the problem and that it needed to be replaced. I left the car there over night and paid for the service; approximately 3,000. I got the car back on February 19. On February 20, I again had a rough idle on start up. I brought the car back to Vann York Honda and advised them that I was experiencing the same issue as before. The mechanic brought it to the back and advised me that he could not find anything wrong with the vehicle and that it is running fine. I expressed my concerns with the vehicle and he stated that without a error code or check engine light being on, it would be difficult to diagnose. The technician and the advisor said to keep driving it until a light comes on saying there is a problem since they could not find an issue. in the following 2 weeks, I had regular rough idles on start up and the fuel efficiency dropped approximately 6 miles per gallon. When I filled the car with gas, the fuel range dropped from 540 to 370. When I called about that issue, they said they reset the computer when performing the previous service on the vehicle and it is taking time for the computer to "learn" the car again. On March 6, I brought the vehicle back to Vann York Honda due to many check engine codes appearing on the dashboard. On the way to Vann York, the service advisor called me and stated that she would be reaching out to Honda Corporate to see about Honda paying for some of the cost of this service. My wife and I drove into the service bay and I spoke with the service adviso
All the lights came on in my car and it wouldn’t accelerate. Brought to dealership and they stated it was a blown head gasket and it was a known problem with the 1.5 turbo cars. There are also 2 others problems that are known problems with these cars and Honda isn’t doing anything about it.
The Body Control Module has gone out on my 2021 Honda Accord. Yesterday, when it went out, it affected ALL ADAS Features, in addition to key functionality of the car.
I am reporting a serious safety concern involving my 2021 Honda Accord Sport SE. The issue began at approximately 78,000 miles when multiple warning lights suddenly appeared on the dashboard while driving. At the same time, the vehicle began shaking and had difficulty accelerating. The engine felt unstable and the car struggled to gain speed. I immediately took the vehicle to a mechanic where it was diagnosed with an engine misfire on cylinder 3. The spark plug and ignition coil were replaced. After this repair the vehicle appeared to run normally for a short time, but the exact same symptoms returned shortly afterward. The vehicle again began shaking while driving and experienced loss of power and poor acceleration. This creates a serious safety concern, especially when merging onto highways or driving in traffic where sudden loss of power could lead to an accident. After researching this issue, I discovered numerous complaints from other owners of 2021 Honda Accords describing the same symptoms that ultimately resulted in blown head gasket failures. These complaints appear in the NHTSA database and other consumer forums. The pattern of engine misfires, shaking, and loss of acceleration appears to be consistent across many vehicles with similar mileage. Despite the number of similar complaints, there are currently no recalls associated with my VIN. I believe this may indicate a broader manufacturing defect affecting these vehicles. I am requesting that NHTSA investigate this issue further to determine whether a safety defect exists that could require a recall or other corrective action.
I turned my car on and it didn't want to crank up. Once it did crank up every warning light came on. My son ran the code and P00087 came up. I tried to drive my car in my parking lot and it kept stalling like it was going to cut off. Now I drove my car earlier in the day and didn't have any problems. It wasn't until after my car sat throughout the day when this took place. I know it's a recall for fuel pump issues but my car isn't included.
There are two locations in the town I live where I am driving under a bridge, and there is a dark shadow on the road from the bridge. My car’s accident mitigation braking system turns on at these locations and suddenly brakes the vehicle. This is not safe as people are traveling speed limit around me and I can cause an accident this way. About a month or two ago, the car behind me almost hit me at one of these locations when my vehicle’s automatic braking system turned on. It was made to prevent accident and brake if there is a vehicle, but because it is braking due to a dark shadow coming, it is not working properly and needs to be looked into. I called Honda and they want me to pay hundreds of dollars at my local Honda dealership for a diagnosis, I do not feel like I should be responsible for that fee as this is a safety feature that is not working as it should and instead making it less safe for me and drivers around me.
Head gasket blew randomly. Just hit 100,000 miles. I was on the highway and my speed just started to decrease 65 to 35
Stretch timing chain 1.5 T, 86000 miles. It is very common in these motors. Just had to pay $2400 to have it replaced
Financed a used 2021 honda accord sport in April of 2024 with 68,671 miles. About a month ago, with no warning signs of any sort such as overheating etc...my car did not want to start, finally started but was sputtering with a rough idle, my dash lit up with like 7 or more warning lights. Including a flashing check engine light. All the were safety warnings from braking system not working, to power steering to emissions failure, etc... and to take to dealership. Got the car to a local mechanic to get a diagnostics reading and was told I had a misfire in cylinder 2. Replaced the #2 coil and spark plug. Thought everything was fine until picking up my daughter from school and then all those warning messages lit my dash up again including the flashing check engine light. Car started sputtering and went into limp mode. Lost power and by the grace of God was able t9 coast off the major Blvd away from traffic and out of harms way. Very, very scary. My life literally flashed before my eyes. Not only my life was in danger but my daughters along with other drivers around me. So I took it back to mechanic and he ran diagnostics again still had a misfire. He could not pin point the exact problem. Took it to the dealership and they confirm it was a faulty head gasket between CYL 2 and water jacket. And they quoted me a price of 5,998. Which i can not afford. And feel Im not responsible for catastrophic major mechanical failure. I maintenance my car regularly thru the dealership so they have record of me properly maintenancing the car. Head gasket failure at 80,000 miles is absolutely unheard of. Until I started researching and come to find out this is a design flaw made by Honda. I was flabbergasted with the amount of people with the exact type of problem. Im afraid that even after repairing this problem that it may happen again down the line. And that would be putting my life in danger. Vehicle is still at dealership being that I can not afford the repairs.
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.
All lights on dash. Fuel injectors need replacing at 35000 miles.
It makes false things there is no car but it brakes by self for nothing
While driving the automatic brake system randomly starts flashing brake across the instrument panel and begins to brake the car. This does this while there are no other vehicles or any type of obstacles near the vehicle. It also, does it at random caution lights for the fire department on a 4 lane divided highway. There is no way to stop it from doing so. This happens frequently and leaves the driver with no control over the braking system.
Vehicle accelerated on its own and propelled the vehicle over a curb and into a building. This occured even though the gear shift was in the Park position. My grandchild and I were thrown forward as vehicle hit the building. Vehicle has not been inspected since incident occurred just yesterday, 11/20/2025. No warnings preceded the incident,
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.
Starts Vehicle at cold start and notice right away engine turbulence, engine light flashing, lost some coolant and white smoke. Scan vehicle for codes, engine misfire #2.
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.

I was driving northbound in on I15 in Salt Lake City when a Home Depot Bucket blew into my lane. I slowed down to change lanes when the Collision Mitigation Braking System (CMBS) deployed without warning, bringing my car to an almost stop causing a semi tractor trailer to hit me from behind.
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 ..
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.
The contact owns a 2021 Honda Accord. The contact’s spouse stated that while driving at an undisclosed speed, the Lane Keep Assistance feature became inoperable. The contact’s spouse stated that the feature was erroneously activated and deactivated. The contact stated that while the LKAS was activated, the vehicle jerked abnormally. The contact expressed concerns about the failure. The contact stated that the safety feature was very hazardous and could pose a risk to the driver and other vehicle operators. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 60,000.
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.

Head Gasket Blown i had a diagnosis ran at the honda dealership and it came back as a blown gasket its Preventing me to accelerate whole on the highway im going at high speeds and it slows down like im slmming on brakes
A transmission problem occurred shortly after a CVT transmission service was performed at an authorized Honda dealership, Classic Honda of Midland in Midland, Texas. After the service, the vehicle began experiencing abnormal noise, vibration, and harsh driving conditions. The vehicle was later inspected at another authorized Honda dealership, Ocean Honda of Burlingame, California. During the inspection, technicians documented that the CVT transmission fluid had been overfilled and excess transmission fluid had to be drained. After further evaluation, internal transmission damage was identified and the dealership advised that the transmission likely needs replacement. Ocean Honda of Burlingame provided an estimated cost of 10,101.13 for transmission replacement. Attempts were made to resolve the issue directly with Classic Honda of Midland in Texas, but the dealership refused to take responsibility or provide assistance. This condition may create a safety risk due to potential loss of power and unsafe drivability while operating the vehicle.
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.
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.
Hello, I have a 2021 Honda Accord Sport 2.0T Engine. The engine has a 2.0 liter turbo. I have had to replace two fuel pumps, which were covered my extended warranty. Another issue that I had to repair, and one that has not fully been resolved is the head gasket. I have been losing coolant at an alarming rate. Every two weeks I have to fill up coolant. I had the head gasket repaired at a Honda Dealership, and this is currently being diagnosed by another Honda Dealership, as I do not want to deal with the Honda Dealership in Cedar Rapids, Iowa. Currently, a Honda Dealership in Iowa City, Iowa is handling the issue, but the head gasket along with the cylinder head were originally repaired in October 2025. Since December 2025, I have been losing coolant on a regular basis. I still have 5,000 miles left on my extended warranty, but there have been many owners who have had their head gasket replaced, or are needing replacement, and Honda refuses to acknowledge that there is a manufacturing defect with the engine. The 2.0 liter turbo engine has a major design flaw with it's cooling passages, and Honda has yet to come up with a resolution. Having an engine overheat is a major safety concern! The current dealership is driving my vehicle on a regular basis, in fact the service advisor is driving it to work and back home (35 miles each way) to replicate the problem. At this point, a recall should be issued by Honda, as there is currently a class action lawsuit that has occurred in the state of California.
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.
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.
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.
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.
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 Infotainment system (car audio) in my car is intermittently extremely defective and very distracting. The system will intermittently have ghost touches on the screen, switch screens on its own, end GPS routes, place phone calls on hold, and all kinds of other things while I am driving. Searching the internet for a solution this is a problem that many owners are experiencing and they also report it to be extremely distracting and dangerous. A recall should be issued to correct the problem before someone is distracted and has a bad accident and gets injured or killed.
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.
My car slammed on its own brakes hard out of nowhere with nothing in its forward. The first time it happened was about 9 months ago while I was driving on the highway, it was a quick moment of breaking without any reason, but the car didn't stop. Today it happened again, the speed was about 30 m/h, the car slammed hard on the brakes to an almost complete stop. I was lucky, nobody was behind.
There is a loud humming noise that is starts at 40 mph. The noise comes and goes, but sometimes lasts for 10 minutes. It appears to be the Active Noise Cancelling unit. There was a previous bulletin Service Bulletin 21-053 about this issue for 2018-2020 Honda accords
Car won’t start, all lights on the dashboard are on and off and shows a message about brake problems and contact the dealership
The contact owns a 2021 Honda Accord. The contact stated while driving at approximately 30 MPH, the vehicle independently slowed down as if the brake pedal was depressed. The contact stated that a warning for the brakes and the collision mitigation and check engine warning lights were illuminated. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the turbo charger needed to be replaced. The vehicle was repaired. The contact retrieved vehicle however, several warning lights were illuminated. The contact parked the vehicle and had not returned it to the dealer. The vehicle was not diagnosed and was not repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to NHTSA Action Number: EA24002 (Forward Collision Avoidance). The failure mileage was approximately 98,000.
