general problems of the 2020 Honda Accord - part 1

All the lights on the dashboard went off when there was not any previously. With that issue the gas pedal was struggling to go over 20 mph, it was jolting when gas pedal is used.

Honda Accords have a 1. 5 l engine, which all have an issue with the head gaskets either overheating or mixing coolant into the cylinders. They’re all doing it eventually because there is a design flaw Honda doesn’t want to honor it and the car will just stop on you on the freeway because coolant touches the spark plugs. Honda is denying the issue when there’s a whole facebook page and internet, page of people saying the same thing they’re quoting and unreasonable amount to fix it almost the cost of the car. It is a very dangerous safety issue and eventually someone could die and needs to make a recall immediately before that happens. Most shops don’t even want to touch the car because it’s a safety issue. If we can get this past ASAP for anybody who has that car or anybody that’s gonna buy that car the safety for them in their family.

It is unknown what system failed. While coasting to slow for the stopped car in front of me, the car began aggressively accelerating without warning. Adaptive and standard cruise control were both off. Lane keep assist and road departure were also switched off. Due to the slick nature of the road, the acceleration left me traveling far too fast with little space to stop. After sliding to a stop, I was within a foot from the car in front of me. This failure very nearly caused an at-fault accident which there was nothing more I could do. Note that this happened roughly 40 mins into a drive, which was otherwise uneventful. No warning lights were present before, during, or after the issue. This car has been having phantom braking issues and power loss issues consistently since March and has spent significant time in Honda's hands for this issue. The vehicle has come to a near stop on the highway from the previous braking issues and has lost power, stranding me in traffic on a highway. It is suspected that the same system failure that caused those issues has come back up again. To date, thousands have been spent on repair "guesses" and tow bills with no end in sight to these safety issues. This vehicle has become a liability and, as a result, inspections are strongly encouraged. I have included photos of the floor mats as they were at the time, properly secured and not near either pedal.

Honda never contacted me about this recall or steps to fixing the problem to make sure my car was safe and running/working correctly. I would like the problem/recall to be fixed ASAP. I looked up my VIN on your website and this is how I even found out about this recall. Please help me get it fixed. Thank you.

All dashboard lights came on and car lost speed while I was driving on the freeway in traffic. I couldn't even use emergency lights. Lucky I didn't get hit and maybe killed. Thus had happened several times and after researching I see other people have the same problem.

Was driving on the freeway approximately 70 mph on Saturday October 4th, when car goes into limp mode and throws a engine light on, leaving me stranded on the freeway. Another occurrence one week later on Saturday October 11th when car went into limp mode again driving around 35 mph in the city. Both cases I turned the car off and on and returned back to normal, come to find out with the dealer it is a blown head gasket and their is coolant leaking into cylinder 3. A blown headgasket!!!!! everyone is having these problems.

Check engine, tire pressure, battery and every other light on the dashboard.

Every light on the dash board is on.

Emissions system problems see dealer light came on took to autozone reading stated turbocharger but light went off. Later all warning lights came on so took to dealership they advised turbocharger as well. After for weeks no light no longer on. More recently emissions system problems light started coming on and off, but this time it will go days without being on then will turn on or it can be on when I first start driving then later it's no longer on. I also had issue with all lights coming on again went to autozone got brake fluid since it was low and they went off. I feel it maybe issue of faulty sensory due to fact car drives fine and light doesn't stay on consistently. I also see Honda currently has proposed class actions for defected turbochargers so wonder if that issue with my car.

Subject: request for recall due to persistent dashboard warnings and engine malfunction dear [manufacturer Honda] / NHTSA, I am writing to formally report a serious issue with my vehicle. All of the warning lights on the dashboard remain illuminated and do not turn off. Additionally, the vehicle occasionally becomes undriveable, unable to accelerate beyond 5 miles per hour. I was informed that the problem is related to the engine. I brought the car to a dealership for inspection, but they refused to repair the issue because the vehicle had just passed 40,000 miles. They stated that the warranty no longer covers the repair, despite the severity of the malfunction. After doing research and speaking with other vehicle owners, I have learned that this issue is not unique to my car. It appears to be a widespread problem affecting many vehicles of the same make and model across the united states. Given the safety risks and the number of affected vehicles, I kindly request that you investigate this matter thoroughly and consider issuing a recall. Owners should not be left responsible for costly repairs when the problem is clearly a recurring defect. Thank you for your time and attention.

When the fuel tank was at 1/4 full/empty, the car started stalling on the highway. We were able to go to a gas station and filled the gas tank. The problem was gone. We went to our mechanic but he could not find the problem. A few day's later the gas tank was 1/2 full/empty and the same problem happened. We filled it up and the problem was gone. We went back to our shop and the mechanic did a diag but didn't find any fault codes. He advised to go to the Honda dealer to take a look at it.

While diving at highway speeds (first at 55mph in may 2025 and then again in July 2025 at 65mph) I got a warning on screen about power loss and a critical failure and that power will be reduced and to stop at the side of the road. Within 30 seconds or a minute of the warning the car power cut out significantly impacting the speed and both times almost causing traffic behind me to hit me from behind. I took it to Honda dealership in dulles, va back in may 2025 and they told me it was the electric water pump which I had replaced. Now in July it happened again and this time I had my wife and child with me in the car as well as a guest. I had to pull over and all the warning lights started to flash (everyone of them). I have taken it back to Honda but having a car that goes from 65mph to 25mph on the highway with no warning to others is a recipe for disaster. Apparently this is a known issue with the hybrid system and the battery needs replaced (from online Honda forums) which Honda is not doing unless forced. I am still waiting for my dealer to get back to me but its exactly the same problem as the other notes I saw online. My car only has 46,000 miles.

Honda letter from dmv that I have to do. My car registration says that there is a safety recall that the manufacture of Honda should’ve contacted me, but I have not received anything and it has not been fixed so now what?I’m.

All the lights coming on on the dash.

I was headed to work going 40-45mph, as I was going I felt my car shift out and my speed dropped to 25 automatically. My engine light popped up flashing. I could not accelerate my car above 25, leaving me late for work, I had to turn my hazard lights on so people could know something was wrong but I could have been hit from behind. My car did not give me any notifications from my car on the issue it could be having like usually, (oil change, tire rotation, spark plugs, etc. ) after cranking my car again a few hours later, I noticed a difference in how it is cranking up. Honda dealership is wanting $150 to even look at the car for a possibility of repairs. I need to know exactly why it is happening and why a recall is not open if I have spoken to multiple people and they are having the same issues, all within this year.

My car displays every single light on the dashboard it’s been happening for about a year. It starts to shake when I turn it on sometimes it does it sometimes it doesn’t but now it’s a reoccurring issue and has been happening for the past six months we’ve brought it to everywhere. The engine is stalling and won’t go over 20 mph. I’m lucky if it gets to 40 . There’s a recall on my car, but my van is not covered underneath it. Looking to see if this can be looked into since so many people I have spoken to says that that’s what they’re experiencing until they got the recall fixed.

I am an 81 years old widow and am very afraid to drive my new 2020 Honda Accord. I am regularly experiencing an ongoing intermittent issue where my car stalls for no apparent reason. I've taken it to the Honda garage where I purchased it two times and no one seems to be able to satisfactorily address this concern. The first time I reported it to the shop (4/24/24), the technician didn't even pull it into the garage to investigate it. I assumed they would hook it to some diagnostic device and see if the cars computer would have some record of the fault. Instead, he jumped in, pushed some buttons relating to the lane keeping system (?) and claimed that would fix it, but it did not. I continue to experience the same problems. One example is when I take my car to the car wash, it stalls at the end and starts beeping. No matter what car wash I go to, it's the same awful experience, where they must shut down their equipment and come out to help me get the car restarted so as to get me out of the way and let everyone else out who are now stuck behind me (very frightening and embarrassing). I've also had the car shut off after hitting some small potholes. It will shut down and requires a few attempts to get it restarted from the middle of the road!again - I then took it back to the Honda garage where I purchased it for a 2nd time (6/3/24) and for some other routine maintenance. This time they told me that maybe it was caused by my toll-road ez-pass which was mounted to my windshield near the rear view mirror. As you may imagine, I'm beginning to think the reason for the inability to address the issue is either intentional, incompetence, or perhaps I have a lemon. .

For some reason the vehicle shift gets stuck in the park position. After continuous tries, it eventually goes into gear. Apparently, there is something wrong with the transmission and should be covered by warranty.

At speeds between 50mph a howling noise begins and gets louder as the speed increases to 55mph. The howling noise is quite loud. It stops after you get above 55pmh or you open a window. The dealer said he was not aware of this problem.

The anc module malfunctions already at only 67000 miles and causes a humming noise which is very annoying when driving. The ebreak also malfunctions during cold weather conditions. I have had to restart the car due to the electronic parking break not working properly. In case of an emergency I might need it and it may malfunction.

An unknown system or the fob recently started causing the vehicle's trunk to unlock and/or windows to roll down. This presents safety and theft issues since someone could enter the car or trunk without the owner/driver being aware of their presence. Also, the trunk popping open while driving is a distraction and blocks the view through the rear window. We traded a previous year's model of the same vehicle due to the same problem. The trunk light comes on if the trunk opens while the vehicle is in operation, but there is no way to know the trunk is open if the car is parked.

Unknown.

The vehicle's transmission stalls when trying to accelerate, causing unnecessary rpm fluctuations. While going downhill with the brakes applied, the rpm gauge spikes pass 4000 rpm causing the car to accelerate rather than slow down. When this occurs, extra pressure has to be applied onto the breaks to slow vehicle down. If enough space isn't given to the car infront, pressing the break will cause a crash. Accelerating too fast on the highway will cause blown head gasket if transmission is stalling. This seems like a common issue with 1. 5l engine & Honda's cvt transmission as other owners has been through similar issue & proven by independent service center. I've taken the vehicle to different dealer for inspection. Only recommendation is transmission fluid change. Dealers refuse to do anything regarding the actual issue at hand.

There several blind spots in this car, had a car accident due to blind spot.

Freon leaking from the evaporator.

On the morning of Nov 1, 2022, I was driving on an open rural highway in cool, clear weather with no other vehicles on the road. Suddenly I heard an explosive crashing sound followed immediately by the sound of broken glass falling. I was afraid to stop right there because a few years ago, there were several vehicles hit by rifle fire not far from me in northern colorado. As I drove, I felt a little air flow, as if a back window was partly open. When I came to a parking lot for a hiking trailhead, there were other vehicles in the lot and I felt safe to pull over. Examination showed that the sunroof on my car had shattered. Luckily, I had the sunscreen closed, or I would have gotten a face full of broken glass while traveling 55 mph. I reported to the sheriff. We tried to imagine what could have happened. I actually wondered if a random piece of meteorite had fallen from the sky, but there was no foreign object along with the broken glass. I filed an insurance claim. The damage has been repaired. I was not injured, but certainly shaken up because of the close call. Later I learned that other sunroofs have shattered spontaneously. I believe there should be a safety recall.

Driving on the interstate going about 60mph with no one in front of me or behind me and the car brakes by itself. This is the fourth time this vehicle has randomly brake.

Purchased new 2020 Honda Accord on September 28, 2020. On October 13, 2020 I was pulling into a parking space at a retail store. Going 2 or 3 miles per hour with foot on brake turning into space on my right with steering wheel turned to the right. Suddenly engine roared and car would not stop even with my foot firmly on the brake until it hit a pole. I have since learned it is called unintended acceleration. After crash I drove car to another parking spot. Car was in park and I was on the phone and all of a sudden engine roared - same sound when crash occurred. Honda sent their investigator out and told me all car functions were ok. Car was repaired for $7000. 00 on June 1, 2022 the same exact thing occurred as I was pulling into a parking spot on my right with steering wheel turned to the right. As the first incident engine suddenly roared and with my foot firmly on the brake car would not stop until it crashed into the store concrete wall. This car has something wrong with it. There are other stories out there with same story as people are parking the car. The car was towed to a collision shop and I am going to the Honda dealer I purchased it from to insist this car is a danger to me and others and I cannot drive this any longer. I first wanted to report this before I did anything else.

Driving on a two lane highway suburban area - 40 miles per hour in a 40 mph speed limit. No cars in front of me for at lease 1/2 mile - totally blank and clear road. A pick up truck behind me. Very little traffic. Suddenly without warning and knowing my foot is on the accelerator, the car brakes to a complete stop with no foot on the brake pedal! complete random braking for no reason. Luckily the vehicle behind me was far enough and not too close which allowed him to swerve and avoid colliding into me. He passed me and probably thought I was crazy. I called Honda and they told me to bring it in which I did. They performed many tests in all areas and advised they could not locate anything wrong. I know there is an ongoing investigation with Honda Accords and dangerous random breaking, thus the reason for this incident to be documented. The general manager of the dealership was in touch with me and advised he would be doing some research. I could easily have been killed if not for quick thinking of the vehicle behind me, and also luckily no car in front of me. What do you advise? this is extremely disconcerting to know it could happen again.

My car is a hybrid. At times, a very loud humming noise is produced, due to glitch in software with the anc. Noise starts and stops suddenly, intermittently, without warning, and is a safety hazard. Noise can build to be extremely loud and jarring, and can last for several minutes. Honda claims this is a cosmetic issue only and they are working on it. But the issue has been repeatedly reported by thousands of drivers over a multi-year period. Honda is ignoring any real resolution. Please help! this is frightening and disruptive, and makes operating the car unsafe. Thank you. It started about 1 year after ownership and was occasional. It is now happening multiple times, every time I drive my car.

The brake system failed. I received an error message indicating "electric parking brake system problem. Parking break not available. See your dealer". All of the abs messages, cruise control, etc. Appear and say, "see your dealer". My safety was put at risk because the break automatically starts without me even pushing the break. This happens without any given notice and appears before the message occurs. This happens while vehicles are behind me on main roads and also happens while on the highway going a high rate of speed (speed limit). There is nothing that can be done to stop it manually. The car stops on its own. No, I will be scheduling a dealer appointment, since the issues continues to occur. No, the message appears after the issue starts.

The anc (active noise cancellation) software is not up to date. It's causing a loud, uncomfortable booming or humming noise from speakers while driving. 2018-2021 models are having the same issue. Many Honda Accord sport 1. 5 or 2. 0 owners I talk to are experiencing the same problem. And are being told by local Honda dealerships they don't see any issue.

While driving at highway speeds (50 -55mph), the anc (active noise control) unit delivers a loud booming sound through the speaker system. The sudden and unexpected booming noise startled the driver causing temporary loss of control of the vehicle. The solution has already been identified in a service bulletin from Honda as service bulletin 21-053. The anc unit has incorrect software and requires replacement to fix and eliminate the safety hazard. The issue was noted June 29th, 2021; but, has not been escalated as a safety recall. I have replaced the anc as directed by the service bulletin and it has resolved the problem; however, other Honda vehicles have this same safety issue and if not recalled will continue to be a safety concern for all drivers on our highway. I would like to see this escalated to a safety recall level and customers notified to replace. I am disappointed that Honda has not proactively recalled this.

Just before March 2, 2021 shortly after purchasing this new vehicle I discovered a safety hazard in which the passenger window will not roll down, I brought it to hoehn Honda in carlsbad on March 2 and they oiled the window to make it work. I had concerns that they did not replace the motor mechanisms and it would fail again which it has. Today may 17 2021 I was not feeling ill at work and went to sit in my car to roll down the windows to get a breeze and again the passenger front seat window is stuck. One or two times it seemed like it didn’t work but on the next try it did after the repair. Now it’s frozen again. Having non-operational windows is a safety hazard and a passenger hazard, and a law enforcement hazard if pulled over and the window will not roll down. It is stuck in the up position. The dealership has no interest it’s a safety hazard and requires I drive it in and will not provide me a loaner car.

Last year a couple of weeks after I purchased my car I came out the store to discover the gas tank door open and the car was locked. When I called the dealership about the incident it was brushed off. The speed limit sign capture camera showed that the speed limit was 90 when I was in a 35 mile zone, it had captured the last two numbers a routing sign instead of the speed limit sign. I woke up one morning to find my car windows down, the sunroof open and the car was still locked. The keys were stored in a place where they were not touching anything, so there was no logical explanation for the windows to be down and the sunroof open. The car had not been driven for a couple of days prior to this incidence. I called the sheriff's office. On March 18, 2021, I discovered that the gas tank door was not locking at all.
