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.

The 1st thing that happened was that all the components of ADAS stopped working in the spring of 2023. All the warning lights turned on in the middle of my commute home from work. It was very intimidating because I thought the car was going to stall in the middle of the highway, so pulled over to the side. I contacted Honda dealership and they were going to charge me to diagnose the problem. So I went to Autozone and it diagnosed my problem as "System too rich (Bank 1)". I went to an independent mechanic and they had the same warning on their machine as Autozone. They tried replacing an oxygen sensor, that did not work in getting rid of the problem with all my warning lights turning on. Again the ADAS component lights turned on and the system did not work. The next thing they did was replace 4 fuel injectors. I have not had any issues with my car since concerning this problem with fuel too rich.

During medium acceleration the vehicle engine lost power and all the instrument panel warnings went off. Dealership said a blow head gasket. There are many threads online saying that there needs to be something done because the Honda 1.5 turbo motors are blowing head gaskets prematurely under 100k miles. Mine 2020 Accord has 108k and has been driven with care as I-??m a middle aged male commuting to and from work with the car. Some sort of investigation needs to be done to show there is either a design flaw or a gasket flaw.

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.

I brought my vehicle into the dealer for a recall software problem and to fix an oil leak coming from the valve cover. They replace the valve cover gasket and performed the software recall. As of now it still shows that my vehicle still needs the software recall. One week later after the oil leak repair, a massive oil leak formed at the valve cover causing oil to cover my engine bay and exhaust causing a burning smell and possible fire risk. Every weekend we drive out of state to tournaments and I was unaware of the leak. I brought it back to the dealer and they said it was residual oil from the previous repair. I was skeptical but believed them. One week later the same massive oil leak and problem occurred in my engine bay and driveway. Having no confidence in the dealer and being an ASE certified master mechanic, I decided to fix the problem myself by replacing the plastic valve cover assembly. I remove the old valve cover and found it to be extremely warped not providing a proper seal. The first time I brought my car into the dealer the service advisor said this is the second one this week that we-??ve seen. I have a hard time believing that my vehicle is the only problem with this. I am extremely dissatisfied with the service from the dealership and the lack of concern that my life and my sons life was put in danger with a fire risk. I am currently seeking reimbursement for the part that I paid out-of-pocket. About US$150.

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.

While travelling at highway speeds, rainy weather, the engine completely shut down. Engine light illuminated. Did not want to pull over on shoulder so glided to exit ramp. Turned vehicle off and then restarted with no issues. Drove approximately 150 miles to nearest Honda dealer. They inspected and said 'no diagnostic code' was registered. I took to my dealer and they tried to recreate but could not. They also found no codes. Had my family in car when full power loss. Very dangerous situation. I immediately activated the flashers. Drove in the right lane of interstate highway rest of way to dealer and home.

I leased my vehicle a year ago, I had electrical issues with my old car so I wanted a brand new car that was reliable and safe for me and my children. In the first months the car was fine but after about 4 months the car would smoke from the exhaust pipes randomly. I took it for maintenance as the car system directed but the repair shop never said there was anything wrong with the exhaust system. A month or so past and one day I got in the car and all the lights on the dash board were in. I was so freaked out because it was a new car and no warning lights should of been on. I took it to Honda repair services and they found out that a mouse went in my engine and chewed some of the electrical wires. The cost of the repair was 1700 which is extremely outrageous prices to me. Anyway I was at hospital at work and I got the call from the mechanic saying I would have to pay out of pocket because it wasn't a factory default. So I went home and did some researching and I found out Honda had been using soybean it peanut butter oil to lube the wiring, and that's what attracts rodents to your engine. It also started that Honda wire protection tape was out of stock because some many customers had there car wires eaten by rodents. So I was so pissed off that I called Honda corporate and they told me there is nothing they can do. I feel as though this is a big safety issue, why would Honda put parts or use oils in the car engine that attracts rodents. This to me is, unfair to honest hard working customers that pay Honda there money expecting to have a safe and reliable vehicle.now I just found out there is a recall on the vehicle because the car started smoking out the exhaust pipes once again. I am very disappointed in Honda.
