36 Engine And Engine Cooling problem

Failure Date: 05/24/2024

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. .

42 Engine And Engine Cooling problem

Failure Date: 04/14/2023

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.

45 Engine And Engine Cooling problem

Failure Date: 05/10/2022

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.

46 Engine And Engine Cooling problem

Failure Date: 03/10/2022

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.

53 Engine And Engine Cooling problem

Failure Date: 12/24/2020

This vehicle when driving at normal speeds tends to make a high accelerating notices, it makes a person feel as if some other vehicle was passing on the left side at a very high speed. The first time I heard this noise, I moved to the right side of the road, thinking that a speeding driver was passing me. Since then, the vehicle continues to make this accelerating noise, six to seven times on a average of a thirty mile trip. I feet that this is not normal for a vehicle that is less than a year old. The vehicle makes this noise when in motion from 20-50 miles per hour, and might also make it at higher speeds. It never makes it while sitting in place idling.

54 Engine And Engine Cooling problem

Failure Date: 10/14/2020

From oct 10 to oct 14, I parked my car at off airport parking lot for 5days. When I came back, my car didn't start. My car was towed to the closest Honda dealership. I got the inspection report from the dealership stating that the reason why my car didn't start is due to bad gas. I went to the gas station, where I pumped my gas last time before I flew out of atl, to check with them. They provided me a copy of the system status report of 10/9/20 showing that there were no issues. So I went back to the dealership and they told me they have confirmed that #3 cylinder is full of water; they said they could get a fuel sample once I authorized them to work on the fuel tank removal and cleaning. Once they proceeded, they stated they focused on cleaning the spark plugs and performing an oil change which led them to find out there is internal damage to the engine. So they told me they would stop until my insurance company checks the car. They said they took multiple fuel samples and did not see water but there was water filled in the engine cylinders. They have asked me if the car was in a flood, but there was no massive rain or storm which flooded the area. They emphasized that it is not a warrantable repair as it is not a problem caused by the manufacturer, which sounded questioning. The technician told me if there is nothing wrong with the oil and fuel tank, then the only way that water can get into the engine is manually pouring lots of water through air intake, which also sounds ridiculous as I have never touched it nor there was no trace of someone trying to open my hood from inside and putting water. After I explained to them, they said they still cannot provide an answer as to why there is water, but it cannot be warrantable repair. If they do not know the clear cause of the issues, how can they strongly confirm it is not due to manufacturer issues?.
