2021 HONDA ACCORD Complaints

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.

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.

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.

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.

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.

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

Honda head unit touch screen is glitching while driving. This causes my navigation system to shut down or freeze and then I am unable to use the touch screen entirely. The dealership has confirmed this as an issue that other people are experiencing as well.

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.
