2021 Honda Accord Hybrid Electrical System Problems

I purchased my vehicle in March 25th 2024 a message on my dashboard saying engine is too hot so in August of this year I took it to the shop for a diagnosis test and they told me that the car didn’t run hot when they drove it so again in October 10th I was driving home and my car lost power on the freeway so I pulled over and then all my lights on the dashboard came on so I took it to the shop on October 13th and they told me that my head gasket was faulty and my coolant system was faulty. To me a major problem should have not happened within a years time and I had my maintenance done on my car like I should have.

Occasionally the touch screen will have phantom touches and start randomly acting like it was clicked in random parts. This makes it do random things like switch from navigation to radio to calling random numbers. While driving this is especially distracting and poses a safety hazard. The issue is reported many times online and seems to be common especially when they temperature outside is above 70 degrees.The only solution from Honda seems to be to pay to replace the screen but it’s not a true fix as it can happen again.

Shortly after purchasing this 2021 Honda Accord Hybrid (used, from a dealer), the infotainment touchscreen began to exhibit phantom touch behavior — the screen activates or presses buttons on its own without user input. This causes menus to change, volume to fluctuate, navigation to exit, or apps to open/close while the vehicle is in motion. It occurs frequently. The issue is not related to driver error, screen protector use, or moisture. The system has been rebooted and factory reset without improvement. A dealership employee has personally witnessed the issue in person, and I have recorded video proof of it occurring. This behavior is distracting and unsafe, as it pulls the driver’s attention away from the road unexpectedly as the screen flashes, and produces audible beeps. This issue makes it difficult or impossible to control basic vehicle functions like audio, phone calls, or climate. On one occasion, it rapidly switched inputs and opened screens while I was actively driving. Given how many critical systems are integrated into this touchscreen — including vehicle settings, audio, climate, backup camera interface, and navigation — a malfunction like this compromises safe operation of the vehicle whilst the vehicle is in motion. This defect was not disclosed prior to sale and was present within the first few days of ownership. I urge NHTSA to investigate this issue for potential design flaws or hardware failures in Honda’s infotainment systems, particularly in Accord Hybrid models with the Display Audio touchscreen.

This issue has been happening since purchasing my vehicle in 2021. While driving my 2021 Honda Accord Hybrid in warm weather (above ~60°F), the infotainment touchscreen malfunctions frequently. The screen registers phantom touches on its own—switching menus, blasting the radio, canceling navigation, and dropping phone calls. After each phantom touch, the screen becomes completely unresponsive for 30–60 seconds, leaving me unable to access key functions like navigation or climate controls. This happens almost daily in warmer conditions, especially on longer drives. My Honda dealer replaced the audio unit, but the problem persists. They acknowledged it’s a known issue but have no fix. This malfunction is a major safety risk and makes it difficult to comply with hands-free laws, as I’m forced to troubleshoot the touchscreen while driving.

Cannot turn on car. Cannot put into drive. Error Message: Power System Problem. Do Not Drive.

The screen randomly freezes or toggles between different screen without user input. It will randomly exit navigaton, end calls, increase volume, etc. This happens irrespective of day or night and whether I am using Android Auto of the factory navigation. Several times it has ended navigaton while driving cause me to have to pull over to avoid going in the wrong direction or missing turns. The system has also had its software updated the, factory reset and software reset with no improvement in the situation.

I saw the investigation of hat the NTSB is opening into problems with the CRV and a handful of other vehicles. I think you should add the Honda accord hybrid (touring) to this investigation. I was driving on a road with speed limit of 55 mph. In full evening traffic. My check engine light flashed on, and I immediately called the dealership to set an appointment. Within one minute of that light coming on, I lost all acceleration power, it just dropped off in the middle of the high flow of fast traffic with no shoulder. I had to find a way to force people to let me over going less than 5 mph to get to a safe shoulder. Then my car just stopped. I was on the phone with the service department at Honda when this happened and they were like, yeah sometimes that just happens. You get to the side of the road within a minute or it will shut off while driving. They made it seem like it was a super common and well known problem. That is ridiculously dangerous. I mean, ridiculously dangerous. I was absolutely terrified I would be slammed by a car on the highway. I got my car to the dealership for a full diagnostic, that they tried to charge me for, but they didn’t find anything. And they said it was probably nothing because they had no proof it happened. That is about it, nothing too terrible, but that has way more potential problems than my scary incident alone. Thank you.
