Touchscreen system in my 2021 Honda Accord Hybrid Touring is now having issues registering touches or is exhibiting ghost touches. This results in unpredictable selections for diverse systems like sound, touch free phone integration, navigation, etc. These are distracting in the extreme, and seem to be common during the afternoon hours in strong sun. This issue is partially mitigated via a hard reset, but this is helping less and less as this error becomes more and more common.

I’m not sure what it’s called, but the entertainment system where the touch screen is for radio, has ghost touches when the weather gets warm. Over the winter, this never happens. But during the summer, the screen starts glitching out and if I have gps going, this is a real safety issue because the ghost touches change the screen and I don’t know where I’m going. And it’s very distracting , the ghost touches continue every couple seconds.

On July 4th 2026, I was leaving from a restaurant that evening and within 5-10 seconds of me turning my car on, all of the lights on my dashboard turned on. I was slightly confused because there were multiple at once and my car was rumbling a bit from under the engine hood. Within a few weeks prior, I’ve been having with my digital car screen switching back and forth between tabs (from the radio, to my CarPlay, to the settings). It will be intermittent but fairly consistent. I plan to take my car to an auto parts store for a code test and battery/alternator test to see if there’s any further issues. I just purchased a new battery for this car within the 3 years of me getting it, 2 years ago and there shouldn’t be any issues. I’m not sure how to proceed and I really don’t have it in me to spend large amounts of money and time with repairs for a supposedly heavily reliable car. My current mileage is at 120,000.

My infotainment system is not working properly. It switches between screens, radio stations, etc., and sometimes turns off. It is very dangerous when I am driving using my map and the map either moves, stops working, or switches to a different screen. I have had to pull over in the middle of nowhere while traveling because the map quit working properly. It also cuts me off in the middle of phone conversations. I just put a random date below because this has been going on for almost a year now.

The vehicle suffered an unexpected loss of engine compression and dropped into a dangerous Limp Mode while driving due to a Cylinder 3 Misfire code (P0303). The manufacturer dealership misdiagnosed the mechanical issue using an unrelated 2.0L engine service bulletin (SB23-026) to clear the error. Six months later, the dashboard completely illuminated again with code P0299 (Turbocharger Underboost) caused by progressive pressure and compression loss across the 1.5L turbo engineering components. Upon post-visit inspection, engine fluids were found severely depleted. This ongoing engineering failure causes a sudden loss of vehicle motive power on public highways, creating a severe, recurring safety hazard that mirrors the active federal engine defect class-action litigation against American Honda Motor Co. This has happened 4 times with all the lights on my dash coming on Dec 2025, May 2026, June 2026 (2x)

While driving to work, the radio seem to have a ghost inside the radio. The screen has a mind of its on. The radio turns itself off and on by itself. It’s a safe hazard to driving with all that is happening. The radio will beep constantly while driving down the road and my teenager will not driving my car, due to being scared

I have been experiencing what’s being called “ghost touches” on google. This is a known issue that needs to be addressed. Also VIN number starting with 1HGCV need to be added to the fuel pump recall list. I’ve had to change both systems.

I am filing a complaint regarding the premature head gasket failure on my 2021 Honda Accord, which failed on May 28, 2026, with only 89,000 miles on the vehicle. A head gasket is a critical engine component that should last well beyond 89,000 miles under normal driving conditions and proper maintenance. I purchased this vehicle because of Honda's reputation for reliability and longevity, and I am extremely disappointed to experience such a major engine failure at this mileage. After researching the issue, I found numerous reports from other Honda Accord owners experiencing similar head gasket failures, particularly in newer models equipped with the 1.5L turbocharged engine. Many owners report engine misfires, coolant loss, overheating, and costly repairs at relatively low mileage. This suggests there may be a broader issue affecting these vehicles rather than normal wear and tear. My vehicle has been properly maintained, and I did not expect to face a repair of this magnitude before reaching 100,000 miles. The cost of replacing a failed head gasket is substantial and places an unfair financial burden on owners who reasonably expect Honda vehicles to provide dependable service. I respectfully request that Honda review this matter, investigate the growing number of similar complaints, and provide assistance with repair costs. I believe Honda should stand behind its products and support customers who experience premature component failures. Thank you for your attention to this complaint. I look forward to a prompt response and a fair resolution.

Infotainment center has phantom touches, the screen also freezes up and goes completely black when it is connected to a phone and also when it’s not connected to a phone. When car is connected via CarPlay for directions it will not display all the time or it will completely shut off in the middle of the directions, the only way for it to unfreeze or cut back on is if the car is turned off which makes it very dangerous. This has been happening for 2 years.

I have 2 issues and not sure if they are related 1.SRS system light came on and says see dealership. This one happened about 2 weeks ago. 2. While driving today all the lights on my dash came on including the check engine and all warning notices were going off. I was driving when this happened and it was alarming because I didn’t know if my car was going to die while I was driving. Neither problem have been confirmed by the dealership because they want 199 just to diagnose and does not include repair cost No one has inspected the vehicle No previous warning signs prior to either of these both happening

I have taken my vehicle in 3 times to have the recall repair completed and each time the dealership said they did it just for me to have checked the nhtsa website to see that it has not been completed.

Stereo randomly started glitching out

Infotainment system randomly cycles through menu, as if I'm pressing buttons on the screen. It will lose navigation, randomly call my contacts and audio will turn off and on. This is extremely unsafe. Once it starts doing this the screen becomes unresponsive to actual touch. I can't stop it if I want to. I'm stuck disconnecting my phone and using the screen as navigation, constantly looking down while driving or holding the phone to make a phone call. Local Honda dealerships have told me that it's a common problem with no solution.

Infotainment is malfunctioning and it is available for inspection. The screen clicks on its own, and leads to GPS errors, makes incorrect phone calls and does not respond to my inputs. It has not been reproduced by the dealer, but I have videos and have shown the dealer. It has not been inspected by others. There were no messages or warning lamps.

The touch screen display malfunctions and is often either unresponsive or it has ghost touches and moves across various screens while you are driving and during navigation. The system will make calls, activate voice assistance, move the map when navigation is active to where you can no longer see your route, switch between audio sources, open random apps, etc while driving leading to distraction. The touch screen will not respond to your touch but continue to do its own thing. This is dangerous while driving because it is hard to end calls, get back to your navigation, or focus on the road when voice assistants are activated randomly and difficult to turn off. There is not a reset button for this issue so it may continue the duration of your drive. The issue has been confirmed by a dealer with the suggestion to replace but online forums suggest this is a widespread issue and replacement does alleviate the problem. The vehicle has not been inspected by police or insurance. There were not any warning lamps, messages, or systems prior to the issue.

I bought my vehicle around May 2024. Initially, everything seemed fine. However, I noticed that my car was starting to slow down and would enter limp mode, preventing me from exceeding a certain mileage. Subsequently, all the lights on my dashboard began flashing, prompting me to pull over and call a mechanic shop. I had all the necessary maintenance and repairs performed as per the plan. After starting the vehicle, all the lights turned off, and it drove smoothly. A few weeks later, all the lights came back on again, and nothing showed on the OB2 Reader, which I thought was odd because something shouldve popped up if all the lights on my dashboard was going all crazy. The mechanic said the same thing and maybe thought it was the battery, sensors going bad, or even the wiring. But he checked everything and said he didnt find any issues. So I went home and the lights on the dashboard stayed on for 30 seconds and then turned off after I started the car. The lights turning on all at once on the dashboard became more frequent and this time, the check engine light illuminated, indicating a misfiring issue. I took the vehicle to a mechanic shop for a thorough inspection, and they made a few minor adjustments. However, two months later, the same problem recurred. All the lights came on again, and the vehicle misfired once more, accompanied by the check engine light. Upon further investigation, it was discovered that the issue was a head gasket leak. Additionally, the seat belt alert for the passenger and rear seats, as well as the child car seat, failed to function properly.

2021 Honda Accord EX-L, 1.5T turbocharged engine. Within 8 months of purchase at approximately 21,900 miles, I experienced three separate incidents of sudden complete engine power loss at highway speeds. During each incident the vehicle would not exceed 2,000 RPM and multiple warning lights illuminated simultaneously including check engine, TPMS, brake system warning, and Honda Sensing alerts. The vehicle was inspected by two independent Honda dealerships on multiple occasions including cylinder drop tests, leakdown tests, and full fluid checks. The vehicle passed every test at both locations with fluids confirmed properly maintained. Despite passing all professional inspections the power loss incidents continued to recur. The third incident occurred in a residential driveway with a passenger present and was captured on video. A Honda dealership subsequently diagnosed a head gasket coolant leak with an estimated repair cost of approximately $8,000. Research revealed numerous other 2021 Honda Accord 1.5T owners reporting identical symptoms regardless of maintenance history. This appears to be a known design defect in the 1.5T cylinder head where a narrow coolant passage represents a structural weak point that fails regardless of maintenance. Owners have been reporting this to NHTSA since 2024 requesting a recall. This defect created dangerous conditions at highway speeds with passengers present on multiple occasions. The vehicle is currently available for inspection at a Honda dealership. I am requesting NHTSA investigate and initiate a formal recall of all affected vehicles. i have everthing documeneted from the 4 dealship visit ive done since the start of the issue.

Infotainment Center: I am submitting this complaint regarding my 2021 Honda Accord Sport and the ongoing issues I’ve experienced with its infotainment system. This problem has been persistent, unpredictable, and increasingly concerning from both a usability and safety standpoint. Since purchasing the vehicle, the infotainment center has repeatedly malfunctioned without any warning. The screen will freeze, switch from setting to setting, or become unresponsive to touch input. At times, it will randomly reboot while I am driving. These issues occur regardless of whether I am using navigation, Bluetooth audio, or even when the system is idle. This also affects the ADAS, periodically, warnings will be displayed, and then not show up. What makes this especially troubling is how it affects my ability to safely operate the vehicle. For example, when the system freezes, I lose access to navigation directions mid-route, which forces me to either drive without guidance or attempt to troubleshoot the issue while on the road. Similarly, when using hands-free calling or music controls, the glitches can be distracting and require repeated attempts to regain control, taking my attention away from driving. I rely on my vehicle daily, and this ongoing issue has caused a great deal of frustration and concern. A modern vehicle’s infotainment system is not just a convenience—it is integrated into essential driving functions. When it fails, it directly impacts driver awareness and safety. I am requesting that this issue be investigated further, as it appears to be a systemic problem rather than an isolated defect. I hope that by reporting this, it may help lead to a resolution for myself and other drivers experiencing similar problems.
