Vehicle: 2021 Honda Accord Sport Subject: Intermittent Electrical Malfunctions, Multiple Safety Warnings, and Loss of Acceleration I am reporting ongoing safety concerns involving my 2021 Honda Accord Sport. On multiple occasions, my vehicle has displayed several dashboard warnings, including brake system, electric parking brake, vehicle stability assist, hill-start assist, adaptive cruise control, and electric power steering warnings. These warnings have appeared intermittently in the past and sometimes disappeared on their own. On October 18, 2026, while traveling on the highway at approximately 65 mph, these warnings had already been displayed for approximately 30 minutes to an hour when my vehicle suddenly began struggling to accelerate. Despite pressing the accelerator, the vehicle continued losing speed, and the RPM gauge remained around 2,000 RPM. It felt as though something was holding the vehicle back. After several moments, the vehicle suddenly regained power, accelerated, and the RPM increased. This was particularly concerning because I was traveling at highway speed. I also experienced electrical problems with the interior lights. While the vehicle was running, neither the automatic interior lights nor the overhead lights near the rearview mirror would turn on. They remained inoperative after I turned off the vehicle. Later, the lights began working again, but I noticed the right overhead light fading while the left remained illuminated. The battery was replaced earlier this year, in 2026. I am concerned that these intermittent malfunctions could result in a sudden loss of power or failure of important vehicle safety systems while driving. I am requesting that these problems be documented and investigated for a potential safety defect or recall. I have photographs of the dashboard warnings available as supporting documentation.

My 2021 Honda Accord Touring 2.0T has an intermittent touchscreen/infotainment malfunction commonly described as “ghost touch” or “phantom touch.” The touchscreen generates inputs on its own without the screen being touched, causing menus and functions to change unexpectedly while the vehicle is being driven. The malfunction is distracting because the infotainment system begins operating by itself and requires driver attention to correct or stop the unwanted inputs. The same center display is also used for vehicle information and the rear-view camera, which makes reliability of the display a safety concern. Honda Corporate has been contacted regarding the problem. I have been advised that Honda is aware of the issue but is not currently authorizing a repair because a permanent repair/fix has not yet been developed or released. I have an extended warranty that can cover a repair, but Honda has not provided an approved permanent repair at this time. The problem is intermittent and may occur unpredictably. The factory touchscreen remains installed and the vehicle is available for inspection. I am submitting this complaint because the defect can create significant driver distraction and affects a display that is integrated with important vehicle functions.

The infotainment/touchscreen system in my 2021 Honda Accord is malfunctioning and experiencing what is commonly referred to as “ghost touching.” This issue has been occurring since approximately March 2026. While I am driving, the touchscreen will randomly make selections on its own without me touching the screen. This is especially concerning when I am using GPS/navigation because the system can change screens, select different options, and interfere with the navigation information I am trying to view while driving. This creates a safety concern because the unexpected touchscreen activity is distracting and causes me to take my attention away from the road to correct what the system is doing. The issue happens without warning and can occur while the vehicle is moving and I am relying on GPS for directions. I took the vehicle to a Honda dealership regarding the problem. The dealership was made aware of the ghost-touch issue and stated that there is currently no fix available for it. The touchscreen and related components are still installed in the vehicle and are available for inspection upon request. The vehicle has not been inspected for this issue by police, insurance representatives, or any other outside party. There are no warning lights or dashboard warning messages before the malfunction occurs. The primary symptom is the touchscreen suddenly registering inputs and making selections on its own even though I am not touching it. The problem first began around March 2026 and has continued intermittently since then, including while driving and actively using GPS/navigation.

The car's infotainment system constantly glitches out and changes channels,outputs,texts,videos while car is being driven. It's very distracting and dangerous. It will literally do it 100's of times within a short period. It's much worse than any text messaging distraction, which is against the law. Several people with this car have the same issue. Also the car will break when there's actually nothing in the road that should make it break but it will just slam on the brakes.
