2021 Honda Accord Electrical System

infotainment system glitching

Blend door actuator is making a loud clicking noise which indicates the blend door actuator is either broken or going out. This problem will cause the heat and air to not function correctly. This seems to be an issue on several makes and models of Hondas 2019-2021(possibly other years). My Honda has 46,000 miles on and always had scheduled maintenance completed.

I have experienced persistent and frustrating issues with the infotainment system of my 2021 Honda Accord Touring. These problems affect both the usability and reliability of critical in-car technology, impacting daily driving and reduces overall satisfaction. Specifically: 1. Touchscreen Malfunctions Symptoms: Unresponsive screens, freezing, and “ghost touches” (inputs registered without physical contact) disrupt navigation, audio, and other controls 2. System Crashes and Reboots Symptoms: The system may randomly crash, freeze, or restart, sometimes causing the entire dashboard to shut off—even while driving 3. Connectivity Problems Symptoms: Frequent disconnections or failures with Apple CarPlay, Android Auto, and Bluetooth, making it hard to use smartphone features safely 4. Blank or Malfunctioning Displays Symptoms: The screen may go black, fail to turn on, or show a white screen, obscuring navigation, fuel, and safety information 5. Battery Drain Symptoms: The infotainment system sometimes powers on unexpectedly when the car is off, draining the battery and risking further electrical issues. These issues are not new and have attempted to be resolved by a Honda Service Center (Honda of Westport, CT) with no resolution or ability to resolve.

Information console glitches randomly and will close out maps, play music, switch input sources, and will call/hangup without driver input. Initially happened maybe 1-2 times a month, however now happens constantly making the entire informatics system inoperable and is very distracting. I am unable to upload the videos of it glitching (this doesn’t allow video files) but can provide if needed

The control panel/display touch screen stops working and the display acquires a mind of its own. It begins selecting things randomly and quickly. Automatically changing the radio, volume, and calling people in my contacts. Major distraction while driving and has almost caused accident for me multiple times

Car won’t start, all lights on the dashboard are on and off and shows a message about brake problems and contact the dealership

Infotainment screen is glitching. Randomly selecting options, turning on GPS, turning off GPS, changing the stations, and just selecting the different options on screen without actually having touched it with a finger.

my radio is acting crazy it change by it self and change screens
