Solution
1. Preparation
  • Gather tools: flathead screwdriver, a flashlight.
  • Ensure the vehicle is parked safely and powered off.
  • Disconnect any devices from the USB port.
2. Inspect and Clean the USB Port
  • Use a flashlight to inspect the USB port for dirt, debris, or physical damage.
  • If debris is present, use a can of compressed air to gently blow out any dust or particles.
  • If necessary, use a soft, dry brush to clean around the port without damaging it.
3. Check for Software Updates
  • Turn on the vehicle and access the touchscreen.
  • Go to "Software" in the settings menu.
  • Check for any available software updates and follow the prompts to install them if necessary.
4. Perform a Soft Reset
  • With the vehicle on, press and hold both scroll wheels on the steering wheel until the touchscreen turns off and then back on.
  • Wait for the system to reboot and check if the USB port functions correctly.
5. Inspect Wiring and Fuses
  • Open the front trunk (frunk) and locate the fuse box.
  • Use a flathead screwdriver to remove the cover of the fuse box.
  • Check the fuse related to the USB ports; replace any blown fuses with the same amperage rating.
  • Reassemble the fuse box cover securely.
