A ghost or phantom touch, where random touch inputs occur on the infotainment screen display, and/or the infotainment display is non-responsive to touch immediately after having been cleaned, wiped, or disinfected may occur on some 2019-2021 Buick, Cadillac, Chevrolet and GMC models equipped with infotainment system RPOs IOS, IOT, IOU or IOV. (Fig. 18) The phantom touch or non-responsive conditions may last the entire ignition cycle. After the radio has gone through a sleep cycle, the conditions are no longer present.

These infotainment display conditions may be caused by the presence of liquid or certain physical touch during the boot-up sequence that can corrupt the display boot-up for that ignition cycle, causing false touch input or no touch input to be received until the radio can reboot.
Cleaning the Infotainment Display
When cleaning and disinfecting the infotainment display, always have the infotainment system turned on. Wait for the vehicle brand splash animation to complete. Using a clean towel, apply the cleaner or disinfectant on the towel. Do not spray any cleaner directly on the infotainment display. Wipe the display surface with the towel. Be sure to always dry the display to ensure there is not any liquid, debris, or streaks on the display.
TIP: Refer to the latest version of Bulletin #06-00-89-029 for interior cleaning precautions, steps, and suggested product usage.
After cleaning the infotainment display, if the phantom touch or non-responsive conditions are present, turn off the ignition, disable Retained Accessory Power (RAP), and allow the system to go to sleep (at least three minutes). Verify the conditions are no longer present. If the issue persists, check that the display is thoroughly clean and completely dry before allowing the system to go into sleep mode again.
