I'm not sure what you man by "interface". Would that be the LCD screen in the instrument cluster or the infotainment system? If the latter, mine does that occasionally, but turning off the car and restarting it a few seconds later clears it up.
Might be having the same issue, the center console touch pad buttons.
Until I can find a way to disconnect it, try pouring some isopropyl alcohol over the buttons, let it sit a little bit and wipe it down.
Horrible placement for the thing
