TSB: Unexpected Behavior from Placing Items on Center Console Control Panel at Start Up - Oct. 2021

[Tooney]

The customer may report a number of varied unexpected behaviors, ranging from open trunk and fuel doors to wild climate settings to multimedia control malfunctions.

Technical Background: If the user starts the Taycan while a wallet, smartphone, or other object is positioned on the 8.4-inch center console control panel, this could cause the controls that are housed in the display to seem to malfunction once the object is moved or removed.
In its startup routine, the center console control panel calibrates itself and zeroes itself according to its current state. Any object lying on the control panel disrupts this calibration and the system expects that continuous weight. When the object is removed, the control panel interprets this as a command (perhaps multiple, simultaneous, sustained commands).
There are reports of:
• The PCM volume being set to maximum when the driver exits the vehicle.
• The vehicle remaining awake for longer than expected (which puts the battery state of charge at risk).
• The alarm system engaging unexpectedly. There are many other ways this condition could manifest itself.

Yeah this was reported last year - I think there are some post on the forum for it.
