My 2016 cayenne is doing the same thing and started about 6 days ago
Register with Porsche and they will keep you updated. They sent me this info on how to reset the PCM that keeps on rebooting. I only had seen this a few times but it went away on its own. Anyhow here are the steps from the email Porsche sent and hope it helps. 1. Press and hold the INFO button for approximately 10 seconds until the PCM reboots. 2.Press the CAR button. 3.Press the OPTION button or touch the tab of the same name in the header. 4.Select "SET PCM system">>"Reset PCM". 5.Select "Vehicle handover" This resets all settings to predefined values and deletes your personal settings and data (including addresses, destinations, radio stations, phone numbers, as well as the recordings in the Sport display). 6.Confirm the relevant prompt by selecting "Yes".
