I have a 2011 Cayenne and the entire bank of LEDs on the hatch and on the body that are not working on the drivers side. No light on the dash to indicate a light out, and not sure there is one on this model as they are LEDs versus a bulb.
Any thoughts on where to start looking for a problem?
I didn't find the right solution from the Internet.

Regarding your issue and since you mention that the rear lights use LEDs instead of bulbs and that you do not have any error indication on your dashboard, it could be that the LED power drive circuit is out. The LED power drive circuit is responsible for notifying the ECU of a lights failure (and then the ECU provides the dashboard indication), if the circuit board is damaged it will not power on the LEDs. Usually these power boards utilize a MAX16804 to control the LEDs, if this one fails, the main ECU will not be able to detect the issue (and give you a dashboard indication).
I would either ask my local car dealer for assistance or a specialized electrician for cars. Sorry for not being able to help more.
