We have had 2 Cayennes in recently with rear end water leaks ..
2011 and 2012 model years .. both have had the rear sunroof water drains blocked.
In one case the water leaking onto the amp and rear control unit .. amp had to be replaced .
You can drop the back of the headlining , remove the D pillar trims and just about get at the drains to remove them and blow through .
A heads up basically to get your cars checked .
Some images below including a pretty nasty roof seal .
