I have not heard quite that description before. Could be your pads are giving you some sort of wear warning.

The GPS is not associated with that however.

I think we need a better explanation, can you tell us in YOUR launguage and see if we can get a better feel

Your OPC/dealer needs to put a PIWIS tester on the car run diagnostics.

With the symptoms you are having I am sure it will find a fault or two.

Now, it is 2013, and the same problem happens.

So, finally , what did the dealer changed ?

I drive also 2004 cayenne. and it's fine until recently.

After few minutes use, it automatically applys brake when u stop traffic light, and if you press pedal to go, it'll brake u again, and keep u slow, or not moving (the psm light will on, when it auto brake u)
