In my first post I forgot to talk about how my engine is whining a little when I accelerate? I also feel a little bit of a rough downshift when braking? Almost like I'm in a car that was shifted into low gear. Very strange feeling? I'm concerned already after owner my 2013 Cayenne S for about 3 days? Are these issues normal or am I doing something wrong? This is my first Porsche so I'm still getting used to the technology as my dash and console have more buttons than a Cessna.
