Gotta say, so far (9 months of ownership) have been nothing but favourable.
The only issue as been warranty bits, such as white worm on caps - sorted.
The BIGGEST problem with VW is the sheer inconsistency between dealers, AND for that matter, departments in those dealerships. There are levels of poor professionalism, incompetence and underhandedness.
Sadly, this does reflect on other dealers. I went through 6 dealers before I found one that I bought my GTI off. Sadly, the Customer service afterwards was very poor.
But my local dealership (not the place I bought the car from), have rubbish sales, but so far, very good service department (until proven wrong)
I have yet to experience VW headquarters, but it can't be any worse than IM (Subaru people).....
