Unhappy with service from VW

Ive been a proud owner of the VW brand for over 15 years, but not any more. My vehicle is under warranty and Ive learnt that the extended warranty im paying for does not cover the issue im having, after being told by the service advisor that its a common problem with this model. Whats the use of purchasing these expensive warranties that is useless? Im disappointed and appalled at this. Ive never needed to read reviews but now realize that so many people are having issues with vw, I never thought it would be me, once dedicated to this brand, im considering never to purchase another vw again after this experience.
