New car warranties are a marketing gambit, just like rebates.  They
are not a guarantee that you won't have problems.  They  are not an
indicator of the real longevity or quality of the vehicle.  Not at
all.  KIA has 10 year warranties.  Why?  Are their cars that good?
NO, it's because it is the only way they can get people to buy them.

Problems getting them to actually honor the warranty when something
does go wrong is not unique to VW.  I have heard horror stories about
people trying to get Chrysler to honor their warranties.

Sorry to hear of your troubles.  Hope they come around.
