 I totally agree that VW doesn't stand behind its products and the dealerships are very incompetent.  I have just had my Passat for 8 months and suddenly over the last two weeks the mileage dropped to 10 mpg on highway!   I took it to the dealership and they say they can't find any problem and hence cannot help me out!  All they did was scanned the computer to see if there were any problems. Further, they took my car for a spin and put 100 miles on it  (50 miles more than what the invoice said). This is rediculous. I would never trust them or VW again.
