I own a 2003 Passat 4-motion. I purchased it from the dealer in July of 2005 when it had 42,000 miles on it. Almost immediately I noticed two things about the car: first, it sometimes hesitates when trying to accelerate and then when it does finally take off, it "leaps" forward. Second, when shifting down sometimes, it does not do so normally but will actually jerk the car badly and make a "clunky" sound, like the transmission is failing. This seems to happen when you don't come to a complete stop and then try and accelerate again, like stop and go traffic. I have had the car back to the dealer many times and have been told that this is just a "characteristic" of the car and that there is nothing they can do about it. Overall I am very disappointed in the car.
