 After about five weeks, the transmission in my 2003 Volkswagen Passat failed (fortunately the warranty covered it, at no cost to us).  Throughout the time that we have owned this car, we have had it in the shop for warranty issues more often than we like.  There is always for some molding or other annoying piece that really has no business failing off.  Despite the legendary quality of German engineering, little problems with this car have been getting to us, like the windows freeze shut at the slightest hint of ice and you can't open the rear hatch without unlocking it.  It has been difficult as a family vehicle, particularly with two young kids and a dog.  It is just too small for our family.  Other than that, it has been a great car.
