 Jettas are a maintenence nightmare!  Since I got my Jetta (new in 1998), the following are only some of the problems I have had (most occured REPEATEDLY or were never resolved): window motors went out 6 times, cruise control (fixed twice, still doesn't work), volume control on radio, side plastic moldings don't stay on, keyless entry broke less than a year after buying, faulty front spoiler.  To top it all off, I just found out I have $7,000 in transmission repairs.  Everyone who I have spoken with has had similar problems and several VW owners I know have or are trying to get their cars declared lemons.  I am NOT a person who complains at much...but it is ridiculous that VW is still in business.
