Upon initially purchasing my Jetta there were no problems. But by the winter, it started giving me problems and hasn't stopped since. The only major problem that I have encountered is that gear sticks. When I say stick I mean, will not shift into Reverse or Drive until it feels ready, which could be 5 or 65 minutes. Taken it to the dealership 7 times and they cant figure out what it but assume its the brake light switch. So they keep replacing that. I wouldn't recommend this vehicle to anyone unless you have a very good warranty.
There are no favorite features. This was my first car and I hated that I bought it every time I paid the car note.
This has already been stated but whoever decided to put the cup holders right over the cd player was not a genius and should've been fired.
