You should feel "lucky" you got a 3 series. They gave me a Kia Rondo
)
Antenna quit working after 3 months so no radio for me. They fixed that.
The steering wheel on my x5 became squeaky after 5 months. They changed a spring and ever since the car pulls to the right. Every time i hit a pothole the steering wheel turns to the right 4-5``. They had the car for 3 more days...problem still there, but hey...they did something....they scratched my rim. I`m going back one of these days and i`m gonna park it inside their showroom.
My 10 years old 530i drives much better than this crappy x5.
