The stereo system stopped working four months after I got the car. Luckily, my warranty replaced it.
I love my car, it looks great and runs smooth. One point I want to share with the readers is that when you start moving from a complete stop (say a traffic light), the car is considerably slower than most of the cars with automatic transmission. Sometimes I think people change their lane to pass me, however, once you are on 3rd gear and higher, it is a joy to drive.
Handles great, and is indeed fuel efficient (4 cylinders).
Most automatics are noticeably slower than their manual counterparts, so your acceleration problem is not down to the transmission. In the UK, the Passat 1.8T makes only 150 hp which I presume is the same as the US model. Not a lot really for a tonne and a half of car, even if the engine does have a lot of torque for its size.
