Speed Control Cable problems of the 2000 Volkswagen Golf

1. Passenger front window drops down in door. Has happened twice. There were four other people at the dealer for the same problem at the same time I was there. I was told it was an "arizona" problem and that the part that holds the window up melts and breaks. I was driving down the highway when my window fell down causing me to become distracted by the incident and nearly causing an accident. 2. Air bag light went on for no reason. Cost tom me was $618 to replace a faulty airbag and wiring harness. I believe that should be covered even out of warranty since there is nothing I could have possibly done to cause the airbag to become defective. 3. Cruise control disengages when the right turn signal is applied. This happened for months unti the cruise control went out completely. I have heard this failure is due to a ribbon cable which gets broken in the steering column. My first one broke just before the 24k warranty expired. The second one broke on schedule at about 50k. This is very dangerous since if you pas someone with the cruise control on and then use your turn signal to get back over the cruise is deactivated causing the car to abruptly slow down in front of the car you were trying to pass.
