I have had my 2004 vw Touareg since June 2006 and have had problem after problem with the vehicle. The catalytic converter went out within 6 weeks of buying the car, the drive shaft had to be replaced, the air conditioning compressor had to be replaced, the brakes have had to be replaced and I am getting another "check brake pads" error again, the tire monitoring system continually tells me I have a flat, the radio amplifier was making a loud cracking so the dealership replaced a fuse and blew the 2 back speakers (which they would not fix, hewlett vw in georgetown, texas), the auto differential is going out. There seems to be no end in sight for repairs.
