I've had my 2014 Q5 for 4 days. It started raining yesterday on the drive home from work. To my surprise the rear window wiper DIDN'T WORK. I went straight to the Audi dealer in Stuttgart, Germany. They need the vehicle for 2 days to troubleshoot / replace the rear wiper motor assembly. Also the washer reservoir was empty. This is very poor quality control by the factory here in Germany. They didn't do a very good Pre-delivery Inspection if any at all or this would have been caught. For a $41k price tag this is totally unacceptable.
