 After major camshaft failure within 250 miles of ownership on one of the last 2017 Q5's, our car was swapped by Audi for a new 2018 Q5.  While we agreee with what others have written about the new 2018 Q5, the initial quality issues that we've encountered around the steering wheel and driver side mirror are extremely disappointing.  While we pointed out both issues on initial delivery of the car, both have unfortunately become long drawn out issues with service and then corporate Audi got involved.  The driver mirror had some unexplained heavy caking on inside, sides and bottom (almost like paint primer) that service rushed to clean, which they only got about 1/3 off.  Then left us with the car, so that they could work on it again when we brought back to replace the steering wheel that had a 1" slit in the leather wheel at delivery.  Now the LED 1/8" strip on that side view mirror is popping out, along with moisture seeping in and service is saying it's not covered!  Would be interested in hearing from any other consumers with similar problem on the driver mirror and how you are resolving it, as replacing an entire side view mirror is quite expensive.
