 I bought a 2018 Tiguan SEL Premium Plus.  I was very excited about the styling and the quality of the drive.  The model that was delivered to me in the color combinations I wanted (Silk blue with stone interior) had several issues immediately.  The rearview mirror, for example, wasn't attached correctly.  The lane-keeping aids only rarely showed green, rather than orange/yellow.  Most irritating was a clicking sound that came from the B pillar(?) next to the driver window.   The While the dealer was able to fix the rear-view mirror (after waiting a week for the appropriate adhesive) and then another week when they decided to replace the windshield entirely, the other issues were never addressed.  In fact, they had an Engineer from VW personally go through the car.  The lead mechanic wasn't able to get the rear hatch to open with the foot swipe gesture reliably.  Even though they said the car was solid and checked out, a quick trip around the block demonstrated that the clicking/torquing noise from the B-pillar was still there.
