2016, somewhere north of 40k.
Bouncy suspension has settled down over the tens of thousands.
Drivetrain, braking, etcetera has been pretty solid. Love the vehicle through and through. Here are the exceptions...
Paint chipping from rear hatch.
Really thin clear coat elsewhere. (more of a complaint than a problem)
Didn't take long for rust and bubbling paint to show up in hidden areas. (car is driven to dry after every rain... **not** allowed to sit wet for indefinite periods)
Water intrusion issue from new. Dealer recaulked windshield on first visit. Smelled like they recaulked everything second visit. Inside windows still fogged up after sitting through a rain in the sun. With each visit I only got new problems so I eventually fixed it myself.

Unusual noise with sunroof tilt. Dealer replaced sunroof. Noise was different, but still present. Eventually fixed myself. Tilts and slides quieter than it's ever been. (see link above)
Clack noise on clutch release... basically as the trans is loaded. No problem found with first visit. Reproduced noise leaving the parking lot. Second visit, told them in writing it's the dual-mass flywheel, along with how to reproduce. They were to diagnose and call me prior to doing any work. Ignored... replaced axle shafts, which of course made no difference. That only resulted with new problems that I've fixed and will eventually fix.
Other than issues with "service" not resolving issues, but instead creating new ones... it's been steller. Warranty does no good of you can't trust your henchman to perform quality work.
