27k, 2 years on a very early '18 model.
Problems:
Hatch Rattle - Fixed by adding washers to the trunk lid.
Brake pulsating - Initially fixed by re-bedding the brakes. Problem started coming back every 2k miles though, so I replaced rotors/pads with sportier stuff.
Auto Start/Stop not running - Don't know, don't care. Probably need to put the battery on a tender for a day (I have a sub/amp connected which probably drops me below 12.4v under load), but I prefer it broken. Lol.
Paint chips on hood - Damn thing is a paint chip MAGNET. But ah well, it's a car, not a museum piece.
Otherwise, just normal maintenance, Oil changes every 5k, etc. On second set of rear summer tires, fronts still going strong (Though, I do run winters Oct-April, so wear on the summer tires is halved)
