I live in Boston USA and have a Feb 2012 Evoque from new. In last 3 months the tailgate failed to close on the button about 20% of the time. Dealer tried to fix it once (kept the car 36 hours) and claimed they had - but it failed again as soon as I got home. Now it fails about 75% of the time. Does anyone have this problem? (I cleared all obstructions from door area).
