First let me say that I love my car, and let me also say that my limited experience with the service center has been great so far. I haven't contacted the SC yet for an appointment so I thought I'd ask here first in case there is something I can do to fix it myself. Both my USB ports are really finicky. 90% of the time when I plug my iPhone cable in to either port it constantly cycles between charging and not charging. Maybe 10% of the time I can plug it in and it will continuously charge the phone. HAs anyone had a similar issue? If so how did you resolve it?
