the uconnect syncing issue is a known problem on all 13/14 darts, chrysler has requested dealers not replace the hands free module until they figure out the problem, at which time they will issue either an RRT or Recall to fix the issue.
Welcome from the PNW aka WA. Thanks for joining us. I hope you are able to get your uconnect issue resolved. The Dart is a complicated car, at least it is to me. Took me forever to figure out that my phone volume effected the volume of the bluetooth connection. I kept trying to adjust the volume on my car and couldn't get it right. Had a WTF moment but I'm better now. Enjoy the site.
