HTC Rezound (Verizon) will not sync with Google Contacts. Gmail and Calendar sync fine.
If you continue to have issues, perhaps deleting the Google account off your phone and re-adding it would help.
Is this something that just started happening or is this a new phone? If the contacts are saved to the phone as phone contacts they won't sync with Google... You will have to export them from either the phone or your backup assistant account and import them into your google account.
