First thing would to do would be to tell us where in North America the missing streets are located. Maybe even provide permalink from the Waze Map Editor or Google Maps of where the subdivision is.
With that information we can start looking at updating the map.
I think I have fixed the map up. Unfortunately we are currently in a delay for updating the app due to some technical issue that Waze is having. Hopefully the fix I have made will reach the app in the next few days, if it has not updated by next week let us know and we can tell you if the app has been updated or not.
I added most of the house numbers to the street as well. Hopefully this will help everyone. I would suggest that once the app gets updated, you delete any previous search results you may have so that you can get a fresh search.
