Perhaps it may not be a bug.

Because, when my character perpetrated a crime in Riften, all Dawnguard members turned hostile. After that, my character expiating by the bribery has no longer been turned hostile by Dawnguard members.

If it is a bug, did you tried Unofficial Skyrim Patch and Unofficial Dawnguard Patch? (For PC use only)

If Dragonborn had the vampire blood and joined Dawnguard faction, it is not enough reason to be hostile. If your character is vampire, your character not yet start Dawnguard quests, your character can not start Dawnguard quests and you want your character to join Dawnguard, your character could meet Aela the Huntress, could replace the vampire blood by the werewolf blood and Dawnguard members would not turn hostile.
