It is extremely unlikely to be a problem with your game. Modern video games are not prone to errors like this would have been.

Did you status it? Wild Pokémon can’t call for help if they have any major status condition. If not, it’s very likely that you’re just getting bad RNG.

Have you tried using adrenaline orbs? Have you tried lowering its HP to red?

Thank you for reminding me of Adrenaline Orbs. In USUM (but not regular SM), a Pokémon won't call for help after one successful call unless you use an Adrenaline Orb.

Maybe it’s just a really unlucky Zorua.

Answer 1

In Pokémon Ultra Sun and Ultra Moon, a wild Pokémon will only call one ally per battle, unless the player uses an Adrenaline Orb. Wild Pokémon that have a non-volatile status condition or are in the semi-invulnerable turn of a move such as Dig will not attempt to call for allies.
The call rate is multiplied by a factor of 5 if the calling Pokémon's remaining HP is below 20% (i.e. the HP bar is red).
The call rate is multiplied by a factor of 2 if an Adrenaline Orb has been used in the battle. The Adrenaline Orb can only be used once per battle and will fail if used repeatedly (wasting a turn without being consumed).
