  In this work we shall obtain sufficient conditions for the appearance of
singularities in gravitational theories which propagate an extra vector degree
of freedom, based on the known relaxations of the singularity theorems. We
study the cases of a general Proca field and a vector theory with stable
self-derivative interactions. In this study we show several cases of
singularities that usually would be considered as potentially singularity-free,
since they violate the usual point-like energy conditions.
