It turns out that reporting wrong hits is very improbable, even close to impossible, in the triangular set–up. A combination of Bézier clipping and a simple hierarchy of nested bounding volumes offers a reliable and accurate solution to the problem of ray tracing triangular Bézier patches. Citing Literature

"Real" ray tracers tend to do some combination of two things: Placing a bounding hierarchy (e.g. AABBs) on the patch to get a good "initial value" for a numeric root finder. If you do this well, you can avoid the "wrinkle" problem. Tesselating the patch into DDG shells and ray tracing them like polygon meshes.

In ray tracing methods, once the intersection is found, it can be verified that the found uand vare in the [0, 1] interval to keep only the valid intersections. If an implicit surface f(x, y, z) = 0 is used as a rendering primitive, different patches have to be trimmed and connected together to form a composite surface.
