In brief: No and yes
Metformin does not lower vitamin d, but people with diabetes and people who are overweight are at increased risk if vitamin d deficiency.

In brief: Low B12 possible
Metformin can cause the body to become depleted of vitamin b12.
Often, an non-prescription supplement can correct this, but it is always a good idea to get a level checked to see if you need a supplement before you start taking one.
