C12 voltage rating too low
Using my capacitor rating script on the circuit netlist, I found that there is a 10V part used for C12 but we're applying 12V on it - a higher rated part should be selected.
Optionally, you might consider also swapping the 16V C10 and C11 caps (still on the 12V rail) with the 50V 0603 part that's used in other places, as 75% of the rated voltage is still not optimal for component lifetime.
