DRV8307: Motor not starting up at -15C

Tool/software:

I have a design that functions well at temperatures -10C or higher. However, I have test that consistently fails on multiple samples at -15C. 

The motor simply does not start up, and the motor driver faults out. I can raise the temperature, power cycle, and the motor driver will operate again.

Can TI evaluate the schematic attached, for any risks at low temperature. Is this an issue that you have seen before?

For the test, the power supply is 13.5V.
