Brake will not unlock when below freezing. No problems in summer. Can there be water freezing in a hydraulic line going to the brake assembly? When locked and running for a while (up to 2 hours) sometimes will become free with a loud bang, sounding like a pin or something is breaking. After using the parking brake will engage normally.
No issues when machine is in a warm building.

Check your travel lock solenoid, inspect the wiring on the solenoid
The brakes lock and unlock fine in above freezing temperatures.
The right brake will not unlock in freezing temperatures. Can water be in the line on the right side at the end of the hydraulic circuit at the brake?
Or something in the brake assembly?

I would call up John deere and ask them if they had any recalls with drive motors.

Here at my dealership where I work we had an issue with break failure on the ssv75.

We replace the entire motor but its just a bad oring that failed inside the motor
