We ran into a similar issue yesterday, but the source of the issue was easy to identify and resolve.
We were dropping the voltage on our battery to <8.5v every time we did a point turn/pivot. Driving straight kept the battery above 12v. This was obviously a scrub issue.

We are running a typical WCD with 8" pneumatic wheels, thus the scrub should not have been too great, but it was. Why???

During early practice session, the students felt it was beneficial to lower the pressure in the center tires to help gain traction going over the Rock Wall.

Lowering the pressure to ~0psi basically renders a WCD to be just a 4 wheel tank steer.

We re-inflated the center tires and our voltage drop on point turns returned to normal, around 11.5v.

With the additional practice time we had put in, our driver also had figured out how to transition the Rock Wall without the need to have "high traction/ low pressure" center tires.


Now what bothers me with the OP's issue is how two motors on the same transmission could have such a huge temperature difference.
Are you controlling the ESC's via "Y" cables, or discrete PWM outputs from the RoboRio?
