That doesn't sound too unusual. Does it affect the way the vehicle drives? If so, how? (This is important to know, in order to make suggestions for correcting it).

We are using Black Jaguars for all of them, and only one of them gets a little more hot. It's not that much of a difference.
How difficult would it be to swap the hot motor with one on the other side, and see if the problem follows the motor or stays on the same side.

You haven't said yet, but if the problem is manifesting itself as undesired behavior while driving (and not just an observation made while the bot was on blocks), and if you are unable to identify (or correct) the root cause, you may be able mitigate it by using a gyro (about which more later).
