Drivetrain Issue

The aforementioned insights provided are probably your most likely bets, but also check to make sure that your burning hot motors have intact o-rings around the ends of their casings (places where the black painted portion of the CIM meets it's two cast endcaps).

Missing or damaged o-rings can allow fine particlates into the interior of your motor and degrate or destroy the brushes in your motor. From there, it's possible that you rmotor could be partially or completely shorted out.

Also, have your programmers check your code, a typo could be the cause of all of that.

what kind of transmissions are you using. We had custom one and on one side the output shaft got bent and it added a lot of binding problems. If you using the kit of parts ones then check the pwms we had lot of problems with that.
