The rear motor, the rear wheel, is fried. There is a temperature sensor and it was sending out a false reading, and the motor totally cooked. Due to holidays no replacement can be even be even shipped until Tuesday. All day was spent attempting to repair. With consultation with the factory a last-ditch effort to repair will hopefully take place tomorrow, and then if that doesn't work as it probably will not, there will be an attempt to disable the motor because even though failed there is an interaction between the wiring and the magnets that creates a resistance situation that immobilizes the vehicle which otherwise could run on the second motor.
