Throttle wire/serpentine belt problem

My 1300 miles new Z06 died in King City on the 3rd. I was pulling onto the freeway at moderate acceleration when all the chimes and lights and error codes on the dash started flashing. Speed was limited to 30mph. I took it to the dealer there and got a rental to get home. Now the dealer tells me it pulled a "throttle wire" into the serpentine belt tearing up both. The dealer's mechanic thought it might have been because of aggressive driving. Has anyone heard of this problem? Is there anything else that needs to be tied down in the engine bay? The dealer did assure me they will tie the wire down so it can't happen again. It was pretty shocking to suddenly be trying to get out of the way of a semi doing 65 and only be able to go 30. Has taken the edge off my trust of this car.
