The new Mustang has brake line lock for doing burn-outs, and launch control. Then they put language like this in the owner's manual:
Page 12: "WHAT IS NOT COVERED UNDER THE NEW VEHICLE LIMITED
WARRANTY? ...misuse of the vehicle, such a driving over curbs, overloading, racing or
using the vehicle as a permanent stationary power source"
It's quite a "Catch 22" as it appears the feature is included to sell cars and then used to void warranty on occasion, if they decide "abuse" is involved.

Rear End Failure Explained!
This video tested and proved my theory of why the rear ends are failing in the C7 Corvette using launch control. If you are using launch control and the car senses that it is on a hill it will put your brakes on and damage your vehicle when you launch it.
WARNING!!!
THIS WILL OCCUR EVEN IF YOU LET LAUNCH CONTROL STABALIZE!!!
This issue can be completely eliminated if Chevy changes it so that the C7 corvette does not apply the breaks when you are in any competitive driving mode or stabilitrack mode.
See video below for a complete explanation!

Very sorry to see this. I know your feeling. I blew a clutch in my C5 at the drags. But I never felt comfortable with the "launch control" in my C7. However, you did what the manual says and if you have a decent dealer you should get them to cover it under warranty. Good luck.

I was able to get out this afternoon, it stopped raining, and make another video. I will post it shortly (need to edit). The theory holds true when in Track mode. RPM is the same for launch mode and the brake holds as well.
