It's not the fault of launch control, it's a problem with the output shaft of cars built in the mid 16thousands.

GM is aware of the problem and apparently re-routed some cars to Detroit to get fixed after build but before delivery. Hopefully they get you a new transmission soon.
This makes #4 I believe, all built very close to each other.
