If it were out of warranty, this would be the route I'd try. However, GM has had me waste my time with 3 fluid changes and after a couple hundred more miles, it's no better as expected. The rear end feels like I have a truck in 4WD on the pavement while turning now. 

Put some in there, what are they going to do? They'll never know you added it.

I wouldn't put the additive in there being still under warranty now if no warranty try it. The rear from what he describes has taken a beating and is greatly reduced the life of the rear if he puts in in there now and if it cures the problem now there going to say there's no problem with rear now and send him on his way now he will have to live with a rear with short life expectancy even though the additive cured it.

What's frustrating is both dealers are essentially saying this is a joke... I have 400 more miles to put on it before GM will even consider replacing it.

Unfortunately the dealers have to go by what GM tells them or they won't get paid for the warranty parts or labor for the repair. Maybe call a lemon law layer and ask or look up the lemon laws in your state.

My vehicle doesn't qualify for lemon law or BBB claim due to its age unfortunately.
