Where to begin-
Bent pushrods,check engine light that was basically said to just not worry about it because they couldn’t replicate it and tonight…the icing on the cake.

Anyone dealt with this yet?

Was turning across a very busy road in my town and the whole thing locked up. I was able to turn the truck off, then back on and as I turned into the gas station it locked up again but this time there was no movement…ripped complete off the ball joint, drive axle(?). 2021 with 20k miles on it and I’ve had more issues with this brand new truck than any vehicle I’ve ever owned combined.

That's what happens when you lift it without putting upper control arms on it meant for lifted trucks. The ball joint angle is too extreme and causes excessive stress on the ball joint and leads to failure which is what you experienced.
 
So GM is basically selling us a product meant to fail?
 
This will be the 5th time I’ve had it at the dealership..push rods,lifters, random engine misfires, now this…my TB days are getting numbered

If you leveled/lifted the front beyond what it is from the factory 2” lift, this can be the result. This is why everyone states to change the upper control arms with a Ready Lift, Zone, Rough Country, Icon, etc… to correct the geometry for the additional lift so the ball joint doesn’t break.

If you never lifted it and your ball joint broke, then it was bad luck.
 
So true on all this. Being a mechanical engineer it is all about geometry. That is is why when I bit the bullet on the 6" BDS lift I knew I would be fine. Sorry about your issue. That sucks.

You can see the spacer below the strut on the bottom A arm.
