2015 Silverado Power Steering Hang Up

[Unkiebunk045]

I have a 2015 LTZ Z71 and sometimes (usually at high speeds in the highway) I turn and the steering wheel gets hung up and I have to straighten the wheel out. If I don't straighten the wheel, the car continues to turn. The dealer couldn't duplicate or pinpoint the issue. Anyone have any ideas

Don't know what's causing it but my 14 LT cc sb does this too. Only at highway speeds on long curves not tight slow curves.
