2017 Tahoe Limp Mode due to Steering

[TAMPATAHOE]

Wife went to take the Tahoe to work this morning tried backing out the driveway and she said the Stability control warning message came on and she could hardly turn the steering wheel and the truck would barely move said it felt like E-Brake was on. So she parked it
I got in to put it back in Driveway and everything seemed fine with the exception of Check engine light on. Was able to park it in Driveway rotated the steering with no issues. Only issues leading up to this has been a rattle and small thud in front end when making a right hand turn the thud occurs and the rattle is when I go over bumps at speed. Im thinking the Power steering is starting to go or a ball joint on the front end that is binding up and causing the wheel to lose speed and setting off codes ... Any thoughts???

there is a TSB for power steering to maybe consider

Did you read the code(s)? If so what did they say?

^^^^^x2^^^^^ If you have a code reader, or better yet a bi-directional scanner, it will be very helpful in troubleshooting to get down to the core issue.

Update so after some poking around the Engine light cleared but the AC is no longer working the Compressor sounds like crap even though it is engaging. So im guessing the AC unit had something to do with it. Going to run Diag this week when I get some time so see what code gets pulled
