I've had issues with mine 2017 Silverado 2500 after having to replace the pitman arm, and I end up Nick in the wiring to my variables assist steering component and that's cause my service power steering system light came on unfortunately you cannot just buy that one small component GM wants you to buy the hole dang gearbox $400 might as well say. And I called BS on the dealership not being able to program it because I use the same software as they do and I have no problem reprogramming any module on my truck including the steering power steering control module.
