I'm trying to be a little bit cryptic here but it has to do with emissions and unlocking your ECM.
I never had steering problems because I bulletproofed everything at about 2,000 mi. Your dealer is unlikely to cover your pitman arm. It's a wear and tear item similar to your ball joints and CV axles. They are also unlikely to replace your AC compressor unless you're experiencing actual AC problems. I've had the a distinct squeal type noise in my suburban when the AC system kicks on and off since brand new. I still have the original compressor coming up to 300,000, mi.
In regard to that video you uploaded, I think it's a software issue, not a module issue and it probably started after a specific update. I have never updated my truck since brand new. As a matter of fact, I disabled everything the moment I got home from the dealership
