1. before you complain get educated on what kind of warrenty you have
2. groaning on h2 steering is not unusal (not rack and pinion man it's a truck)
3. no obligation to give you a loaner peroid.
4. They should have cleaned up the contacts as a courtsey but if yo were a dick ???

All in all you bought a used truck and if it is not a GMPP warrenty you may not have much of a warrenty. Most are not bumper to bumper so the wind noise is your problem. This is why I NEVER buy used cars.
