whining noise

[KurtMcMouth]

All,

 

I've had my 05 1500HD 6.0L for about a week now. When leaving for work in the morning, a whining noise comes from the engine. It sounds a lot like a pwer steering pump going bad. The more throttle I give it, the louder the sound becomes. The sound slowly begins to go away and is gone in 20-30 minutes. The dealer is trying to tell me this is normal.

 

Has anyone else had this experience?
