Just after I start it. There is a whining noise under the hood. Now, this noise only lasts a second or two and is louder when it's cold.
Not sure if it's the Power Steering pump or a belt. Anyone have any ideas? On my last visit to the dealer they said that this problem is common with the 8.1 liter and that GM is looking into it.
