"I thought i was hearing it at higher RPMS, but that was just engine/induction sounds I believe most cars have at higher speeds.

I dealt directly with my technician and sailman. I took one for a test drive without either present. THe 2011 i drove sounded the same, that was my opinion. But i never told them that since i was/still expecting an explaination of the present sounds.

Supposively, there is a ticket into GM with the issue.[/QUOTE]


Yup, sounds like the GM corporate directive of "give the customer a "like" vehicle to drive" response. They (General Motors and the Sales Managers) appear to use that approach with widespread problems such as the AFM and six speed transmission complaints so many newer owners seem to have.

Did they ever give you an explanation?
