Griding/Banging Noise on Cold Start

Have had a 2013 Camaro LS for about 2 months now. About a month ago I noticed that the belt/engine noise was loud but not really squeaky. Louder than it should be on a brand new car. Then 2 new issues developed. After starting the car after it has been sitting for a couple hours when I accelerate for the first 10 minutes there is a grinding almost pump like noise that happens. Not to soon after, when stopped there is a banging noise that happens in the rear. Have been back to dealer but they consistently say they don't hear anything. This may be my first camaro, but it is not my first car. These sounds are not normal like the dealer said even though they have yet to hear the actual noise I think. People just want to plug a computer in and see what that says now. I have been back to the dealer 3 times and Im going to lose it.

I know its hard to diagnose a problem like this as Im sure it could be anything, but has anyone experienced this before? Thanks!

We apologize for the frustrations that you are currently experiencing. If you would like, I can set up a case with GM customer service to research the concern a little more in depth. Please provide me with your first and last name, address, phone number, VIN, mileage, and involved dealership in a PM.

We look forward to your reply.
