For the bump noise in the right front, Most likley is the Strut Mount. However after that is replaced(at the Chev dealer) noise is back in about 100 miles. Poor quality part from China. Also the hanger at the Catalitic converter, this is a known rattle. Also sounds like you may have a weak motor mount causing the vibration noise.
I have been a GM customer since 1947, Think this is my kast GM. Too much China low quality parts used in GM Vehicles.
Thank you. I will have to ask about this one at the dealer. Before I do, I might go to a trusted mechanic my uncle (driving school business) uses to see if he can help me diagnose before I take it in.
I can understand that the motor mount will help the vibration. What I don't understand is why the engine is vibrating that much anyway. I mean I put my hand on the engine cover and it's like a massage chair.

Hi Michelle and others,
Here is an update.
I mentioned all the issues above (windshield noise, popping noise, front end clunking, and engine idle) and here is what happened:
Windshield noise they figured is the passenger side mirror deflecting wind-noise. I thought otherwise because it seems to be in a specific area, especially in the dryers at a car wash.
The popping noise when reversing was a wheel bearing gone bad. Replaced under warranty. Noise is gone. Thanks to ChevyMalibuForum, plus this thread, plus the search function, I already had the thought that it was the wheel bearing.
They were unable to hear/determine the noise for the clunking. It seemed to be quieter when I first got it back (psychosomatic??), but now I can hear it loud as ever. "Unable to verify complaint." Hence why I may take it to a trusted mechanic first to see about a diagnosis so I can direct the service at the dealership.
The rough engine idle... They checked codes... nothing. Checked engine updates... nothing. "Unable to verify complaint." I still think it may be a spark plug, but again I may ask the mechanic to help me look at this. I don't want to do it myself for fear of messing something up I shouldn't. Oh, and the oil change seemed to help it a little bit - but it still vibrates a little too much for a 2011 V6. Heck, my girlfriends 99 Ford Taurus V6 does not vibrate nearly as much... Someone did mention (above) about a weak motor mount. I may have to ask about this one too. Maybe the dealer or a trusted mechanic.
I just wish front end noises were 1, easier to describe, and 2 easier to fix
! But I know that the noise can come from anything.
Thanks for the response Michelle and hjlint.
I was supposed to be getting notifications on this thread, but I see that it wasn't working properly. I will have to check back more often obviously!
