Today I took my 2011 LS Camaro back to the dealer for the 4th time due to the rearend making a roaring noise when I make turns, either left or right. Each time they have changed the rearend oil.. The car had 8500 miles now,, I dont want to keep doing this ever 2000 miles,, What is the problem ,, Is Chevrolet aware of this problem??

 

You need to make more noise at the dealership, or go over its head and deal with a GM rep. There should be a number to call in your owner manual.
