It's 1200 rpm on the TSB. My particular ZL rattles all the way past 3000 rpm. Dealer still says that it is normal. I will bring the car to Cadillac as soon as Chevy finishes all the other warranty issues.
To OP, maybe try Cadillac dealer next time. They probably won't scratch the F^*% out of your car like chevy dealers like to do.
