My 2018 GS had a clicking sound when I made a slow sharp turn (eg: backing out of a driveway). The dealer corrected, said it was something to do with the brakes. I have the Z07 package, so it might have been related specifically to that brake (Carbon Ceramic) setup.
Actual text from the repair order:
" NEC to resurface both front rotor and rotor to wheel surfaces"
My c7 stingray had the same issue of ticking or clicking when slow turning backing out of a space or turning at very low speeds. Very faint sound, but would hear it daily in the parking garage at work when backing out and pulling forward. Did some other forum research and talked to dealership and there is a Chevy service bulletin on this issue. It has nothing to do with the brakes.
The noise is caused by corrosion / spacing between the wheel hub and the wheels. Remedy was to remove front wheels and clean and lubricate contact surfaces between wheel and connecting plate. And then the wheel lug nuts are tightened to pretty extreme torque specs. I was alittle skeptical at first, but it did solve the issue 100%
