Has anyone encountered their S/C suddenly getting a little louder. Even on a idle you can hear the whining.....which is so not a trait of the Z. Only 6700kms on my 2019 and just out of the blue in oct when I put away it started getting louder. I've read lots of people on line saying this has happened but not any on any warranty or any getting fixed or for that matter an answer from GM as per why.
