Take it in, the more cars are reported with this issue is proof there is a problem. Don't want to offend but don't wait for others to do the heavy lifting in hopes for a TSB, take it in and push for a fix. Highplaines suggested his got worse with miles and so did mine. If it's the ring and pinio it will only get worse. If GM approves you for a new differential you want have to take your car in until the diff. is in so limited wait time for repair. Good luck

How?
Took car in morning of 2/23/17, they replaced the differential, got it back first thing this morning.
No more warble, only drove it about 10 miles .
Heard a faint sound around 1500 rpm when it was cold, but nothing like the dreaded "warble".
I'll keep the thread posted, as I put on miles .

I got a call from someone at GM who left a message saying he was in the "Executive Office". He left a phone number and a case number. My dealer has never heard of this issue so I am hoping the folks from GM can educate them before I take it in for diagnosis. At this point in time the noise is not very loud and I am tempted to wait it out until hopefully a TSB is issued and the parts are readily available. When my TC and fuel pump were replaced the car sat on a lift for a couple weeks waiting on authorization and parts. I am finding it hard to reproduce the sound so I am tempted to wait and see if gets louder. Have you other warblers found that the noise gets louder and more frequent with more miles? My lemon law opportunity in MD expires at 24 months which will be in July of this year. Advice? Thanks.

i took delivery of a 2016, corvette stingray (base), with auto. Trans., on may 2, 2016. It warbled at 1500 r.p.m., from day #1, until wednesday, february 22, 2017, when a new rear differential, from non-stock production, was installed by my chevrolet dealership, along with new "f-carrier" and fluid. I have repeatedly tried to make my corvette warble, at all r.p.m.'s, including the culprit 1500 r.p.m., and the vehicle is totally silent. No more warble, at any r.p.m.! I could not be more pleased, as there is a noticeable difference in the vehicle's operating performance. My corvette is slippery smooth through all r.p.m.'s and 100% silent! My recommendation to fellow '15, '16, & '17 warblers, with base corvette stingrays and auto. Trans., is to have your local dealership contact chevrolet quality control and request assistance with having a new, non-stock, rear end differential provided to you / your dealership, for installation. My understanding is that the 5 - 10 customers prior to me are also completely satisfied with their new, non-stock, rear differentials.
I love my corvette! It is a pleasure to drive a flawless vehicle, once again.

Interesting. I had not noticed mine until recently when I turned down the radio and listened carefully. If it stays the same, I'm not sure I would demand a new differential. Not sure what I should do.

I'm just wondering if those who have has this sound have ever had the fluid checked in the rear? Mine was checked on delivery & it was 28 oz low!
I know they had this prob a yr or so back, but my tech says they're STILL coming in light from the factory, and questioning if this may be the root cause of the rear diff failing?

Didn't have mine checked that soon. Had it checked at approx. 1500 miles, and it was OK. That was also before I knew what to call the sound coming from the car.

My understanding from a contact at GM in Detroit is that the problem came from a problem with the ring and pinion mating. The mechanic who did mine as well as the GM field engineer that was there to test my car said that they could easily see the uneven wear when they took off the access plate on the diff. That and metal powder in the oil from the wear.
That's good info to know. If they give me any grief surely I can convince them to remove the access plate.
