That is troublesome to hear there are also problems with the 2017 MY.

Can you tell us the build date of your car ?

I've had something similar with my F150s (2 of the same generation, a 2011 and 2014). Drivetrain clunk after coming to a stop and then hitting the gas. Factory said that is normal for that vehicle. Um, OK, normal due to an engineering or production issue, but not GOOD.

Sometimes if an issue is not a hard failure they make us work for it. Sigh.

2017 Corvette Warble
 

I purchased a 2017 in January with a build date of 11/16. Starting hearing the noise at 1500 RPM, around 150 miles. I have read through the post and was just wondering what would be the recommended path or starting point for getting the issue resolved.

If we didn't have the Warble noise or the Torque Converter failures to talk about, we would have very little to talk about on the forum. Too bad GM will not stop us from discussing these subjects. :ack:

Take into your dealer and have them take a ride with U and make sure they hear and acknowledge the noise. Share the cause as you know it to be from our experience on this forum post. Insist they call tech support and Eng for the Diff. replacement. That is the starting point and proceed through the process until you get a fix. That may mean going up the food chain at your dealer and GM. Good luck

Warble Sound
 

Thanks for the advice, I will start the process

After listening to Strakes You Tube video and Darrin Edwards' videos I have to say the the sound I'm hearing is more like one of the Darrin Edwards' videos.

Does that qualify for this new ATF fluid TSB ?

Video
 

They are both the same sound. Try listening again. Remember the rpm is around 1500 usually in high geAr. But I can get mine to warble in 3rd gear on M using the paddles and rpm at 3000.

Yeah it sounded far fetch to me. I've contacted Jeff with GM and see what he can do for me now to get it fixed . I have my fingers crossed .

I can get mine to do it in 2nd up either in M or auto the hotter it gets the worse it is

He's da man.

Ask the dealer to put that in writing...date and sign .. send copy to GM
via certfied mail ..ask for responce within 14 buisness days...then call an attorney ..
Sorry for your headache ..but .. it is a GM ...the only good thing about the answer ..is ...they did not just start ripping the car apart without knowing how to correct ..

I have been dealing with this noise for over 6 months now. I heard it really bad on the first drive home that night I purchased it from the dealer and just kept it under the rug.


Well as I am driving the car more I am beyond annoyed at it. I will begin to pursue the matter with GM and my local dealer.


I have an appointment on Tuesday evening to have the shop foreman to ride along with me to replicate the sound.


I will be getting a better video tomorrow with hopefully less ambient noise in the area.


Who are those that have had this problem "FIXED" May you speak up so I can notify my dealer exactly what needs to be done.


Thank you

he will probably tell you to put your seatbelt on or whatever it is to stop the dinging.

You've definitely got the warble. I was one of the first ones to get a new diff. That was over 600 miles ago and the fix is still good. I have a contact in GM who, when I talked to him last, said there were two ways to go. One was to have your service person call the Technical Service Center and/or two, there was a post awhile back from Customer Service to go through them. If it would be worthwhile, have your service guy call me and I'll talk to him and explain the whole mess to him. Mine was one of the first cars tested for the diff fix. If he wants, I'll ask my contact to call him if the Tech Assist Center or CS doesn't work out.

I had turned the speed warning monitor on the car before I left. I have been driving the car more learning all the things it has. I guess because I have navigation and Onstar it knows the speed limits of the roads I am on and it alerts you that you are driving over the speed limit.

Highplains,


Thank you a lot for the information. Can you PM your number? I do not know how competent my dealer is honestly. I had a great experience purchasing the car through them, but their service side I do not know as I haven't even had my first oil change yet. I had a software update done which was a simple fix and had no issues with them. They are a decent size Chevrolet dealership that usually stocks around 30 corvettes. So hopefully that have a tech who is familiar with these cars.

After listening to the video/audio U definitely have the WARBLE. Take the dealership Serv. Manager a ride and ensure they hear and acknowledge the noise. Follow Highplains advice, if anybody has the ear of GM Eng. it is him. Good luck and keep us posted.

Hope you can get resolution quickly KKC7.
