Whine from back end (plus poll)

[improviz]

Wow, exactly same as what mine told me....which I found out in researching this is the same reaction GM gave to CTS owners years ago who were having the same issue.

Well... Dealer told me it all sounding normal back there - Only thing left to do is get a ride in another C8 to figure out what "Normal" is.

Tough to tell. Have heard the "whine" if I listen closely. Sounds like normal mechanics. Car works great!

I will be attending the Spring Mountain school in March and will compare the sound in the C8 there to my C8 to see if theirs has the same whine as mine. I’ll post an update upon my return from the school.

Much appreciated - I was thinking of going to that school too, but couldn't work it out... All of us who have this will be very eager to hear what you find - Really getting sick of listening to it!

"Normal"
The canned reply of every LAZY service writer on the planet

I mentioned the whine in my C8 to the local dealer tech. His notes on my paperwork said he drove it for over an hour and never heard it. It just so happens I had recorded my odometer when I dropped off the C8. When I picked up the car, the miles on the odometer had not changed! Time for a new dealer!

would contact the owner and let him know and secondly, contact GM. That is outrageous and unethical conduct on their part.

If you leave the PDR on all the time or when in valet mode you can go back and show the dealer GM .

I will follow up with the dealer when I return from Spring Mountain and after driving another C8. I have a 1LT, so no PDR.
