I found this report on another forum and found it to be pretty troubling.
"Just got the car back on Friday and almost died on Saturday...
One day with my new c7 and after I installed the targa top I got a broken windshield , just got her back Friday and yesterday while on track mode selection with rev matching on the car while running at 40 miles on a turn it went hey wire and locked all 4 wheels and jumped to a dead stop, a miracle the cars behind me did not crash on me, trans made horrific noise and start smelling.....also other electronic problems
690 miles on the C7 Z51"
There is not much in the way of details here, so we have to work with what is written. I cannot believe that this problem has anything to do with the braking system, but in light of other Z-51's having E-diff issues (low or no diff lubricant) I believe that the e-diff is the culprit in what happened to this person's car. I have heard where GM has issued a TSB for dealers to check fluid level in Z-51 e-diff units but do not know if this is a rumor or is factual? Anybody have any details about this issue, or any thoughts about it?
