I have a 2013 SHO with 11k miles and every now and then while making a left turn then applying gas it makes a loud knock sound. I think it might be the AWD or traction control adjusting. Curious to see if anyone heard the same sound or maybe explain this. Tks!

not sure what it could be. But its not the AWD or traction control adjusting.

I've never heard it, but tie rod ends and loose stabilizer bars have been associated with a "clunk" in other threads here.
I agree with crash.

... sounds like something loose (Lug nuts are tight?)... or in the UJs or CVJs

It's only made the sound twice and it seems to happen when the car is finding the right gear while turning but i don't think it has anything to do with suspension I think it's the tranny which seems to be shifting fine. Not too worried right now but if it keeps doing it I will bring it in and have it checked.

I get that once in a while. Usually at low speeds and last for a couple of seconds when turning left.

The closest thing I can find is TSB 10-22-4 that might fit these symptoms.  I cannot find the TSB itself, as the one site that had it as a PDF has gone away.  Maybe someone on here has a copy or access to the TSBs?

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

I've got this occasionally...I don't mind it as long as it something attempting to destroy itself.
