Well I guess I should be glad I'm not the only one experience mysterious sounds when turning the vehicle to the left. Please PM me if you would like for me to post a recording of "knocking" for anyone here to listen as the sound is very obvious, but not loud, while also consistent everytime I make a u-turn to the left. It's not intermittent or hard to hear.
As for downtime, please do take it in, and ask that a Nissan tech sits with you, and reproduce the sound so there is verification it exists. NIssan should NOT prevent you from taking the vehicle back home while they "move the issue" up their chain. Hopefully, this data can result in a TSB that will make this fix much faster.
Note that my 18 MY SV was a different issue, which was a creaking from the cross bar bolts.

Update on the 18 MY SL: Dealership informed me they are flying in a senior regional Nissan tech next week to listen for himself the "tocking / knocking" sound coming from the left side. Existing TSBs, loose nuts, axles, ruled out by local and regional techs as root cause. Gonna be interesting. Still racking up miles on an otherwise great car (now nearing 8,500 miles 6 months into ownership of this unit).
I'm curious what comes of this. I have also experienced a strange sound when turning left into driveways or shopping centers. It is almost like a clunk and grind type of sound that I can feel vibrating in the chassis. It doesn't happen all the time but it is loud enough that my wife has noticed it when it does. I haven't cared enough to bring it in for service on this as I figured it would be hard to reproduce and I really don't want to deal with the downtime.
For what it’s worth, mine also does this. It doesn’t seem too alarming, though it is disappointing in a brand new car. I’ve been meaning to take it in.
