Same here. all stock and the description on the sound is spot on and only seems to happen turning left.
Is it reproducible? Might be worthwhile to pull the wheel and closely examine the tire for any signs of rubbing, and also give the wheel well a good inspection for signs of rubbing or any loose plastic. Give all of the plastic liner components a good jostle to check for looseness or play. There are a number of bolts and plastic clips which hold the shroud(s) in place and something may have worked loose or cracked as the plastics get more brittle over time, allowing a rub. If nothing stands out, a go-pro type camera might be useful to get a visual while you try reproducing the sound.
I noticed you're still working with polymers.

I would not take the wheel off to examine this.. It takes away all of the evidence..

Stop the car. Turn the wheel all the way that makes the sound. With or without a jack (and jackstands) look to see the clearance of the tire and the wheel well. Above and below.. You will find something that has been bent in the way of the tire...

I have the same "issue" & it does happen more on LH turns & it's your front air dam scraping/scratching the road.

Apparently our cars have very little torsional flex due to the skateboard battery pack so in those turns the scraping is more likely to happen. Heck my 2013 Prius with lower ground clearance & 135K on its suspension doesn't scrape at a higher vehicle speed where my leaf will scrape every time if I'm going too "fast" as I turn onto my road leading to my house...

Probably not the case, otherwise besides the scraping noise your car would be handling(steering) very oddly......but our '12SL had an unfortunate encounter with a curb, just the tire and from the outside nothing really looked damaged but what happened was the "A" looking thing that supports the lower part of the front wheel got bent, it was basically very thick sheet metal which shocked me! I could have sworn on past cars they were forged steel or much heavier metal. Anyway when I looked closer I noticed the drivers side(the one that hit the curb) the tire was not half way between the front and rear of the wheel well, it was several inches closer to the rear and several inches further from the front. When you'd steer a particular way the tire would rub inside the wheel well. Now in this case the car had some really weird steering but if I were you I'd either look at that lower "A" thing looking for it to be bent or measure the distance from the front and read of the tire to the front and rear of the wheel well and compare sides, on ours the passenger side was dead centered, not so on the drivers.
I ended up taking the car to a local Meineke repair shop where for about $700 they replaced the lower "A" and aligned the car, no more rubbing and runs and steers like a champ now. I can only imagine what the repair work would have cost at my local Nissan dealer :roll:

The 'a shaped thing' sounds like a control arm and they are often made of two pieces of stamped steel welded together around the outside seam to form a hollow part. It is sprung weight so making it as light as possible is good although obviously it needs to be structurally strong enough for the suspension loads.

It could be the control arm, it's the closest thing to the ground(obviously other than the tire) and basically supports the tire itself. I was just shocked to see it bent the way it was and how relatively thin the metal was. Of course if it hadn't had that unfortunate encounter with a curb it would probably have lasted the lifetime of the car. A pothole would have been more an up-down force, hitting the curb while the tire was turned was probably the worst possible angle for the part.
