I have clicking and ESC (stability control) light activating on one particular off ramp that's fairly tight. So I'm turning right, but really not driving aggressively or pulling significant Gs. I don't feel any intervention like braking. Anyone else had this gremlin? (I also have an airbag light on so good thing my expectations were low thanks to this forum)

It's working normally. Drive it hard on a loose surface i.e accelerate on wet, snow, or ice the ESC / TSC light will flash momentarily until traction is regained, then it'll stop flashing.
This is not normal. I'm driving at very mundane speeds in a dry off ramp. Equal G going leftward does not activate esc
Could this stored malfunction have anything to do with it?

I had a similar experience with my AWD ID.4. Drove it for the first time on a winding highway (CA HWY 17 between Santa Cruz and San Jose). On several occasions, the ESC started intervening, although the road was dry and I was going a moderate 45-50MPH on not-very-tight curves. I think it is also related to road surface. Only happened on sections that had relatively rough asphalt pavement. Never happens to me on my other cars I have driven down this road.
Glad I'm not alone. It's tricky to see the light activating because the angle of steering wheel blocks it; I feel gentle brake pulsation /intervention and then move my head to see the light. I'm afraid to tell the dealer because they may mess things up trying to fix what is a minor inconvenience, and also due to potential wait time given current parts shortages.

Yeah, I think I would try go get more experience with it before going to the dealership. I will post here if I can figure out better what exactly triggers this.
I drove up to Big Bear today and had the same experience on CA Hwy 330/18. I have it happen to be on Interchanges in the past but didn't bother much as it was one-off incidents. Today it was on multiple turns. I didn't pay attention if it only happened turning right only (the interchange I know it happens is a 270° right turn). I did notice it only happens if I was accelerating and several times while ACC was engaged (which would cause ACC to turn off). The car felt like it was pulsating. I had the car in comfort, didn't try Sport or Traction which would have the front motor engaged at all times.
Does everyone who has this issue have AWD models? It feels like the computers have a hard time with the front motor and the speed difference between the two tires in turns. With the two tires turning different speeds, the car interprets as a loss of traction even though there is not one.

ID.4 utilizes open differential(s) for either the RWD or AWD. The TCS, ESC, EBD, EDL etc., are ABS brake-based that use 4-channel ABS sensors to read the speed differential between the pair wheels and front to rear axles.
Unlike the older, much simpler ABS System has the teeth cast on the hub, rotor, or a separate tooth-ring. The new-gen. ABS-based TCS, ESC, EBD, EDL etc., requires more precise differential speeds in each wheel and front to rear axle. This new-gen. ABS System has magnetic strips radially incorporated inside the wheel bearing on the outboard side of each wheel. Therefore, when the slightest wheel slip is detected regardless of the road condition, it generates the ESC or TCS light to blink momentarily until traction is regained. If the ESC or TCS light stays on, then there's a problem with the system. A code or codes will be generated. The use of an OBD II scanner will decode the trouble code(s).

It lights up momentarily, it always stops as soon as you straighten the wheel.

Just thinking out loud here, have you verified tire pressures? It might be enough just to throw off the ESC rotation readings under lateral load. It’s also quick and free to verify.
Yes, verified with digital gauge
Stock tires
i will take a video when I return from vacation to show just how slow I am going and still having this ESC intervention.

This historical information if possible recreate with technician driving with you should be taken to service and have engineering department figure out what changes are needed for fine tuning ESC parameters ....if all other required checks are ok...it will be just software parameters adjustments. ..thanks for posting historical data pulled by obdeleven.
I have vcds
i could dig around but I am assuming there is a way to pull up all four wheelspeeds at once?

Yes.
This is not a particularly useful video other than to show slow speed. Each flash is accompanied by gentle application of brakes. I couldn't get the road in the same viewing area as the binnacle, but you'll have to trust me it's a dry, standard radius onramp.
A new observation: This seems to have a lot to do with the angle of the steering wheel/road curvature, not the G-forces. I've tested ramps and twisty roads with less curvature (greater radius) at high speed and traction control does not activate inappropriately. Not a surprising observation since there isn't loss of traction when this light is going off, and shorter radius would increase the [expected] minute differences in wheel speed that the car is presumably responding to.
Next up: will try same offramps in ESC sport mode (not to be confused with sport driving mode; esc sport mode is buried in menus and brings up "esc off" warning when you select it, although we all know it's not off) , then eventually get around to logging some measuring blocks with VCDS to try to capture what the car is seeing that's leading to inappropriate ESC
