Drip, drip drip

[Al D-Much]

2020 NX (phase 1) premium plus
I keep getting a small puddle or water / fluid coming off the back box near the rear right tyre (looking at the car from the back)
It's been serviced and has a full bill for good health. 

I'm guessing condensation from somewhere, but everything else seems dry in that area. 
Anyone else have this occurrence? Or does anyone have any idea what the cause is?

Anyone? Anyone?

Is there any evidence of a puddle or dampness in the interior of the car in that spot?

Could it be a leak from the pipe that serves the rear window washer? Maybe the pipe has come loose somewhere?

Just a guess.

Not sure if it's still the case or not but do the exhaust boxes still have a small drain hole in the bottom to release any accumulated condensation (to help prevent corrision) - if so could be from that?

Nope dry as a bone.
The liquid seems to accumulate around the back box seam, then drip.
The hard part is that there is no evidence (that I can see) of anything dripping on to the back box from above.

Possible I guess, can't see anything though. And it's only started happening over the last few months that I have noticed.

As you are still under warranty maybe a visit to Lexus - better to have peace of mind and an explanation than worry about it?

Yes under warranty, also just fresh from a service last month.
The drip was present then too, car got full bill of health

From what you have written I would have thought you would need to describe this to Lexus and have them take a look - they might need you to leave the car with them to investigate it - they don't generally do much investigation during a service - but if you are concerned about it then seems like the best course of action. If they don't find anything amiss, then you have it on record as reported and investigated whilst under warranty should something rear its head in future years (depending on how long you plan to keep the car for).
