Drove my wife's NX earlier this week and noticed a random, somewhat constant ticking coming from around the drivers side window/door. Wasn't able to localize exactly where while on the road. I rolled the windows down/up, opened/closed the door, turned down the AC but to no avail. The ticking occurred both while driving and while stopped at a stop light.

Anyone else notice something like this?

 

I had the same experience and at some point came to the conclusion that the sound I was hearing was the ventilated seats. There is air flow and the sound seems to travel around the seat bottom, door and headrest.

 

A long shot, but since sound travels in weird ways… if you have the center console wireless phone charger with a phone on it make sure it’s not that. It makes random noise like a CD changing tracks while it’s trying to “mate” with the phone.

 

This I can confirm. It's not an annoying sound to me but I did wonder why the wireless charger made that clicking sound🤣

 

One thing that could be causing the noise is that apparently Lexus built cooling into the wireless charger, so what you could be hearing is the fan in the cooler

 

I am having the same issue, but it is on the passenger door. I narrowed it down to the speaker grill on my Mark Levinson. When I hear the ticking, I push the grill and the sound goes away. Not sure what it is because nothing is loose.
