Yes. I had the same issue on my wife's QX60...although mine was done under the CPO warranty. Who replaced the windshield? Perhaps contact them first.

Whomever replaced the windscreen may have done it incorrectly or didn't bother to replace that unit. The sensor is filled with a kind of liquid gel that cannot be reused.
If you replace your windscreen, the unit itself CAN be re-attached but ONLY if the old reservoir is emptied, cleaned thoroughly, and refilled with new fluid. It is a bit tricky to install as the sensor must be placed against the surface of the glass with NO air bubbles. There is a cure time that must pass before you attach to the glass. Here is a video that should help you fix it. I recommend buying the larger kit because I botched the first attempt. The worst part is cleaning the surface of the windscreen and the surface of the sensor. If you muck up, you have to re-clean everything and start over. This new product appears to be tons better than what was available 3 years ago when I replaced mine.

I was told by a glass installer that Nissan rain sensors never seemed to work correctly after a windshield replacement. They usually just plan on replacing them.

At this point, I've only experienced this one time, but it's something I've kept in mind for future considerations.

Here's a snippet regarding my experience with my 08 M:

I think I can finally lay this to rest.

The gent showed up with a new OEM sensor. Part # 28536-3NF7A
It came with some gel already on it, and when installed it works just as I remember (...I think. I never thought to test and carefully watch it before the windshield got replaced). It's sensitive enough with the new sensor and glass that putting one's hand over the sensor will cause the wipers to swipe.

He told me that his boss said that they've had to replace sensors for the Nissans they've replaced windshields on. I can't tell you why, because I can vouch that all he did was unplug and carefully remove the sensor. :gotme

Oh well, now you know what to look out for.
