Are there any ADAS sensors integrated in the windshield of my 2018 Maxima?
Need to know more about this as my windshield needs to be replaced.
If there is, will there be the need to calibrate them after installation.

 

I have a 2017 but for the most part our cars are the same but thankfully nothing is integrated in the windshield. I've had to get mine replaced multiple times (damn Arizona rocks and highways) but no recalibration of anything necessary.

I had Safellite do it. They came to my house and had it replaced in like 30 mins.

 

+1 on Safelite. I have used them a couple of time and they did an excellent job.
