2017 E300 Outside Temp Sensor Not Working

Yesterday my outside temperature display starting acting up.....Said 69 degrees when it was actually 80. Had same issue on my 2013 and 14. The outside sensor was located in the lower driver side front grill all the way to the right of the grill. It used to need to be pushed into place sometimes and worked after that. I can't find the sensor on my 2017 E300. So many sensors for the parking program but don't see the temp sensor.
Anyone else having this issue or know where the sensor is? Mine is working intermittently now and would like to check it out myself if I can.
Appreciate any info that can be provided.

Checked the entire grill today but no sign of the sensor.....Only sensors I see are the parking sensors. Appreciate any one else who might have an idea where the temp sensor is.before I head to the dealer.

It's a brand new car .... I agree talk to your dealer ... once you find the sensor what will you do?

most likely it just needs recalibration

If it woks like past models it sometimes just needs to be pushed into place a bit...A car wash can even cause the past ones to get out of line...Actually appears to be working now but like to know for the future.

Why mess with a warranty item? You break it, you bought it
