Air leak around mirrors and front doors

2012 tacoma dbl cab .has anyone else having this problem? When driving down interstate. Loud whistling coming from the front corner near where the black triangle plastic piece is.
Seems to do it more going around curves when it's windy. Very loud.

 

I've heard here that the weather strip at the hood/latch is a problem for some trucks.

Try this, use blue tape and seal the front hood/grill seam and take it for a ride. If that whistle persists, then it may be your mirror sail.

I'm sure it's not the hood area it only does it sometimes .it is coming from either the windshield or door where the mirrors are mounted
