When I driving against the wind or higher than 40 mph hear a rattling noise coming from the front, I have checked for any loose components or cables, seems to be related to the speed of the air in front of the car.

My next step is to get a couple of ramps and see if there is something loose under the car, but before spending the money wanted to know if similar issue had affected anyone.

I do have a volt shield and its safely attached.

Thanks,

If you can't find the loose peace by inspecting the car on the ramps, I would be tempted to have a couple friends drive in front of me on a quiet road at around 50 mph. Have the passenger in the car in front of you take a look at your car and see if there is any noticeable movement of any parts. My first thought was the air dam but it sounds like you checked that already.
Rattles can be tough to nail down. I had a RAV4 years ago and it had a rattle at the bottom of the A Pillar on the passengers side, just to the right of the passengers foot well. I had Toyota guys looking for that rattle for an hour or so, three of them crawling inside and under the car, driving it at different speeds.
An older mechanic saw us all staring at the passenger side of the CUV and asked if we had checked the tension nut on the luggage rack on the roof. We are like, "No, you don't understand, the sound is from the foot well." He tightened a loose tension nut on the passenger roof rack and the rattle down in the foot well went away. The sound was moving down the A Pillar to the chassis under the passengers feet. Rattles can be tough to find.
For the tougher rattles, I usually recommend percussive therapy. It only works once in a while, but banging on the car makes me feel a bit better.

Thanks, I'll save the money of the ramps :)

I'm thinking of using a leaf blower, with someone blowing the front at different angles and confirm it is wind speed related.

Yes I checked the air dam, nothing lose there

Best,

Does the noise happen as you hit bumps? Is it a repetitive noise machine the speed of the wheel spin? Or does it make noise as you make sharp turns? Don't rule out a problem with the steering or suspension components or the tires/wheels. We'd need more details to rule these out.
