Wind, Bearing, or Coolant Noise?

[bradsass1]

Same issue here. Took it in for service and they had me drive another Cybertruck on the lot. It had the same sound.

I love how you purchase an 90K truck and then are told it's okay, they all have a whistle/rustling noise from a hole somewhere that we can't find.

Chiming in that I also have the noise often, and it goes away every time when turning left. The noise doesn’t happen every single drive. Sometimes I’ll be going a constant straight speed and it’s gone, then comes back.

Did anybody figure this out? It’s definitely not wind related. You can be going at a constant speed and no sound, then the sound randomly appears. Why would it go away when turning left?

Sold mine for a foundation with free supercharging and this one has no noise.

My foundation series with free supercharging has had the whistling morse code sound since day one (Vin# 37k). The beast loaner I had for a couple weeks that was slightly newer than my foundation also had it I believe.

Edit: Just realized the whistling sound isn't the sound people are discussing here.

Aliens.

It only happens in mine when it’s below 45 degrees outside. I heard it all of last winter, it stopped in May, and just started again last week.

Folks, I think I found the fix!!! This has been bugging me for more than a year. After I realized it wasn't bearings or coolant or pumps....it had to be air flow. The key was you would hear it going straight, or a right curve, but not on a left curve. So, what I did today was to add a rubber sealing strip at the vertical gap between the driver's side frunk and the left front quarter panel. Voila! The noise is gone. Next I will do it to the right front gap as well, and maybe even along the top edge of the frunk. Bottom line....that high speed air (40-80 mph) was getting inbetween metal surfaces along that substantial gap, and causing rustling or vibration noises!

Can you take a pic and mark it up just so my imagination can not over engineer as usual please

Did you put anything in the gap between the light bar and the panel? Mine is more significant on that side compared to the the passenger side.

 

[QuantumGlen]

I dont have a light bar.

I dont have a light bar.

The DRL, not a light bar on top

So no, I did not try reducing the daylight running light bar gap.
