Rattling Undercarriage

[MauiDan]

The undercarriage of my new AWD Cybertruck with Cyberwheels rattles badly on bumpy roads and especially on the unpaved road leading into my property. Something definitely seems to be wrong.
I recently drove a GMC truck and a Jeep on the same road and neither does this.
I would appreciate any suggestion of what may be the problem.
I live a very long way from a service center.
Thanks

I've heard of bolts that were not screwed on completely, I'd suggest checking that first.

What do you mean undercarriage? There is a battery, and a front and rear subframe, each holding a motor and suspension. Where are you hearing the rattling from?

 

[MauiDan]

The rattling seems mostly from the wheel areas,, but hard to tell. I would think it involves the suspension.

All 4 areas? Under what condition does it occur? Can you post a video or sound recording of it?

I have a FS Beast delivered 06/2024 and mine has started doing that recently too... It's not that loud with the windows up, but as soon as I put the windows down I can hear just how loud it REALLY is... And it's so loud it's embarrassing.... Sway bar and links seem fine from what I can see, so I'm at a loss for what it could be.... Any ideas?

Are you able to hear it from the outside when its driving to confirm?

If you are not entirely sure where its coming from, when your going over the bumps that cause it to rattle, gently rest your foot under the brake pedal and see if the rattle goes away.

No, it's definitely coming from outside, and from the rear. I'll see if I can get a video tomorrow and upload it.

A lot of good mechanics and suspension specialists have specialized microphone set ups that can hear and isolate suspension noises while driving. I dont think tesla service does this, but its worth looking into

I kinda have a rattle but it has to be dead quiet in the cab to hear it.

You can have a Tesla service tech hop in for a ride and show them the noise. Before doing that drive around where the service center is located and find a spot in the road that makes the noise so you can easily replicate it for the tech. Sadly I failed to replicate the noise with the tech in the car but it is noted on my profile.
