Creaking/Knocking Sound from Rear Right Side – Any Ideas?

[a310pilot]

Whenever I accelerate or decelerate in my Cybertruck, I hear a creaking or knocking sound coming from the rear right passenger side. It also happens occasionally when turning or driving over speed bumps or potholes.


I’ve already checked the door latch—it’s not loose. I’ve also experimented with disabling the child lock and window lock, and tried adjusting the window (fully down, halfway, and even a quarter down), but the sound persists.

Any idea what this could be?

I’ve posted a video with this, hope the audio is clean.

I had a weird sound like this too, turned out to be the door presenter rattling around I guess.

I had the same issue. I took it in and it was some loose trim inside the vehicle. Easy fix for the service center.

Oh thank god OP I thought I was going crazy. Have the same exact issue but on a lower magnitude. I was waiting for it the get more frequent and louder.

My wife opted for this solution once in her daily driver, at least until the pistons seized.
Thankfully our Teslas have way less mechanical issues to deal with.
Only add washer fluid.

If you can hear it outside the vehicle it's probably loose bolts in the underbody sheilding. I had the same issue and found multiple loose bolts. Believe there is a service doc related to this as well.
