Metal Clinking/Thunking when Accelerating/Decelerating Model Y

[royolpunk]

Hi TMC,

I recently picked up my Model Y Performance with a 28xxx VIN at the end of July.

When accelerating hard or braking for turns, there is a weird metal "clunking" at the rear right back of the car. When braking it makes the noise, when accelerating it makes the noise as well - which leads me to believe there is something rolling around in the chassis in the car or loose. I have completely emptied my car and it still makes the noise.

I'm not sure if anyone has had this experience before - does anyone know what it might be, and what a fix could be?

Thank you!

Motor mount? Cant hurt to let them check it out.

Def bring it in and have them check it out. We have a 281XX and no noise. Prob a lose nut or something rolling around.

Yes, experienced same issue with my 46xxx VIN Long Range and have also read others report same. Here's what Tesla Service did:

This work did address it but unfortunately I suspect the sound is returning.

But hope this helps.

Is this a metallic clicking type noise when regen brakes go from regen to last 5moh to stop or like a nut rolling on metal?

The metallic clicking occurs during the weight shift of the chassis when slowing or starting out. Very loud with windows down.

I have similar clunking - first SC said "normal" on my VIN range . They torqued all nuts to spec, clunking still there.

Git worse, more clunking now - have an appt with a second SC for Dec 19th. Techs analyzing audio I sent.

Mine is quick series of metallic clunk (2 to 4), more so on acceleation than deceleration, around 1-15 mph. It is not the "brake or regen" engaging/disengaging.

Mine has done this on 5 separate occasions.

for my edification, is the metal clicking noise normal? I noticed it recently and it’s seems I cannot “unhear” it now if the window is open.

What did the second SC say/do? I‘ve already been through the “oh yeah, they do that sometimes, it’s normal” first SC brush off. They “lubed and tightened” but that made zero different.

Thank you for anything you can report back

Same response from second SC. The tech test drove, torqued all that he can under the hood to spec - reassured that the clunking does not affect safety and efficiency of the car. That it was known to occur on early VIN Model Ys without much needing correction.

That’s so frustrating. I’m sorry.
I’m hoping for good results at my next SC appointment. It happens so often now on mine and frankly it’s kinda embarrassing when I drive people around. If this is “normal” this far into making cars then the Tesla quality noisemakers are are right. *sigh*

I have another appointment tomorrow with a “senior technician”. Last week they replaced two “halfshaft assy, FR”. No difference when they returned it to me.
