Another weird drivetrain noise and getting worse.

[Spikeitaudi]

Well I have another rear drivetrain noise and this is getting really bad. Made the earliest appointment for December 8th, but I really don’t this this is driveable and damaging the car at this point as it is getting louder. Should I just go to the dealer tomorrow and 8am and let them know this needs to be fixed and ask for a loaner? Attached is the video of the noise. It does is off and on but pretty much does it 80% of the time I drive and the knocking is getting louder. The noise is coming from the back center rear drivetrain right below the rear hatch section. Sorry had to save as a zip file as it won't let me upload a MOV extension.

I, 100%, would be at the dealer having this looked at. Sounds terrible...

Did you launch your car often before this? It could be a broken axle, aka half shaft. Do you have any errors or notifications?

Found a pic of the rear end. The half shaft is the shaft perpendicular to the brake disc/red brake caliper. The shaft connects the wheel to the motor. Sometimes the half shafts can break when under heavy launches, repeatedly. If it breaks it is covered under theh warranty so worries there.

No hard launches and it’s been making noise since I got the car in October. No error codes coming up. Just a lot of knocking. It just recently has gotten much worse. I plan on just straight to the dealer tomorrow am. This sounds like a safety issue. Don’t want to make it worse.

Oh geeze since delivery? You should still have your sales advisor's phone number in your contact, so I'd call them up and get them to expedite the issue.

I’m at the Service center right now and they took it straight back. Very curious what the diagnosis is and fix. Am hoping it gets resolved today. Will update this thread when I get an update.

What was the diagnosis and fix. I am having similar sounds

Rear loose lugnut for the rear right wheel.

It certainly can't be half shaft issues. Tesla said they solved that a half decade ago.
