Knock noise at startup

[Alxstang]

Hello everyone,

first time posting here. I was wondering if any other s650 owner has this problem. Almost everytime i start the engine, immediately after, a KNOCK noise comes from underneath the car. Not sure what is it and im kinda worried. Hope you can help.
2024 GT, 10spd

I have the exact same problem. And some times even more noise and the car moves back anf forth.

Mine does jerk at startup in Park, in Neutral with No bakes applied, it will jerk 5 seconds later.

I only get a clink/knock underneath the rear passenger side once I put in drive?

Hello,
Is there any updates on the topic? Mine does it only if I re-start the car within a few minutes after shuting off the engine. But if the car was off for few hours it starts normal without any issues.

Hi. looks like i’ve got same problem as you have. After start up, these noise and shock comes immediately from underneath the car. Wonder where it’s comming from and why these issues are happening. Just guessing it’s from the transmission and feels like it isn’t normal.

mine does same man
