Potential uncomplete lock of rear Trunk? (Model 3)

Hello I m.the happy owner of a Tesla Model 3 LR (2021). I've just realised that when i closed my rear trunk (automatically or manually) , i do not have anymore the sound of the electric lock at the end of the closure. However the trunk is properly detected closed by the car. Is it a common issue? Any solution to proposed before opening a ticket to Tesla? I ve already reboot the car. Thanks
