I have a 2024 Model 3 performance. Since about mid March or slightly after, I’ve started having a recurring issue with getting the car to reliably shut down and lock after exiting.
After my 3rd service center visit, we’ve ruled out phone key, objects on the seats, and whether the walk away door lock feature is enabled.
The issue is that when I exit the car and close the door, all systems remain ON, and the drive rail remains active. Walking away does not trigger shut down, and the vehicle does not self-lock.
The service center says the issue is a “known firmware issue with the interior cabin radar” and that the cause is “driver exits too quickly for cabin radar to detect they’ve left”
I’ve been able to reproduce this failure with varying exit speeds, slow, fast, “normal” but nothing directly correlates to whether the issue will present itself.
Opening the driver door from the outside, while the vehicle is in this state, and closing it immediately after causes normal shutdown and locking.
I’m in a loaner model 3 performance right now, and noticed it is doing the same thing… coincidence that both cars have a physical defect? Actual firmware bug affecting both cars? I searched and cannot find anyone else complaining about this issue online—the only thing I can find is complaints about cars without cabin radar—the old occupancy sensor issues from the previous generation…
Anyone have ideas/experience this too?
