Abstract
A vehicle memory sub-system can be switched from a normal mode to a pre-shutdown mode and initiate a media management operation before shutting down. The mode switch and/or media management operation can be performed in response to receiving a shutdown or pre-shutdown command for the vehicle. After completion of the memory management operation the vehicle and/or memory sub-system can be shutdown.
