Why would your preset seat move all the way forward when you turn ignition off?

When you turn off the ignition, the preset seat position may move forward to allow easier access to the rear seats or to make it simpler for the driver to exit the vehicle. Some vehicles have a feature that automatically adjusts the seat to a designated position for convenience. Additionally, it could be a safety feature designed to ensure that all passengers can exit the vehicle comfortably. If this behavior is not intended, it may indicate a malfunction in the seat adjustment system.
