Land Rover Discovery Sport battery drain issue due to computer not shutting off after locking doors on Land Rover Discovery Sport

Some Land Rover Discovery Sport owners report experiencing battery drain issues due to the computer system not shutting off after locking the doors, which can lead to warnings like "battery low, please start engine" and other electrical malfunctions. This problem may result from a parasitic drain or a system failure to completely power down, causing the battery to deplete overnight. Additionally, some users have reported that the vehicle unexpectedly shuts off while driving and does not restart for 20 minutes or more, indicating a significant power drain. Even after battery replacement, the drain issue can persist, particularly when the vehicle is parked overnight, sometimes leading to a complete failure to start. Furthermore, the computer system may disable certain functions, such as remote unlock features, to conserve power when it detects a low battery. To address these concerns, it is crucial for owners to diagnose the root cause of the electrical drain, which may involve checking for faulty wiring or malfunctioning components, and seeking assistance from a qualified mechanic or dealership familiar with Land Rover vehicles.
