Land Rover LR2 tailgate door opens after starting vehicle, possible electronic or lock mechanism issue on Land Rover LR2

Some Land Rover LR2 owners report experiencing issues with their tailgate doors opening unexpectedly after starting the vehicle. These problems may stem from a faulty body computer that misinterprets the tailgate status, leading to incorrect operation. Additionally, a malfunctioning electric lock mechanism can cause the latch to continuously lock and unlock the tailgate unexpectedly. Some owners find that a sticky or faulty door ajar switch in the upper window latch mechanism can prevent proper operation of the lower tailgate. Troubleshooting may involve checking for a failed switch in the tailgate itself, as well as experimenting with the electronic tailgate unlock feature on the dashboard. In certain cases, the electronic locking mechanism may be defective, necessitating access to replace the lock. Lastly, mechanical issues related to the latches may arise, as these typically require multiple ratchets to latch properly, and a constant voltage supply can inadvertently energize the latch. Addressing these various factors may help resolve the unexpected tailgate operation.
