Land Rover started equipping some of its vehicles with a Unilatch Keyless Vehicle entry system in 2015. The system either has control logic or short circuiting issues when controlling the release levers, never allowing the doors to latch even though they appear to be properly closed.
Through an internal investigation, Land Rover found problems in the electrical function of the keyless entry system. Short-circuits were turning the keyless entry motor into a brake, stopping (or slowing down) the keyless lever from returning to its "home" position. When this happens, the door may appear to be closed but it's not properly latched shut.
In July of 2015, Land Rover recalled 65,000 SUVs because the doors were failing to latch in the primary or secondary closed positions.
To repair the problem, Land Rover dealers updated the keyless system software in certain vehicles manufactured up until March 9, 2015. This included the 2013-2016 Range Rover and 2014-2016 Range Rover Sport.
NHTSA received complaints from both owners with the upgraded software and owners left out of the orignal recall. Meanwhile, Land Rover discovered at least 43 additional complaints related to the door latches with 14 of those saying the doors opening while the car was in motion.
This problem has popped up in the following Land Rover generations.
Most years within a generation share the same parts and manufacturing process. You can also expect them to share the same problems. So while it may not be a problem in every year yet, it's worth looking out for.
