The issue is that the TPMS might not be able to locate the sensors while the vehicle is underway. As a result, the low tire pressure warning light could illuminate even if the tire pressures are accurate. If this happens and one of the tires then loses air pressure, the driver wouldn't know about it.
The fix is simply an update of the Body Control Module software for most models. However, it's not compatible with the 2013 LR4, and these vehicles are getting new sensors. Obviously, this is being done at no charge to owners by Land Rover, and the recall is expected to start on December 1.

Jaguar Land Rover North America, LLC (Land Rover) is recalling certain model year 2014 Range Rover and Range Rover Sport and 2013-2014 LR4 vehicles manufactured September 16, 2013, to June 30, 2014. In the affected vehicles, the Tire Pressure Monitoring System (TPMS) may fail to learn the locations of the individual sensors while the vehicle is being driven. As a result, the low tire pressure warning light will illuminate, despite the the tire pressures being within specification. Should one of the tires subsequently lose air pressure, the driver would not be notified of the change in air pressure.
If the TPMS light illuminates because the sensors cannot be located, it could mask an actual low tire pressure condition, possibly resulting in tire failure, increasing the risk of a crash.
Land Rover will notify owners, and dealers will update the Body Control Module (BCM) software, free of charge. The recall is expected to begin on December 1, 2014. Owners may contact Land Rover customer service at 1-800-637-6837, Option 9. Land Rover's number for this recall is P050.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
