Land Rover Engineering Analysis EA18004: Door latch failure
2016 Land Rover Range Rover Sport
Door latch failure
- On May 24, 2019, Jaguar Land Rover North America, LLC (JLR) submitted two Part 573 letters to NHTSA describing door latch defects that could result in doors opening while driving in certain model year (MY) 2013-2016 Range Rover and Range Rover Sport vehicles equipped with JLR-€™s Unilatch Keyless Vehicle (KV) entry system.Recall 19V-392 (JLR Recall N335) describes a KV lever binding defect in approximately 65,385 MY 2013-2016 Range Rover and MY 2014-2016 Range Rover Sport vehicles built between May 9, 2012 and March 5, 2015. Moisture intrusion may result in KV motor bearing corrosion, which may prevent the KV lever from returning to the home position and prevent the latch pawl from properly engaging the latch claw. Vehicles recalled under 19V-392 will be checked for a pre-existing error state and mechanically disabled if an error is detected. If no error is detected, the vehicles will receive a software update that will disable the KV entry function on the vehicle.Recall 19V-390 (JLR Recall N336) describes a defect in the KV latching system of left-side doors in approximately 28,671 MY 2016 Range Rover and Range Rover Sport vehicles built between October 1, 2015 and May 27, 2016. A spring in the KV latching system may jam between the outside transmission lever and chamfer bush, preventing the latch assembly from returning to its correct position and fully latching the door. Vehicles recalled under 19V-390 will have the left-side latch assemblies replaced with assemblies that meet the engineering specification.ODI-€™s analysis of consumer complaints and field reports identified a total of 161 latch failures in the subject vehicles, including 57 involving doors opening with the vehicle in motion. The analysis found that 157 of the latch complaints and 56 of the door opening in motion incidents involve vehicles and latch assemblies covered under Recalls 19V-390 and 19V-392. Engineering Analysis EA18-004 is closed based upon JLR-€™s recall actions. For more information about the recall defect conditions and related field data, see the attached report.
