Land Rover engineering analysis EA18004
Door latch failure. NHTSA’s Office of Defects Investigation opened this engineering analysis about the latch on 7 model years (2013–2016). Opened Jul 2, 2018, closed Oct 17, 2019 after 16 months. It led to safety recall 19V390000, 19V392000. became a recall
What NHTSA says
Source: Office of Defects Investigation, as filedOn 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.
A Engineering Analysis is the deeper stage, usually upgraded from a Preliminary Evaluation: NHTSA tests, requests engineering documents and decides whether a safety defect exists. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one became a recall. The campaign page carries the manufacturer’s filed defect, risk and remedy, the build window and every model year covered; whether one specific vehicle is included is settled by VIN at nhtsa.gov/recalls.

Common questions
Source: NHTSA Office of Defects InvestigationIs EA18004 a recall?
No — it is the investigation that led to one. Recall 19V390000, 19V392000 is the campaign; its page carries the remedy.
Is EA18004 still open?
No. It closed on Oct 17, 2019 and led to recall 19V390000, 19V392000.
Which vehicles does EA18004 cover?
NHTSA opened it on 7 model years: 2016 Land Rover Range Rover, 2013 Land Rover Range Rover, 2014 Land Rover Range Rover, 2015 Land Rover Range Rover, 2013 Land Rover Range Rover Sport, 2014 Land Rover Range Rover Sport and more. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
