NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA18-004.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
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.
Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Engineering Analysis EA18-004. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.
What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
