NHTSA Recall Query RQ19004 — closed, opened 2019-06-28 and involving the LAND ROVER ROVER.
NHTSA investigation RQ19004 is a Recall Query opened on 2019-06-28 and currently closed. The subject of record is LAND ROVER ROVER, which places this file inside the Office of Defects Investigation queue for LAND ROVER. Latest activity on this investigation was logged on 2020-11-05 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Recall Query like RQ19004 evaluates whether a previously issued recall is actually fixing the problem. NHTSA opens an RQ when owners continue to report the original defect after the recall remedy is installed, or when completion rates fall short of the agency's expectations for that risk tier.
Investigators summarized the matter as follows: "In October 2012, Jaguar Land Rover LLC (JLR) submitted a Defect Information Report (DIR) to NHTSA describing a defect condition that could result in pressurized fuel leaks around the fuel supply line connection on the up..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related LAND ROVER files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
In October 2012, Jaguar Land Rover LLC (JLR) submitted a Defect Information Report (DIR) to NHTSA describing a defect condition that could result in pressurized fuel leaks around the fuel supply line connection on the upper surface of the fuel tank assemblies of approximately 4,152 model year (MY) 2010 Jaguar XF vehicles equipped with 5.0L engines and manufactured between April 2009 and January 2010 (Recall 12V-521). The DIR indicated that the fuel system operating pressures of 5.0L gasoline engine XF vehicles may exceed the design specification under certain conditions, which may result in cracks in the fuel tank outlet flange. In January 2010, JLR changed the design of the tank outlet flange from the original version with no internal ribs, part number 9X23-9A309-AC (“AC flange”), to a revised part with internal ribbing reinforcing the area of the flange at the base of the fuel supply port where the cracks were occurring (“AD flange”). The scope of 12V-521 included 43 MY 2011-2012 XF vehicles with 5.0L engines that were equipped with the AC flanges as service replacement parts. In addition, in March 2016, JLR recalled 28 additional MY 2010 XF vehicles built with 5.0L engines and AC flanges that were inadvertently excluded from 12V-521 (Recall 16V-187). The AD flange was later replaced in production by the AE flange, which had internal ribbing like the AD flange and was used by JLR as the remedy part for 12V-521 and 16V-187. All the subject fuel tank flanges (AC, AD & AE) were supplied to JLR by Continental AG (now Vitesco Technologies). By October 2019, JLR had completed the recall remedies for 12V-521 and 16V-187 in 4,080 vehicles, resulting in an overall completion rate of 97 percent. On June 28, 2019, ODI opened RQ19-004 to investigate the scope and remedy for recalls 12V-521 and 16V-187, based on 30 complaints alleging fuel odor or leakage from the tank flange, including 19 in MY 2010 XF 4.2L vehicles equipped with the AC flange and 11 in MY 2010 through 2012 X
About This Investigation Type
A Recall Query (RQ) evaluates the effectiveness of a previously issued recall. NHTSA opens an RQ when consumer complaints suggest that a recall remedy may not be adequately addressing the safety issue, or when the recall completion rate appears insufficient.
