NHTSA Preliminary Evaluation PE18014 — closed, opened 2018-12-01 and involving the LAND ROVER RANGE ROVER EVOQUE.
NHTSA investigation PE18014 is a Preliminary Evaluation opened on 2018-12-01 and currently closed. The subject of record is LAND ROVER RANGE ROVER EVOQUE, which places this file inside the Office of Defects Investigation queue for LAND ROVER. Latest activity on this investigation was logged on 2020-09-10 — 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 Preliminary Evaluation like PE18014 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "On December 1, 2018, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE18-014 to investigate allegations of brake vacuum pump failure in model year (MY) 2012 through 2014 Range Rover Evoque vehicl..." 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
On December 1, 2018, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE18-014 to investigate allegations of brake vacuum pump failure in model year (MY) 2012 through 2014 Range Rover Evoque vehicles. During PE18-014, ODI identified 33 complaints and field reports related to the alleged defect in the subject vehicles. Seven of the complaints were received by ODI and 26 were reported as consumer complaints or field reports in the Jaguar Land Rover (JLR) response to ODI's Information Request letter for PE18-014. All the complaints and field reports identified by ODI involved MY 2012-2013 Range Rover Evoque vehicles. ODI's analysis of warranty data supplied by JLR identified 198 claims related to the alleged defect in MY 2012-2013 vehicles, resulting in a claim rate of 0.84 percent. ODI identified just 6 claims in the MY 2014 Range Rover Evoque vehicles, resulting in a claim rate of0.09 percent. The subject vehicles are equipped with 2.0 liter Gasoline Turbocharged Direct Injection (GTDI) engines that utilize a mechanically driven single vane rotary vacuum pump supplied by Magna International (Magna). The 2.0L GTDI engines and subject Magna vacuum pumps were used by JLR in the following applications: MY 2012-2017 Land Rover Range Rover Evoque (L538), MY 2013-2015 Land Rover LR2 (L359), MY 2015-2017 Land Rover Discovery Sport (L550), MY 2013-2015 Jaguar XF (X250), and MY 2017 Jaguar XE (X760). Field return analyses of failed vacuum pumps from these products has determined that the failures were caused by blockage of the orifice supplying lubricating oil to the pump. Magna and JLR have attributed the blockage to oil "sludge" resulting from failure to perform oil changes at the specified maintenance intervals. This Preliminary Evaluation has been upgraded to an Engineering Analysis (EA20-001) covering MY 2012-2013 Range Rover Evoque vehicles (subject vehicles). Other JLR products equipped with 2.0L GTDI engines and subject Magna vacuum pumps will be
About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
