Loss of Brake Power Assist
NHTSA Engineering Analysis EA20001 — closed, opened 2020-08-31 and involving the LAND ROVER RANGE ROVER EVOQUE.
NHTSA investigation EA20001 is a Engineering Analysis opened on 2020-08-31 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 2023-02-27 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
An Engineering Analysis like EA20001 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.
Investigators summarized the matter as follows: "On August 31, 2020, ODI upgraded PE18-014 to Engineering Analysis (EA)20-001 to continue its investigation of brake vacuum pump failures in model year (MY) 2012-2013 Range Rover Evoque vehicles and peer Jaguar Land Rover..." 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 August 31, 2020, ODI upgraded PE18-014 to Engineering Analysis (EA)20-001 to continue its investigation of brake vacuum pump failures in model year (MY) 2012-2013 Range Rover Evoque vehicles and peer Jaguar Land Rover (JLR) products equipped with 2.0L GTDI engines fitted with Magna vacuum pumps. This investigative activity has focused on the cause, scope, and effect of inadequate vacuum supply at the vehicles brake booster with its attendant increases of brake pedal effort and diminished braking performance. Following a detailed analysis of data collected, the alleged defect is progressive and reasonably detectable with adequate power braking assist available prior to complete pump failure; occurs at marginal failure rates, particularly where the vehicle age is considered; and the complaint trend dissipated to one occurrence per year over the last three calendar years. Based on the analysis conducted, this investigation has been closed. The closing of this investigation does not foreclose the Agency from taking further action, if warranted, or the potential for a future finding that a safety-related defect exists, based upon additional information the Agency may receive. For a detailed summary of the investigation see attached closing resume document.

About This Investigation Type
An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
