Land Rover engineering analysis EA20001
Loss of Brake Power Assist. NHTSA’s Office of Defects Investigation opened this engineering analysis about the vacuum on 2 model years (2012–2013). Opened Aug 31, 2020, closed Feb 27, 2023 after 2.5 years without a recall. closed
What NHTSA says
Source: Office of Defects Investigation, as filedOn 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. The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 10986358, 11025409, 11083348, 11131896, 11149724, 11231234, 11343256, 11425440, 11485127.
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 closed without a recall. That means NHTSA found no defect trend it chose to act on at the time, or the manufacturer addressed the condition another way (a service campaign or a bulletin, which have their own pages). A closed file can be reopened if new reports arrive.

Common questions
Source: NHTSA Office of Defects InvestigationIs EA20001 a recall?
No. A engineering analysis is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one closed without one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.
Is EA20001 still open?
No. It closed on Feb 27, 2023 without a recall.
Which vehicles does EA20001 cover?
NHTSA opened it on 2 model years: 2012 Land Rover Range Rover Evoque, 2013 Land Rover Range Rover Evoque. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
