What NHTSA investigated
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.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.
