SERVICE CAMPAIGN BULLETIN

DESCRIPTION OF ISSUE AND THE EFFECT ON VEHICLE OPERATION

A potential concern has been identified on specific vehicles within the above vehicle range.

A concern has been identified with certain 2019 and 2020 model year Range Rover Evoque and Land Rover Discovery Sport Mild Hybrid Electric Vehicle (MHEV) vehicles. An electrical overload event in the 48V electrical system may cause a failure of the Metal Oxide Semiconductor Field Effect Transistor (MOSFET). Failure of the MOSFET may cause an electrical cascade failure, causing the Direct Current to Direct Current (DC/DC) converter to experience an electrical short where the 12V circuit shorts to ground.

When the DC/DC converter experiences an electrical short to ground, the 12V electrical system will discharge, this will be indicated by the battery warning lamp on the Instrument Panel Cluster.

In extreme cases, the vehicle occupants may notice a burning smell and/or smoke from the DC/DC converter vent into the passenger compartment. Where sufficient oxygen exists, a sustained vehicle fire may occur.

ACTION TO BE TAKEN

JLR has taken the decision to recall affected vehicles to repair the vehicle.

Following procedures appropriate to your market and as required by local legislation, owners of affected vehicles should be contacted requesting that the owner contact their nearest retailer/authorized repairer as soon as possible to arrange for the repair to be completed. The National Sales Companies (NSCs), Importer, Regional Office or Government agency will contact the customers. If you have any questions about this process, please contact your NSC/Importer or Regional Office for more information. 

Check the JLR Warranty Portal to make sure affected vehicles are correctly identified prior to starting this campaign. The Warranty Portal will be updated to reflect only those vehicles affected.

Retailers/authorized repairers are reminded that they must not sell vehicles identified as affected by this campaign until such time as the repair has been successfully completed. 

An owner may indicate that a repair has already been completed for this concern, in which case the full cost of the repair should be reimbursed. Refer to the warranty section of this campaign for details of the Customer Reimbursement and Related Damage Process. At the time of confirming a booking for a vehicle repair, make sure you check the Warranty Portal to confirm if there are any other outstanding campaigns, to make sure the correct parts are available and adequate workshop time is allocated for repairs to be completed in one visit.
