Junction Box Repair

Refer to the warranty section of this campaign for details of the 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.
CUSTOMER COMMUNICATION
Should this campaign mean that you are unable to deliver an affected vehicle to a customer at an agreed handover date, advise the
customer of the following:
'JLR are committed to delivering vehicles to our customers of the highest quality, complete with the very latest hardware and
software. Our vehicles are continually evolving with our Engineering and Design teams constantly looking for new and innovative
ways to further enhance and develop our vehicles. JLR have advised us that there is an update to be completed on your vehicle
and have instructed us to complete this action prior to handing the vehicle over to you. JLR apologize that this update may delay the
delivery of your new vehicle but are committed to make sure customers benefit from the very latest technology to make sure your
ownership experience is the best possible.'
If necessary, you may communicate technical details of the repair or update that is required on the vehicle, this is at your discretion.
RETAILER EMPOWERMENT
We appreciate the frustration experienced by both our customers and JLR retailers / authorized repairers with regards to the launch
of any Update Prior to Sale (UPS) notice.
Following the launch of Retailer Empowerment (and where you feel it appropriate), you now have the ability to offer goodwill to
customers who have suffered delays in the delivery of their vehicle. Any goodwill offer should be specifically for a customer whose
vehicle delivery has been delayed due to UPS activity to acknowledge the poor experience.
Should you have any questions, contact the Customer Relationship Center (CRC) in the first instance for help and support.
