model.
The following information is provided to inform you and your staff of the program notification schedule and your degree of involvement.

– 2015 Model Year GS450h, and certain 2016 -2019 Model Year RX450h Vehicles. The specific condition covered by this program
is related to certain internal malfunctions of the Brake Booster Assembly. One or more of the following specific Diagnostic Trouble Codes
(DTCs) C1391, C1252, C1253 or C1256 will be stored in the vehicles memory to be used as verification. If the condition is verified, the

Customer Handling, Parts Ordering, and Remedy Procedures
Customer Contacts
Customers who receive the owner letter may contact your dealership with questions regarding the letter and/or the Customer Support
Program. Please welcome them to your dealership and answer any questions that they may have. A Q&A is provided to assure a consistent
message is communicated.

Salvage Title Vehicles
There is no New Vehicle Limited Warranty coverage or non-emission CSP coverage for vehicles that have been branded as salvage, total
loss, true mileage unknown, or similar title under any state’s law. Nonetheless, every attempt should be made to complete an open emission
related CSP when circumstances permit, unless noted otherwise in the CSP dealer letter.
•

This CSP IS NOT emission related; therefore, vehicles branded as salvage, total loss, true mileage unknown, or similar title are NOT
ELIGIBLE for coverage under this CSP.

For complete details on this policy, refer to Lexus Warranty Policy 4.17, “What Is Not Covered by The Lexus New Vehicle Limited Warranty”.
Customer Marketing
Direct marketing of this Customer Support Program is strictly prohibited pursuant to the Lexus Warranty Policy 5.22, “Warranty
Solicitation.” Non-compliance of this policy may result in a claim debit.
Media Contacts
It is imperative that all media contacts (local and national) receive a consistent message. In this regard, all media contacts must be directed to
Tyler Litchenberger (469) 292-2671 in Lexus Corporate Communications. Please do not provide this number to customers. Please provide
this contact only to media.
Parts Ordering Process
It is possible that parts for this campaign are either required to be ordered in Campaign Part Order Request (CPOR) on Service Lane, or
have been placed on Manual Allocation Control (MAC) due to potential limited part availability. Please check the CPOR/MAC report on
Dealer Daily for the most up-to-date parts ordering information. Dealers can identify which parts ordering method to use by reviewing the
parts information section of Dealer Daily and checking for a MAC code on the part numbers below. For MAC code C, order through CPOR.
For MAC code D, refer to the MAC report for further instructions.
As this is a Customer Support Program, the condition MUST be verified by inspecting the vehicle. Therefore, dealers SHOULD NOT
increase their stock of related repair parts. Dealers are requested to only order parts for vehicles experiencing this condition only. DO NOT
ORDER FOR STOCK. As always, if a customer experiences the condition described, dealers should conduct appropriate diagnosis and
order the applicable parts.

vehicles have the repair performed correctly; technicians performing this recall repair are required to currently have completed all of the
following courses:
• LIC209A – Electrified Vehicle Powertrain Repair
It is the dealership’s responsibility to select technicians that have completed the above courses to perform this recall repair. Carefully review
your resources, the technician skill level, and ability before assigning technicians to this repair. It is important to consider technician days off
