owner letters. In the event your dealership receives a notice for a vehicle that was sold prior to the Special Service Campaign announcement,
it is the dealership’s responsibility to forward the owner letter to the guest who purchased the vehicle.
Please note that only owners of the covered vehicles will be notified. If you are contacted by an owner who has not yet received a notification,
please verify eligibility by confirming through TIS prior to performing repairs. Dealers should perform the repair as outlined in the Technical
Instructions found on TIS.

Dealer Inventory Procedures
New and Used Vehicles in Dealership Inventory (In-Stock Vehicles)
To ensure guest satisfaction, Lexus requests that dealers complete this Special Service Campaign on any new or used vehicles currently in
dealer inventory that are covered by this Special Service Campaign prior to guest delivery. However, if the campaign cannot be completed
(for example, due to remedy parts availability), delivery of a covered vehicle is acceptable if disclosed to the guest that the vehicle is involved
in a Special Service Campaign.
Lexus expects dealers to visit https://lexus-recall-disclosure.imagespm.info/ and complete a Guest Contact and Vehicle Disclosure Form.
Dealers are expected to provide a copy of the completed form, along with the most current FAQ, to the vehicle buyer.

NOTE: Dealers can identify if any of their new and used inventory has any open campaigns in the Vehicle Inventory Summary

available in Dealer Daily (https://dealerdaily.lexus.com/ ). The Vehicle Inventory Summary may take up to 4 hours to populate
information for newly launched campaigns.
Lexus Certified Used Vehicle (LCUV)
The LCertified policy prohibits the certification of any vehicle with an outstanding Safety Recall, Special Service Campaign, or Limited-Service
Campaign. Thus, no affected units are to be designated, sold, or delivered as a LCertified until all applicable Safety Recalls, Special Service
Campaigns, and Limited-Service Campaigns have been completed on that vehicle.
