Owner Letter Mailing Date
Toyota will begin to notify owners in late March 2019 by in-vehicle head unit notification and first class letters.
Toyota makes significant effort to obtain current customer name and address information from each state
through industry resources when mailing 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 customer 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 customer satisfaction, Toyota 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
customer 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 customer that the vehicle is involved
in a Special Service Campaign.
Toyota expects dealers to use the attached Customer Contact and Vehicle Disclosure Form to obtain vehicle
buyer information. Dealers are expected to provide a copy of the completed form, along with the most current
FAQ, to the vehicle buyer. Toyota and the dealer may use this information to contact the customer when the
remedy becomes available.
Keep the completed form on file at the dealership and send a copy to quality_compliance@toyota.com. In the
subject line of the email state “Disclosure Form K0A” and include the VIN.
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.toyota.com/). The Vehicle Inventory Summary
may take up to 4 hours to populate information for newly launched campaigns.
Toyota Certified Used Vehicle (TCUV)
The TCUV 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 TCUV until all applicable Safety Recalls, Special Service Campaigns, and Limited Service Campaigns have
been completed on that vehicle.

Customer Handling, Parts Ordering, and Remedy Procedures
