Dealer Inventory Procedures

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 23TC02” 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 (Non SET and GST dealers: 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.
