Owner Notification Date
Toyota will begin to notify owners in late September 2024. A sample of the owner notification has been
included for your reference.
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 24TC05” 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.

registration renewal. It is important to note that the forms are an official

April 2025. If the vehicle owner’s warranty claim will not be processed
and paid prior to this date, please be sure to complete a form and
provide it to a California owner.

Install the Authorized Modifications Label after the repairs have
been completed. Using a permanent marker, fill out the label and
affix it to the location under the hood as indicated.

Form booklets and Authorization Labels can be ordered from the
MDC (Booklet material number 00410-92007, Label material
