If you haven't done so already, check your warranty booklet for this from the 2020 warranty & maintenance guide downloaded from Toyota's website:
If your concern has still not been resolved
to your satisfaction, Toyota offers
additional assistance through the Dispute
Settlement Program, a dispute resolution
program administered by the National
Center for Dispute Settlement. The
purpose of the Dispute Settlement
Program is to resolve disputes through
arbitration — a process by which two
parties authorize an independent third
party to hear and resolve a dispute. The
program is informal and free of charge.
To request that your case be reviewed
through the program, complete the
customer claim form in the Owner’s
Warranty Rights Notification booklet
(found in your glove box) and mail it to:
National Center for Dispute Settlement
P.O. Box 688
Mt. Clemens, MI 48046
To initiate arbitration, you must complete
an NCDS customer claim form and mail it
to NCDS. To request a form, call NCDS
at (800) 777-8119 or obtain a copy at
www.ncdsusa.org. When you call,
please have your vehicle identification
number, the current mileage on your
Toyota and the names of your selling and
servicing dealerships.
