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.
