If you're located within one of the two privately owned Toyota distributorships (GST, SET), you won't have much recourse, they tend to wag the dog (arbitration hearings).
Otherwise, if your car has a clean title, is still under the drivetrain warranty and you have the complete service history including repair orders showing compliance with the recommended scheduled maintenance intervals using OEM parts (Magnuson-Moss won't help), you could demand arbitration. That process is outlined in one of the original manuals and Toyota site. Arbitration rules and outcomes vary by state and Toyota distributorship.
To see if your car is still under warranty and what if any service history was recorded in the Toyota system, join this site and search your VIN.
