Toyota Warranty extension 22TE09

NHTSA summary, verbatim

Although the HV Floor Under Wire Harness and Rear Traction Motor Cable is covered by Toyota’s New Vehicle Limited Warranty for 3 years or 36,000 miles (whichever comes first), we at Toyota care about the customers’ ownership experience. Toyota is providing extended coverage under this Customer Support Program for repairs related to excessive corrosion to the wire harness connections at the Rear Motor Generator. Excessive corrosion can cause AM Radio Static during certain drive cycles, or the vehicle may not start.

Covers

Coverage window

This coverage has been expanded from 8 years from date of first use or 100,00 miles (whichever comes first) to 10 years/unlimited miles. To maintain the expanded 10 years/unlimited mile coverage the vehicle must have LSC 25TD01 completed by September 30, 2028.

Where this shows up in our reports
