## NHTSA's summary

This Preliminary information communicates to the dealers on the process to be able to order a replacement High Voltage battery pack for a vehicle that has a High Voltage battery battery concern and is not on the current open recall list. This document will add in advising the dealers to contact TAC with needed information so TAC can review the data to verify that the vehicle need a High Voltage battery and then TAC will release the High voltage battery so the dealer can repair the vehicle for the customer.
