The Hazard

 

Hybrid DC-DC Converter: The subject vehicles have a DC-DC Converter to reduce voltage from the HV Battery in order to charge the auxiliary battery. Due to improper soldering of the circuit board during manufacture the auxiliary battery may no longer receive power from the DC-DC Converter. This could result in a total shut down of the hybrid system. Warning lights, audible chimes and warning messages will display prior to a total shut down. NOT ALL VEHICLES IN THE MODEL YEARS ARE INVOLVED.

 

What to do

 

As an owner of an involved vehicle, you will be contacted by registered letter requesting you to contact your nearest authorised Toyota Dealer to arrange a convenient time to have the repairs completed at no cost. Alternatively, contact Toyota's Customer Dialogue Centre to discuss.
