Toyota recalled RAV4 PHEV vehicles built between 14 July 2020 and 26 May 2022.

The dealer will replace the DC-DC converter. You won't usually pay for it.1
What’s Wrong
The plug-in hybrid system of the subject vehicles includes a DC-DC converter that reduces the voltage of the electricity from the Hybrid Vehicle (HV) battery in order to charge the vehicle,s 12V battery. Contained within the DC-DC converter is a current rectifying module that is installed on the circuit board. Some of these modules may have been damaged during production by the supplier and could fail so creating a short circuit. This allows current from the 12V battery to continue to flow through the module and the module will generate heat. Under certain conditions if excessive heat is generated components within and outside the DC-DC converter could sustain thermal damage increasing the risk of a vehicle fire.
