What's wrong

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.

Consequence

If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.

Remedy

Toyota will notify owners, and dealers will update the software for the motor/generator control electronic control unit (ECU) and the hybrid control ECU as necessary, free of charge. The recall began January 22, 2019. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is J0V.
