An unexpected hybrid power system shut down may increase the risk of a crash.

Remedy

Toyota will notify owners, and dealers will perform a software update for the hybrid system. If the vehicle has experienced an inverter failure with certain hybrid system faults related to this condition, the inverter assembly will be repaired or replaced, prior to software update. All repairs will be performed free of charge. This recall began July 24, 2020. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is 20TB10 / 20TA10.

Defect

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.

14V053000Fuel SystemFebruary 12, 2014 · 698,457 units

Defect

Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.

Consequence

The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.

Remedy

Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge. The recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.

Open NHTSA investigations

DP23005

Brake Actuator Valve Wear

The Office of Defects Investigation (ODI) has received a petition dated September 19, 2023 from the owner of a 2012 Toyota Prius V requesting that ODI reevaluate its decision to deny DP19-004. In the letter, the petitioner reported experiencing an unexpected and complete loss of brake power while driving, accompanied by multiple dashboard warning lights. This petition is based on the petitioner's direct experience and assessment that ODI closed DP19-004 because its prompting petition was withdrawn by that petitioner. ODI will review the work conducted during DP19-004 and a review of any additional related complaints and crashes via a new defect petition The petition and related materials can be reviewed at NHTSA.gov under the following ODI number:11553736.
