Tap a recall to see the problem, the risk and the fix.

Hybrid propulsion systemOct 4, 2018 · NHTSA campaign 18V684000 · 807,329 vehicles

Problem: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles.

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

Fix: 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.

Hybrid propulsion system: inverter; electrical system:softwareFeb 12, 2014 · NHTSA campaign 14V053000 · 698,457 vehicles

Problem: 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.

Risk: 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.

Fix: 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.

Seats; air bags:frontal:sensor/control module-inactiveJan 16, 2013 · NHTSA campaign 13V014000 · 3,235 vehicles

Problem: Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.

Risk: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

Fix: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.
