NHTSA's VIN data lists no trims for the 2012 Prius, so these are the versions EPA tested, by its names. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 449 complaints with NHTSA about the 2012 Prius. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 7 recall campaigns for the 2012 Prius over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
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.
Risk: 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. Note: The software updates in this recall are needed even if the vehicle had the software previously updated under recalls 14V-053 or 15V-449.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2012-2015 Prius Plug-in Hybrid vehicles. The hybrid battery contains an Electric Vehicle (EV) fuse that may fracture after repeated high-load driving conditions such as climbing long hills.
Risk: The failed fuse may cause the hybrid system to shut down resulting in the loss of power. Loss of power while driving at higher speeds can increase the risk of a crash.
Remedy: Toyota will notify owners, and dealers will replace the EV fuse, free of charge. The recall is expected to begin January 8, 2018. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is H0R.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2010-2012 Toyota Prius, 2010 and 2012 Toyota Prius Plug-in Hybrid, and 2011-2012 Lexus CT200h vehicles. A weld in the curtain shield air bag inflator may crack causing one or both portions of the inflator to eject into the passenger cabin.
Risk: If either portion of the curtain shield air bag inflator ejects into the passenger cabin, there is an increased risk of injury to vehicle occupants.
Remedy: Toyota will notify owners, and dealers will install retention brackets to the curtain shield air bags, free of charge. The recall began on October 17, 2016. Owners may contact Toyota Customer Service Department at 1-800-331-4331. Toyota's number for this recall is Toyota G0U, and Lexus GLJ.
Southeast Toyota Distributors, LLC (SET) is recalling certain 2005-2011 4Runner, Highlander, Sequoia, and Sienna, 2005-2010 Avalon and Tundra, 2006-2008 Camry Solara, 2006-2010 Highlander hybrid, 2006-2011 Rav4 and Tacoma, 2007-2010 FJ Cruiser, 2007-2011 Camry hybrid, 2009-2010 Venza, 2010-2012 Prius, 1988-1990 and 2005-2010 Camry, and 1989 and 2009-2010 Corolla vehicles equipped with aftermarket accessory seat heaters with a copper strand heating element. The electrical wiring in the seat heaters may be damaged when the seat cushion is compressed.
Risk: If damaged, the copper strand heating element may short circuit, increasing the risk of a fire.
Remedy: SET will notify owners, and dealers will disconnect the seat heaters, free of charge, and refund the purchase price of the seat heater accessory. The recall began on July 14, 2016. Owners may contact SET customer service at 1-866-405-4226. SET number for this recall is SET16B.
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.
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.
Southeast Toyota is recalling certain model year 2008 and 2010-2013 Toyota Tundra, 2010-2012 Rav4, 2012 Toyota Sequoia, 2010-2011 Toyota Corolla, 2010-2011 Toyota Camry and Camry Hybrid, 2010-2013 Toyota Highlander and Highlander Hybrid, 2010-2013 Toyota FJ Cruiser, 2011 Toyota Land Cruiser, 2010-2013 Toyota Venza, 2010-2011 Toyota 4Runner, 2010-2013 Toyota Tacoma, 2011-2012 Toyota Sienna, 2012 Toyota Prius, 2013 Scion FR-S, 2011 Scion XD, 2011 Scion XB, and 2012 Scion TC vehicles. These vehicles were sold with labels that were outside the allowable one percent of accuracy of actual weight added. Thus, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) Number 110, "Tire Selection and Rims."
Risk: An inaccurate label could lead to owners overloading their vehicles and tires. An overloaded vehicle can result in a tire failure which may result in a vehicle crash, personal injury, or property damage.
Remedy: Southeast Toyota will notify owners and provide a corrected label with instructions concerning its installation. A small group of the affected vehicles will need additonal remedies which are still being developed. The recall began on May 28, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.
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.
Remedy: 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.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
The owner's manual gives the oil and how often to change it. We show oil facts only once we've checked them against the manual, and we haven't yet for the 2012 Prius.
These are searches on those sites; we don't copy or check their listings. Your ZIP is used for these links and never kept.
