Soon after getting a recall software update for the hybrid system, the car displayed hybrid system check message and lost power.
Bought this car brand new in 2012 and have always performed maintenance on time.
Driving the interstate at 65 MPH the engine stopped - with no warning of any kind, the air, dash lights, radio, etc all continued to work.

Recalls for the 2012 Toyota Prius: 6
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. If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.
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. 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.
The electrical wiring in the seat heaters may be damaged when the seat cushion is compressed. If damaged, the copper strand heating element may short circuit, increasing the risk of a fire.
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. 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.
These vehicles were sold with labels that were outside the allowable one percent of accuracy of actual weight added. 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.
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. 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.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
