In owners' own words
In motion while accelerating past a slower car. Heard and felt a pronounced thump and lost engine power on busy local thoroughfare.
The check engine light is on; the car has stalled and looses power it needs to have the sticky exhaust gas recirculation valve taken care of.
While driving at ca freeway speed (65MPH) the car goes limp. The accelerator fails to work and even flooring the vehicle makes no difference.

Recalls for the 2011 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.
The affected vehicles may experience compression of the seat cushion which may damage the seat heater wiring. Damage to the seat heater wiring could cause the wires to short, increasing the risk of the seat burning and causing personal injury to the occupant.
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.
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.
