In owners' own words
My 4 year old Toyota Prius lost engine power on the freeway on two separate occasions. Driving in stop and go traffic on freeway I heard one beep as the car lost engine power slowed down and went to battery.
Car's engine would not shut off. Additionally, the digital dashboard (Which shows the speedometer, odometer, gas gauge, etc.) would not light up.
I was driving on a highway 95 south, almost to delaware, at night in the rain, after 4 hours on the road, everything stopped working.

Recalls for the 2006 Toyota Prius: 6
The affected vehicles have a steering intermediate extension shaft assembly built with metal splines that complete the connection from the steering wheel to the steering gear. These splines may have been manufactured with an insufficient hardness. Over time, the splines may wear and eventually fail resulting in a loss of steering ability, increasing the risk of a vehicle crash.
During manufacturing, a scratch may have occurred inside of the electrically driven water pump at the coil wire. The coil wire may corrode at the scratched portion. The corroded coil wire may break and the water pump could stop.
These vehicles were sold without the requisite load carrying capacity modification labels. A driver may overload a vehicle which may increase the risk of a crash.
The accelerator pedal can get stuck in the wide open position due to its being trapped by an unsecured or incompatible driver's floor mat. A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death.
The intermediate shaft and sliding yoke in the electric power steering system can crack when large forces are applied and the connection may separate or the sleeve may fracture. This could result in a loss of steering control of the vehicle.
On certain vehicles, due to improper assembly of the air bag inflator, which is used in the side air bag, the curtain shield air bag, and the knee air bag assembly, some inflators were produced with an insufficient amount of the heating agents necessary for proper air bag deployment. This may increase the risk of injury to the occupant in the involved seating position in the event of a crash.
