Nhtsa 14v053000/hybrid propulsion system. . . I did not receive a recall notice in the mail. My daughter owns a new Prius and she did not receive any notice either. My car engine did not shut off but my daughter's engine has shut off. You should ask Toyota to show proof of its recall mailings. I'll bet the farm that they can't.

Our 2010 Prius suffered a near total power failure on 5/10/13 when the car suddenly and without any advanced warning, lost power decelerating from about 35 mph to about 4 mph in less than 5 seconds. Every idiot light came on at once on the dash panel and a "hybrid system failure" notice came up on the alphanumeric display. Luckily, I was on a city street and not the highway when this happened. I was able to get the car safely off to the side of the road and call for a tow. Our Prius has approx. 44000 miles on it, is regularly maintained at the dealer, not mistreated in any way and gave no advanced warning indication that there was anything wrong with the electrical/propulsion system. The car lost almost total power, limped about 50 feet past parked cars and just died at the curb after I put it in park. It would light up across the dash, but never start the engine. We have had this car about 36 months. As this is my wife's car, I am greatly worried about the safety of the car and having this problem happening again, especially to her at high speed, multi-lane highway driving. It has been repaired at a local Toyota dealership. They installed a new 12v battery and eventually the main fix, a inverter/converter. The car now runs like day one. However, how do we trust this car in the future if it did not give any warning of imminent propulsion failure ? I am getting nowhere with Toyota about their providing some kind of advanced warning to get the car onto the shoulder of the road and keep it running for about 1 - 5 minutes. Thank you.

Total breakdown of consumer's wife 2004 Prius on September 2, 2005 in san jose, California. The vehicle suddenly lost power while merging into the interstate. A loss of gas engine power with failure of the internal combustion/engine to start, resulted in only electric motor propulsion and breakdown on the highway as the battery quickly went to single pink bar level within a 1/2 mile. Multiple mil lamps lit up. Began to merge onto the highway from a stop speed of 30 or 40 mph and slowly accelerated into heavy traffic. Had to pull off to the breakdown lane of the highway with all of its debris , etc. The dealer completed the repairs at san jose's capitol Toyota on 9/2/05. The dealer fixed the car. But the consumer contacted a Toyota pries advisor who stated if there was a service bulletin for this characteristic that would prevent the roadway failure then why was it not executed during prior services on 3/9/05, 5/26/05 and 6/09/05. This indicated that the car was reliable after the repairs. The consumer, an accomplished engineer, said Toyota knew about software bugs. A software bug did not impair operation until the right combination of environmental factors was reached. All pries had this potential bug that contaminated the electronic control module (echo).

My car (2001 Prius) was at a dealership (marina del rey Toyota) for service. While parked, with no one inside and the ignition off, the main propulsion battery caught fire and burned through the vehicle interior, causing a total loss. Toyota blames the fire on a battery defect.

I did not have a failure, but I had an experience that I think would be helpful to you and Toyota. My experience was accidently hitting my right knee lightly upward against the lever that is used to put the car in drive, park, referse and battery. I was traveling on the highway and was shifting my weight slightly to get more comfortable after I had been driving several hours. Within a few minutes, looking at the dashboard, I noticed the car was in the "b" mode which I guess is called battery. I shifted back into drive with no problem. However my thinking is that if someone did what I did (in the way of accidently tapping the shift lever with their knee) and did not notice that the car had shifted to battery, after driving for some time (x hours or minutes) the batteries that drive the electric motor/engine would run down to the point where the car would stop running and could not be restarted because the batteries were so run down. Also the engine would not start again because the batteries running the electric motor were not assisting in the drive of the car as designed. I noticed a note on a web site this evening that indicated the car would not run when the batteries were below a 20% charge. If this is correct, it would fit in with my theory. The shift lever needs to be harder to move so that accidental changes such as I experienced would be prevented. If this is too expensive, maybe a cheaper way to fix tghe problem would be for an alarm light or audible signal to go on when the battery propulsion had been going on too long unassisted by the gasoline motor. Maybe I'm all wet, but I thought it wouldn't hurt to let you know my thoughts.
