2009 Prius died in strange way

In order to talk about the problems in detail, it is necessary to conduct diagnostics, which will give codes of problematic errors.
Without providing codes, various things can be assumed - a breakdown of the high-voltage battery, engine malfunction, low voltage of the 12V battery, burnt fuses.
All these reasons can be found at the bottom of a cup of drunk coffee, but they do not give the picture that will be after diagnostics.

 

All right well you're in La so should be no problem you want to get this little toy called the code scanner one that will work with a Prius there's a whole section here on that pick one buy it and use it you need to read the codes because all the lights are on nobody can read the codes with just their brain reading your description of the red lights it's not how this works once you have the codes that the scanner will reveal to you then you post the codes here and you'll get answers until you're tired good luck sounds like hybrid isolation fault to me there's no mention of anything about the car batteries or anything in your in LA . So it's a very good possibility asara half a dozen other things

 

There are not too many scenarios where you are driving at the car dies, most common would be you running out of gas. Or possibly the car overheated, but you should have advance warning of that

 

As long as it is off and cool check the oil and also verify that there is coolant in both the ICE and inverter loops. Check at the radiator and the overflow tank for the ICE loop, just the tank for the inverter. One reason cars drop dead while driving is because a piece of road debris has torn a hole underneath that let one of these fluids run out. It is a bad idea to try to restart the car until one has verified that this is not the case, as turning on a motor with no coolant is bad, while doing it with no oil is really really bad.
