Dirk - I don't know a whole lot about the Prius, and the battery expectations. But the way it runs ... the electrical system and the gas system more or less run together. So even if the batteries were weak, I would imagine it would just put more load on the gas system.
I remember in my days at Toyota, I seem to recall them calling it a "hybrid assist" system. I wonder if the batteries were mostly dead, maybe the car would still run (but probably with warning lights / messages on the dash).
MetroMPG - On my 2020, one day I fired it up and started to back out the driveway, when one of my sons came along. I wanted to say something to him and I thought it might be a long conversation so I turned off the engine. The conversation didn't take as long as I thought and when I went to re-fire the engine, it wasn't too happy about it. It took much more crankover than normal. I know this was the cold start, shut-off, refire issue. Any thought they might have figured it out on the 2020 is out the window, it still does it. It is an interesting quirk. And yes ... it does act like a flooded engine. My wife's Matrix, when the purge solenoid went bad, would not want to fire up after getting gas (the purge valve would stay open and filling the tank pushed vapors into the intake). The Mirage acted very similar to that Matrix flooded engine scenario.

7milesout - thanks for confirming it's still an issue. That's disappointing though.

On the Prius forum (a long time ago), they had figured out how to replace the batteries themselves for 1/10th the price of the stealer. That was the original Prius, maybe the 2nd gen. So by now, it should be even better.

Chris Fix on YouTube has a video on how to replace the prius battery, I think even I could do it.... I would invent new swear words but I could do it. This forum has so many helpful people!

Dirk, I have 237,000 miles on a 2012 Prius C that still rocks the original battery, engine, trans, etc. Usually it's time that kills the battery, not mileage. I expect the battery to last another year or two before going bad and then I'll replace the battery pack with a used one from a later wrecked C to keep it going until it's usefulness for the purpose I bought it for expires.
