If I had had the expectation from the beginning that 150K was about what I'd get out of it, maybe I wouldn't be feeling so shocked at this point.
Though, actually, it's not the fact that the battery has to be replaced that's so shocking, but the actual price tag!
Have them replace the unit and you should get an additional 50,000 to 80,000 miles out of your Prius......... I bought my 2001 Classic from Carmax on March 31st, 2007 and drove it over 500 miles in 3 days.
I was wondering what the replacement cost would be myself.
I didn't find anything on cost, but did see that Toyota expects them to last 150K miles based on bench testing. I kept the all the original paperwork that came with the car and everything seems to say the warranty on the Hybrid system is 100,000 miles or 96 months - whichever comes first.
This time when the lights came on they said the codes indicated that the computer controlling the battery needed to be replaced and most likely the hybrid battery as well.
The full cost of the replacing the computer and hybrid battery is 00!!!
