2005 Prius w bad hybrid cell

[magruder]

The HV battery was the one concern I had before I bought my Prius. I stopped worrying after checking ebay, I would get a used battery.

Sorry, but someone whining that a manufacturer of a product won't give them thousands of dollars of parts even tho they're well out of warranty amuses me.

The warranty is 8 years OR 100,000 miles, whichever comes first. If your car were 12 years old and had less than 100,000 miles, do you think they'd warrant it then??


Suck it up and pick up a used battery unit offa Ebay. I'd be thankful that there are enough Prius that have made it to salvage yards to provide parts. For ~$600 and maybe a couple hours of wrench turning, I'd replace the darn thing myself.

go on ebay and get a cell.
you can buy cells not the compleet pack if you dont want to
will set you back just a few bucks

make sure you by a charger for it and charge it to the same voltage as your OEM pack is and then replace it.

I did a rough calculation that my odometer was reading 10% off for every 5 miles. I would use the speedometer check stations and for every 5 miles my odometer read 4.9 miles. So every 50 miles, my car reading was off by 1 mile. This was with stock tires inflated at 42/40. So it seems your car logged 3000 more miles than actually driven based on my figures. You will somehow need to prove that your odometer is off though. Just a thought. Good luck

I don't know why you feel the OP is covered to 150K miles. Their car wasn't bought and registered in a CARB state. Their HV battery warranty expired >50K miles earlier.

A 2% inaccuracy is pretty high and again to me is moot. The OP's HV battery warranty is long gone. In http://www.caranddriver.com/layout/s...er+Scandal.pdf (came from Speedometer Scandal! - Feature / Features/Classic Cars / High Performance / Hot Lists / Reviews / Car and Driver - Car And Driver), Toyota's average odometer variance was 0.7% from sample size of 19.

The OP should get the DTCs, possibly get another opinion and if the HV battery pack is bad should really look into a salvage pack or someone who can replace the bad cells.

I bought a used Prius with failed battery cheap, got a salvage battery fitted it everything looks like it should work but scanguage shows no dtc's to reset and I still have the main batt on display and warning triangle. What could I be missing

What you are missing is that ScanGauge will not display all DTC produced by the many Prius ECUs. If you are lucky, it will display DTC produced by the engine ECU. Since you see the battery icon appear in the MFD then the battery ECU (and maybe the hybrid vehicle ECU) is producing DTC.

Did you disconnect the 12V battery negative terminal for a few minutes to allow the ECUs to reset? If so then maybe your salvage battery also has a problem. Time to tow your car to the dealer so that the DTC can be retrieved.

I'd be more worried about the transaxle failing since that is not so easy for a DIYer to replace.

Does Toyota reconstructs the failed battery module?

It's OK sorry, I had the HV dongle not all the way home, all working now

The have a program set up, in Japan, where they will refurbish old batteries including age and voltage matching replacement cells. This is something done under specifically controlled conditions with the ability to test each cell.

I do not think it is something that shade-tree mechanics should be doing (with rare exceptions Hobbit/Patrick & Doug)

Are the toyota dealers the only people whop can retrieve the other dtc's? Darn I was hoping I could see everything with the scanguage, I have never played with hybrids before, can't you tell?
