01 - 03 Battery Reseal TSB - should I go for it?

It is hard to say because I've had one informal report that they may have 'improved' the process using epoxy. But I've also seen some photos posted of corroded terminal bars in "Prius Technical Stuff."

Perhaps you could get them to report on the health of all battery modules too.

Good luck!

I would not recommend anyone to disassemble the HV battery unless you know what you are doing and have the proper equipment. Accidents do happen and I don't want to think what would happen if you shorted it while taking it apart. I have always been cautious when working on them. Better to be safe than sorry, .

As for the recall, as long as the tech is trained, there should be no problem having it done. But as with anything else there all sorts of techs out there.

 

Hi Kocho,

I recommend that you have the sealing done. The bus bars will be replaced as part of this service.

Maybe you could ask the service writer to tell you when the mechanic has obtained access to the battery and removed the top cover. Then you can go down & look at the battery to see its current condition.

 

Hi Kocho,

Any Toyota dealer should be able to input your VIN and determine whether mandatory recalls had been performed. However, other service history probably is not available on a centralized basis, as your dealer indicated.

If you are interested in reading about the SSC 40G traction battery recall, it is posted in Yahoo toyota-prius-sat1 files. The file with mechanic instructions is 3MB in size so I will not post here.
