HV Battery leaking cells?

welcome! judging by your post, i'd say your a candidate for a doorman. it's plug n play. the important thing is to have a local supplier so you can pick up a warranty without a lot of trouble if needed.

otoh, you got your battery out, so if you really want to save some money and have the time, read through the rebuilding threads here and get a mini vci. all the best!

 

Are you out of warranty?

 

az is not carb.

 

Sometimes Toyota has been quite helpful sharing costs in cases like this. We have not had too many 2008 batts fail yet, so this is a little early. I don't know if taking the batt out reduces the chances Toyota might help. But you'd have to put it back in and get the dealer to verify dead batt and go thru the process of contacting Toyota. Takes time and outcome not certain. We tend to like genuine Toyota new batts the best, as the rebuilds tend to fail. Yes I know it is guaranteed but that just means you are in the dead batt boat again.

 

...potentially something toyota would help with. give them a call, and ask if they can help with a new battery.

 

With Toyota helping out, $1400 will probably get you a, New Toyota battery

 

A master warning red triangle by itself is not indicative of a failed traction battery. What does "et cetera" mean - what other warning lights or drivability symptoms are present?

Before spending four-digits, you really should retrieve the DTC so that you know what is wrong with your car. Get Mini VCI.

You would have to move the system main relays and the traction battery ECU from the original to the new battery enclosure, if you buy a new battery from Toyota. This is not required for a reman.

Even if Toyota will not help you, call your local dealers to see what you can buy a new traction battery for, and press for a discount. The incremental cost over the Dorman may be well worth the added service life of the new battery.

 

We have a thread on the goodwill warranty process:
HV Battery Goodwill Warranty Listing - Toyota Prius USA | PriusChat

But so far that was for the whole job of batt replacement not just the battery.

I was just thinking what's strange is we are not hearing batt failure cases from PriusChat users lately, whereas it seems like in the spring they were dropping like flies and I was trying to capture the case histories.

 

DTC C1300 means a skid control ECU failure.
DTC C2318 is a low voltage error (the most likely issue is a marginal 12V battery)
I do not believe that DTC C3010 is a valid code.

Yes, it is reasonable to clean off the corrosion on the high voltage traction battery regardless of the other issues the car may have.

I suggest you take a sharp photo of the warning lights. Also look for a warning icon or message on the MFD. Each one has a specific meaning.

 

what about the leaking cells?

 

Depends upon the rate of electrolyte leakage, whether that is causing a ground fault, etc.

 

thank you pat, i didn't realize there was an acceptable amount.

 

did you car spend a lot of time parked in the az sun?

 

Well - "acceptable" is a subjective concept. If a tiny amount of electrolyte is leaking out of one module and it will take another two years for the seepage to touch the battery enclosure and cause a ground fault, I don't know if it is reasonable for the OP to pay four-digits for a replacement battery right now.

DTC C1310 is posted by the skid control ECU and means the hybrid drivetrain has a problem. However C1300 means the skid control ECU has failed, so who knows whether C1310 is legitimate. The Mini VCI would help to see what DTC if any are posted by the hybrid vehicle ECU and traction battery ECU.

Since the car is at the dealership now, let's see what the mechanic has to say.
