HV battery failed - what to do

I'll let others comment on the codes*, but if they agree this is the traction battery I have two questions for you:

1. How quickly does the car have to be back on the road ?
2. How long due you plan to keep the car ?

I advise you to ask Toyota for financial assistance. They are often quite generous when failures occur just outside of warranty.

Good Luck!

*Addendum
From a wiki on Prius:

 

I would not go for a new battery. I would most likely go the with the best (newest, lowest mileage) salvaged battery with the thinking I can replace it 2-4 times if needed before being at the price of a new one, and then the price is spread out. But a re-manufactured one is not a bad idea either.

 

Not a bad reman price.

Looks like they have installers in Boston too.

Of all the choices, reman is the riskiest and the only one I personally would not consider. If I had the time and could find the local expertise required, I would buy a lightly used salvage G3 Prius baterry off Ebay and have the modules swapped into my case.

For OP, a couple of steps should be done first as I outlined:
1. Verify that this is in fact a traction battery failure. It might be prudent to just replace a 12v if it is older than 3-4 years old and see what happens.
2. Talk to Toyota. If they cover 1/2 the cost then the choice is easy.

 

Definitely worth a try, particularly if your car has the 150k miles warranty.

 

You need to call Toyota USA in Torrance, CA. Speak to Customer Service. They will assign to a local regional Manager. Be very polite.

i would ask them if they would conside helping with some of the cost. all the best!

 

Mention that the problems started while on warranty (Reduced MPG, Gas engine constantly running, car acting funny), you just did not think it was serious. You are a long time Toyota patron, use the dealer for services. You will be making another purchase of a car in the near future and would consider Toyota again. Be very humble. Let them know this will be a financial hardship to pay $3,541 on your family.

Let us know how it works out?

If you get no Credits from Toyota than consider the Reivolt or Gogreen or Scrap Yard option or sell the car unrepaired and move on. Using the dealer for a new battery is just too expensive.

What is the car worth unrepaired and repaired as a trade in. I know this conversation may whip up a firestorm of debate on PC as people weigh emotional attachment to a car and number crunching budgeting. The real decision is should you repair a car with over 150,000 miles on it and not much life span left or cut your losses get some money on a trade in and get a new car. That is a personal decision but one you must come to grips with.

I have in the past dwelled on different options in trading in my old BMW for a new car. However for me peace of mind and worry free motoring is worth a lot to me, enough to make a new car payment which is just a part of my budget a few Benjamin's.

However you car may be OK to repair and drive a few more years but get the best deal you can with the least out of pocket or buy a new car or certified used one with an extended warranty. Best of luck

 

Any update?

 

Good time to prepare your Presentation. Remember be very humble and polite. Present in a Chronological format. Let them know your a loyal Toyota Buyer and are considering another Toyota in the near future. The problems started prior to warranty expiration although you did not report

 

Best of luck.. please..keep us informed..

 

sounds promising anyway.
