    This is not a happy story. We had a 2006 Prius which had no issues for over 6 years. It was maintained at the dealerships on a routine basis and needed only oil and tire changes. At about 110K miles we had the 12v battery die, then a few months later, a water pump leak and drive belt change. This week my wife started the car to find the red triangle illuminated along with several other warning lights. We took it straight to the dealer who diagnosed the HV battery was failing. Cost to be $2588. plus nearly $600 in labor, and taxes. This was sudden, no other warnings were given. No other solutions were offered by the dealer as far as single cell replacements, as I asked. My wife and I decided NOT to pay the nearly $3500. to replace the battery and eventually traded the Prius in at the dealership. Several months earlier when the 12v battery was replaced, another salesman at a different dealer had told me the prices were dropping on the HV battery and they were ONLY running $1000. This turned out to be totally false, as we had this price replacement checked at another dealership and received nearly the same quote. Moral of the story, beware when the Prius goes out of warranty on the battery! It is a very expensive "fix" and one that you really have to question when the car has this kind of mileage on it. You are not guaranteed 150K, 180K, or some higher number of miles despite others experiences. If I ever buy another, I'll never go beyond warranty on the battery before trading it in. I did not replace this one with a new Prius given this experience! Beware!!

    I was told their "best" Prius tech diagnosed it and that voltage was low. They also test drove the car looking for other indications. They were "sure" it was the HV battery but I did not get specific codes as it would all be Greek to me. They claimed that they won't do single cell replacements as they can't warranty the result and usually it means the battery is on a slide to failure. As we make long trips in the car we were not willing to risk it and were left in an untenable position.

    So you saved over $3500 in gas during those 6+ years over a car that gets 30mpg. Not a bad trade-off.

    If you lived in a CARB state the battery would have had a 150K/10 yr warranty!
    Did you check?

    Yes, overall, not too bad as I got the Prius when things were hot in the market, but I caught a dealership change in ownership, and got a reasonable deal. However, even if you are reasonably well off, nobody should have to look at a repair bill of $3500. for a car. Most can't afford that, and many have no options for other solutions.

    Yes, I checked. Wrong state. I wish I lived in CA or one of the others, but the warning is the same whether it is 100K or 150K. At some point, the clock strikes midnight!

    Listen to Yourself! If you are going to act helplesss and submissive to all the unyeilding "experts" out there, yheah, you dont belong in a revolutionarily innovatative work of Human Genius, such as the Prius, which is ahead of it's time. It needs time to pass to clear the herds of sheeple out of the way of progress.
    The internet does link to numerous sources of used parts for the car, which, if someone can concieve to build, someone can diagnose a part failure, and replace that part. The Dealers want to make retail money. they are like hospitals , where, many clinics offer less expensive car. If you remove the carpet over the battery in the trunk, you may find that the battery should not cost 600.00 labor to replace, I heard there is a place in Denver MileHybrids, that does refurbish, and garuntee batteries for the Prius. Good Luck, Quit the sour grapes wine

    by the way, 110 k times at least a nickel equals 5500.00. Not a bad fund to adress car repairs, which all cars will require.

    Checked prices and found no better than $2100. plus the cost to move, or transport, the car to North Carolina, or elsewhere. Didn't want the time, and added, expense. I'm posting a warning to those that may not have the $3K plus to fix, or want the hassle. All can be good, until it is not!

    We still don't know if the HV battery was really bad in the first place.

    The Prius is not for everyone. This person is similar to any other non Prius experts who know that the main traction battery is a ticking time bomb and when it fails it is for many a day of reckoning.

    Sorry you dumped your car in year 7. Here's hoping whatever you replaced it with doesn't need a tranny, or an engine, or some other expensive repair. The thing to do upfront is to decide how far you are willing to go with the car. Then when that time or that situation occurs you know that it is time to walk away.

    Perhaps if one can't afford a 4 figure repair bill one should be looking at less expensive cars.

    Guys let's be respectful. I would be just as ticked to be presented with such a Large repair bill after 7 years of ownership

    Salvage battery is about $500 plus install. No guarantees.

    If you must rely upon Toyota dealer service installing new parts, then I agree with your new policy to trade the car before the warranty expires. The traction battery is not the only consideration: the inverter and transaxle are two other costly components that certainly can fail after the car has registered six digits on the odometer.

    Clearly, just because some Prius taxis have logged 300K miles without needing major repair, that does not therefore mean that all Prius owners should expect the same. There is usually a range of outcomes with regards to component failure.

    There are alternatives to costly dealer service in some areas of the country, but apparently not where you reside. It is also possible to DIY replace the traction battery with a used battery, and there are several posts about how to do that. Obviously there exists a DIY safety issue if you are not competent to work with high voltages.

    I recently faced this same issue with my 2005 @140k. It is tough to swallow but ultimately I accepted it as a maintenance cost. 2ยข per mile is far less than what I save driving it. I know no one wants to actually have to face the actuality of a failed HV, but there is no way you can't know it is a possibility.
    I don't begrudge your decision, as I considered the same. But the is no way you got a good deal trading it in. In fact I would be willing to bet you would have easily made your money back plus if you had done the repair and then sold it yourself.

    Dang -- I hope the next time a Prius Chat member within 1000 miles of NC has this issue they contact me. I need a good used prius that just needs a battery. the battery is an easy replacement and good one's are $500 or so at junkyard or $900 to $1000 rebult. Much cheaper than a tranny in "normal" cars.
