    Please,

    Don't spend the $5000. Spend about $30 (my local fee) for small claims court. Even without a lawyer. Judges vary but I think you have a much better than 50% chance that the judge would be good for you.

    Ditto. I think they are definitely on the right track.

    I got a question, has the dealership offered to buy back your car? My theory is that maybe they are hoping that you will let them buy it back (on the cheap) so they can resell at an inflated higher price.

    Hi Ginny,

    Sorry to hear that Toyota will not help you here. You've previously raised the possibility of seeking local media publicity. Since you did not provide followup comments, I assume there is no interest on the part of your local TV stations and newspapers. You've also consulted with your attorney and determined a low probability of success with legal action, and I agree with that.

    Since you managed to get the car released from the first dealer, I assume that you either paid the towing fee or else the first dealer waived that fee.

    Now that your car is at the second dealer but that service dept cannot help you, you have two alternatives: pay $5K to have the car repaired at the second dealer, or find an independent Toyota mechanic who is willing to take on your car as a small project, retrieve the diagnostic codes that currently exist, and if the inverter has failed, replace it for you. The mechanic can download Toyota repair manual info at techinfo.toyota.com

    Champion Toyota (Houston) sells a new inverter for $2,646.
    Champion ToyotaWorld

    Also, you may be able to obtain a salvage part for ~$900 or so.

    I think there is some possibility that the inverter is good, as I do not recall your saying that DTC had been retrieved after the fusible link assembly and the 12V battery had been replaced.

    Good luck.

    If Idaho has a lemon law they're trying to avoid it. That's why they won't let the second dealer touch it. If it's defective, she should have to pay anything.

    Did you tell other dealer that the battery had been jumped backwards. The reason i ask is when the first dealer replaced the block and 12volt battery, another dealer would only see a bad inverter and not have a logical understanding of the events that took place earlier and based on the fact that those parts have been replaced it would look strange to them. Once they checked with there tech people at toyota they will find an open case with toyota and it will be out of there hands. My brother told me last night that you will probably just have to have it repaired and go from there. When i asked him about the first dealer he told me that they can't make replacement decisions on high dollar items without consulting the regional reps. They request info, and then toyota reviews it independently. So if they saw the 12v low or dead, with low mileage, the fuse block needing replaced, and the inverter bad, you are pretty much going to have to pay for the damage. He said dealers in general don't mind if it is warranty work vs. customers paying the bill, as they make the same amount of pay for the work. So the dealer does not control the factory decision but are rather the middle party involved with the decision.

    I think you are just in a situation that can't be won! Hate to say that after all of the work you've done to this point, but it seems to be a reality.

    I forgot to mention about the 12volt battery. He said it's not that the battery is necessarily dead, but rather that they are proned to going dead for many reasons. His dealer will cover a battery that won't take a charge, due to many reasons for human error. The battery is just small enough to not like frequent charging via driving. So the battery being bad or defective are not really the case. How often have you been driving this? You mentioned jumping had been done before. I think i mentioned before but don't remember for sure, if the battery is low, and the vehicle or whatever you are using to jump can't have to high of voltage or any form of spike. He said it's like when the power company has a power spike and your plasma gets fried. You must be cautios. I can tell you this much after i read my owners manual, i won't be jumping mine either, i'm going to just take it to my local toyota dealer.

    sorry ginny

    Thanks Hybrid boy......I seem to be in the middle of a power struggle with the District Rep and he is not going to back down. It's a sad day when we have to have our cars towed 85 miles (in my case down a windy mountain road so takes 2 plus hrs one way)to a dealer because of a low, or dead battery that is 1 year old. The tow was $400 and could have been a lot higher. So remember you can't just take your Prius to the dealer, you have to have it hauled on a flatbed. This is definately a terrible design flaw. Luckily I was at home and not on a trip or out in a campground with no services. By the way I only jumped the car twice all on the same day...that is it...it started the first time, and not the second time.....never attempted it again except the town truck driver tried it before he loaded it on the flatbed. Car is one year old with 5000 miles on it.

    Patrick, you are right new dealer is stopped from checking my car, even though it has been said many times by different people and the new dealer themselves that I am entitled to a second opinion. You all advised me to have the car sent to a different dealer for a second opinion. I finally was able to get it moved to a new dealer only to be denied a second opinion. ( yes the old dealer put in the battery "under warranty" and waived the tow fee). I am dumbfounded as to why the new dealer can't test to see if a new inverter is needed and to make sure the old dealer really did put in a new fuse and new battery. The old dealer is now saying that back the first week of May they replaced the fuse and battery, even though I have a recorded message on my phone where the service manager says he has the "parts" and is just waiting my authorization to put them in (which I never have done as I always asserted it should be under warranty). And on June 18th when I talked to him about putting in the battery and fuse so they could check the inverter he indicated that had not been done yet and he would see if he could have that done under warranty. That's when they finally admitted the battery was defective and that it should be replaced under warranty. I then said well make sure the fuse is covered also so you can test the inverter for reall He was to get get back to me on the new codes. I specifically asked that he make sure the codes are reset to zero before testing. The dealer operations manager and district manager say the test coeds I got were after they replaced the battery and fuse.

    How long does it take to do the test any way. Isn't it a 15 min. job to retest once the new parts are in ???????? Why would the second dealer be banned from doing a new test on the car????????? What are they worried about or should I say what are they trying to cover up. hummmmmmmmm

    It's what are they trying to cover up.

    Have you talked to a lawyer yet?

    You did say your state has a lemon law. Your car qualifies.

    Ginny,

    How long did you let it run when it started the first time? I'm just wondering if the 12volt didn't have enough time to recharge. Possibility that wasn't charged enough so you had to jump it the second time.

    I sense that your frustration is not how it happened but rather the way you feel toyota has helped? Or do you feel frustrated with the design? I know as a prius owner myself, i love the vehicles, but realize they have a lot of technology behind them!

    Keep me posted of what you decide to do! I will visit the thread as often as possible. I don't want to see you abandon the Prius Nation that we need to help others understand. We just simply have better cars =) PLUS THEY ARE FUN TO DRIVE!!!!!!!!

    (not making fun of your situation, no pun intended)

    The TV station did a spot on hybrids, but were not specific to me or the dealership, just said beware of expensive repairs........that is the society we live in.....white wash everything so as not to step on anyones toes.

    Called a few lawyers, all wanted lots of money up front. I refuse to do that.

    I read the fine lines on our lemon laws (the senior legal aid mislead me when they said dealers have to keep the cars in running condition for two years) fine line says there has to be 4 repair attemps within 2 years.

    At this point I have my back against the Toyota wall..........the old dealer would not even entertain buying my car back. Have not asked the new dealer yet. Will try that as they could get it fixed at cost and should be able to sell it at a good profit. Otherwise I have to come up with the cash for the repair and try to sell the car myself. I live in a mountainous rural tiny town...........no chance to sell it here. Don't know what I will do. After this part is resolved, I may take the original dealer/District Manager/and Toyota Headquarters to small claims and try to recoup some of my loss. What ever my loss it will probably be over $8000-9000 before I am done. You can be sure I will never buy a Toyota again...............I can't trust them. I am glad the rest of you have not had to call on your warranties as they are probably not worth the paper written on. I just can't believe this has happened. They refuse to admit that a low battery could cause the short to the inverter. Good posts that suggest the low or defective battery caused my problem because, only the 100A fuse was blown and no others...no dome lights, not even the 120 amp fuse......also suggests I did not jump the car backwards because it started once, and no other fuses popped.....see post for the possibilities that the car was somehow defective or prone to failure under a jump situation: 20,56,103,135,143,152,155,192,199, and hybridboy's brothers info a few days ago.

    You could have the new dealer fix it. And specify a list of what you want done according to all of the posts in this thread. You want a detailed report of every code, every replaced part, everything they do. They are NOT to just replace the inverter and bill you. They are to fix the car according to a set diagnostic course. And only bill you for what is really wrong with the car. That way you don't pay to replace an inverter when the only thing wrong is a fuse. Talk to the dealership where the car is now and negotiate a repair based on fixing what is really wrong with the car, not just what the regional manager says to replace and bill. See if they'll work with you on this.

    Personally, I'd rather give $4,000 to a lawyer than that crooked dealership.

    Plus whatever settlement there is most likely will also cover your legal expenses. Usually a lawyer will only make you give them approx. $1000 up front and then wait until the settlement / judgement. In my opinion there is very little chance that you would lose this, and second most likely as soon as you have a lawyer file a suit they will immediately make an offer to fix for free or at cost.

    Ok New Day New procedure.
    New dealership service manager drove my car around the parking lot. I said how can that be. I asked for a new test and she got permission to do it. Tomorrow their mechanic will disconnect the battery, reset the codes to zero and drive the car and see what codes come up. She said there were codes showing when she drove the car so not to get my hopes up yet, but at least we will beable to get a new test and know that the codes were set to zero. Their mechanic is as curious as I am to see what happens. Cross your fingers, arms and toes for me............

    and how freaking hard was it for them to do this in the first place at the original dealer... without putting you through a wringer...

    good luck!

    That's great! If it is possible to drive the car although warning lights are on, then the inverter may be OK. It's really unfortunate that it took two months to get to this point - due to an unusual combination of incompetence and rigidity demonstrated by the first dealership's service mgmt and staff.

    If the DC to DC converter in the inverter failed, then the tech should retrieve P0A08, P0A09, or P0A10 fault codes. The fail-safe chart in the repair manual indicates that the car can be driven normally although these codes appear - so the car may be relying upon power from the 12V auxiliary battery, while it is being driven in the parking lot.

    Good luck!

    The car drives?

    Great. Glad the new dealership is working with you. They are scoring mucho points on this. Even if they're farther away, I hope you consider giving them your business over the previous Stealership.

    Patrick, so are you saying that the inverter could really be bad, but the car is made in such a way that it can drive on the 12V battery.

    If that is true, the inverter could have been bad way back when, and the battery may have burned up was because it was doing all driving.

    Back to what came first the chicken or the egg.........

    If those codes come up tomorrow....is there any chance that they might go away if the car is driven a long while.........or are the clear cut....."dead on" codes no pun intended.

    Hi Ginny,

    The DC to DC converter's job is to maintain the 12V bus voltage at ~13.8V when the car is READY. The 12V bus powers various electrical systems in the vehicle and also charges the 12V auxiliary battery.

    If the DC to DC converter is not working, then the 12V auxiliary battery can power the vehicle for a short period of time. However the voltage that the battery can produce will be lower than 13.8V, which will cause various ECUs to log DTCs and instrument panel warning lights will come on almost immediately. The skid control ECU is especially quick to notice when the 12V bus voltage is below normal.

    Therefore, you'll have plenty of warning that something is wrong. You cannot be driving around for hours in this condition - 20-30 minutes is probably more like it, before the battery discharges.

    No. If the P0A08 - P0A10 codes return after the hybrid vehicle ECU memory has been cleared, then the DC to DC converter is definitely bad and the inverter will have to be replaced.
