    Newbie here! Wished I had stumbled on this forum sooner; just registered yesterday and have question(s).


    I paged thru the "newbie must read thread" (all 17+ pages); great tips thus far e.g. on jumping and towing... Wish I had known about not letting my Prius sit for a long time (more on this later).

    First, my intro.... I have a 2001 Prius or Gen1 Prius. Live north of Berkeley. Bought it used in 2006 and have racked up a total of 115,000 current miles since. I like the thread dedicated to Gen 1 owners.

    Been driving it for 3 years trouble free as a commuter car, have the CA yellow carpool sticker on it and enjoyed ownership till this Christmas (see my questions below).

    Economy slowed down (and still down). Took a 2 vacation during Christmas + prior 2 weeks doing more Webex calls (mandated by my company to reduce travel exp). Prius sat for total of 4 weeks (maybe 5 tops) for the first time in 3 years.

    Finally to the point, discovered after returning from my Christmas vacation, my Prius wouldn't start (sat for weeks).

    Jumped the battery on the rear (being aware of the right polarity) and it would start but check engine light on. Turtle icon also and drives slow. Also loud fan in the trunk area running.

    I would park it over night, and next day it would start again but starter battery just can't seem to hold charge (have to keep jumping the starter battery in the rear).

    Bought a new starter battery @ my local Toyota dealership (newer larger one with adapter kit) - thinking it would solve my problem. Nope.

    It would start, but check engine on and slow as heck.

    Took it to the same local Toyota dealer, read the code and they said, it needs a new traction battery. Cost is $2500. Wow!

    Questions:

    1) Is this the going rate for a replace traction battery plus labor for 2001 or Gen 1 Prius (I live the San Francisco Bay Area if that helps w/labor and parts rate).

    2) I did a search on this forum and read thru someone's post with similar problem on their Gen 1 Prius. Read about how to replace (excellent write up), but concern about the danger e.g. high voltage.

    Question: is there an alternative to a Toyota dealership (indy shop specialing in Prius) in the SF Bay Area someone can recommend; I am looking to save money on the repair. I can try and do it myself by if reason priced shop charge $1500 - rather have someone who knows what they are doing vs DIY and chance of electricuting myself. :)

    3) Confused (don't have the owner's manual or warranty info. Is this covered by the warranty? I read 10 years/150k miles but also read not appl to Gen 1.

    Pls advice someone familiar with the warrany "CA AT-PZEV warranty" and it it applies to my 2001 Prius w/115k miles.

    Thanks in advance!

    First the bad news:

    • they quoted an NHW20 price - the NHW11 price, last I heard, was closer to $3,000 for the part. Labor of $500 is about right.
    • over 100,000 miles - you're out of luck. You can always beg for help from Toyota.
    Now the good news:

    • salvage traction battery packs, $500-$1,000 - it depends upon availability but make sure it is an NHW11. RISK: it might be a FUBAR pack so shop carefully.
    • self-replacment - this is not a difficult task although the traction battery is heavy. The question is whether or not you have a spare vehicle and a work space. Safety is important but with a helper and the right tools, it can be done in 1-2 days without going nuts or risking life and limb.
    We know a lot more about traction batteries from the NHW11 and NHW20. It sounds as if you're not really into self-maintenance so I would recommend looking closely at getting a new battery and professional installation. However, there are some experimental approaches we've considered but only for those who are 'into' such things.

    If you'd like to discuss the other options, you might consider joining the Yahoo Group, "Prius Technical Stuff." But do not think of it as a 'get of maintenance free' option. The traction battery is a major part ... think transaxle or engine failure. It can be fixed but you may also want to look at other subsystems and deciding which way to spend your money most effectively.

    I'm of the opinion that for less than $3,500, you'll have a car that can get excellent mileage for another 10 years or more. However, you need to catch up on any other latent maintenance issues such as: (1) transaxle oil change; (2) inverter coolant change; (3) engine coolant change; and (4) HC catalytic converter linkage lubrication. Individually these are not show stoppers but if they lead to another subsystem failure, it can become a very expensive lesson.

    You also have one other option, the model change to the 2010 Prius. This means the 2009 Prius, the NHW20s, will be going on sale. You may be able to swing a good price on an NHW20 using the NHW11 as trade-in and get a new car warranty in the last and best series of the NHW20s.

    You have options.

    BTW, please get the 'codes' the shop found and post them here. It always helps to have a second set of eyes look at what they found.

    Once again, sorry that you first PriusChat post was an 'issue'. As you are in the SF bay area I can suggest 2 indie hybrid shops to visit. Art's Automotive n Oakland and Luscious garage in SF itself. Try the phone first if you need to pick just one. Please tell us what they find and post again. Good luck.

    Yep, those are the two best known hybrid specialty shops. Here are the links to their websites in case you can't find them:

    Art's Automotive
    Luscious Garage | Hybrid Specialists

    I've been busy at work - apologize for not posting sooner w/my decision.

    Thanks bwilson4web for listing my options; very helpful info.

    Now that I found this forum for support/info - I am ready to do the other mainteance e.g. transaxle oil change... even though my first post was a problem (ain't usually the case! :)).

    And thanks tochatihu for your suggestions (indi shops); I like working with indi shops especially when folks like Drees 2nds that.

    And Drees thanks for the link to Art's Automotive n Oakland and Luscious garage in SF websites.

    The Prius has been parked in my garage since, and I've been using our spare family car.

    I've decide - now that the tax refund is in bank (although I am not willing to give all my money to the dealership) - I'm leaning towards buying a new battery and doing the replacement myself.

    First I am going to check with the two indi shops noted, and see what they say - I am either going to:
    1) Buy the new battery myself and install it myself (leaning towards this).
    2) Buy the new battery myself and have one of the shops noted install it (if labor is not to much more and shop is willing).
    3) Have one of the two shops to acq the new battery and install it (again if their pricing is not much more than if I were to buy the battery on ebay and DIY).

    Apprecaite all the help/suggestions; I will post the end result.

    By th way (last question for now), where would I buy the gloves suggested in the Prius batttery replacement guide? Special gloves is recommended when handling the high voltage traction battery.

    Also I popped open the rear of my 01 and can see the traction battery - thing is huge - I am going to ask my brother in law to help me. In the meantime, I will need to find gloves if I decide to DIY.

    Thanks again! Cheers!

    If you google high voltage gloves you will see what I saw: expensive. Without trying to dissuade you from this sensible safety precaution, let me say that removing a HV battery assembly intact (but with the safety plug removed) will not expose you to any chemical or voltage hazards. If you see corrosion on the metal case then we have to think about potassium hydroxide and a possible electrical contact pathway.

    You already realize the the other safety hazard of the HV assembly. It is heavy and could cause a major backache.

    Suggest you talk to the indy shops and see what they have to say about batteries from salvage dismantled Prius 2001-2003. In particular, their ability to confirm good module voltages.

    If you have not done so already, remove all the 'trunk felt' to get a better view of Mr. HV and his orange safety plug.

    The $200 battery 'bounty' from Toyota would basically cover the price of gloves :)
