2005 Prius dead traction battery

If the 12v battery is original, replace that first. A dying 12v battery can throw strange warnings. Even if the 12v battery is not the original, it could still be the problem. I doubt that the traction battery has gone bad.

 

There's some hope it's just the 12V battery. You can easily test that yourself using the procedure here:

Or use a voltmeter at the jump point under the hood with the car OFF.

If it tests bad, replace it before doing anything more drastic. I would recommend getting the replacement from a different dealer; the first one is a doofus if they didn't do a 12V battery test.

If it tests good I would get a 2nd opinion from another dealer.

 

Assuming this is the right part, I'm not sure why a $2200 Battery would cost $4800 with install...

 

Since NJ had adopted CA's emission standards in 2005, that longer warranty would be applicable on a vehicle first sold and then licensed and operated in that state. It sounds like the car is no longer operated in NJ, and that is the loophole that causes Toyota to deny coverage. See my post #8 below.

Because the OP's dealer is trying to make an exorbitant profit? Suggest the OP try other dealers in the area.

 

I am wondering if I bought my car in PA but live in NY (car registered in NY too) if my battery is warranted for 150,000 miles. However, it's late and I forgot if there is a time period involved with that as well. Isn't it ten years? I forget. Thanks and I apologize for hijacking the thread though my question is similar to the OPs.

 

You could buy a remanufactured battery from ReInVolt
2004-2009 Toyota Prius Hybrid Battery Pack. : eBay Motors (item 130381610461 end time Apr-18-10 09:14:58 PDT)

Assuming the car still drives to NC, they install it for $282. About $1800 total.

 

Looks like you have a 2004 model year car, so the answer would be no in that specific case. Here's some warranty language from a TSB relating to inverter replacement, that may be of interest. I am sure that a similar concept applies to the traction battery except that the CA warranty is 120 months / 150K miles.

You can check the voltage of the 12V using a voltmeter or the procedure at http://priuschat.com/forums/newbie-...g-mpgs-dropping-test-battery.html#post1020264.

 

Good idea to check it yourself. Mistakes do happen. Dealers are sometimes sloppy about properly charging a battery immediately before installation, cables or clamps might not have been tightened,...
