2006 HV battery failure

That is one of the earliest failures that I have ever heard of.

Since your car will be in the shop for a month, ask that they keep your 12V on a charge maintainer. Otherwise, they will give you some BS story about how the main battery killed the 12V battery too, after they themselves have killed it by letting the car sit.

 

I have serious doubts that the problem is the traction battery but, if they want to replace it, let them.

 

Agreed, I wouldn't turn down a free HV battery with a free rental car; & if that doesn't solve the problem all the better as the car is under warranty any new parts they want to replace will be under warranty. A couple weeks or when my cars have less than a thousand miles of warranty left I go to the dealership and tell them to go nuts, they're more than happy to comply and find every little fault that can be replaced, I get new parts, they get labor paid by toyota, win win.

 

A battery can be completely good one minute and totally dead the next. It's not a common failure mode, but it can happen.

There was another thread recently where the person found out from Toyota that the batteries are on a 4-week backorder.

This is really odd, I wonder if there's suddenly a huge demand for them?

 

My 06 has 158k miles and no issue with the battery.

 

What do you see in Torque for the battery block high and low voltages when driving up a long hill? i.e. battery current is >50A for a couple of minutes. Not that there are many long hills in NYC...

 

Yup 4 week back-order for and If I paid $600 extra they will get it in a week through an expedite order.

No surprise that the demand is increasing. 2nd Gen Prius that were sold are aging every year and need for parts will increase.
Not sure how fast Toyota's manufacturing queue is on these batteries.

Also I think inventory management on this part is complicated as they might not want to produce too many of them and then have them sitting as a sitting battery deturates. (from what I heard)

 

The longest "hill" I can think of is the acceleration and climbing of the Verizonal bridge after the toll booths. The battery doesn't get much work out since ICE did most of the work. I mostly see 0.1, 0.2 or rarely 0.3 volt difference between the high and low. The max delta recorded was 0.5 volt.

 

Sounds normal for a 2006 with 150K+.

 

Where are you reading the voltages to see the variation? Can I see these voltages on my scangauge? Thanks, John
