Oh boy... This is bad.

It's very hard to advise without the DTC codes for the warning lights. Once you bring it to the dealer, report the codes here along with any subcodes.

 

A guess would be the HV battery might be going bad. If you are in a CARB state, you are still in warranty for a new one.....FREE. What state are you in?

 

what is a CARB state? Is Texas one by chance? Just to be in the know...

 

I believe this to be the current list. A CARB state warranty for the battery is extended from 8yr/100k miles to 10 year/150k miles warranty.

With the exception of AZ, any year after the Model Year listed is also covered.
MY 2004 California, Maine, Massachusetts, New York, Oregon, Vermont
MY 2005 Connecticut, New Hampshire, New Jersey, Rhode Island
MY 2007 Maryland
MY 2008 Oregon, Pennsylvania*
MY 2009 Washington*
MY 2011 New Mexico
MY 2011, 2012 only Arizona
MY 2014 Delaware*

 

That will be the day!

To the OP, Yes, if you can hear the battery fan running on high, then you have battery overheating issues, which is usual when there is a module failure. It can also be due to a dirty cooling fan back there, but more likely this is another case of battery failure in a hot climate coming a bit earlier than elsewhere.

When parking the car, use window shades. Don't let it bake in hot afternoon sun, as it makes life short for the HV battery. Use A/C when driving to keep the battery air intake cooler too.

 

Maybe normal, maybe not. Need more info.

1. Was it loud enough to hear easily from the drivers seat of was it just whispering so that you had to place your ear up to the duct to hear it? Many people don't realize that this fan runs very often at low speed, too quiet to hear unless you place your ear up to the vent.

2. How hot was the weather and had you been driving a lot of hilly or mountainous routes?

 

Yeah that's definitely a sign of a bad battery. And of course P0A80 pretty much confirms it.

 

don't bite on the dealers replacement price until you've done your homework.

 

But...but...the Prius is the most reliable car in the world. The web forums told me so!

 

HUH?

 

It's best to ignore the comments of Rich12, he's a very mature senior citizen that acts like he's 3. He seems to have been through a lot, you'll have to excuse his behavior.

 

LOL Amazing..

 

Sorry to hear about the issues with your battery...
Keep us updated on your resolution, I'm hoping you don't have to shell out too much cash to replace it!
It might be worthwhile to search the forums for those who've had similar issues, maybe you'll be able to find a good deal on a repair. At the very least, you'll be able to compare repair prices...

 

Try and pick up a salvage pack if you can find one. They are fairly cheap and the install is easy. There are aftermarket rebuilt batteries that depending on your location might work out to be much cheaper to slightly cheaper. Then of course there is always the dealer.

 

I'm so glad I live in the bay area. Prius servicers galore! Sorry about your battery, hope you find a speedy and great resolution soon!
