To see if your HV Battery is ok, run your engine while in Park, and watch the display that shows your green battery. It should charge up to all green. Another check, run engine in park for 10 minutes, then shift to drive. The engine should shut off, and it should be powered by electric power at slow speeds, if your battery is in good shape, and charging system good shape too. Oh, need to shut off air cond., defroster, heater, and accesories, and lights before testing.

This is the first serious battery problem that I've read about. I think the 100K mile guarantee has to cover more than one year, If you drove that much, they'd disallow
coverage on the grounds that it was commercial usage.
Try getting a Toyota rep to come to the dealer that was most cooperative.
I had a serious question when my 2004 was new and Toyota sent a rep to Glenwood Springs, CO, to drive my Prius up a long mountain pass side by side with the dealers demo to see if I had a real problem, which I did not. I now have 55,000 miles with the understanding that my battery is still under warrantee.

Sorry, I don't know what caused your problem, hopefully they got it fixed. I live close to, and have driven thru mountains, and live in alot of cold weather,, with no problem as far as mountain driving. I have other problems, not related to high altitude. Cold weather needs a well charged up 12 volt battery,plenty of fuel in the tank to prevent ice forming, and a clean air filter cause of less oxygen.I just learned to doing that from living in a cold climate for many moons, I mean many years. thanks, johnwyo but those two things I don't think, would cause what you experienced with your car.

I apologize, I do not have advice to help. If I could ask some more details, Does the car have greatly reduced power, when it runs electric power only

I would make sure all my tires have enough air in them. Then, if it vibrates at only at a certain speed range,10 to 15 mph consecutive, range,ex. vibrates from 55 to 68 mph, that can be a tire out of balance. Need to have tire rebalanced. You could put your spare tire on each tire, until you find which one it is. Alot of work, but i'm dumb enough where I have done it myself. Or, have a friend follow behind you, and try to spot a vibrating tire. In your steering wheel ,(vibration), then your front tires. I gave you some of the more common causes, there are other causes, but usually occur with car with well over 100,000 miles, and driving thru many potholes, mabey over a curb or two, HA HA anyway, johnwyo I ran over a curb or two in my day.Still do.

My 2005 Prius with 80K miles has done the same thing (same symptoms, always on the freeway) four times starting in Dec 2009. It is at the dealer now. The last time I took it in (Jan 10) this dealer consulted Toyota and they "recommended" replacing the the fuel pump, which requires replacing the gas tank and costs $1000+. The dealer's service supervisor offered that they were not sure it was the fuel pump and suggested driving it in the hope that they could diagnose it with additional information. They did not mention replacing the battery or inverter.

This isnt much help, but it sounds like the Toyota Supervisor was being honest in trying to figure out the problem. Does your check engine light come on? If it does, if you could go by an Auto Zone and ask them to check the code from the check engine light, (for free). I would hesitate to have a battery and inverter replacement. Sounds like possible plan for extra profits. (My personal opinion)

Be careful if you own a Toyota Prius, even those that have not yet been recalled:

#63 of 104 extended service warranty by shay2

Apr 06, 2010 (3:07 pm)

MY 2005 PRIUS HAS 69k MILES. RECENTLY NEEDED NEW WATER PUMP $600 AND NOW NEW ECU $2,000.
i WOULD LIKE TO KEEP THE CAR BECAUSE CAN NOT AFFORD SOMETHING ELSE AND AM AFRAID OF GETTING ANOTHER TOYOTA. WOULD YOU TRY TO GET A SERVICE WARRANTY AT THIS STAGE OF THE GAME? WOULD ANYONE GIVE IT TO YOU? HOW MUCH DO THEY RUN? I AM JUST AFRAID OF MORE THINGS GOING OUT.
THANKS FOR YOUR INPUT

Hi There,
 
I have a prius that has over 177k...at about 151k, I got my inverter water pump replaced as well. That didn't solve the problem, then they told me it was my hybrid battery. Instead of spending over 4k, I found a third party company that provided both the battery and the ECU for only $2400. Now the dealer installed everything for $800 so total was $3,600...and that is with a new battery. I'm not quite sure why your ECU is not warrantied up to 100k? Also the battery is warrantied up to 150k (which I just missed). (TaylorAutomotive.com...just fyi)
 
So...the call is up to you. I actually had to go to four dealerships before they confirmed that it was the battery that needed to be replaced. First dealership was the Inverter, the other was the ECU, the other was a crankshaft sensor....
Not sure what to say shay 2...you should see what the original warranty covers for I got the platinum warranty and everything seemed to have expired just as the warranty ran out. I would simply suggest get a second opinion at another dealership and see what they find out and go from there.
 
Good luck.
