#101 of 113 '07 Highlander hybrid
Jan 06, 2011 (6:36 pm)
My car wasn't used for the last 5 weeks due to an illness. Went to use it today for the first time and was completely dead. No dashboard lights. Nothing was left on or doors left open to drain the battery, that I could find. My husband put it on the charger for 5 hours. Dash lights went on, "ready" lit up, so he drove it down the drive. Came back, shut it off, and all is completely dead again. Put it back on the charger and the dash lights come on, back dome light, but the icon for the "main battery" comes on and the 'ready' light does not now. Can't move the car. Nothing. Please help!!!
My questions are:
1)Could this all be caused by the regular battery under the hood being bad?
2) Should we take that in some where to get checked out to see if it's good?
3) Does it sound like it's the hybrid battery that is bad since that is the icon that is showing up on the dashboard?
4) What would have caused either of the batteries to go bad in the 5 weeks it sat in the garage?
5) If the regular battery went bad, for whatever reason, would that cause the hybrid battery to malfunction as well?
Thank you for any help you can give.

The same symptoms for my 08. Turned out the battery under the hood died and just wouldn't hold a charge. Changed it, runs great and no problems since.

Thank you for your reply. That is exactly what was wrong with my car. The Toyota dealer had to put it on a special charger and it's been fine since. When I questioned that "special charger" he said that a regular charger would work but it may take a few days to get it to full charge. We only had ours on the charger overnight (still dead) so that fits with what he told me when I picked up my car.
Appreciate you taking the time to let me know "I'm not alone!"

Thank you for letting me know about the inverta problem. I'll be calling my Toyota dealer/mechanic in the morning to find out about that. I'll be getting that extensive diagnostic test while my car is still under warranty. Thanks again!

I have about 1500 miles remaining before my 90K service and my dealer says he doesn't know anything about any kind of "extended diagnostic". Could you please be more specific. Every service that is done has to be accompanied by a code of some sort, and when you had your "extended diagnostic" done your receipt from the dealer must have included more informative data. I would appreciate any extra information you can give. Thanks very much. Chuck
#107 of 113 what's wrong with the battery???
Sep 14, 2011 (5:16 pm)
I went out to start the car this morning and it wouldn't start. I would love some insight if you guys have had this same problem and how you got it fixed (and the cost, if you would be so kind) I have an 06 HH.
When I put the key in, all of the dash lights turn on, but when I try to turn the key over, it says "put in park"-- it IS in park. I noticed that I left a door open last night (oops) and there was a dome light on because of it. After two attempts to turn the car over, there are NO dash lights and the car is non-responsive.
Is this a tow to the dealer problem or wait and it will fix itself or get it jumped and it will fix itself or get a charger on it for a few hours kind of thing???? I would Love some help here.
Thank you soooo much.

Many people other than just me, receive the recall notice from Toyota saying part prone to failure when HH driven at high load has been identified, and will be repaired free of charge. Notice even says that people who have previously had failure should contact Toyota to investigate refund of expenses. Only issue, parts for repair ar not likely to be at dealer until Feb 2012.
#109 of 113 2007 hybrid battery dead vs. deminished
Nov 16, 2012 (11:34 am)
I am the owner of a Certified Pre-owned 2007 Highlander Hybrid, which I had been quite happy with until it crossed the 50k mile mark and the fuel economy took a 20% hit from ~25mpg to ~20 mpg. I took it to the dealer, but the car was given a clean bill of health.
...I suspect however that the battery pack potency has diminished.
The dealer's test are a complete black box, red-light/green light test which apparently even they don't know what determines the result of the test.
...so what I am hoping maybe one of you all can help me figure out, is...
Is it possible to determine how well the battery is holding a charge and how much power it is delivering in comparison to its original (or replacement) specs?
Also, if the battery is some significant percent less capable that it was originally, is there a way to get Toyota to honor the warranty and replace it?
And finally, what is the path for replacing the batteries if Toyota won't acknowledge their diminished state?

When you discuss diminished state, I am assuming you refer to the battery pack ability, or lack of ability to hold a charge. This typically occurs with age.
I am not familiar with the black box go/no go test you refer. Did you actually see the test performed? I do know the service centers will measure the voltage of the battery back to assist in determining the condition. If the voltage is within a specific range of specifications, then it passes. Above or below, then it is deemed a failure. To the best of my knowledge, there is no load test performed which would measure the ability of the battery to build and maintain a charge.
That all said, I do not believe a diminished battery would cause the drop in mileage you mention. I would expect if the battery pack is diminished then you would notice the gas engine starting up much more often than normally.
I notice a considerable drop in mileage on mine in the winter months. From the typical 25MPG down to nearly 22.0MPG.
In your case, I would strongly suspect your problem is a maintenance problem. Air or fuel system maintenance may need to be performed. I am assuming you have done the air/fuel filter replacements. Your next would be to ensure the air intake system is cleaned. I do mine myself about every 50K miles using Gumout products, but there are plenty of quality names in the parts stores. If you are not comfortable with doing it yourself, you can have the service performed for around $125.00. My only caution would be to specify the Teraclean system.
