Just found this thread. My HH 12 volt drained on me over the Holidays while I was home on vacation. My fault, door left ajar. But, since then my mileage has decreased from mid 26 range after winter gas changeover to 21 range. It has been almost a month now and it has not seemed to "relearn". Planning on at least calling the dealer to see what they can do.

Took my HH in and had the Idle Speed Control Reset. Their service note said that it an afffect: Fuel performance, lenght on time ICE runs, and also Transmission gear clatter.

Will watch my MPG for the next month or so and see if it goes back up.

Here's just another owner's experiences to add to the info.
 
I travel quite a bit for work, and while I'm gone my 06 HH AWD Limited sits in the driveway of my house under a carport to keep the leaves off of it. It's exposed to fairly mild weather (mountains of northern California). There's nobody to start it when I'm gone.
 
I just came back after 17 days overseas, and the HH started perfectly the next morning, as it always has when I've left it. Apparently some of you have had other experiences, but I haven't had any troubles due to lack of use of the car. The battery isn't new--the car was delivered to me in March 2006 so it and the car are now 14 months and 20,000 miles down the line.

Warning about Options Issues from a dissatisfied customer by newsman2

Just a note to all thinking about buying a Highlander Hybrid. We are in New Brunswick Canada and ordered a new HH months ago. We ordered a base model and after investigating options, ordered the Navigation system for it's voice activation and hands free telephone capability. Vehicle arrived without a roof rack, which renders our Yakima Rocket Box useless, navigation system isn't voice activated and Bluetooth hands free phone capability non existent, because there was no microphone installed...Apparently, dealer installed NAV systems don't have the capabilities factory installed systems do...but no one at the dealership mentioned that when we ordered, apparently we were supposed to be aware of that complication. We also ordered the comfort package which is supposed to include an integrated garage door opener, that was missing as well. Toyota dealer won't do anything says it is a Toyota Canada problem. Toyota Canada won't return my calls...to make matters worse, the NAV system installed by my dealer came complete with someone's personal phone numbers already entered, so it appears they installed a used Nav system in my brand new vehicle and charged me new. In 3 days I am returning the vehicle to the dealer and demanding my money back. By the way, the vehicle is a beautiful machine to drive, above listed disappoints excepted.

So let me get this straight - the HH should get more than 22 MPG and if it doesn't, the dealer needs to fix something? And I am not the only one to have the car not start when it's been sitting for a few days, unused? You can not imagine how vindicated this makes me feel. After two business trips where I arrived back to the airport late (like 10pm) only to find my car battery dead, and then to have the Toyota tech tell me that they left the car alone for a day and it started so there's nothing wrong with the car, it's all in my head. Well. You can imagine.
 
Two questions - 1) what do I need to ask the dealer to do to get the mileage up on the vehicle??? I am a new owner (purchased in Dec. 07) and assumed that the mileage we were told was just a lie - now I read that it should be closer to 30 MPG - I am thrilled if that is in fact the case. 2) you state that the only thing installed in the car was an after market DVD - did Toyota install this for you? B/c if so, that is the exact same thing for me. And let me tell you - after the first time of the car not starting I check everything in the car before I leave it for any period of time, so at least for this second time, I KNOW that there was nothing on in the car (no lights, not even my cell phone charger plugged in), yet it still died on me.
 
Any advice? Is this perhaps a manufacturers defect that should be recalled?? I am about at the end of my rope, so any advice would be extremely appreciated - thanks!!

Please call Toyota to report dead battery issues!!!! by llbonner

After filing a report with Toyota regarding the issue of no power after leaving the car off and untouched for a few days, I was told by Toyota that all who have experienced this problem should call Toyota at 800-331-4331 to report it, as if it is indeed a widespread problem, they need as much info. as possible in order to report back to the dealers and possibly issue a recall.
 
Thanks!!

We own the '06 HH and I can only discuss issues related to your question (1). All these may or may not be valid for your '08 HH.
 
In the '06 version, whenever the little 12V battery is disconnected or loses power, the idle speed controller loses parameters it needs to more efficiently run the engine. There was a tech bulletin asking shops to reset the controller if they touch the 12V. A shop will reset the controller so it can relearn the characteristics of your specific engine and adjust various parameters to run at what it believes to be maximum efficiency. During this time, your mileage will start out poor and progressively improve as it learns.
 
Another possibility to the low mileage is break-in. We babied our HH for a long time and the mileage kept improving over the first 2000 -> 5000 -> 7000 -> 12000 miles. It has now settled to 25-26 MPG given our normal driving style, our terrain and our traffic characteristics (lights, stop signs, traffic volume). If I am extra careful, I can get 27-28 MPG.
 
Hilly and mountainous terrain, lots of lights and short stop signs, lots of fast moving traffic requiring a lot of jack-rabbit start and stop or heavy acceleration are all factors that can impact efficiency.
 
Tire pressure can also be a possible cause if they are too low. Tire type too if they are too heavy.
 
Cold weather and use of Winter definitely impact mileage.
  
I understand the '08 version has the "EV" button that changes engine performance to favor fuel efficiency? May be try that mode?
 
The '06 HH is not a magic car that can instantly get stellar mileage. The '08 HH is much better, from what I have read so you should theoretically see better mileage as things break in, weather warms and so on.
 
Good luck.

12 volt Starter Battery issues by toyotax2
May 05, 2008 (9:31 am)

We got a HH November 2006 so it ia 2007 HH and love the car. The only complaint is that the battery under the hood that provides the power to the accessories and the ability to start the car dies. Our first one lasted 6 months before we saw issues. We took it into the dealer 10 times and had it tested each time and they kept saying it was fine. We carried a battery to jump the car in the back and had to use it 3+ times a week to jump the car to get it started.
 
Finally I dropped off the car at the dealer and told them to keep it until they changed the battery or gave me a new car. It took 3 days of them calling saying what do you want us to do with the car. Finally they tested the battery after they stressed it and it died for them also. They put in a new battery and we have gone 4 months and the battery light has started again. Has not gone dead yet but every now a then we get a service battery light. I fought with the Dealer and Toyota for months dont want to do it again but, I will.
 
I think they undersized the battery in the HH and should have run an emergency wire from the main battery's to the mini battery under the hood. It would be nice to not be stuck and able to press a button and get temp power from the huge battery packs under the seat to get going.
 
TOYOTA are you listening you undersized your battery in the HH.
 
Anyone else had a similar experience.?

In the old days, a battery that wouldn't keep a charge could mean a bad alternator; if the HH has something like an alternator. Depending on your mileage, this should be warranty work, i am surprised the dealer and Toyota would balk at fixing this. Our local dealer has been very good at responding. Try a different dealer?
 
We got our 06 HH around August '05 and the original 12V still works fine. The 12V has a little window that shows different colors. Blue is good and it has been blue all this time.
 
Good luck and let them know you post on-line so a bad response could easily spread like wild fire on-line. May be that will get them to at least do the warranty work.
