Replying to: katzjamr (Jan 01, 2007 8:48 pm) We too got a HH late '05 and have been suffering with a "dead battery" problem for the past couple months (not the traction battery, but the 12V battery that starts the car). We've had it in and out of the dealer throughout December and I just took it back. One "interesting" comment made to me by the dealer mechanic this morning is that it's a known issue that you cannot let the car sit for more than a day without starting it. For us, if we leave it off for more than a day or two the battery typical dies. The dealer is contacting Toyota and I'm hoping they replace the battery and/or upsize it. Good to hear others are not have the same issue...that they can leaves theirs off for days. The whole idea seemed silly to me. |

Replying to: hh_newbie (Jan 02, 2007 9:41 am) Whoever said this is not an owner and have no clue what he or she is talking about. Ask him to prove it. Most of us owners will not tolerate such limitation and you can be sure the NHTSA would have received numerous complaints if this were true. Our HH sat for a week while we were gone on a trip last Winter. The car was out under a tree exposed to rain, some snow and freezing temperature. I forgot to hook up the little solar trickle charger to the 12V but when we got home, it started without a problem. Are we the only special case? I think not. As long as the 12V indicator shows blue, your 12V is fine. Like all cars, car batteries do die and when they do, we will get a new one and cruise on... |

Just a quick note that my gas mileage is back to normal now which is an average of 27 to 28 mpg. Right after the 12 volt battery was replaced it was close to 20/21, a day or two later it was up to 22/23 and now after a week is back to normal. It appears that the engine computer has relearned properly  Wes |

Replying to: nsxwes (Jan 04, 2007 8:17 pm) Just to be sure, he ran the comment past his Toyota contact who confirmed I shouldn't be having these issues. I didn't realize that the traction batteries actually started the engine...in fact I'm still suspicious. To start the HH when it died, I just put a battery charger on the 12V battery. It takes a good 5 minutes of charging before it starts the engine and there is a load on the charger when I try to start it. Perhaps there is a solenoid it's trying to engage?? In any case, I did have a radar detector installed in the car. I can neither confirm or deny the charger was left on the last time the car died (wife's car) so I just took it out all together. Other than that and a DVD player installed at time of purchase...it is pretty much stock. If it continues to die after sitting for a couple days I'll have to escalate the matter w/ Toyota. For now I'm going to think happy thoughts and hope the problem was just with a radar detector being left on. (Ok, no one wreck my dream...I know a radar detector has minimal draw - but this will be my "happy place" until it dies again )
