    For the first few weeks I had the car, a dead 12V battery was almost a daily occurrence. I went through all the normal courses of action, and reached the conclusion that parasitic draw was highly variable and unpredictable. The best solution I found was a battery maintainer, plugged in every time I was parked near an outlet.
    The absurdity of this problem, which should escape no one, is that when the 12 V battery falls to about 11.5 volts, the car is disabled with a message, "battery too low" and your only recourse is a boost or a service call. This is absurd, considering the large amount of reserve power in the hybrid battery. Most people would not expect this.

    There is something wrong with your car or the 12VDC battery. You need to fix this.

    I had a 2006 car that I passed down to my Son as his first and started having battery problems with it. I took a good electrician at the dealership to find out it was the car's "factory" amp shorting the hot batt buss to ground.

    Mods don't fix broke.

    I ruled that out the first week with the dealer, It tested well within factory specifications.
    No critical thinking skills or just poor reading comprehension?

    ...and you wonder why you are getting negative returns? I wish you the best with your vehicle. I'm clear all actives. You have a nice day.

    Excuse me for responding to your post, but it was dumb.
    I can't help you with that.

    Toyota will not be offering a retrofit like this for your 2024 car. It will not happen.

    If you want this incorporated in new Toyota models, you would be better off contacting Toyota directly with your idea. I do not think that anyone at Toyota Corporation is reading PriusChat looking for ideas for future models. Posting this idea in the forum is not very productive.

    Opinion noted.
    But not for much.

    This is another one of your many threads and posts that you create because you seem to enjoy arguing with people and wasting people's time.

    I knew I should not have been suckered into posting in this thread. Shame on me. It will not happen again.

    Fred's House of Politics is where he wants to "play". This kind of behavior is encouraged there.
