No takers so far

but a little humility goes a long way

 

If it drains it in two hours a high school kid with a meter could find out what device was sucking up amps.

Something is seriously wrong with the story we are hearing.

By the way why are we hearing this months long rant? Toyota Corporate has a team of customer support people to step in when a legitimate issue is presented to them.

On top of that, there are lemon laws that would refund the purchase if even half of this story actually happened.

One has to wonder how important "drinks" are to the situation.

 

The answer you are looking for is not on this forum...at this time. We all understand your frustration, but playing the soldier and/or victim "here" will solve nothing at this point.

So I'll take one more stab at this. Did your Dealership/s Service Department/s duplicate the standard use where you stated the battery depletes to the level of needing a jump?

 

He has messed up the cut-in and cut-out voltages of his battery isolator, and his cooler is constantly draining his primary battery now.

One of two things is true:
1) You installed a device in your car which is causing a parasitic draw
2) You need a new 12V battery

 

In fifteen years of Gen III Prius ownership, my battery has never worn down. I replaced [email protected] battery once only, after ten years, just as preventative maintenance.

So, yeah, your car has a bad battery or a parasitic drain and it’s probably because you messed something up, because that’s the cause of 99% of parasitic drains.
