Howdy folks. So as the title suggests. I have a 2010 gs450h and haven't been using it much lately and the other day I noticed the car has no power at all. Puddle lamps didn't come on as I approached the car, and it didn't respond to the unlock button. I opened the car with the key but and tried pushing the start button but nothing. Opened the boot to check the battery and boot wont fully close since there is no power. Checked the battery with multimeter, had plenty of voltage (>14). Tried pushing the start button with foot on the break to see if it there is no voltage drop in the battery, nothing. So basically, car has no power at all whatsoever despite the battery being in good health. Any help would be appreciated.

Check the engines main fuse. Maybe it' s loose or burnt? I hope you find the issue

Are you referring to fuse link or is there another fuse that I should be looking for?

Sorry I do not know much about hybrids! But to me its sounds like if all electrical is knocked off, then I would hunt down the source. You can see with a simple test light or voltmeter if the fuse box, if any of the fuses have power. If they do not have power then I would follow to the fusible link or main fuse location and test that to see if theres power or a break in that link. Im assuming you checked the battery terminals on the battery to make sure there in good shape and not rusted off

Thanks folks, for the suggestions. I ended up taking it to the auto electrical and apparently the agm on/off battery was toast. aux battery was also leaking so they ended up replacing both. all up cost me $900 (Usd)😢. At least it wasn't the fuselink 😐

Nice! Glad you got it diagnosed and fixed. Happy driving!
