@rkohlerbend Here is my theory, which might explain your truck, but it is only a theory.
I think most hybrids came with 12 volt batteries which were fine. My truck has not gone completely dead yet, but its resting state of charge (SOC) is always between 12.0-12.2 volts. Over time keeping a 12 volt that low will eventually kill it. Most people think the battery should be somewhere between 12.4-12.6 volts SOC to keep it healthy. The longer this goes on, the less time it takes the battery to discharge and then you find your truck completely dead.
As low as the voltage in my battery stays I assume it will die eventually and I hope Toyota replaces it. But if the hybrids can't keep the batteries charged they will just keep failing. Unless people check the voltage in the battery when the truck is off, they will never know this is happening until the battery fails. As soon as my truck starts the system voltage jumps right up to normal, so you would think it was fine if you never check the battery voltage.
Take it to your dealer and see what they say, although some dealers claim all of this is normal and it is your fault if you don't drive your truck often enough.
