System Malfunction - Trailhunter 5' Hybrid iForceMax - Bad Battery Cell?

[entropy]

For what it's worth, a week after I got my truck I left on a two month trip and kept tabs on my truck through the Toyota app and everything was fine. No issues with the battery.

Cool - maybe @Lets_Taco_Bout_It's problem is just a bad battery, which the dealer should be able to figure out. I don't need it most of the time, but it would be nice to be able to watch it when you are away.

Apparently the truck is ready to be picked up. I will upload a copy of the service receipt tonight so ya'll can take a look.

Just found this out, apparently the day it was delivered to the dealer my trailhunter had a dead battery and im not sure if it was replaced or jumped.

It looks like they had to jump it, then tested it, found the battery to not meet spec, and replaced it.

Here is the official paperwork from the service department. Thoughts?

I might have missed it, but did they do anything to address the brake system control module malfunction? They list it as the root cause of the battery failure, then charged the battery, tested it and replaced it.

A few things I don't understand:

1. Why would a deep discharge kill a relatively new battery?
2. Was anything done to stop that control module from discharging the battery again?
3. Does this mean that we will have to take our trucks in for service when the 12 volt battery dies, so that the tailgate will resume operation?

EXACTLY my thoughts. I'm also curious, which issue was the causation? Was it the dead battery that caused the control module failure or was it the control module failure that caused the dead batter? Lots of unknowns.....if anyone else has any ideas, feel free to chime in.
