my powered Tailgate stopped working

Took it into the dealer today. After 5 hours they gave up and told me I'm going to have to come back another day. They'll get me a loaner.
All for a pickup truck tailgate on a new truck with 3,000 miles. This is the current state of Toyota it seems

 

It would be very interesting to see if there is a retro-fit option to an unpowered tailgate available

 

Potential TIP alert!

Since the dealer looked and couldn't figure it out (had been rescheduled to dig deeper), I happened to switch on the inverter for my kids who wanted to charge something. Upon stopping at the destination and letting the tailgate down, a "happy drop" sound chimed instead of the "not good drop, good luck to you" sound.

Sure enough, tailgate power up has been operational since.

So tip for the tailgate, if it stops going up try kicking on your inverter to perform a reset.
