2017 Won't start, reboots with a clunk

49k miles, less than 18 months old.

When I turn the key to ON, I get a long diesel preheat notice, which is odd because it's not cold. Then when attempting to start, I get a clunk and everything goes out and reboots.

It did this a few weeks ago. On the sixth attempt, or so, it started and has been running fine ever since. Though being more watchful, I think a couple times, the radio did a much longer boot-up than normal.

Could this be just batteries? Already? Or something bad?

Is it okay to attempt to jump start these computer-driven pickups?

My 2010 has done that a couple of times to me. My issue turned out to be batteries...
