Well, this is interesting. Doing some light driving in all electric mode, and saw that my oil temperature spiked just a little bit. It stayed at 419 degrees for the remainder of the drive.
I’m guessing this is a bad sensor? Surprised the check engine light did not come on.
one bit of irony to all this - I once owned a new 2010 JKU. Damn thing stranded me on the highway a year into ownership, due to total shutdown from “hot oil” transmission fault. Oh sweet memories…
