Vegas to Reno via Mammoth... then the problems started

Good morning everyone. Here is my story, I am thinking steering position sensor, but a little insight would be appreciated.

I was driving with the wife from vegas to reno with an overnight stop in mammoth lakes via 395N. For those unfamiliar it is a mountain road and has lots of turns and elevation changes. Outside air temp varied from 95 - 37 degrees through the legs of the trip. About 20 miles from the overnight stop while climbing the hill into mammoth lakes the ESP BAS, and SERV 4WD lights came up on the dash. Not long thereafter the ESCOFF came up on the trip odom screen. Vehicle was not acting strange and speed was locked in at 70 MPH. I slowed to about 60 MPH and the lights went off. I remained at 60 until about 10 miles outside destination and the lights all came up again. I figured a sensor was going out, probably due to temp changes in combination w/ elevation changes and complexity of the roads.

Since the initial incident, the lights have been on and off with varying times and speeds. Currently driving on flat surfaces with standard temps for region. Anybody have any ideas?

Extreme temp changes can create condensation and perhaps cause a sensor to trip? I'm thinking overheating too could be a culprit. Climbing mountains in hot weather could cause that too.
As far as suggestions, have the 4WD serviced like it's telling you to do.
