Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.

Is your vehicle AWD all the time or is there a switch on the dash to change from auto4x4 to 4high, 4low?

Are all 4 tires the same brand, size, age, and tread depth?

It's awd all the time. And yes the tires are all the same
Expert:  Chris (aka- Moose) replied 1 year ago.

It looks like in your case, prior to doing diagnostics to see which codes are stored, there is a wheel speed sensor issue causing the AWD to engage and this is resulting in the transfer case overheating. Resulting in the warning your getting. Step one will be to scan it for codes and address those codes. More than likely its just a speed sensor reading wrong and to blame for all of this.
