Hi All! New owner here - 2007 H3 Boulder Gray - Lux Package.

Newbie 4X4 Question:
While normal driving (4WD - first button on the left lit) and taking a tight turn, the thing switched into 4WD High Lock all by itself!

Is this normal or do I need to see the Hummer man?

Thanks.

 

I have never heard of that happening...better take it to the man!

 

are you sure that your fully out of 4 lock? put it in normal daily driving 4x4 and make a few 5-10 mph donuts in reverse, this will kick it out of 4 lock, you should be fine after.
