I suspect awd stuck on when going slow and try turning on dry pavement front end shudders and vehicle barely moves. both directions. seem to have no others problems when driving. I would guess that this is sensor controlled, or transfer case stuck? Any way to tell for sure?
Front end on 2004 Buick Rainier
Did you find out exactly what was causing this problem? Did you have it repaired? I am having the exact same problem.
no sorry not yet. maybe awhile before I can. will keep updated

I had the same thing happen and had to replace the motor that controls the all wheel drive--over $900 at the dealership (only mechanic that could fix it).
