Took off tonight on wet streets with a temp just a little below freezing. Rained in the afternoon and then cooled down. 2012 Silverado was sluggish going into either auto or 4 high, and the check four wheel drive message came on. Appears to be working now. Is this common, and could the cold temps/wet streets have frozen something up on the outside of the transfer case? If you had a similar experience, let me know!
