I had the same thing happen when we had a spell of cold weather. I got the warnings, drove about 100ft. turned it off and back on and the warnings were gone. It's happened two or three times, but it hasn't happened in about 2 months. I should probably take it into the dealer to check it out.

Yep, tried that, the 4lo button illuminated, but I did not hear it engage. Locker just blinked.
Cycled start about 6 or 7 times throughout the day. Still had the message on the DIC when I dropped it at the dealer last night.

Mine was doing the same thing and the dealers ended up replacing some module... Once I get home from work, I will pull the paperwork and see what was actually replaced to fix the problem... It was covered under warranty....

ey thats weird. several weeks after i got the mesasges and having the abs encoder module changed my brake lights went out too. They said the switch shorted or something like that, but it didnt write any codes, i found out when parking in the garage and seeing no lights. how come you got codes.
