A warning light stating "service 4wd now" appeared on my dash of my 2003. Chevrolet avalanche. According to the owner's manaul, this indicates that there is a problem with the 4-wheel drive of my vehicle.

My vehicle is now stuck in 2wd and gm does not know if or when they will be able to remedy this defect.
