984 is how many miles I have driven my new vehicle since getting it. Now I am going back to the service folks for this "Service 4WD" message. I didn't even need this new smart and well informed vehicle to tell me this as I am stuck in Four Wheel high- it make a awful noise being engage in 4WD on dry pavement. While I am not happy, I have read they did a software upgrade and the vehicle I have needs it? I am sure I'll open this up to comments, remarks and the know it alls crying how bad GM products are.
If it happens again anytime soon, I'll join your GM hate camp- otherwise I'll chalk it up to new model, new year, big changes that need addressed.
