I'd like to see ALL of the GM products do this: Kick the vehicle out of 4 wheel drive when it hits 55. I'm serious. I use 4 wheel drive every day to avoid damaging our 500' 16% grade gravel driveway. This morning, I drove 45 miles to work in 4 wheel drive. I didn't notice it until I turned into the driveway at work and felt the steering. It's easy to do. My wife's done it twice in our Sierra, twice in our last Yukon and now this one. I don't know how hard it is on it, but it can't be good. There's at least half of the trip over 70mph. Egads, what have I done to our new H3?
