As a long time GM owner I've never had early failures on my vehicles and I tend to keep them for a long time. I'm currently driving a 2011 gmc sierra z60 with 216k and the drive train has never failed. My wife's 2014 Buick enclave has 179k and still drives and looks like a new car. Not a gm product but I had a 1986 jeep Wagoneer ( last of the old AMC models) that I sold with 286k on it. Wish I still had it.
