Had a bit of a scare. Was driving down the interstate when "Service Stabilitrak" came up. Fine. Less than a minute later, all gauges shut off, including the DIC, and then the DIC came back on and started displaying "Service 4WD", "Service Brakes", "Brake assist off, drive with care", "Steering assist off, drive with care". Then something among the lines of "Power Steering Malfunction" came on at which point the only thing that worked was the engine and the radio. I've driven cars without power steering before, including older trucks, but this was beyond anything I've ever had to steer. Oh, and after exiting the highway I stopped at a red light and had another surprise: transmission wouldn't shift out of first anymore. It's amazing how dependent on electrics modern vehicles are.
Looking forward to have the dealer tell me what happened.
