What Owners Say
""Two problems very common on GMC message boards with little resolution by repair shops. 1. Shift to park. Shifter is in Park, dash display says to shift to park.My hack is to snap the button on shifter. 2. Driver Assist Reduced message. Occurs intermittently. Began around 55Kmi. Thermostat reads cold, sometimes idle races. Happens periodically after gas fills. Might be associated with ECT sensor oer my own research. Owners on GMC blog report expensive repairs but error recurs. Mine spontaneously appears then resolves. Goes through phases.""
