Shortly after purchasing my 2019 GMC Acadia with approximately 52,000 miles, the vehicle displayed a "Steering Assist is Reduced. Drive with Care." warning message and illuminated the check engine light with diagnostic code P0128 00 (Engine Coolant Temperature Below Thermostat Regulating Temperature). I disconnected and reconnected the battery, after which both the warning message and check engine light disappeared. However, the engine coolant temperature gauge then began behaving erratically. On multiple cold starts, the gauge would immediately indicate that the engine was already at normal operating temperature even though the engine had been sitting long enough to be completely cold. This led to a diagnosis of a thermostat and/or engine coolant temperature sensor failure.

Shortly after purchasing my 2019 GMC Acadia with 52,000 miles on it, my wife parked the vehicle in our driveway and shifted the transmission into Park. When she pressed the push button to shut the vehicle off, the instrument cluster displayed a "Shift to Park" message even though the shifter was already in the Park position. Because the vehicle did not recognize that it was in Park, it would not shut off completely. The radio remained on, and the doors could not be locked. The only way to get the vehicle to shut off was to repeatedly shift from Drive to Park until it finally recognized Park. This occurred multiple times. After researching the problem, I discovered that many other GM owners have experienced the same "Shift to Park" failure. I believe this is a widespread defect that should be investigated because it can prevent a vehicle from shutting off properly, leave electrical accessories powered on, drain the battery, and prevent the vehicle from being secured when parked.
