Here's another ongoing problem with this vehicle which happens everyday with two times in the shop and the dealer is unable to fix it:
Engine temperature gauge goes up all the way to high temp and "Engine Coolant Over Temperature" warning appears on the screen - most of the time the warning does not lock in however there have been times when it did lock in and I had to "acknowledge" it. For whatever reason the dealer has not replaced any parts such as the thermostat or sensor which brings me to a question: is the coolant high temp detected through an ECT sensor or through a cylinder head temperature sensor or something else ?
