2013 XTS.... during drive the tire pressure sensors seem to disconnect to the car and then an error is shown. Later they reappear. Is more than one tire and comes and goes. Sometimes it is one tire, sometimes two.
Here is something that my local dealer told me that isn't directly related to this thread. When buying a new car from them, they insist on filling the tires with nitrogen (at no charge) because they have found through experience over the years that nitrogen-filled tires result in far fewer tire pressure sensor failures than tires that are filled with regular air. Does anyone have any solid evidence on this either way?
