AKA Gomez Addams
Terry: It may interest you to know, that even when you are not subscribed to OnStar, the service monitors you use of the vehicle. When the wife's 2008 Caddie was due for service, I arranged to take it to the Caddie dealer. While driving over, on the morning of the appointment, I noticed the green on star light was on, although I have not subscribed to the service for over a year. When my turn with the Service advisor came up, he had all the recent diagnostic data, including tire pressure on his screen...now, where do you suppose they gleaned that data? The day following the visit, the wife complained that her settings had changed. There was nothing, that the dealer did, to change anything, they just changed the oil, and rotated the tires.
