Don't know if it is all related, but.....
My December OnStar diagnostic email said my tire pressures were low. The in-car reading was mixed. I checked with a gadge and they were all spot on.
I took the vehicle in for an oil change, tire rotation and 15K service ($220 worth of service) on Friday (New Years Eve). The next day I went for a short drive and a warning screen popped up saying there was no pressure (or no reading from) the left rear tire. I stopped (thinking I somehow had a flat), but the tire looked fine (just like the other three).
I figured that during the service visit tire rotation, something had not been connected correctly or had come loose. I took the Terrain back to the dealer service this morning. They said that the sensor was defective and replaced it (no charge - warrenty).
Anyway, this is the first problem I have experienced with my 15,050 miles 2010 Terrain.
