On-Star's diagnostic of my 06 STS seems unable to read the tire pressures to include in their monthly email report. The report under maintenance states: "Your tire pressure information is temporarily unavailable. Please try again later." Thats been on all reports I've gotten so far. Don't know how long temporary is. On-star technical doesn't seem to have an answer to what the problem is and hasn't offered any help. Guess they think I don't have it. However, it's there and I can read the tire pressures on the DIC. Anybody out there had any problems with the TPMS readings or got any ideas or recommendations? Not that the TP reading is that important, but since I have it, I would like to see it in the report.
