Today I had this same message (first time) on my 2008 with 3K miles. I read these posts the other day and then it happened to me. I had just started up and driven out of a market parking lot, 10 MPH up to 25 MPH. Aprox. 90 seconds after start up, the "Stabilitrack not ready" came on. I continued at 25 MPH and quickly switched the 'traction control' off and then back on. The message went off instantly. The engine/car were at running temps, the weather was sunny and windy at 78 F. I always let the gauges and lights 'settle' before shifting or moving the car, and never 'blast off' when engine is cold. My detail guy did work on the car the day before, aprox 4 hours. Could it be low battery? The battery was 12 months old on 03/13/09, so I replaced it on 03/12/09, 850 CCA. I'm not going to read any more of anyone's problems because I don't want a transference of KARMA. HA HA!
