I recently bought my first caddy,a '01 DHS from a friend. It has just over 62,000. mi. (about 3,500 mine). The SERVICE STABILITY SYS prompt has come on several times. Initially, I thought it was due to improper tire pressures, but it still comes on ocasionally. It seems to handle OK...but it does wallow compared to my old Toyota Highlander. When I clear the prompt, it does not come back on right away,maybe every week or so (once when I made a jerky motion in a parking lot to avoid a mishap.)Has anyone had a similar situation? What is the indicated solution, cost and can it be fixed by an independent shop? I welcome your comments.

Iam not 100% on this but here goes, I have 01 STS and I believe I had the same message, took it to dealer and they found a wire harness under the drivers seat had came unpluged. Hope this is your problem, would be cheap way uot.
