: Service Stability System ??

11-10-09, 12:01 PM
Had two messages pop up on the dash yesterday, that I have not seen before. Did a search here on the board with no results.

"Service Stability system" is message 1, followed by "Service Brake assist" as message 2. This is accompanied with two lights that
won't go out. The ABS yellow light, and the Traction Control yellow light. On a side note, I had a slow leak fixed recently that required
the tire be dismounted from the wheel and re-installed. I know on the CTS-V, if the air inflation sensor went bad, it would not let you go into competition mode. This is obviously different and I am not sure what prompted this.

Any thoughts before I just take it to the dealer ??

Sounds like they may have knocked/damaged the wire going to the speed sensor in the hub. I'd say try there first seeing as your wheel was the last thing touched.

Just had my front hub replaced at the dealer because of a open on the sensor switch.

steering position sensor? That happened a few times on my CTSv and caused the same issue.

I just had my rear hub replaced for the sensor switch also.
