Whatever caused the warning is probably stored as a history code. Try pulling the codes and see if anything stability related comes up.
Had the same problem on my '03 DHS. The dealer fiddled with it, said it was a steering wheel sensor issue, and it went away.
This is a chevy dealer, not Cad, The closest Cad dealers is 65 miles so they get to do warranty work there. They ordered a new sensor, it came in and is being put on tomorrow moring. Will the new sonsor be calibrated correctly or will this just happen again? They called the Cad TSL and were told to replace it.
