One problem related to automatic stability control (asc) has been reported for the 1998 Cadillac Concours. The most recently reported issues are listed below.
Driving and the stability light came on and the car began to bounce slightly. Continued to drive and bouncing had gotten worse and eventually cased me to go off the road when switching lanes the back end of my car spun around. Thank god their were no other cars around or it would have been a horrible accident.
