I have the Elec Stabil as well Brake Bass Assist lights on. I also feel my power steering is not working properly. All these problems started soon after I fixed my Airmatic shocks. I am not sure what the connection is. The car had been driving very well for 6 yrs.
Brake fluid flush, about $85 at my local repair place.
