We got several warning messages concerning traction control, stabilitrac, and brake system. the authorized dealer found that brake fluid was leaking from the master cylinder into the brake booster, requiring replacement of both components. online searches reveals this is common problem within the buick line and other gm products. our experience with this failure was uneventful but could have a tragic ending if one was to continue driving an affected vehicle with low or lacking brake fluid.
