Consumer Description

WHEN RESTARTING AFTER VEHICLE "AUTO STOP" I AM GETTING "SERVICE BRAKE ASSIST" AND OCCASIONALLY "SERVICE ESC" WARNINGS. THESE WARNINGS WERE ASSOCIATED WITH BRAKE FAILURE IN GM SUV'S AND PICKUPS AND WERE SUBJECT TO A RECALL. NO SUCH RECALL EXISTS FOR THE TERRAIN. I HAVEN'T YET EXPERIENCED A BRAKE FAILURE BUT GM SEEMS TO WANT TO WAIT UNTIL I DO TO FIX THE PROBLEM.
