DUE TO SEVERAL PAST ABS INCIDENTS, ONE RESULTING IN A COLLISION, VEHICLE WAS TAKEN TO DEALER FOR COMPLIANCE WITH NHTSA CAMPAIGN ID NUMBER 01I006000. SUBSEQUENTLY, PANIC STOP MAXIMUM BRAKING IS DELAYED. THERE IS EXCESSIVE RESISTANCE TO INITIAL BRAKE PEDDLE MOVEMENT AS IF THERE IS NO BOOST. AFTER APPROXIMATELY 1/2 SECOND, WITH HEAVY PRESSURE APPLIED TO THE PEDDLE, ACTUAL WHEEL BRAKING CAN BE FELT TO PROGRESSIVELY INCREASE AND RESISTANCE TO PEDDLE MOVEMENT REDUCES. AT THIS POINT BRAKING FEELS ABOUT NORMAL. DEALER TECHNICIAN ON TEST DRIVE CONFIRMED THIS DESCRIPTION OF PROBLEM. HOWEVER, TECHNICIANS HAVE NOT BEEN ABLE TO IDENTIFY ANY MALFUNCTIONING COMPONENTS.*AK
MY SUBURBAN HAS HAD 4 RADIATOR FAILURES SINCE NEW. ALL HAVE BEEN DUE TO ELECTRALISIS. GMC PAID FOR THE 1ST FAILURE (PART ONLY I PAID LABOR) EVEN THOUGH THE TRUCK WAS OVER 10000 MILES OUT OF WARENTY. THE 4 RADIATOR HAS NOW FAILED AND A 5TH IS REQUIRED. GMC IS WELL AWARE OF THIS PROBLEM BUT INSISTS THIERS NOTHING WRONG WITH THE COOLING SYSTEM. AS A SIDE NOTE THE HEATER CORE HAS NEVER BEEN REPLACED. THANKS FOR YOUR TIME, AL GREENFIELD. *AK
