Summary: CERTAIN SPORT UTILITY VEHICLES WERE BUILT WITH A LEFT-FRONT BRAKE PIPE WITH A CIRCUMFERENTIAL SCORE AT A RANDOM LOCATION ALONG THE LENGTH OF THE PIPE AS THE RESULT OF THE MANUFACTURING PROCESS. IF THE BRAKE PIPE AT THE SCORING LOCATION CORRODED TO THE POINT THAT THE BRAKE PIPE WALL BECAME VERY THIN, AND APPLICATION OF THE BRAKE DEVELOPED ENOUGH PRESSURE TO PARTIALLY OR FULLY FRACTURE THE BRAKE PIPE, BRAKE PEDAL TRAVEL WOULD IMMEDIATELY INCREASE AND FRONT BRAKE PERFORMANCE WOULD BE REDUCED. OR, IF THE BRAKE PIPE WALL AT THE SCORING LOCATION PARTIALLY OR FULLY FRACTURED DUE TO A COMBINATION OF PRESSURE, VIBRATION, OR TEMPERATURE INDUCED FATIGUE, THE BRAKE PEDAL TRAVEL WOULD IMMEDIATELY INCREASE AND FRONT BRAKE PERFORMANCE WOULD BE REDUCED. IN THESE INSTANCES, BRAKING WOULD BE LIMITED TO THAT AVAILABLE WITH THE REMAINING HALF SYSTEM (REAR BRAKES).
Consequence: IF THIS OCCURS WHEN STOPPING DISTANCE IS LIMITED, A CRASH COULD OCCUR.
Remedy: DEALERS WILL REPLACE THE LEFT-FRONT BRAKE PIPE. GM HAS NOT YET PROVIDED AN OWNER NOTIFICATION SCHEDULE. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT GMC AT 1-800-462-8782.
Important Note Regarding Auto Recalls: Frequently this site will list auto recalls before your dealer will know about them. If you have a vehicle affected by one of these posted recalls be sure and write down the NHTSA CAMPAIGN ID Number. If your dealer doesn't know about the recall when you check, ask them how they are notified of recalls and when the next update is due.
