THERE IS NO WARNING THE PEDAL GOES TO THE FLOOR AND YOU DON'T STOP. I HAD A 5TH WHEEL TRAILER HOOKED TO MY 2006 GMC 2500 EXT. CAB LONG BED SIERRA P/U WITH 62,459 MILES ON IT. I WAS ABLE TO STOP IT WITH THE TRAILER BRAKES AND A SCRATCH ON MY FRONT BUMPER FROM A TRACTOR TRAILER THAT WAS IN FRONT OF ME. I HAVE OWNED OVER 200 CARS + TRUCKS SINCE I STARTED DRIVING. I DO ALL MY ONE WORK ON THEM AND I NEVER HAD A BRAKE LINE FAIL, I WILL BE 70 THIS YEAR. IT IS RIDICULOUS FOR AN 8 YEAR OLD TRUCK TO HAVE RUSTED BRAKE LINES TO FAIL. THE WORST PART OF THIS IS THAT NOBODY NOTIFIED THE PUBLIC THAT THIS WAS A PROBLEM WHEN THEY GMC KNOWS ABOUT THIS PROBLEM. I FOUND A GARAGE THAT FIXED THE TWO FRONT LINES. SO WE COULD GET HOME. THEN I INSPECTED THE OTHER LINES AND ORDERED THE COMPLETE SET OF STAINLESS STEEL LINES FROM EBAY, WHEN I REMOVED THE OLD LINES THEY ALL WERE RUSTED AT HIDDEN SPOTS TWO WERE CLOSE TO FAILING. WHY DO THEY HAVE TO WAIT FOR SOME ONE TO DIE BEFORE THEY NOTIFY THE PUBLIC THERE IS A SAFETY PROBLEM. THIS IS GMC AND OUR GOVERNMENT (NHTSA) FAILING THE PEOPLE. *TR

I HAVE A 2006 GMC SIERRA WITH THE SAME ABS ISSUES THAT ARE RECALLED FOR OLDER VEHICLES. ABS ENGAGES AT LOW SPEEDS WHEN COMING TO A STOP INCREASING STOPPING DISTANCES. I TOOK IT TO DEALER AND THEY REPLACED THE REAR BRAKES. TRUCK HAS ONLY 41000 MILES ON IT, I WOULDN'T THINK THE REAR DRUM BRAKES WOULD BE WORN OUT. I DROVE IT HOME LAST NIGHT AND TO WORK TODAY. SAME PROBLEM STILL EXISTS. WILL RECALL BE EXTENDED TO INCLUDE MY VEHICLE SOMEDAY? *TR
WHEN I WENT TO START THE TRUCK IN THE MORNING, I PUT MY FOOT ON THE BRAKE PEDAL AND IT WENT TO THE FLOOR. GOT OUT AND SAW THE BRAKE FLUID ON MY DRIVEWAY. EXAMINED THE TRUCK AND FOUND A STEEL BRAKE LINE HAD RUSTED THROUGH AND OTHERS HAD SIGNIFICANT RUST. *TR
TRUCK HAS HAD AN UNDERCARRIAGE RUST ISSUE AT LEAST SINCE 2007. THE FUEL AND BRAKE LINES MUST BE REPLACED AND THE FRAME AND SUSPENSION ARE DETERIORATING. *TR
WHEN SLOWING TO COMPLETE STOP, THE ABS MOTOR ENGAGES UNDER 10 MPH ON DRY PAVEMENT. THIS CAUSES THE TRUCK TO TAKE A FEW MORE FEET TO STOP. ABS LIGHT COMES ON WHILE MOVING AT TIMES. *TR
ABS MOTOR ENGAGES ON DRY PAVEMENT AT LOW SPEEDS WHEN COMING TO A STOP, ABOUT 10 MPH OR LESS. *TR
ANTILOCK BRAKING SYSTEM (ABS) ACTIVATES CONSISTENTLY AS VEHICLE NEARS FULL STOP. IT'S AUDIBLE AND YOU FEEL THE PULSATION IN THE BRAKES. THE ROAD CONDITIONS ARE NORMAL AND THERE IS NO REASON FOR THE ABS TO ACTIVATE. *TR

CERTAIN SPORT UTILITY VEHICLES AND TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 110, "TIRE SELECTION AND RIMS." THESE VEHICLES HAVE AN INCOMPLETE TIRE RIM DESIGNATION ON THE CERTIFICATION/TIRE LABEL LOCATED ON THE DRIVER'S DOOR EDGE. IN ADDITION, THE LABEL MAY ALSO BE MISSING THE TIRE LOAD RATING ON THE LABEL. ALTHOUGH THIS INFORMATION IS NOT REQUIRED BY THE STANDARD, IF A TIRE OF A LESSER LOAD RATING IS INSTALLED, THE TIRE MAY NOT BE ABLE TO SUSTAIN THE LOADS ENCOUNTERED DURING USE.
Consequence & remedy
Consequence: IF A CUSTOMER REPLACES A WHEEL AND ONLY RELIES ON THE RIM SIZE DESIGNATION THAT IS INDICATED ON THE LABEL, A WHEEL THAT IS OF A DIFFERENT RIM CONTOUR DESIGNATION MAY BE INSTALLED. IT MAY BE DIFFICULT OR IMPOSSIBLE TO MOUNT THE TIRE ON A WHEEL WITH THE WRONG CONTOUR. IF THE TIRE IS MOUNTED ON THE WHEEL WITH THE WRONG CONTOUR, THE WHEEL AND TIRE MAY NOT PERFORM AS INTENDED, WHICH COULD INCREASE THE RISK OF A CRASH.
Remedy: A LABEL THAT WILL CORRECT THE LABEL ORIGINALLY INSTALLED WILL BE MAILED TO CONSUMERS ALONG WITH INSTALLATION INSTRUCTIONS. THE CUSTOMER WILL HAVE THE OPTION FOR DEALERS TO INSTALL THE LABEL.
