SERVICE BRAKES, HYDRAULIC
BRAKE LINE RUPTURE, 2003 GMC SIERRA 2500HD PICKUP. TOTAL LOSS OF BRAKING WHILE STOPPING FOR TRAFFIC AT 60 MPH. ALL LINES WERE ROTTED AND HAD TO REPLACED. CRASH WAS AVOIDED BECAUSE OTHER CARS REALIZED I HAD LOST BRAKING AND MOVED OUT THE WAY. DID NOT REPORT UNTIL NOW(DEC 2010) BECAUSE I THOUGHT IT WAS AN ISOLATED INCIDENT. NOW FINDING OUT THAT IT IS PREVALENT, SO MUCH, THAT I HAVE WARNED FRIENDS ABOUT IT AND AM FINDING IT TO BE QUITE COMMON. *TR

SERVICE BRAKES, HYDRAULIC
WAS COMING TO A STOP SIGN AND HAD TOTAL BRAKE FAILURE. LUCKILY I WAS THE ONLY ONE ON THE ROAD AND ABLE TO KEEP CONTROL OF THE VEHICLE AND LIMP IT BACK HOME. COULD HAVE BEEN MUCH WORSE. FOUND RUSTED BRAKES LINES UNDER THE TRUCK JUST SPRAYING FLUID WHEN THE BRAKES ARE APPLIED. NEEDS ALL NEW BRAKE LINES FROM FRONT TO BACK. HAVE FOUND MANY COMPLAINTS ABOUT THIS ONLINE. GM SHOULD RECALL THESE VEHICLES AS THEY ARE NOT SAFE! *TR

SERVICE BRAKES, HYDRAULIC
PROBLEM IS INTERMITTENT. BRAKE AND ABS WARNING LIGHTS COME ON AND STAY ON UNTIL ENGINE IS TURNED OFF. NO DETECTABLE CHANGE IN BRAKING. SEPARATELY, BUT ALSO INTERMITTENTLY, AT LOW SPEEDS (NO WARNING LIGHTS) THE ABS IS ENGAGED WHILE BRAKING, MAKING THE VEHICLE HARD TO STOP AT TIMES. THIS SEEMS TO OCCUR MOST FREQUENTLY WHEN TURNING TO THE LEFT. SYMPTOMS ARE VERY SIMILAR, IF NOT IDENTICAL TO NHTSA CAMPAIGN ID NUMBER : 05V379000. MANY ANECDOTAL DESCRIPTIONS OF THIS SAME PROBLEM IN 1999-2002 GMC LIGHT TRUCKS CAN BE EASILY FOUND ON THE INTERNET.

SERVICE BRAKES, HYDRAULIC
2006 SIERRA DENALI WITH JUST OVER 75,000 MILES. WITH 1/2 BLOCK WARNING AND ONLY TRAVELING AT A SPEED OF 20MPH, I WAS UNABLE TO COME TO A COMPLETE STOP. THE BRAKE PEDAL WAS ALL OF THE WAY TO THE FLOOR WHEN I RAN INTO A VAN IN THE INTERSECTION. I FELT VERY LITTLE RESISTANCE FROM THE PEDAL AND THE ABS DEFINITELY DID NOT GO OFF. THERE WAS NO SNOW OR ICE ON THE ROAD SURFACE. HOWEVER AFTER TOWING THE VEHICLE TO THE LOCAL DEALERSHIP, I WAS TOLD NOTHING WAS WRONG WITH THE TRUCK. TWO INDEPENDENT THIRD PARTIES HAVE SUGGESTED THIS COULD BE A MASTER CYLINDER ISSUE EVEN THOUGH GMC GAVE IT A CLEAN BILL OF HEALTH. *TR

POWER TRAIN:DRIVELINE, TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS
MY 2008 GMC SIERRA 3500HD HAS A CHATTER WHEN TURNING, GM IS AWARE OF THE PROBLEM AND HAS A BULLETIN FOR A REPAIR, HOWEVER THE REPAIR MAY OR MAY NOT COMPLETELY SOLVE THE ISSUE IT DIDN'T ON MINE. WHILE TURNING THE REAR AXLES STAYS IN A LOCK POSITION AND DOESN'T ALLOW THE REAR TIRES TO TURN SEPARATE SPEEDS THIS CAN CAUSE THE VEHICLE TO GO INTO A SKID WITHOUT NOTICE AND THEY SET FRONT AND REAR TIRE PRESSURES DIFFERENT AND THE DOOR STICKERS CONFIRM THAT THIS IS LIKE DRIVING A 4 WHEEL DRIVE WITH SMALL TIRES ON THE FRONT AND BIG TIRES ON THE BACK. NOT ONLY DOES THIS CAUSE DRIVELINE FAILURES BUT ALSO COULD BECOME UNSAFE AND CAUSE A LOSS OF CONTROL. I HAVE SPUN OUT MORE THAN ONCE WHILE TURNING AT LOW SPEEDS AND ONCE WAS ON THE WAY HOME FROM THE DEALER AFTER THE SERVICE MANAGER TOLD ME IT WAS FIXED HE "DROVE IT HIMSELF" IT HAS RUINED THE TIRES AND NOW THEY ARE REBUILDING THE REAR AXLE WITH ONLY 25000 MILES ON IT. *TR
