WHILE TOWING A 7000 LB 5TH WHEEL TRAILER THE ELECTRICAL PLUG BETWEEN THE VEHICLE AND TRAILER BECAME PARTIALLY DISLODGED AND AFFECTED THE VEHICLE ELECTRICAL SYSTEM WHICH MADE THE GAUGE NEEDLES GO HAYWIRE INCLUDING THE TACHOMETER. ENGINE STALLED WITH RESULTANT LOSS OF POWER STEERING AND BRAKES. LUCKILY WAS ABLE TO PULL INTO PARKING LOT AND STOP USING TRAILER BRAKES. REINSERTED PLUG FULLY INTO SOCKET AND HAVE NOT HAD A PROBLEM SINCE. *TR

WAS BACKING OUT OF THE DRIVEWAY AND WHEN I TRIED TO STOP THE BRAKE PEDAL WENT ALL THE WAY DOWN AND I HAD NO BRAKES. THERE WAS NO WARNING WHATSOEVER THAT I HAD A BRAKING PROBLEM. WHEN I LOOKED UNDERNEATH THE TRUCK I COULD SEE THAT THE BRAKE LINES ARE VERY CORRODED AND ONE IS LEAKING. IT LOOKS LIKE THEY WILL ALL NEED TO BE REPLACED AND THE TRUCK WILL PROBABLY NEED TO BE TOWED IN TO HAVE THIS DONE. IT SOUNDS LIKE THIS WILL BE A VERY COSTLY FIX. I BOUGHT THIS TRUCK NEW AND IT HAS ALWAYS BEEN GARAGED AND WELL TAKEN CARE OF. *TR

ON TRIP HOME FROM A VACATION. PULLING A 28 FT FIFTH WHEEL CAMPER AND A MOTORCYCLE TRAILER. ON INTERSTATE 65 NORTH BOUND WHEN AN OLDER GENTLEMAN MERGING INTO TRAFFIC THOUGHT IT WAS A GOOD IDEA TO COME TO ALMOST A COMPLETE STOP TO LET OTHER VEHICLE MERGE IN FRONT OF HIM. AT WHICH POINT I HAD TO LOCK THE BRAKES AND JUST AFTER THE ABS STARTED TO COME INTO EFFECT THE BRAKE PEDAL WENT TO THE FLOOR. LUCKILY JUST BEFORE I WAS GOING TO IMPACT THE VEHICLE IN FRONT OF ME HE PULLED AWAY. I TOOK THE NEXT EXIT OFF THE INTERSTATE PULLED TO THE SIDE OF THE EXIT RAMP TO DISCOVER BRAKE FLUID DRIPPING ON THE GROUND JUST FORWARD OF THE DRIVERS DOOR. INSPECTED THE BRAKE FLUID LEVEL TO DISCOVER IT WAS EMPTY. ALL BRAKE LINES ON THIS VEHICLE WILL HAVE TO REPLACED AT AN ESTIMATED COST FROM A DEALER AT $1500.00. THIS IS A SAFETY ISSUE AND SHOULD BE IN A RECALL STATUS. *TR

SAME STORY AS EVERY OTHER 99+ SILVERADO: THE BRAKE LINE BURST BEHIND CAB AND ALL BRAKE PRESSURE WAS LOST. BRAKE SYSTEM DEFECTS ARE FAR MORE DANGEROUS THAN A FAULTY IGNITION SWITCH. WHY ARE GM AND NHTSA IGNORING THESE COMPLAINTS? *TR

WHILE DRIVING ON CITY STREETS , I WENT TO STOP BEHIND A CAR AT A STOP LIGHT AND THE BRAKES WENT TO THE FLOOR WITH NO WARNING. I HIT THE CAR FROM BEHIND AND LUCKILY NO ONE WAR INJURED BUT MINOR DAMAGE TO THE REAR OF THE CAR WAS OBSERVED. AFTER THE INCIDENT, OIL CONTINUED TO LEAK FROM THE LINE UNDER DRIVER SIDE DOOR, THE WARNING LIGHT DID COME ON BUT AFTER THE ACCIDENT HAD ALREADY OCCURRED. THIS WAS THE FIRST FAILURE. BRAKE LINE WAS REPAIRED AND A YEAR LATER, THE SECOND BRAKE LINE FAILED ON MAY 23, 2014. WHILE PULLING BOAT OUT OF BOAT RAMP, I WENT TO STOP THE TRUCK AND THE BRAKE PEDAL WENT TO THE FLOOR AGAIN , LUCKILY NOT GOING FAST OR DOWN AN INTERSTATE. AGAIN THE LEAK WAS FROM UNDER THE DRIVER SIDE DOOR, BUT WAS THE OTHER PARALLEL LINE GOING TO THE ABS BLOCK. THIS IS A SERIOUS SAFETY ISSUE AND I WAS VERY LUCKY TWICE. ALL BRAKE LINES WILL BE REPLACED WITH STAINLESS STEEL LINES. I WILL NOT BUY ANOTHER GM PRODUCT UNLESS THEY MAKE THIS RIGHT. *TR

ON MAY 9, 2014 I WAS BACKING UP TO HOOK UP TO A TRAILER WITH MY TRUCK. WITH ABSOLUTELY NO WARNING SIGN OR INDICATION, MY BRAKE LINE BUSTED AND I HAD NO BRAKES WHATSOEVER. THE PEDAL WENT ALL THE WAY TO THE FLOOR. EVEN AT THIS SLOW OF SPEED IN REVERSE I COULD NOT STOP AND RAN DIRECTLY INTO THE TRAILER. MY WIFE WAS STANDING AT THE TRAILER DIRECTING ME AND LUCKILY DID NOT GET HURT BECAUSE OF THIS BRAKE FAILURE. I HAD TO USE THE EMERGENCY BRAKE TO GET STOPPED, AND EVEN THAT WAS VERY SLUGGISH TO STOP THE TRUCK. I AM NOW FINDING OUT THAT THIS IS COMMON ISSUE WITH THESE VEHICLE AND THERE IS AN OPEN INVESTIGATION INTO THIS MATTER. GM NEEDS TO DO SOMETHING ABOUT THIS AS THE IMMEDIATE FAILURE OF THE BRAKES WITH NO WARNING IS SURE TO CAUSE SERIOUS INJURY OR DEATH SHOULD IT HAPPEN WHILE DRIVING DOWN THE ROAD. *JS

MY WIFE USED MY 2500 HD 4WD PICKUP TO GO TO WORK DURING INCLEMENT WEATHER. SHE CALLED ME WHILE DRIVING AND THOUGHT THE ROAD WAS ICY BECAUSE SHE THOUGHT SHE SLID THROUGH TWO BUSY INTERSECTIONS. I ASKED HER HOW FAST SHE WAS DRIVING AND SHE SAID NOT REAL FAST BUT THE TRUCK DID NOT STOP. I TOLD HER TO TAKE IT EASY AND APPROACH INTERSECTIONS SLOWLY. SHE MADE IT TO WORK AND HOME LATER THAT NIGHT (2ND SHIFT) SAFELY. THE NEXT MORNING I DROVE THE TRUCK TO WORK AND PROMPTLY DROVE RIGHT THROUGH A BUSY INTERSECTION NEAR HOME WITH THE BRAKE PEDAL ON THE FLOOR. WIFE DID NOT NOTICE PEDAL SINCE SHE IS ONLY 5'1" AND DIDN'T HAVE PEDAL TO FLOOR. LUCKILY THERE WAS NO TRAFFIC EARLY IN THE MORNING OR RESULTS COULD HAVE BEEN CATASTROPHIC. GOT TRUCK HOME AND DID A THOROUGH CHECK OF BRAKE SYSTEM. LINE FROM FRONT OF MASTER CYLINDER TO ABS MODULE ON FRAME RAIL WAS RUSTED THROUGH. OTHER LINES ALSO LOOKED LIKE THEY WERE DUG UP FROM DAVEY JONES LOCKER AT THE BOTTOM OF THE OCEAN. I'VE OWNED THIS TRUCK FROM NEW AND HAVE TAKEN GREAT CARE OF IT. MY 1968 CHEVELLE HAS BETTER LOOKING ORIGINAL BRAKE LINE ON IT. DON'T KNOW WHAT IS GOING ON BUT THIS IS A SERIOUS PROBLEM, AND NOT JUST BRAKE LINES FROM WHAT I HAVE READ. GM NEEDS TO ADDRESS THIS THROUGH A RECALL BEFORE SOMEONE GETS KILLED, IF IT DIDN'T HAPPEN ALREADY. I DID CALL DEALER I BOUGHT TRUCK FROM AND THEY ACKNOWLEDGED KNOWING THERE IS A PROBLEM, BUT OFFERED NO ASSISTANCE OTHER THAN FREE QUOTE TO REPAIR (WITH OEM STEEL LINES). I BOUGHT AN AFTERMARKET SET OF SS LINES FOR THE ENTIRE TRUCK AND HAVE INSTALLED BOTH MASTER CYLINDER LINES SO FAR. WAITING FOR WARM WEATHER FOR THE REST....HOPE ANOTHER DOESN'T FAIL IN THE MEANTIME ! *TR
