ON JULY 23 2008, I WAS BACKING OUT OF A PARKING SPOT AND I LOST ALL STEERING, THE PITMAN ARM SHEARED OFF. I HAD INSTALLED THE FAB-TECH PITMAN ARM, IDLER ARM, TIE ROD ENDS, AND STEERING STABILIZER KIT. I FOUND OUT LATER THAT THE PITMAN ARM, AND IDLER ARM, HAD A RECALL. I CONTACTED FABTECH VIA EMAIL AND THEY TOLD ME WHO TO CONTACT ABOUT THE RECALL. I LATER GOT TRANSFERRED TO ANOTHER GUY AT FABTECH. HE SENT ME INSTRUCTIONS ON HOW TO GO ABOUT THE RECALL TO GET REFUNDED THE ORIGINAL PURCHASE PRICE AND GET A CHECK FOR THE INSTALLATION AND FRONT END ALIGNMENT AND THEY ARE ALSO SUPPOSE TO SEND THE NEW IDLER ARM AND PITMAN ARM. FABTECH ASKED THAT I BOX AND SHIP THE OLD PARTS TO THEM AND THEY WOULD THEN INSPECT THEM AND SEND THE CHECK AND PARTS. I SENT THE PARTS IN AND THEN THEY DECIDED THEY WERE NOT GOING TO HONOR THE RECALL. I HAD COMPLETE STEERING FAILURE, LUCKILY I WAS IN A PARKING LOT WHEN IT HAPPENED. JUST HOURS BEFORE I WAS ON THE HIGHWAY. A RECALL IS A RECALL AND THEY NEED TO HONOR IT FOR ME AS WELL. *TR

ON RESTARTING THE VEHICLE MOMENTS AFTER HAVING DRIVEN IT WITHOUT ISSUE, THE BRAKE PEDAL FELT SPONGY, AND WITH MORE PRESSURE, SUNK TO THE FLOOR. FLUID WAS FOUND TO BE RUNNING OFF OF THE TRUCK FRAME UNDER THE DRIVERS DOOR. NO WARNING LIGHT CAME ON AT THE TIME. LATER, APPARENTLY WHEN THE FLUID HAD DRAINED DOWN ENOUGH, THE BRAKE WARNING LIGHT CAME ON. ON INSPECTION, ALL OF THE BRAKE LINES WERE FOUND TO BE VERY BADLY DECAYED JUST FORWARD OF THE ABS UNIT, WITH ONE HAVING FAILED. THIS IS NOT AN OFF-ROAD TRUCK. IT HAS HAD CONSERVATIVE ROAD USE. FORTUNATELY, I WAS NOT TOWING MY 8000 POUND TRAILER AT THE TIME. I RECENTLY SOLD A 1972 CHEVROLET WHICH HAD NEVER REQUIRED ANY BRAKE LINE REPLACEMENTS. WHY ARE THESE RELATIVELY NEW TRUCKS BRAKES ALL FAILING? *TR

I HAD JUST GOTTEN MY FUEL PUMP REPLACED AT A LOCAL GARAGE, WAS DRIVING IT HOME AND FOUND THE BRAKE PEDAL GOING ALMOST ALL THE WAY TO THE FLOORBOARDS. I PULLED OVER AT THE FIRST SAFE PLACE, FOUND A FLUID JUST GUSHING OUT AROUND GAS TANK AREA ON THE DRIVERS SIDE. IT HAD JUST RAINED FOR THE LAST FEW DAYS, SO I THOUGHT IT WAS JUST WATER. I DROVE A LITTLE FURTHER, THEN DECIDED TO DRIVE IT BACK TO THE GARAGE, ONLY ABOUT A MILE AWAY, AFTER SMELLING BRAKE FLUID AND VERIFYING THE MY RESERVOIR WAS SERIOUSLY LOW. MORE DRIPPING ON THE DRIVERS SIDE, THIS TIME I'M SICK TO CONFIRM IT IS BRAKE FLUID. TOOK IT BACK TO THE GARAGE, HE SAID HE'D LOOK AT IT TOMORROW, BUT I SAID I'D DRIVE IT HOME ALL OF 2 MILES DOWN THE STREET. GOT HOME NO ISSUES, CAUSE I USED THE E-BRAKE, AND FOUND THE RESERVOIR NEARLY DRAINED. NOTHING AROUND THE WHEELS; THIS WAS THE ONLY LEAK. NOW I'M THINKING THE BRAKE LINES MUST HAVE BEEN SERIOUSLY RUSTED (AGAIN!) AND GOTTEN DISTURBED WHEN THEY REPLACED THE FUEL PUMP. I HAD THIS HAPPEN SHORTLY AFTER I BOUGHT THE VEHICLE USED, ABOUT FIVE YEARS AGO. I PAID GOOD MONEY BACK THEN TO HAVE THE 'STAINLESS STEEL' BRAKE LINES TO THE ABS HEAD REPLACED BACK THEN. WHY ARE THEY RUSTED THROUGH AGAIN!?!?! HAD NO IDEA THEY RAN UP BY THE TOP OF THE TANK, BUT HEY, WHY NOT? I'M CERTAIN THE LINE HAVE RUSTED OUT AGAIN - WHY?!?!? THEY ARE SUPPOSED TO BE STAINLESS STEEL; SINCE WHEN DOES STAINLESS EVER RUST? I HAUL A 12,000LB FIFTH WHEEL; THANK GOD I WASN'T HAULING AT THE TIME THIS HAPPENED (AGAIN!) AND KILLED MYSELF AND MY ENTIRE FAMILY IN AN AUTO CRASH. JUST SICK OF IT; TAKE CARE OF YOUR BAD ENGINEERING CHEVY! *TR

REPEAT OCCURRENCE ON 6/22/2013. FIRST OCCURRENCE WAS IN APPROXIMATELY AUGUST OF 2010. BRAKE LINES SEVERELY RUSTED. HAVE KEPT UNDER WATCH, HOWEVER THE RATE OF RUST SEEMS TO INCREASE. WITH THIS LAST INCIDENT, ALL BRAKE LINES WILL HAVE TO BE REPLACED, COSTING WELL OVER $1000. VERIFIED WITH 3 LOCALS GARAGES THAT THIS IS A WELL DOCUMENTED PROBLEM FOR THIS YEAR AND AROUND THIS YEAR OF CHEVROLET TRUCKS. THEY HAVE ALL HAD TO DO REPAIR DUE TO VERY POOR QUALITY MATERIALS USED FOR THE BRAKE LINES. THIS TRUCK IS PRIMARILY USED TO PULL A HORSE TRAILER. I FEEL WE WERE FORTUNATE THAT THE ISSUE DID NOT OCCUR WHILE TOWING. GM SHOULD FEEL VERY LUCK. IF THERE WOULD HAVE BEEN AN ACCIDENT WHILE TOWING THE HORSE TRAILER, GM WOULD HAVE HAD A MAJOR LAWSUIT ON THEIR HANDS. AS IT IS, TIME FOR THEM TO DO THE RIGHT THING AND INITIATE THE RECALL. *TR
