BRAKE LINES ARE SEVERELY CORRODED. LUCKILY THERE WAS NO ACCIDENT. ALSO OWN AN 87 & 83 MERCEDES BENZ, NO ISSUES WITH CORROSION ON ANY FUEL OR BRAKE LINES. BRAKES ARE THE MOST IMPORTANT SYSTEM ON A VEHICLE. GM SHOULD BE MADE TO FIX THIS, THIS IS NEGLIGENT CORPORATE BEHAVIOR. *KB

SERVICE BRAKES, HYDRAULIC
BRAKES FAILED, VEHICLE BROUGHT TO A STOP USING 1ST GEAR AND PARKING BRAKE, NARROWLY AVOIDING ACCIDENT. PARKED IN PARKING LOT AND BRAKE FLUID DRAINED TO PAVEMENT. DEALER ADVISES REPLACEMENT OF ALL BRAKE LINES AS ALL ARE SEVERELY CORRODED (ESTIMATED COST - $2,400). VEHICLE IS EXACTLY 5 YEARS OLD WITH NOT MANY MILES. USED IN CANADA IN THE SUMMER AND FLORIDA IN WINTER MONTHS. ONLY EXPOSURE TO SALT AND SNOW IS WHEN ENCOUNTERED ON TRIPS TO AND FROM FLORIDA. VEHICLE WAS UNDERCOATED AT PURCHASE. VERY DANGEROUS FAILURE, MOST CERTAINLY MUST HAVE BEEN FATALITIES GIVEN THE NUMBER OF REPORTS AND COULD HAVE BEEN US YESTERDAY OR WHEN TOWING 5TH WHEEL RV. *KB

SERVICE BRAKES, HYDRAULIC
THE REAR BRAKE PADS SQUEALED & WERE GRINDING & THE TRUCK HAD VERY POOR STOPPING POWER. THE TRUCK WAS TAKEN TO MY MECHANIC & HE WAS DOING THE BRAKE JOB; HE REPLACED ALL FOUR ROTORS BECAUSE THEY WERE RUSTED BEYOND REPAIR. THE PADS WERE REPLACED AS WELL. WHILE HE WAS DOING THE BRAKES HE OBSERVED THE BRAKE LINES WERE RUSTED TO A POINT THAT IT ALARMED HIM & HE SAID THEY SHOULD BE CHANGED. HE ALSO COMMENTED THAT THE BRAKES HAD WORN VERY UNEVEN. THE FRONT PADS WERE BARELY WORN & WERE ONLY MAKING CONTACT AT A SMALL AREA OF THE ROTOR (ABOUT 1/2" OF THE FULL FACE ON THE ROTOR). THE BACK PADS & ROTORS WERE COMPLETELY WORN DOWN & THE ROTORS WERE RUINED. SOME OF THE AREAS UNDER THE TRUCK LOOK AS NEW & OTHER PLACES; MAINLY THE A-FRAMES, BRAKE LINES, SOME FRAME MEMBERS, ETC. LOOK LIKE THEY ARE 15 YEARS OR MORE OLDER. THE BRAKES WERE PUT BACK TOGETHER & NOW THEY ARE SO TIGHT & WON'T RELEASE THE ROTORS, CAUSING THE ROTORS TO OVER HEAT. I AM NOW HAVING HIM REPLACE THE BACK TWO CALIPERS WITH REPLACEMENT CALIPERS THAT USE PHENOLIC PISTONS RATHER THAN STEEL & ARE NOT GM PARTS. *KB

ENGINE AND ENGINE COOLING
I OWN A 2007 GMC SIERRA 1500 CREW CAB. I HAVE SOME ISSUES WHEN I START MY TRUCK IN THE MORNINGS, I GET A TAPPING NOISE AS IF THERE ARE LIFTERS STUCK OR NOT GETTING SUFFICIENT OIL. I HAVE ALWAYS USED THE RECOMMENDED AC OIL FILTERS THAT I PURCHASE FROM THE LOCAL DEALERSHIP PARTS CENTER SO I KNOW THAT THE FILTER IS NOT THE PROBLEM. I AM A MECHANIC SO I KNOW WHAT AN ENGINE IS SUPPOSED TO SOUND LIKE. THE NOISE WILL CONTINUE UNTIL THE ENGINE WARMS UP WHICH IS APPROXIMATELY 10-15 MINUTES AND IS VERY ANNOYING. I AM CURRENTLY DEPLOYED TO KANDAHAR, AFGHANISTAN IN SUPPORT OF OPERATION ENDURING FREEDOM AND SCHEDULE TO RETURN TO THE US IN LATE MARCH 2012. I SPOKE TO MY WIFE TODAY AND SHE SAID THAT EVERY TIME SHE START THE VEHICLE FOR THE FIRST TIME THE NOISE IS THERE. I WOULD APPRECIATE IF YOU COULD ANSWER MY QUESTION CONCERNING THIS ISSUE. I LIKE THE TRUCK BUT THE ENGINE NOISE HAS TO GO. LIKE I SAID BEFORE I HAVE BEEN A MECHANIC FOR OVER 30 YEARS ON CONSTRUCTION EQUIPMENT AND AUTOMOTIVE EQUIPMENT FOR THE US ARMY. PLEASE DO NOT TRY TO GIVE ME A SHORT ANSWER TO TRY TO GET RID OF ME, I KNOW BETTER. THE CRANKCASE IS FULL OF OIL TO THE CORRECT LEVEL ON THE DIPSTICK AND I USE THE RECOMMENDED 5W30 OIL. WHY AM I HAVING THIS ISSUE? NOTE: I AM DEPLOYED SO PLEASE DON'T TRY TO CONTACT ME BY PHONE. *TR

SERVICE BRAKES, HYDRAULIC
THE METALLIC BRAKE LINE TUBING RUPTURED CAUSING BRAKE FAILURE WHILE TRAVELING 50 MPH ON A DOWNGRADE. THE METAL LINE ABOVE THE REAR AXLE, PASSENGER SIDE, CORRODED THROUGH AND SPEWED BRAKE FLUID ALL OVER. THE CORROSION POINT IS ABOUT 7-10 INCHES FORWARD OF THE JUNCTION WHERE THE BRAKE LINE TRANSITIONS TO RUBBER HOSE THAT GOES TO THE REAR AXLE JUNCTION. THERE IS ALSO AN UNUSUAL AMOUNT OF CORROSION ON THE GAS FUEL FILTER FITTINGS LOCATED JUST FORWARD OF THE GASOLINE TANK. I WAS ABLE TO SLOW AND STOP BY DOWNSHIFTING AND USING THE EMERGENCY BRAKE. BRAKE LINES SHOULD NOT CORRODE AND FAIL IN ANY CLIMATE ON A 9 YEAR OLD TRUCK! THEY SHOULD NOT CORRODE PERIOD. *TR

LEAVING WORK TO GO HOME HIT THE BRAKES TO AVOID A PERSON RUNNING A STOP SIGN. PEDDLE TO THE FLOOR. HAD MY WIFE COME PICK ME UP. ENDED UP REPLACING ALL THE LINES FROM THE ABS BLOCK FORWARD. THE TRUCK HAD ROCKER PANELS REPLACED 3 YEARS AGO DUE TO RUST. THAT IS COSMETIC. BRAKE FAILURE COULD BE FATAL. I LOOKED UNDER THE TRUCK AND NOTICED AN OVERLY ABOVE AVERAGE AMOUNT OF RUST. THE FRAME IS SO BAD IT MAY NOT PASS INSPECTION NEXT YEAR. PLEASE GM TAKE CARE OF US LOYAL (MAYBE NOT MUCH LONGER) GMC OWNERS. *TR

WHILE MY BUDDY WAS BACKING MY BOAT TRAILER AND BOAT INTO THE WATER FOR ME, HE YELLED TO GET OUT OF THE WAY, THE VEHICLE WAS SLIDING DOWN THE BOAT RAMP. HE WAS ABLE TO STOP BEFORE GOING INTO THE WATER. I TOLD HIM I JUST HAD THE BRAKES DONE THIS FALL AND HE SAID THE BRAKE PEDAL WENT STRAIGHT TO THE FLOOR. I GOT IN TO PULL THE TRUCK UP AND THE PEDAL DID GO STRAIGHT TO THE FLOOR. A LARGE PUDDLE OF BRAKE FLUID WAS ON THE GROUND AT THE BOAT LAUNCH. I HAD THE VEHICLE TOWED TO THE REPAIR SHOP AND FOUND THAT THE BRAKE LINES HAD CORRODED SO BAD, THEY RUSTED RIGHT THROUGH AND LOST ALMOST ALL OF THE BRAKE FLUID. THE LINES WERE SO BAD, I NEEDED TO GET THE ENTIRE BRAKE LINE SYSTEM REPLACED. *TR

TRANSMISSION COOLER LINE LEAK COULD LEAK OUT ALL FLUID AND CAUSE TRANSMISSION FAILURE. THE CONSUMER WAS INFORMED THE VEHICLE NEEDED TRANSMISSION COOLER LINES, TRANSMISSION FLUID AND CONDITIONER AT A COST OF $ 822.32. THE SERVICE MANAGER AGREED TO CUT THE BILL TO $411.16. THE CONSUMER CONTACTED GM CUSTOMER SERVICE TO MAKE A COMPLAINT. AFTER AN INVESTIGATION, THE CONSUMER WAS INFORMED BY GM THAT THE DEALER STATED THE FAILURE WAS CAUSED BY THE AGE OF THE VEHICLE AND GM WOULD NOT COVER THE COST OF THE PART. THE CONSUMER STATED THE PART WAS MADE OF DEFECTIVE MATERIALS AND SHOULD HAVE BEEN RECALLED. WHEN THE CONSUMER CONTACTED THE DEALER, THEY STATED THEY HAD NOT MADE A DIAGNOSIS OF THE FAILURE AND THE PARTS WERE SENT TO GM TO BE EXAMINED. UPDATED IVOQ 01/04/12 *JB *TR
