ENGINE, ELECTRONIC STABILITY CONTROL (ESC), ELECTRICAL SYSTEM
ABOUT 2 MONTHS AFTER WE PURCHASED OUR PRE-OWNED 2009 GMC SIERRA DENALI WE STARTED HAVING PROBLEMS WITH THE ENGINE POWER AND ALL SENSORS GOING OFF. THE SENSORS START GOING OFF THE STABILITY CONTROL CUTS OFF IT SAYS ENGINE POWER REDUCED THEN DOESN'T WANT TO SHIFT AND KILLS IN MIDDLE OF TRAFFIC. IT WILL DO IT FOR A FEW DAYS AND THEN JUST STARTS WORKING RIGHT AGAIN. SO WE NEVER KNOW WHEN IT'S GOING TO HAPPEN OR WHERE WE WILL BE. IT'S LIKE IT'S NOT RUNNING ON ALL CYLINDERS. *TR

SERVICE BRAKES, HYDRAULIC, FUEL SYSTEM, DIESEL
THE FUEL LINES ARE RUSTED THROUGH SPRAYING FUEL TO UNDER SIDE OF TRUCK. THE LINES RUSTED THROUGH WHILE DRIVING FIFTEEN HOURS STRAIT FROM FLORIDA. IF THE FUEL WOULD HAVE HIT THE TAIL PIPE OR DIESEL PARTICULET FILTER WHEN REGENERATING, THERE COULD HAVE BEEN A SERIOUS FIRE. I HAVE BEEN THROUGH AN EXPLOSION AT WORK AND KNOW WHAT IT IS LIKE TO BE BURNED. I ONLY DROVE THIS TRUCK DAILY TWO WINTERS BEFORE I GOT HURT AND LAST WINTER IT WAS IN FLORIDA. I HAVEN'T EVEN CHANGED THE FRONT BRAKES YET BUT THE FUEL LINES ARE SHOT. SHAME ON GM AND SHAME ON NHTSA FOR NOT ADDRESSING THIS. YOU BOTH KNOW THERE IS A PROBLEM WITH BRAKE AND FUEL LINES. HOW MANY PEOPLE NEED TO DIE OR GET HURT OR HOW MANY NOT EVEN REPORTED HAVE BEEN TOUCHED BEFORE YOU ACT. AND BY THE WAY I HAVE A MECHANICS DEGREE FROM YEARS AGO BUT AM NOT A PRACTICING MECHANIC. *TR

SERVICE BRAKES
BRAKES WENT OUT NO WARNING, AFTER LOOKING ON DRIVERS SIDE SEAT UNDER TRUCK WHERE FLUID WAS RUNNING OUT SAW WHERE BRAKE LINE WAS RUSTED AND IT BUSTED. SO I TOOK SEVERAL PICTURES AND CALLED GMC, THEY IN TURN TOWED MY TRUCK TO AUFFENBERG OF CARBONDALE, ILLINOIS AT NO CHARGE. AT THIS TIME I STARTED RESEARCHING THE RUSTED BRAKE PROBLEM AND FOUND WHERE ALAN ADLER (MANAGER PRODUCT SAFETY COMMUNICATIONS) FOR GM SAID ON (ABC NEWS RUSTED BRAKE LINES) WHERE THEY WERE OFFERING A (KIT) TO HAVE THE RUSTED BRAKE LINES REPAIRED FOR A COST TO US OF $500.00. SO NOW TODAY 06/05/2014 MY TRUCK IS DONE AT A COST OF $1188.05 TO ME FOR THE DEALER KNOWS NOTHING OF THIS. I HAVE TRIED TO CONTACT ALAN ADLER THROUGH GM AND NO ONE KNOWS WHO HE IS, I HAVE SENT MANY COMPLAINTS AND TALKED WITH MANY PEOPLE AND NO ONE SEEMS TO KNOW WHAT I AM TALKING ABOUT. MY REF.# [XXX] WITH THE COMPLAINT DEPT. SO IF THIS MAN CAN SAY ON THE NEWS THAT THEY HAVE THIS KIT AND THAT ALL THE DEALERS WERE TOLD ABOUT IT HOW CAN THEY LIE AND CHARGE THE PEOPLE WHAT THEY WANT. THANK YOU INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TRUCK IS BRAND NEW AND HAS A BAD SHAKE IN THE REAR END AT 70-85 MPH THAT THE DEALERSHIP CANNOT FIX. I BELIEVE THIS SHAKE COULD LEAD TO PREMATURE WEAR OF PARTS OR A FAILURE AT HIGHWAY SPEEDS THAT COULD CAUSE A CRASH. *TR

SERVICE BRAKES
BRAKES FAILED WITHOUT WARNING AND VEHICLE WOULD NOT STOP. PULLING INTO CAR WASH AND WHEN BRAKES WERE APPLIED THE PEDAL WENT TO THE FLOOR AND THE TRUCK WENT OUT THE OTHER SIDE OF THE CAR WASH. COULD HAVE BEEN VERY DANGEROUS AS I PULL AN EQUIPMENT TRAILER WITH 7000 POUNDS ON IT AND IT WOULD HAVE BEEN IMPOSSIBLE TO STOP. I WILL NEVER OWN A GM PRODUCT AGAIN. THIS IS UNACCEPTABLE. *TR

I WAS DRIVING APPROX 35 MPH WHEN A DOG RAN IN FRONT OF MY VEHICLE. I APPLIED THE BRAKES TO AVOID HITTING THE DOG. A MOMENT LATER I WENT TO APPLY BRAKES TO SLOW DOWN FOR AN UNFAMILIAR TURN AND MY PEDAL WENT TO THE FLOOR. I MANAGED TO DOWNSHIFT TO COME TO A STOP AND UPON INSPECTION, NOTICED A HOLE IN MY DRIVERS SIDE REAR BRAKE LINE. ALL OF THE BRAKE LINES HAVE A SEVERE AMOUNT OF RUST. THE BUNDLE OF LINES RUNNING ALONG THE FRAME ON THE DRIVER'S SIDE ARE THE WORST. *TR

SERVICE BRAKES
I HAD JUST HAD THE TRUCK INSPECTED. WAS DRIVING HOME AND TWO BLOCKS FROM THE INSPECTION STATION WHEN I CAME TO A RED LIGHT. WHEN I STEPPED ON THE BRAKES THE PEDAL WENT TO THE FLOOR. FORTUNATELY I REACTED QUICKLY ENOUGH TO USE THE PARKING BRAKE TO STOP THE TRUCK AND KEEP FROM REAR ENDING THE CAR THAT WAS ALREADY STOPPED. AFTER PULLING INTO PARKING LOT AND INSPECTING THE BRAKES I NOTICED A PUDDLE UNDER THE FRONT LEFT OF THE TRUCK. LOOKING CLOSER I FOUND THE BRAKE LINE HAD RUSTED THROUGH. I RETURNED TO THE SHOP WHERE I HAD THE INSPECTION DONE. HE REPAIRED THE ONE LINE THAT HAD BURST. I WAS INFORMED THAT THE OTHER LINES LOOKED RUSTED AND READY TO BURST AT ANYTIME. *TR

SERVICE BRAKES
I HAD TOWED MY BOAT ON THE INTERSTATE FOR 2 HOURS TO A LAKE. UPON REACHING THE DESTINATION I WAS ATTEMPTING TO LAUNCH THE BOAT AT THE BOAT RAMP. WHILE I WAS BACKING MY BOAT TRAILER INTO THE WATER I WAS USING THE BRAKES TO EASE DOWN THE RAMP. TWO FAMILY MEMBERS WERE IN THE BOAT TO BACK IT OFF THE TRAILER ONCE IN THE WATER. THE PEDAL SUDDENLY WENT COMPLETELY TO THE FLOOR, I STEPPED ON THE EMERGENCY BRAKE TO STOP THE TRUCK FROM ROLLING INTO THE WATER. I GOT OUT AND SAW A LARGE PUDDLE OF BRAKE FLUID UNDER THE TRUCK ON THE DRIVERS SIDE JUST BEHIND THE FRONT WHEEL AREA. I GOT IN THE TRUCK TO SEE IF THE BRAKES COULD BE APPLIED AGAIN BUT WENT COMPLETELY TO THE FLOOR. IN ORDER TO GET THE TRUCK, TRAILER AND BOAT OFF THE RAMP I HAD TO PUT THE TRUCK IN DRIVE, QUICKLY RELEASE THE EMERGENCY BRAKE AND APPLY THE GAS TO PREVENT TRUCK FROM ROLLING BACKWARDS. UPON LOOKING UNDER THE HOOD I FOUND THE BRAKE LINE WAS RUSTED IN A CLIP AND HAD RUPTURED WHERE THE LEFT FRONT WHEEL BRAKE LINE WAS RETAINED IN A CLIP ON THE DRIVERS SIDE FRAME JUST NEXT TO THE STEERING COLUMN. SINCE IT WAS EARLY ENOUGH I WAS ABLE TO GET THE TRUCK TOWED TO A LOCAL MECHANIC TO GET THE RUPTURED LINE REPLACED. ON 5/29/2014 WHILE MOVING THE TRUCK IN THE DRIVEWAY THE BRAKE LINE FOR THE RIGHT FRONT WHEEL HAS NOW RUPTURED, UPON INSPECTION THE RUPTURE IS IN THE EXACT SAME LOCATION WHERE THE BRAKE LINE IS RETAINED IN THE CLIP ATTACHED TO THE FRAME ON THE FRONT DRIVERS SIDE NEXT TO THE STEERING COLUMN. AT THIS POINT I CAN ONLY ASSUME I WILL NEED TO REPLACE ALL THE BRAKE LINES ON THE VEHICLE. IF THIS HAD HAPPENED ON THE INTERSTATE OR HAD TO MAKE AN EMERGENCY STOP DURING THE INITIAL INCIDENT I WOULD HAVE LIKELY HIT SOMEONE, LOST MY BOAT AND INJURED OR KILLED MYSELF OR FAMILY MEMBERS. BRAKE LINES SHOULD NOT RUST LIKE THIS IN FL AND THE LOSS OF ONE BRAKE LINE SHOULD NOT ELIMINATE YOUR ENTIRE BRAKING SYSTEM TO ALL FOUR WHEELS. *TR

POWER TRAIN, ELECTRICAL SYSTEM, AIR BAGS
WITHIN 4 MONTHS OF PURCHASE, WAS DRIVING AT APPROX. 25 MPH WHEN TRANSFER CASE SHIFTED INTO 4 HIGH ON IT'S OWN. SHUT OFF VEHICLE, RESTART AND ABLE TO PUT BACK INTO 2 WHEEL DRIVE. HAPPENED ON AND OFF FOR A LITTLE MORE THAN A MONTH WHEN IT WENT TO 4 LO WHILE DRIVING AT 30 MPH THROUGH TOWN. UNABLE TO RESET. LIMPED IT THE 2 MILES TO DEALERSHIP FOR DIAGNOSIS. COST ME $1200 TO HAVE THE TRANSFER CASE REBUILT. SMOKED THE CLUTCH PACK, BURNED OUT 2 BUSHINGS AND BENT SHIFT SHAFT. HAD SECOND ISSUE OF SHIFTING ON IT'S OWN, MAY 15TH, 2014. THIS TIME IT COST ME $500 FOR THE SHIFT MOTOR TO BE REPLACED. SECOND PROBLEM, SPEEDOMETER READING INCORRECTLY OR NOT AT ALL. BEEN GOING ON FOR ABOUT 3 YEARS SPORADICALLY (APPARENTLY THE LITTLE DRIVE "MOTOR" ON THE BACK OF THE INSTRUMENT CLUSTER, $300 REPLACEMENT OR, FOUND A COMPANY TO REBUILD WITH NEW "MOTORS" FOR UNDER $200). PASSLOCK ISSUES STARTED IN JAN 2014, HAS LEFT ME STRANDED A COUPLE TIMES NOW. CAN'T GET A GOOD ANSWER FROM DEALER AS TO HOW TO REPAIR OTHER THAN "BRING IT IN AND WE'LL HOOK IT TO OUR DIAGNOSTIC SYSTEM" (I.E. PAY US LOTS OF MONEY). ALSO HAVING ISSUE WITH CHECK ENGINE LIGHT ON CONSTANTLY. INTERMITTENT ENGINE MISS ON MULTIPLE CYLINDERS. ROUGH IDLE, CRAPPY MILEAGE, BUT NOT DOWN ON POWER. MISS SEAMS TO GO AWAY OFF IDLE AND NOT NOTICEABLE UNDER LOAD. NEW PLUGS, WIRES, ETC, ETC, ETC.... HAVEN'T FIGURED THIS ONE OUT YET. SAME ANSWER FROM DEALER (PAY US MORE MONEY PLEASE). LASTLY, AIR BAG LIGHT CAME ON IN DEC OF 2012. NEVER CRASHED OR BUMPED BUT HAD TO REPLACE LEFT FRONT AIR BAG SENSOR. LOVE THE TRUCK, CURRENTLY HAS 154000 MILES BUT I'M GETTING FRUSTRATED WITH ALL THE LITTLE ELECTRICAL "GLITCHES" AND THE DEALER WON'T HELP A BIT WITHOUT THE NORMAL ANSWER, "BRING IT IN AND WE'LL HOOK IT TO OUR DIAGNOSTIC SYSTEM". IT'S DANG NEAR $200 (DIAGNOSTIC CHARGE) JUST TO GET MY TRUCK IN AND OUT WITHOUT EVEN GETTING ANYTHING REPAIRED! *TR
