EXTERIOR LIGHTING
I PURCHASED A 2014 GMC SIERRA IN NOVEMBER OF 2014 AND THE HEADLIGHTS ON OUR TRUCK GIVE YOU VERY LIMITED VISIBILITY, IT IS UNSAFE TO DRIVE AT NIGHT WITH HIGH BEAMS OR LOW BEAMS, I USE MY FOG LIGHTS TO HELP ME SEE BETTER BUT THEY DO NOT HELP MUCH ON DISTANCE. I TRADED IN A 2013 SILVERADO THAT HAD AWESOME HEADLIGHTS FOR THIS TRUCK AND RAISED MY PAYMENT 300$ ONLY TO HAVE A TRUCK THAT I CANT DRIVE AT NIGHT. SOMETHING NEEDS TO BE DONE ABOUT THIS. I HAVE READ MANY COMPLAINTS ON THIS ISSUE AND FEEL THAT GM NEEDS TO CORRECT IT AS SOON AS POSSIBLE BEFORE A SERIOUS ACCIDENT HAPPENS.

SERVICE BRAKES
DRIVING TO WORK ONE MORNING, I NOTICED AS I APPROACHED A STOP SIGN THAT I HAD TO PUSH MY BRAKE PEDAL FURTHER THAN I HAD EARLIER IN MY TRIP. INSTEAD OF CONTINUING ONTO THE FREEWAY I PULLED INTO A STATION AND TESTED THE BRAKES ONLY TO FIND THAT I COULD PUSH THEM ALL THE WAY TO THE FLOOR AND COME TO A GRADUAL, ROLLING STOP. THE TRUCK WAS TOWED TO A SHOP WHERE IT WAS FOUND THAT ONE OF THE METAL BRAKE LINES HAD RUSTED THROUGH. ALL 6 LINES SHOWED SIGNS OF SEVERE RUSTING. ONCE THE LINES WERE REPLACED THE MECHANIC TOLD ME THAT A SECOND LINE HAD RUSTED TO THE POINT THAT HE DID NOT THINK IT WOULD HAVE HELD PRESSURE IF I HAD ONLY REPLACED THE FIRST FAILED LINE. I WAS ADVISED THAT THE BRAKE LINES IN THIS MODEL AND YEAR OF TRUCK WERE KNOWN TO RUST AND FAIL EARLY IN THE LIFE OF THE VEHICLE, ESPECIALLY IN NORTHERN STATES.

UNKNOWN OR OTHER
FRAME AND CROSS MEMBERS CORROSION FOUND WHEN HAVING CAB ROCKER PANELS REPLACED AND PREP-REPAINT CAB. BODY SHOP CALLED ASK ME TO STOP BY HAVE A LOOK AND THAT THEY HAD REMOVED THE BED. I WAS SHOCKED AT THE CROSS MEMBER TUBE THAT REAR SHOCK IS MOUNTED TO IS ALMOST CORRODED COMPLETELY AROUND OVER EXAUST MUFFLER. SHOP OWNER INFORMED ME HE DID NOT HAVE ABILITY TO REPLACE CROSS MEMBER. I AM ALSO CONCERNED ABOUT THE AMOUNT OF CORROSION OVER ALL FRAME-STRUCTURE. WE BOUGHT TRUCK NEW, 50% OF ITS TIME WAS PARKED UNDER CAR PORT. NEW CRATE MOTOR ($5000 INSTALLED) HAS 25,000 MILES. CAB REPAIRS AND PAINT $3000 >. I KEPT IT WELL MAINTAINED. WE HAVE 7 GM VEHICLES, CANNOT HELP TO WONDER HOW MUCH HIDDEN SUPRISES AHEAD? I REPLACED CORRODED BRAKE LINES 2008 BRAKES WENT OUT IN DRIVEWAY STOPPED WITH PARKING BRAKE. THIS IS A SERIOUS SUBSTANDARD STEEL PROBLEM. TOYOTA I UNDERSTAND WAS RECALLED ON THIS SAME ISSUE? THE TRUCK STILL DRIVES AND FEELS LIKE THE FIRST RIDE. ANY HELPFUL INFORMATION WELCOME. THANKS'

POWER TRAIN
THE TRANSMISSION BEGAN TO SLIP. AT TIMES, I HAD TO STOP THE TRUCK AND PUT IN PARK BEFORE IT WOULD ENGAGE IN DRIVE. FINALLY IT LOST ALL BUT 1ST GEAR. TOOK TO DEALER AND TORQUE CONVERTER HAD TO BE REPLACED. GMC MADE ME PAY HALF THE $3200 REPAIR. I DO NOT LIVE IN A COLD CLIMATE. A HEAVY DUTY TRUCK SHOULD NOT BE LOSING THE TRANSMISSION AT LESS THAN 50,000 MILES!

SERVICE BRAKES
I HAVE OWNED MANY GM TRUCKS, AND NEVER HAD ONE WITH SO MANY RUSTED OUT BRAKE LINES. WHY CAN'T THEY MAKE THEM WITH STAINLESS STEEL LINES. THEY SHOULD HAVE A RECALL FOR THIS. WHAT HAPPENS WHEN FRONT AND BACK LINES GO AT THE SAME TIME, I WILL TELL YOU, NO BRAKES ! THIS IS THE WORST ONE WITH THE RUST THAT I HAVE HAD. 3 LINES RUST OUT ON THE GMC 2500 HD (2002) WITH MORE TO COME, I HAVE 25,000 MILES ON THIS TRUCK. THE FIRST LINE WENT ABOUT 15,000 MILES. ALSO I ONLY GOT ABOUT 5,000 MILES ON THOSE FIRESTONE TIRES, CHEAP TIRES COME WITH THIS TRUCK. I HAVE ALSO NOTICED THE FRAME IS RUSTING, HAD TO HAVE THE CABLE REPLACED THAT SHIFTS THE TRUCK INTO GEAR, IT RUSTED OUT. I GO TO THE CAR WASH AND ALWAYS WASH THE UNDERSIDE OF THE TRUCK TO GET ALL THE DIRT AND SALT OFF EVERY CHANCE I GET. WHEN I GOT THE GMC I WAS TOLD BY THE GMC GARAGE NOT TO HAVE THE TRUCK UNDERCOATED BECAUSE IT WOULD VOID THE WARRANTY ON IT. I ALSO HAD TO HAVE THE CABLES REPLACED ON THE TAIL GATE DUE TO RUST. VERY SAD ABOUT THIS GMC TRUCK. EVERYTHING IS RUSTING. I SHOULD HAVE A LOT OF MILES LEFT ON THIS TRUCK, IF IT DOESN'T RUST ITSELF TO DEATH OR GET ME KILLED BECAUSE OF RUSTED OUT BRAKE LINES !

AIR BAGS
PASSENGER AIR BAG LIGHT WENT ON INDICATING THAT THE AIR BAG WAS NOT FUNCTIONAL. TOOK THE VEHICLE TO AN INDEPENDENT REPAIR SHOP AND THEY COULD NOT DIAGNOSE THE PROBLEM. THEN TOOK IT TO A GMC DEALER AND THEY DETERMINED THAT IT WAS DUE TO LOSS OF POWER TO THE AIR BAG MODULE ATTRIBUTED TO CORROSION WITHIN THE UNDER-HOOD FUSE BLOCK.

STEERING
THE STEERING ON THE PICKUP TRUCK STICKS, LOCKS UP FOR A MOMENT THEN FREES ITSELF. I HAVE BEEN HAVING ON AND OFF ISSUES SINCE BUT THE DEALERSHIP IS ALREADY TRYING TO GET OUT OF ANY RESPONSIBILITY ALREADY STATING THIS IS OUT OF WARRANTY AT THIS DATE. SALT LAKE VALLEY GMC HAS BEEN AWARE OF THE ISSUE SINCE DAY ONE. THIS HAS BECOME A SAFTEY ISSUE, THE VEHICLE IN QUESTION IS NOT SAFE TO DRIVE AT THIS TIME AND I AM LEFT HOLDING THE BAG FOR A MYSTERY THEY CANNOT SOLVE (OR GM IS COVERING UP YET ANOTHER PROBLEM) NOTE THIS TRUCK IS THE DURAMAX 2500.
