WHEELS
THANKFULLY I WAS DRIVING ON A CITY ROAD AT ABOUT 25-30 MPH. WHEN I HEARD A LOUD SQUEAK AND A LITTLE NOISE. I THOUGHT THAT SOMETHING MUST HAVE FALLEN IN THE BED OF THE TRUCK. I LOOKED IN MY MIRROR AND SAW MY SPARE TIRE LAYING IN THE MIDDLE OF THE LANE. THANKFULLY, THERE WERE NO CARS FOLLOWING. I TURNED AROUND AND FOUND THAT THE CABLE THAT HOLDS THE SPARE TIRE UP UNDER THE BED OF THE TRUCK HAD BROKEN AND DROPPED THE TIRE AND THE COMPONENTS THAT HOLD THE SPARE TIRE IN PLACE WHERE LAYING ON THE PAVEMENT. I NORMALLY DRIVE ON A VERY BUSY INTERSTATE ROAD AT 70 MPH. I CAN NOT EVEN IMAGINE WHAT COULD HAVE HAPPEN THIS HAD HAPPENED ON THAT ROAD! I AM SURE THAT SOMEONE COULD HAVE BEEN KILLED! I HAVE CONTACTED A DEALER AND I AM STILL WAITING TO HEAR WHAT THEY WANT TO CHARGE ME TO FIX THE ISSUE. *JS

STEERING, ELECTRICAL SYSTEM
I HAVE BEEN HAVING TROUBLE STARTING MY 2004 GMC, SOMETIME WHEN I TURNED THE KEY IT WOULD DO NOTHING, I HAD IT TOWED IN AND SPENT OVER $500 TO REPAIR IT, ALTERNATOR, BATTERY ETC, AND IT DID NOT FIX THE PROBLEM. WHEN I GOT IT BACK, AND IT DID IT AGAIN, I FOUND THAT IF I MOVED THE STEERING WHEEL UP AND DOWN WITH THE LEVER, IT WOULD THEN START. YESTERDAY I WENT OUT TO START MY TRUCK IN MY DRIVEWAY, AND THE KEY WILL NOT TURN IN THE IGNITION. IT FEELS LIKE THE IGNITION CAME APART OR SOMETHING INSIDE. THE STEERING WHEEL IS NOT LOCKED. IT IS RIDICULOUS THAT I WILL HAVE TO PAY TO HAVE THIS VEHICLE TOWED IN AGAIN AND PAY TO REPAIR THE IGNITION, WHEN GM HAS BEEN HAVING HUGE PROBLEMS WITH IGNITIONS! I HAVE HAD OTHER PROBLEMS WITH THIS VEHICLE TO INCLUDE A FIRE UNDER THE DASH. MY INSURANCE COVERED IT BECAUSE A FUSE MELTED AND DID NOT DO IT'S JOB, HOWEVER NOW MY SPEEDOMETER DOES NOT WORK, AND THEY WANT ME TO PAY FOR A NEW WIRING HARNESS WHICH I WILL NOT DO. I USE MY GPS TO TRACK MY SPEED! THE REAR TRANSFER CASE WENT ON IT, AND I SPENT $1,800 TO HAVE A NEW ONE INSTALLED. THERE HAVE BEEN OTHER SMALL THINGS, BUT THOSE ARE THE MAJOR PROBLEMS I HAVE HAD OVER THE YEARS. I AM LIKE EVERY OTHER AVERAGE PERSON. I HAD NO IDEA HOW TO GET GM TO FIX THEM, SO I JUST PAID MYSELF! WHEN I WAS RESEARCHING HOW TO REPLACE THE IGNITION, I CAME ACROSS YOUR SITE. I HAVE NO IDEA WHAT I CAN DO ABOUT THIS OR HOW TO GO ABOUT IT. I NEED MY TRUCK AS SOON AS POSSIBLE, SO I WILL PROBABLY GET STUCK PAYING AGAIN! THANK YOU *TR

FUEL SYSTEM, DIESEL
DRIVING FROM GM DEALER FOR TWO MILES CHANGE FUEL FILTER MESSAGE APPEARED AND ENGINE DIED. TOWED TO A DEALER DIAGNOSED AS A HIGH PRESSURE INJECTOR PUMP FAILURE WITH METAL CONTAMINATION TO FUEL SYSTEM. I HAVE FOUND A BULLETIN DATED 2009 FROM EQUIPMENT MANUFACTURERS. THIS JOINT STATEMENT HAS INFORMATION ABOUT THE FUEL USED IN THE USA THAT I WAS NOT AWARE OF AND MAY HAVE AVOIDED THIS FAILURE. THIS IS A VERY EXPENSIVE REPAIR AS I USE MY TRUCK FOR WORK. *TR

EXTERIOR LIGHTING
WORST HEADLIGHT FOR A NEW VEHICLE. I HAVE OWNED VARIOUS GM TRUCKS FROM 1967 TO 2014. NEVER HAVE I OWNED A TRUCK WITH SUCH WORTHLESS HEADLIGHTS LIKE THE PROJECTOR BEAM HEADLIGHTS ON MY 2014 GMC SIERRA 1500 WITH THE ALL TERRAIN PACKAGE. THE PROJECTOR HEADLIGHT ARE VERY DIM AND DO NOT LIGHT THE ROAD MORE THAN 30 FEET AHEAD. AT HIGHWAY SPEEDS (55-70) THE PROJECTOR HEADLIGHTS ARE ONLY LIGHTING A HALF SECOND AHEAD OF YOU. ADDITIONALLY THERE IS NO LIGHTING TO ILLUMINATE THE SHOLDER AT ALL.. YOU MUST DRIVE FULL TIME WITH THE FOG LAMPS ON TO HAVE A SMALL INCREASE IN LIGHTING. WHEN USING THE HIGH BEAMS THERE IS VERY LITTLE EFFECT ON VISIBILITY. EXTREMELY DISAPOINTED IN THE 2014 GMC SIERRA. AND WILL UNLIKELY PURCHASE ANOTHER GM PRODUCT IN THE FUTURE. AT A MSRP OF OVER 50 GRAND I WOULD EXPECT A TRUCK TO HAVE ADEQUATE HEADLIGHT TO LIGHT THE ROAD. WITHOUT THE AFTERMARKET COST TO INSTALL BETTER LIGHTING THE 2014 GMC SIERRA IS VERY UNSAFE TO OPERATE AT NIGHT. *TR

SERVICE BRAKES, HYDRAULIC
WHILE SLOWING TO MAKE A TURN I APPLIED THE BRAKES AND HAD A SUDDEN AND COMPLETE LOSS OF BRAKES. HAD I NOT BEEN ON A SUBURBAN ROAD OR IN TRAFFIC OR A HIGH SPEED HIGHWAY THE SITUATION COULD HAVE BEEN CATASTROPHIC AND RESULTED IN A CRASH. I WAS NEAR MY REPAIRING GARAGE AND MANAGED TO GET THE VEHICLE THERE BY USING THE EMERGENCY BRAKE AND LOW SPEED. IT WAS LESS THAN A MILE. I HAD THIS REPAIRED AT A COST OF $849.27. JUST YESTERDAY (6-30-2014) I WAS PARKED ON A HILL AND AS I RELEASED THE PARKING BRAKE MY FOOT SUDDENLY WENT TO THE FLOOR AND I EXPERIENCED A SECOND LOSS OF BRAKES DUE TO FAILURE OF THE REMAINING TWO BRAKE LINES. I WAS ON A HILL AND HAD ONLY A TINY AMOUNT OF BRAKING POWER. THE VEHICLE IS AT THE GARAGE AND THE COST OF THIS REPAIR HAS YET TO BE DETERMINED. THEY WILL REPLACE THE REMAINING TWO BRAKE LINES. I RECENTLY HAD TO REPLACE THE TRANSMISSION COOLING LINES WHICH RUPTURED AND ARE LOCATED IN A NEARBY LOCATION ON THE VEHICLE. ALL ARE EXPOSED AND UN-SHIELDED. THE MANUFACTURER ADVERTISES THAT THE VEHICLE IS "PROFESSIONAL GRADE" AND "HEAVY DUTY" BUT I FIND BOTH THESE CLAIMS TO BE GREAT EXAGGERATIONS. THESE SITUATIONS HAVE SCARED ME AND I DESIRE TO ACQUIRE A DIFFERENT VEHICLE AS SOON AS I AM ABLE. UNFORTUNATELY, THIS WILL NOT BE SOON. I WILL HAVE TO DRIVE WITH THE FEAR THAT ANOTHER POTENTIALLY CATASTROPHIC PROBLEM COULD DEVELOP AT ANY MOMENT. FORTUNATELY, NEITHER OF THESE INCIDENTS WERE PANIC STOPS.

SERVICE BRAKES
THERE IS NO WARNING THE PEDAL GOES TO THE FLOOR AND YOU DON'T STOP. I HAD A 5TH WHEEL TRAILER HOOKED TO MY 2006 GMC 2500 EXT. CAB LONG BED SIERRA P/U WITH 62,459 MILES ON IT. I WAS ABLE TO STOP IT WITH THE TRAILER BRAKES AND A SCRATCH ON MY FRONT BUMPER FROM A TRACTOR TRAILER THAT WAS IN FRONT OF ME. I HAVE OWNED OVER 200 CARS + TRUCKS SINCE I STARTED DRIVING. I DO ALL MY ONE WORK ON THEM AND I NEVER HAD A BRAKE LINE FAIL, I WILL BE 70 THIS YEAR. IT IS RIDICULOUS FOR AN 8 YEAR OLD TRUCK TO HAVE RUSTED BRAKE LINES TO FAIL. THE WORST PART OF THIS IS THAT NOBODY NOTIFIED THE PUBLIC THAT THIS WAS A PROBLEM WHEN THEY GMC KNOWS ABOUT THIS PROBLEM. I FOUND A GARAGE THAT FIXED THE TWO FRONT LINES. SO WE COULD GET HOME. THEN I INSPECTED THE OTHER LINES AND ORDERED THE COMPLETE SET OF STAINLESS STEEL LINES FROM EBAY, WHEN I REMOVED THE OLD LINES THEY ALL WERE RUSTED AT HIDDEN SPOTS TWO WERE CLOSE TO FAILING. WHY DO THEY HAVE TO WAIT FOR SOME ONE TO DIE BEFORE THEY NOTIFY THE PUBLIC THERE IS A SAFETY PROBLEM. THIS IS GMC AND OUR GOVERNMENT (NHTSA) FAILING THE PEOPLE. *TR
