SERVICE BRAKES
AFTER HAVING A GM DEALER PERFORM OIL CHANGE, PERHAPS 1/4 MILE DOWN THE STREET FROM THEIR FACILITY ENCOUNTERED TRAFFIC STOPPED AT AN INTERSECTION IN FRONT OF ME. APPLIED THE BRAKES TO FIND THAT THEY FELT MUSHY, AND BEFORE COMPLETELY STOPPING WENT TO THE FLOOR. I USED THE PARKING BRAKE TO BRING THE VEHICLE TO A STOP WITHOUT CRASHING INTO THE CARS IN FRONT OF ME. WHEN THE LIGHT TURNED GREEN I NURSED THE VEHICLE INTO A PARKING LOT USING THE PARKING BRAKE AND LOOKED UNDER THE HOOD AND COULD FIND NO ISSUE, THE WEATHER WAS VERY WET AND SLOPPY, AND LIGHT SNOW SO I COULD NOT SEE THE TELL TALE FLUID LEAKAGE FROM A BRAKE LINE. BECAUSE I HAD LOST ALL BRAKING I ASSUMED THAT THE MASTER CYLINDER HAD FAILED. I HAD CHANGED ALL CALIPERS, ROTORS AND PADS SEVERAL MONTHS BEFORE, AND AT 140,000 THOUGHT THAT THE MASTER CYLINDER FAILING WOULD BE UNUSUAL, BUT THE ONLY THING THAT WOULD CAUSE COMPLETE FAILURE. AFTER REPLACING THE MASTER I ATTEMPTED TO BLEED THE SYSTEM ONLY TO FIND THAT THE PROBLEM REMAINED. NOW THAT THE UNDER HOOD AREA WAS COMPLETELY DRY IT WAS CLEAR THAT THE FAILURE WAS RUST THROUGH AT A POINT THE LINE TO THE LEFT FRONT WHEEL WAS IN CONTACT WITH THE FRAME RAIL BELOW THE MASTER CYLINDER. THE OIL CHANGE HAD PROBABLY CAUSED MOVEMENT OF THE LINE RESULTING IN THE FAILURE. MOVING SOME OF THE OTHER LINES MADE IT APPARENT THAT ALL OF THE HARD LINES WERE SHOT. THE SLIGHTEST MOVEMENT CAUSED THEM TO FRACTURE. WORSE THAN THAT, THEY WERE ALL ENCASED IN A "SHELL" OF RUST FROM ONE END TO THE OTHER, CONCEALING HOW FRAGILE AND DANGEROUS THEY REALLY WERE. REPAIR ESTIMATES WERE ANYWHERE FROM $800 (LOCAL MECHANICS) TO $3,400 (GM DEALER). LOVELY. I HAD A 1994 S10 BLAZER THAT I SOLD A COUPLE OF YEARS AGO WITH 290,000 MILES ON IT, ORIGINAL BRAKE LINES AND ALL. CHANGED THE LINES MYSELF IN A WEEKEND FOR $120.00, THE GM PARTS GUY NEW EXACTLY WHAT I NEEDED AND HAD THE "KIT" IN STOCK, WHAT A SURPRISE. *TR

EXTERIOR LIGHTING
THE FRONT HEADLIGHTS ARE INSUFFICIENT FOR SAFETY. THEY DO NOT LIGHT THE ROAD SUFFICIENT TO SEE OBJECTS IN ROAD ABOVE A SPEED OF 50 MPH. THESE ARE SINGLE BULB PROJECTOR HEADLIGHTS AND MY OLD 2001 CHEVY SILVERADO HAS MUCH BETTER LIGHTS. GMC SHOULD REPLACE THE LIGHTS WITH DUAL BEAM LIGHTS OR ADD ON A SUPPLEMENTAL LIGHT SYSTEM. *TR

I WAS LEAVING A PARKING LOT, AND AS I HIT MY BRAKES, THERE WERE NO BRAKES. I LIMPED HOME, USING THE E-BRAKE AND TRANSMISSION TO KEEP THE TRUCK UNDER CONTROL. UPON INSPECTION I FOUND THE FRONT BRAKE LINE RUSTED AND LEAKING. *TR

ELECTRICAL SYSTEM
TODAY WHEN I PARKED MY GMC SIERRA 2500HD, I TURNED OFF THE KEY SWITCH AND I NOTICED MY BLOWER MOTOR WAS STILL RUNNING. AFTER A SHORT PERIOD OF TIME I SMELT SOMETHING BURNING. I WENT OUT UNDERNEATH THE HOOD OF MY VEHICLE LOCATED THE FUSE BOX AND REMOVED THE 40 AMP BLOWER MOTOR FUSE AND THAT SHUT DOWN THE HEATER AND THE SMELL STARTING GOING AWAY. IT WAS 19 DEGREES HERE IN OKLAHOMA AT THE TIME OF INCIDENT. I DID SOME RESEARCH ON THE INTERNET AND GOT SEVERAL HITS ABOUT GMC TRUCKS THAT EXPERIENCED THE SAME ISSUE EXCEPT SOME OF THE VEHICLES BURNED COMPLETELY TO THE GROUND. I ALSO GOT INFORMATION FROM THE INTERNET THAT GENERAL MOTORS OF CANADA RECALLED ALL THERE GM PRODUCTS THAT HAD THE SAME BLOWER MOTOR ASSEMBLY. I FILED A COMPLAINT WITH GENERAL MOTORS, DETROIT. THEY SAID THEY HAD NO RECALLS. *TR

ELECTRICAL SYSTEM, STEERING, STRUCTURE:BODY
AFTER RETURNING FROM A DAY OF SHOPPING, I PARKED MY TRUCK AT THE BACK, LIKE ALWAYS. I HAD BEEN NOTICING OIL SPOTS FOR THE LAST FEW DAYS BUT CHALKED IT UP TO AGE AND MILEAGE OF THE TRUCK. AFTER ABOUT TWO HOURS I SAW SMOKE FROM THE BACK AREA WHERE I PARKED. I RAN OUTSIDE TO CATCH TO MY SURPRISE! MY TRUCK WAS ON FIRE, I AS QUICKLY AS POSSIBLE, GRABBED THE GARDEN HOSE AND PUT OUT THE FIRE! I REALIZED AS I LOOKED, THAT THE FIRE HAD STARTED AT THE AREA UNDER THE HOOD WHERE THE FUSES, AND WIRING WERE LOCATED. AS I SLOWLY REBUILT MY TRUCK, I REALIZED THAT THE FIRE WAS NOT THE ONLY PROBLEM THAT I HAD! THE FACT OF THE MATTER WAS THAT IF THE FIRE HAD NOT SHUT MY TRUCK DOWN, THERE WERE A WHOLE ARRAY OF OTHER PROBLEMS THAT I WOULD OF HAD TO REPAIR.

SERVICE BRAKES
MULTIPLE INCIDENCES OF STEEL BRAKE LINE CORROSION, RESULTING IN LOSS OF FLUID PRESSURE, AND THEREFORE LOSS OF BRAKING ABILITY. THIS HAS HAPPENED 3 DIFFERENT TIMES ALREADY. LUCKILY I DRIVE COUNTRY ROADS WITH LITTLE OTHER TRAFFIC.OBVIOUSLY THIS IS A REPETITIVE AND SERIOUS ISSUE FOR MANY OTHER OWNERS OF THESE VEHICLES, AS EVIDENCED BY THE SHEER NUMBER OF COMPLAINTS REGARDING THE SAME ISSUE FILED TO NHTSA FOR THIS VEHICLE. DOES NHTSA EVEN READ OR EVALUATE THE VOLUME AND SERIOUSNESS OF COMPLAINTS ON THE SAME ISSUE? HOW MANY LIVES MUST BE LOST BEFORE THIS BECOMES A RECALL? *TR

SERVICE BRAKES
AS I WAS TRAVELING ABOUT 35MPH APPROACHING A RED STOPLIGHT I PROCEEDED TO PRESS THE BRAKE PEDAL ALL THE WAY TO THE FLOOR, WITH NO BRAKING OF THE VEHICLE. LUCKILY I WAS ABLE TO QUICKLY SHIFT THE VEHICLE INTO NEUTRAL AND ENGAGE THE EMERGENCY BRAKE AND AVOID COLLISION. AFTER FURTHER INSPECTION I FOUND THE HARD BRAKE LINE RUNNING TO THE FRONT LEFT WHEEL HAD RUPTURED CAUSING THE LOSS OF BRAKE FLUID. THE LINE RUPTURED IN AN AREA WHERE IT WAS SEVERELY CORRODED AND UPON INSPECTION, THE OTHER HARD BRAKE LINES OF THE SYSTEM LOOKED SEVERELY CORRODED ALSO. ALL WILL HAVE TO BE REPLACED! THIS FAILURE COULD HAVE HAD A VERY BAD CONSEQUENCES AT A HIGHER SPEED, CLOSER PROXIMITY TO OTHER VEHICLES, OR WITH A LESS EXPERIENCED DRIVER! *TR

EXTERIOR LIGHTING
I HAVE TWO 2014 GMC SIERRAS WITH VERY WEAK HEADLIGHTS. CALLED GM AND THEY SAID NOBODY HAS COMPLAINED. THEY LIED. WAKE UP GM AND SMELL THE ROSES BEFORE SOMEONE IS HURT OR KILLED. THE HEADLIGHTS LOOK GREAT BUT WORK BAD. FEEL LIKE IT WILL BE FOREVER BEFORE THEY DO ANYTHING SO I ADDED MY OWN AUX. LIGHTS. MY I CAN SEE AGAIN. SPENT 400.00 DOLLARS ON 45,000 DOLLAR TRUCK SO I CAN DRIVE SAFETY AT NIGHT. 2014 CHEVYS HAVE DUEL HEADLIGHTS. MUST BE BETTER. FIX THE PROBLEM GM. MY FIRST CAR, A 1962 COMET HAD BETTER LIGHTS.

EXTERIOR LIGHTING
I DISCOVERED ONLY AFTER BUYING THIS VEHICLE THAT THE HEADLIGHTS ARE ABSOLUTELY TERRIBLE, AND CLEARLY AN IMMEDIATE SAFETY HAZARD. THEY ARE A "NEW" PROJECTOR BULB STYLE - SINGLE BULB WITH NO INDEPENDENT HIGH BEAM. THE LIGHT IS DIM ON BOTH HIGH AND LOW BEAMS, VERY NARROW, AND WHEN THE LOW BEAMS ARE AT THE RIGHT HEIGHT THE HIGH BEAMS ARE UP IN THE AIR. I THOUGHT AT FIRST THEY WERE JUST POORLY ADJUSTED, BUT THE DEALERSHIP WAS UNABLE TO IMPROVE THE SITUATION. THEY DID NOT REVEAL TO ME THAT THERE HAVE BEEN NUMEROUS OWNER COMPLAINTS ABOUT THESE LIGHTS, EASILY FOUND BY DOING AN INTERNET SEARCH. THERE SHOULD BE AN IMMEDIATE RECALL AND FIX ON THESE LIGHTS. ACCORDING TO INTERNET REPORTS, THE TRADITIONAL TWO INDIVIDUAL BEAM HEADLIGHTS ON THE 2014 CHEVROLET SILVERADO ARE APPARENTLY FINE. *TR

ENGINE, FUEL/PROPULSION SYSTEM
ENGINE STOPPED RUNNING, DASH GAUGES BLANK. I MANAGED TO PULL OVER WITHOUT POWER BRAKES OR STEERING! AFTER A FEW MINUTES I WAS ABLE TO RESTART WITH "REDUCED ENGINE POWER, TRACTION CONTROL OFF, AND STABILITRAC" PROBLEMS DISPLAYED ON DASH. I WAS A MILE FROM HOME IN -10F TEMPS! I PULLED IT INTO MY SHOP. DTC CODE P2135 WHICH HAS TO DO WITH THROTTLE POSITION SENSOR. THE DEALER HAS A 2 WEEK DELAY IN GETTING INTO THEIR GARAGE! I FOUND OUT THAT THE THROTTLE BODY/SENSOR IS NOT COVERED UNDER WARRANTY. SO WITH THE COST OF A TOW (CAN'T TRUST THE TRUCK TO MAKE TO DEALER) PLUS THE PART COST, I WILL REPAIR IT MYSELF. THE REASON FOR THIS LETTER, I DISCOVERED THAT THIS HAS HAPPENED TO OTHER GMC TRUCK OWNERS. THEIR VEHICLE QUIT IN THE SAME MANNER. I THINK THAT "REDUCED POWER" IS NOT THE SAME AS NO POWER!!! I WONDER WHAT WOULD HAVE HAPPENED TO ME IF I WAS ON THE FREEWAY DURING RUSH HOURS??? BE PREPARED FOR SOME CREATIVE DRIVING! *TR

EXTERIOR LIGHTING
OF ALL THE VEHICLES I HAVE OWNED, THIS 2014 GMC HAS THE WORST HEADLIGHTS OF THEM ALL.. $47,000 AND BASICALLY A BIC LIGHTER ON THE FRONT OF THE TRUCK FOR LIGHTS.. WHILE OUT DRIVING ON MY WAY BACK FROM FORT KENT, WITH THE TRUCK ON HIGH BEAM I NEARLY HIT A MOOSE THAT I DIDN'T SEE UNTIL I WAS RIGHT ON IT DUE TO NOT HAVING ENOUGH LIGHT DOWN THE ROAD.. HAVE TO DRIVE 40 NOT TO OUTRUN THE HEADLIGHTS. VERY VERY FRUSTRATING AND THE DEALER TELLS US THAT GM KNOWS ABOUT IT BUT HAS NO FIX.. *TR

WHILE DRIVING IN TOWN AT 25 MPH, ALMOST HIT A PEDESTRIAN WHO WAS CROSSING THE ROAD DUE TO INSUFFICIENT HEADLAMPS ON THE TRUCK. THIS WAS EVER WITH THE FOG LAMPS ON WHICH SEEM TO PUT OUT MORE LIGHT THEN THE HEADLIGHTS.. EXTREMELY DANGEROUS... HAVE TO RELY ON THE STREET LAMPS TO SEE WHERE WE ARE GOING WHEN DRIVING IN TOWN.. DISAPPOINTED TO MY WITS END THAT THE DEALER TELLS ME THAT THERE ISN'T ANY FIX FOR THIS YET. *TR

SERVICE BRAKES
I WAS DRIVING DOWN THE HIGHWAY IN MY 2000 GMC SIERRA TRUCK WHEN I APPLIED THE BRAKES AND THE PEDAL WENT TO THE FLOOR. I COULDN'T STOP AT THE RED LIGHT, SO I HAD TO MAKE A QUICK LEFT TURN, ACROSS ON ONCOMING TRAFFIC INTO A PARKING LOT BEFORE I COULD GET THE CAR STOPPED. THIS IS THE SECOND TIME MY BRAKES FAILED AND IN BOTH CASES IT WAS BECAUSE THE STEEL BRAKE LINES ROTTED OUT. I'VE OWNED MANY GM VEHICLES AND NEVER HAD TO REPLACE THE STEEL BRAKE LINES, NOT EVEN ON MY 1969 OLDS CUTLASS THAT I STILL OWN. I READ ABOUT OTHERS HAVING THE SAME PROBLEM AND SUPPOSEDLY GM DID NOT RECALL. BUT WAS GOING TO REPLACE PARTS AND LABOR FOR $500. I CALLED GMC AND THEY SAID THEY DIDN'T KNOW OF THIS AND I CALLED 2 DEALERS AND THEY DIDN'T KNOW OF THIS KIT EITHER. SO, I GUESS I HAVE A BIG BILL ON MY HANDS. CHEAP BRAKE LINES WERE USED BUILDING THIS TRUCK, AND BRAKES ARE PRETTY IMPORTANT TO STOP. I'M LUCKY I WAS ABLE TO GET OUT OF THIS SITUATION WITHOUT WRECKING. *TR

EXTERIOR LIGHTING
NO ACCIDENT. (YET) HEAD LIGHTS ARE PATHETIC. RANGE OF VISION AT NIGHT IS TOTALLY UNACCEPTABLE. THERE IS NO DIFFUSION OF LIGHT. ONLY LIGHT IS ON A STRAIGHT HORIZONTAL LINE. CAUSES A VERY TENSE DRIVING SITUATION ON ANY DARK ROAD. THE LIGHTING ON THE PERIPHERY IS VIRTUALLY NON-EXISTENT BUT MARGINALLY IMPROVED IF FOG LIGHTS ARE LEFT ON ALL THE TIME. MANY COMPLAINTS HAVE ALREADY BEEN FILED. CANNOT UNDERSTAND WHY GMC HAS NOT BEEN COMPELLED TO HAVE A RECALL TO COME UP WITH A REAL SOLUTION. IT DOES NOT APPEAR TO BE A QUESTION OF ADJUSTING THE CURRENT LIGHTING ARRANGEMENT. THIS SHOULD BE A PRIORITY RECALL. DANGEROUS TO DRIVE VEHICLE AT NIGHT. *TR
