ENGINE AND ENGINE COOLING, FUEL/PROPULSION SYSTEM
THE FIRST TIME WAS NOV.2014 WHEN THE CHECK ENGINE LIGHT CAME ON SOLID ALONG WITH THE TRACTION CONTROL LIGHT ENGINE POWER WAS REDUCED AND THE ENGINE VIBRATED AND WOULD NOT GO OVER 20 MPH.I LEFT THE TRUCK PARKED FOR 3 DAYS AND WHEN CRANKED THE TRUCK ALL LIGHTS WERE OFF AND THE TRUCK RAN FINE.ONCE IN DEC. 2014 AND ONCE IN JAN.2015 THE SOLID CHECK ENGINE LIGHT CAME ON BUT THE TRUCK RAN FINE AND AFTER A FEW DAYS WENT OFF. THE FIRST WEEK OF FEB. 2015 THE CHECK ENGINE AND TRACTION CONTROL LIGHT CAME ON ENGINE POWER WAS REDUCED AND ENGINE VIBRATION. I WAS ABLE TO DRIVE SLOWLY ONLY TO AN INDEPENDENT MECHANIC THAT I NORMALLY GO TO BECAUSE HE WAS CLOSER THAN THE DEALERSHIP AND I WANTED IT CHECK IMMEDIATELY SINCE THE WARNING LIGHTS WERE ON.HIS CODES SHOWED THE THROTTLE BODY WITH SENSOR NEEDED TO BE REPLACED.HE STATED HE LEFT THE CODES IN EVEN THOUGH THE WARNING LIGHTS WENT OFF BECAUSE HE THOUGHT THIS WORK WAS COVERED UNDER WARRANTY.I IMMEDIATELY CALLED THE DEALERSHIP AND THEY WANTED TO MAKE AN APPOINTMENT FOR THE FOLLOWING WEEK AND WHEN I TOLD THEM ALL THE WARNING LIGHTS HAD WENT OFF THEY STATED IT WOULD PROBABLY BE A WASTE OF TIME TO CHECK ON THEIR COMPUTER. I TOLD THE DEALERSHIP SERVICE DEPT. ABOUT HOW YOU DON'T KNOW WHEN THIS WILL HAPPEN AND WHEN IT DOES YOU ARE BASICALLY STRANDED BECAUSE THE VEHICLE WILL BARELY MOVE. THE NEXT WEEK FEB.11, 2015 IT HAPPENED AGAIN AND ALL 3 TIMES I WAS LUCKY I WAS NOT IN ALOT OF TRAFFIC OR TRAVELING AT HIGH SPEEDS OR ON A STEEP GRADE.IF I WOULD HAVE BEEN THERE MAY HAVE BEEN A ACCIDENT. I HAD TO LEAVE THE TRUCK IN A PARKING LOT AND THE NEXT DAY TOOK IT BACK TO THE INDEPENDENT MECHANIC.I CALLED THE DEALERSHIP AND AGAIN THEY WANTED TO MAKE AN APPOINTMENT AND THEY STATED THE WORK WAS NOT COVERED UNDER WARRANTY SO MY MECHANIC CAME UP WITH THE SAME CODES AND FIXED THE PROBLEM.CALLED GM AND EXPLAINED THE UNSAFE SITUATION AND GOT NO CUSTOMER SERVICE. *TR

EXTERIOR LIGHTING
HEADLIGHT LIGHTING IS USELESS, NIGHT DRIVING IS DANGEROUS. LIGHT OUTPUT IS SO LOW/DIM THAT IT IS EASY TO OUT DRIVE THE HEADLIGHTS. HIGH BEAM IS NO BETTER AS IT JUST DISPERSES THE BEAM ACTUALLY MAKING IT APPEAR DIMMER. SOMETHING NEEDS TO BE DONE TO ADDRESS THIS CONCERN BEFORE SOMEONE GETS INJURED BY THESE UNSAFE HEADLIGHTS. *TR

EXTERIOR LIGHTING
AT HIGHWAY SPEEDS THE VEHICLE LOW BEAM HEADLIGHTS DO NOT PROVIDE SUFFICIENT ILLUMINATION TO OPERATE IN A SAFE MANNER. THIS LACK OF LIGHTING RESULTS IN AN AVOIDABLY UNSAFE PRACTICE OF OVERDRIVING THE HEADLIGHTS. THE HEADLIGHTS SHOULD ILLUMINATE FAR ENOUGH IN FRONT SO THAT IS NOT POSSIBLE TO OVERDRIVE YOUR LIGHTS AT NORMAL HIGHWAY SPEEDS. *TR

EXTERIOR LIGHTING
THE HEADLIGHTS ON THIS VEHICLE ARE HORRIBLE, LOW BEAMS ARE OF NO USE EXCEPT IN THE CITY TRAFFIC AND HIGH BEAMS ARE ONLY SLIGHTLY BETTER. HIGH BEAMS ARE NOT SUFFICIENT FOR DRIVING ON DARK ROADS. HOPEFULLY GM WILL OFFER TO REPAIR/REPLACE THESE BEFORE THERE ARE DEATHS TO REPORT.

ELECTRICAL SYSTEM
I GOT OUT OF MY TRUCK, HAD LEFT THE KEYS IN THE IGNITION, WALKED OVER TO GET SOMETHING OFF THE GROUND AND HEARD THE HORN BLOW. I WALKED BACK OVER TO THE TRUCK TO GET BACK IN AND IT WAS LOCKED. I CALLED ON STAR AND THEY COULDN'T UNLOCK IT SO THEY HAD TO SEND A LOCK-OUT SERVICE TO UNLOCK THE TRUCK. THIS HAS HAPPENED AT LEAST FIVE TIMES IN THE PAST THREE YEARS, THREE IN WHICH ON STAR HAD UNLOCKED IT. *TR

EXTERIOR LIGHTING
I'VE HAD MY 2014 GMC SIERRA FOR NEARLY A YEAR NOW, FIRST NIGHT I HAD IT I COULDN'T BELIEVE HOW POOR THE LIGHT OUTPUT WAS FROM THE HEADLIGHTS. I'VE HAD NUMEROUS GMC SIERRA TRUCKS OVER THE YEARS AND THIS TRUCK BY FAR HAS THE WORSE HEADLIGHTS I'VE EVER HAD IN A TRUCK. THERE ARE A LOT OF PEOPLE ONLINE COMPLAINING, I'M DEFINITELY NOT THE ONLY ONE UPSET WITH HOW POOR THESE HEADLIGHTS ARE. THERE ARE A FEW GUYS IN TOWN WITH THIS SAME TRUCK THEY ALL HATE THE HEADLIGHTS TOO. THESE HEADLIGHTS JUST SEEM VERY DIM, THEY DON'T SHINE THE DITCHES UP VERY WELL, THEY DON'T SHINE AHEAD VERY FAR EITHER. I HAVE BETTER LUCK RUNNING THE HEADLIGHTS ON LOW BEAM AND FOG LIGHTS ON, IT ALMOST SEEMS LIKE LESS LIGHT ON HIGH BEAM SO I RARELY HAVE THEM ON HIGH, I'VE HAD MULTIPLE OCCASIONS WHERE I NEARLY HIT A MOOSE, THESE HEADLIGHTS ARE VERY DANGEROUS I'M WORRIED THAT ONE OF THESE DAYS I'M GOING TO HIT A MOOSE OR WORSE A PERSON! I REALLY HOPE SOMEBODY DOES SOMETHING ABOUT THESE HEADLIGHTS GM DIDN'T LISTEN TO ANYTHING I HAD TO SAY. *TR

EXTERIOR LIGHTING
THE LARGE 8" INTELLILINK RADIO SCREEN IN THIS TRUCK HAS SEPARATE BRIGHTNESS CONTROL FROM THE REST OF THE DASH LIGHTS, INCLUDING THE INSTRUMENT PANEL. DUE TO IT'S SIZE AND COLORED BACKGROUND, THE LCD RADIO SCREEN IS MUCH BRIGHTER THAN THE REST OF THE INTERIOR LIGHTS. THE FACT THAT THE SYSTEM HAS NO NIGHT SCHEME, MEANING IT DOESN'T SHIFT TO A MOSTLY BLACK BACKGROUND AT NIGHT MAKES THIS PROBLEM EVEN WORSE. WHILE IT IS POSSIBLE TO LOWER THE BRIGHTNESS USING A DASH-MOUNTED DIMMER SWITCH, THE DIMMER MUST BE LOWERED TO MINIMUM IN ORDER TO GET THE RADIO SCREEN TO BE A COMFORTABLE BRIGHTNESS LEVEL FOR NIGHT DRIVING. AT THIS POINT, THE INSTRUMENT CLUSTER LIGHTS ARE SO DIM AS TO BE EXTREMELY DIFFICULT TO SEE AND AS A RESULT REQUIRE MUCH MORE TIME AND EFFORT TO READ SPEED INFORMATION. THE ONLY WAY TO COMPLETELY TURN OFF THE RADIO SCREEN IS TO GO THROUGH SEVERAL MENUS INTO SETTINGS AND MANUALLY TURN OFF THE SCREEN. NOT ONLY IS THIS A DANGEROUS DISTRACTION WHILE DRIVING BUT IF ANY VEHICLE SETTING SUCH AS RADIO VOLUME, OR HVAC CONTROLS ARE ADJUSTED, THE SCREEN AUTOMATICALLY TURNS BACK ON AND THE PROCESS MUST BE REPEATED. I HAVE CONTACTED GM SEVERAL TIMES ABOUT THIS ISSUE DUE TO ITS DISTRACTING NATURE WHEN DRIVING AT NIGHT AND HAVE BEEN TOLD REPEATEDLY THAT THE SYSTEM IS "OPERATING AS DESIGNED." I FEEL THIS IS A SAFETY ISSUE SINCE THE BRIGHT LIGHT IN THE CAB RUINS NIGHT VISION WHILE ALSO DISTRACTING THE DRIVER'S EYES FROM THE ROAD. MY RECOMMENDATION IS FOR A SOFTWARE UPDATE FOR THE INTELLILINK/RADIO SYSTEM TO BE DESIGNED TO ADD A BRIGHTNESS SETTING IN THE SYSTEM MENU TO ALLOW DRIVER'S TO SET THE RADIO SCREEN BRIGHTNESS INDEPENDENTLY OF THE INSTRUMENT CLUSTER LIGHTS AND TO ALSO PROGRAM A "NIGHT MODE" COLOR SCHEME THAT WOULD SHIFT FROM THE BLUE ILLUMINATED BACKGROUND USED IN THE DAYTIME TO SOMETHING THAT IS MOSTLY BLACK. *JS

EXTERIOR LIGHTING
THE PROJECTOR STYLE HEADLIGHTS THIS TRUCK IS EQUIPPED WITH ARE INSUFFICIENT FOR SAFE NIGHT DRIVING WHEN NOT IN A CITY DRIVING CONDITION. THE LOW-BEAMS ARE SATISFACTORY FOR LOWER SPEEDS (IE <45MPH) BUT ARE EXTREMELY EASY TO OUT-DRIVE AT HIGHWAY SPEEDS. THE BEAM PATTERN IS ALSO NOT WIDE ENOUGH TO ILLUMINATE ANYTHING OTHER THAN THE AREA DIRECTLY IN FRONT OF THE VEHICLE. THE HIGH BEAMS ARE EVEN WORSE. THE HEADLIGHTS IN THIS TRUCK USE ONE SINGLE FILAMENT BULB FOR EACH HEADLIGHT. WHEN THE HIGH BEAMS ARE TURNED ON, A MECHANICAL SHUTTER OPENS TO ALLOW MORE LIGHT THROUGH THE PROJECTOR LENS. THE LENS IS DESIGNED SUCH THAT THIS ADDITIONAL LIGHT IS AIMED SO HIGH AS TO BE USELESS. PARKED 20FT FROM A WALL, THE CENTER OF THE HIGH BEAM PATTER IS ALREADY SEVERAL FT ABOVE THE BULB LEVEL ON THE WALL. WHEN DRIVING ON A STRAIGHT AND LEVEL ROAD WITH NO TREES, IT IS ACTUALLY IMPOSSIBLE TO EVEN TELL THE HIGH BEAMS ARE ON SINCE THERE IS NO EXTRA BEAM TO ILLUMINATE THE SIDES OF THE ROAD AND THE CENTER BEAM IS POINTED UP INTO THE TREES. *JS

ENGINE, STEERING, SERVICE BRAKES
THE FUEL INJECTION PUMP CP4 HAD A CATASTROPHIC FAILURE AS I WAS DRIVING ON A HEAVILY TRAVELED FOUR LANE HIGHWAY, US RT.20. I LOST POWER STEERING AND BRAKES. I FELT FORTUNATE THAT I WAS NOT TOWING A 16,000 LB. FIFTH WHEEL CAMPER DOWN A MOUNTAIN ROAD.I SAY THIS BECAUSE IT WAS EXTREMELY DIFFICULT TO MAINTAIN CONTROL OVER THE TRUCK STEERING IT AND BRINGING IT TO A CONTROLLED STOP. I HAVE READ ABOUT THESE PUMPS FAILING ON NUMEROUS DIESEL FORD AND GM TRUCKS. I ALSO FEEL IF A WOMAN OR SMALL PERSON HAD THIS HAPPEN TO THEM THE OUTCOME COULD END IN LOSS OF CONTROL RESULTING IN INJURIES EVEN DEATHS. THE ONLY ONE THAT KNOWS THE ACTUAL NUMBER OF PUMPS THAT HAVE FAILED IS THE MANUFACTURERS, WHO WILL NOT SHARE THAT INFORMATION WILLINGLY. *JS
