2014 GMC Sierra Problems

THE VEHICLE LIGHTS ARE VERY DIM EVEN WITH THE HIGH BEAMS ON. WHILE DRIVING AT NIGHT CAN BARELY SEE IN FRONT OF ME. THESE ARE A HAZARD TO ME AND OTHERS, SINCE NOT BEING ABLE TO SEE A GOOD DISTANCE IN FRONT OF THE VEHICLE MAKES HARD TO SEE PEDESTRIANS, ANIMALS OR DEBRIS IN THE ROAD AT NIGHT.

CAN NOT SEE THE ROAD WITH THE LIGHT OUTPUT WITH THESE FACTORY HEADLIGHT

The contact owns a 2014 GMC Sierra. The contact stated that while making a right turn into the driveway, the steering wheel had become stiff. No warning light had illuminated. The vehicle was no longer being driven since the steering wheel was too stiff and required excessive force causing control to be lost while driving. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 105,000.

THE TRUCK WAS AVERAGING ABOUT 20 MPG BUT SHIFTING ERRATICALLY LIKE IT COULDN'T DECIDE WHAT GEAR TO BE IN. AFTER USING THE 4WD THE FIRST TIME THE MPG DROPPED OFF TO ABOUT 17 AND HAS BEEN DECLINING STEADILY CURRENTLY I GET 14 TO 15 MPG AND DRIVE 150 MILES PER DAY MOSTLY HIGHWAY. I HAVE TAKEN IT BACK TO THE DEALER TWICE THEY SAID THE COMPUTER COULDN'T GET USED TO MY DRIVING STYLE AND REPROGRAMMED THE COMPUTER. WHEN I TOOK IT BACK ABOUT THE MILEAGE A GUY CAME OUT AND SAID HE COULD TELL IF SOMETHING WAS STUCK AND SWITCHED THE 4WD A FEW TIME AND SAID IT WAS FINE. MY MPG IS GETTING WORSE AND IT SLAMS IN AND OUT OF GEAR 2-3 TIMES IN A MATTER OF SECONDS WHILE SUSTAINING A STEADY HIGHWAY SPEED ON A FLAT SURFACE. *TR

THERE IS A EXTREMELY DANGEROUS ELECTRICS ISSUE WITH MY 2014 GMC SIERRA 1500 ALL TERRAIN. IN THE LAST 18 MONTHS MY TRUCK HAS LOCKED THE STEERING AT LOW SPEED WHILE TURNING 8 TIMES. (I COULD HAVE EASILY BROKEN A FINGER A LOST CONTROL OF MY TRUCK) .ON 5 OF THE TIMES I HAD STEERING ISSUE THE TRUCK HAD NO POWER TO ANYTHING INCLUDING KEY FOBS FOR A PERIOD OF 10 TO 15 MINUTES. THEN THE TRUCK WILL POWER UP AGAIN. FORTUNATELY THESE ISSUES HAVE OCCURRED AT LOW SPEED. THIS HAS HAPPEN 8 TIMES IN THE LAST 18 MONTHS . IT HAS BEEN TO DEALERSHIP FOR SERVICE REGARDING THIS ISSUE THEY CHANGED THE BATTERY AFTER ONLY 18 MONTHS (10/2015) THE ISSUE OCCUR AGAIN 2 DAYS AGO WHILE TRAVELING ON THE FREEWAY AT 70 MPH MY TRUCK SHUT DOWN NO POWER THEN IN LESS THAN A SECOND IT POWERED UP AGAIN ALL THE SETTING ON MY RADIO, CLIMATE CONTROL CHANGED.THAT DAY I STOPPED TO GET GAS GOT BACK IN MY TRUCK PULLED AWAY FROM THE PUMP THE STEERING LOCKED TRUCK SHUT DOWN AGAIN FOR 20 MINUTES. THIS TRUCK IS CURRENTLY AT A DEALERSHIP THEY STILL CAN NOT DIAGNOS THE ISSUE. I'M EXTREMLY CONCERN THAT SOMEONE COULD BE SERIOUSLY INJURED OR KILLED IF THIS WAS TO HAPPEN WHILE OPERATING THIS TRUCK. I DID SEE THAT MAY OTHER OWNER OF GMC SIERRA HAVE EXPRESSED SIMILAR CONCERNS. THE ISSUES NEEDS TO BE ADDRESSED IMMEDIATELY. AS FOR MYSELF I PLAN TO THIS TRUCK AFTER THE DEALERSHIP ATTEMPTS ANOTHER REPAIR.

THE VEHICLES HEADLIGHTS ARE DANGEROUSLY INEFFECTIVE. THEY RARELY ILLUMINATE THE DISTANCE BETWEEN 2 TELEPHONE POLES. THE INEFFECTIVENESS OF THE HEADLIGHTS IS AMPLIFIED ON HILLS OR ON ANY TURN. THE DURING THE TRANSITION FROM DECLINE TO INCLINE, YOU SOMETIMES HAVE BARELY A TRUCKS LENGTH OF ILLUMINATION. ANY CORNER ON A DARK ROAD REQUIRES A SEVERE DECREASE IN TRAVEL SPEED TO AVOID OVER DRIVING THE LIGHTS. I HAVE NEVER DRIVEN A VEHICLE THAT MADE ME FEEL MORE APPREHENSIVE TO GET BEHIND THE WHEEL AFTER DARK. I VISITED THE DEALER WHO EXECUTED A TSB THAT INCREASED HEADLIGHT VOLTAGE AND REPLACED THE BULBS. IT MADE A NEGLIGIBLE IMPROVEMENT AND LEFT THE VEHICLE STILL UNSAFE AT NIGHT. I FREQUENTLY TRAVEL ON RURAL ROADS WITH NO STREET LIGHTS. I HAVE ALMOST HIT WILDLIFE TOO MANY TIMES TO COUNT DUE TO THE POOR VISIBILITY CAUSED BY THESE DANGEROUS HEADLIGHTS. TRAVEL OVER 30 MPH ON DARK COUNTRY ROADS WITH A LEGAL SPEED LIMIT OF 50 IS ILL ADVISED DUE TO THE INEFFECTIVENESS OF THE HEADLIGHTS.

THE FACTORY INSTALLED RUNNING BOARDS ARE UNSAFE. THE TREADS NEED TO BE LARGER, MORE AGGRESSIVE AND ROTATED 90^. AS THEY ARE THEY ARE SIMPLY SKID PADS WHEN WET OR FROZEN. YOU SIMPLY NEED TO TRY AND ENTER OR EXIT THE VEHICLE AND SEE HOW EASILY YOUR FOOT SIDES OFF CAUSING THE PERSON THE FALL. I HAVE TAKEN SEVERAL SLIPS/FALLS. TODAY I HIT THE BACK OF MY HEAD ON THE DOOR JAM. JUST ROTATING THE TREAD NINETY DEGREES WOULD HELP.

TL* THE CONTACT OWNS A 2014 GMC SIERRA. THE CONTACT STATED THAT THE HEADLIGHTS WERE DIM AND PROVIDED POOR VISIBILITY. THE FAILURE WAS WORSE IN RAINY CONDITIONS. THE VEHICLE WAS TAKEN TO A LOCAL DEALER WHO STATED THAT THE LIGHTS LACKED VOLUME; HOWEVER, THEY DID NOT OFFER ANY REMEDY. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 23,000. UPDATED 02/12/16*LJ THE CONSUMER STATED THE TAIL GATE ALLOWED DIRT TO ENTER INSIDE THE TRUCK. UPDATED 03/03/16

#5 CYLINDER ROCKER ARM BROKE TOOK TO A DEALERSHIP IN MICHIGAN TO GET REPAIRED. PROBLEMS WITH ENGINE RUNNING, BEFORE ALL THIS HAPPENED I WAS GETTING 20/22 MPG ON THE HIGHWAY WHICH IS WHAT I TRAVEL MOSTLY, NOW SINCE THIS HAPPEN I ONLY GETTING 16/18 MPG ON THE HIGHWAY. MY DEALERSHIP IN MILWAUKEE WORKED WITH AN ENGINEER FROM GM AND THEY CLAIM EVERYTHING UP TO SPEC AND WON'T DO ANYMORE ON THE VEHICLE BUT YET SOMETHING HAS HAPPENED THAT I HAVE LOST ABOUT 4/6 MPG HIGHWAY OR $20 PER TANK WHICH WITH MY TRAVELING IS A LOT OF MONEY $400 MONTH. I AM VERY DISSATISFIED WITH GM AND THIS VEHICLE RIGHT NOW WHEN YOU PAY $50,000 + FOR A VEHICLE YOU DON'T EXPECT TO HAVE PROBLEMS WITHIN THE FIRST MONTH OF PURCHASE (BRAND NEW) AND THEN FOR GM NOT TO FIND OUT WHY THE DROP IN MILEAGE IS UNACCEPTABLE. *TR

MY SON AND I WERE DRIVING MY GMC SIERRA 2014 TO HIS FRIENDS HOUSE BEFORE WE CRASHED. MY SON WAS DRIVING AND HAS HIS LEARNER'S PERMIT, HOWEVER, HAD BEEN DRIVING FOR 4 MONTHS. AT A FORK IN THE ROAD I TOLD MY SON QUICKLY TO MAKE A RIGHT RATHER THAN LEFT AND WE CRASHED INTO AN IMPROPERLY GRATED WALL OF DIRT CAUSING THE TRUCK TO GO FROM 40 MPH TO 0 WITH MY SON HAVING HIS SEATBELT ON, BUT I DID NOT. NEITHER AIRBAGS DEPLOYED AND BOTH OF US SUSTAINED SERIOUS INJURIES. MY SON BROKE HIS NOSE AND I AM SUFFERING FROM A BROKEN NOSE, CONCUSSION AND A BURST VERTEBRAE. NEITHER AIRBAGS DEPLOYED WHICH COULD'VE MADE A HUGE DIFFERENCE ON OUR INJURIES. *TR

I PURCHASE THIS VEHICLE NOV. 2013, AND EVER SINCE I NOTICE THAT THE HEADLIGHT ON THIS VEHICLE DO NOT LIGHT THE ROAD PROPERLY, WHETHER YOU HAVE THEM IN LOW OR HIGH BEAM. THE DISTANCE OF THE LOW AND HIGH BEAM APPEAR TO BE THE SAME (AT TIMES IT SEEMS THE HIGHS) ARE AIMING SKYWARD. NOT TO LONG AGO I ALMOST RAN OVER A WOMAN AND A CHILD WHO WERE CROSSING A STREET OVER TO MY LEFT WHEN I WAS ATTEMPTING TO MAKE A LEFT TURN (THIS WAS A DARK AREA). LUCKILY I WAS GOING SLOW WHEN I WAS MAKING THE TURN AND WAS ABLE TO SEE THEM WHEN THE HEADLIGHTS HIT THEM AND CAME INTO VIEW. BY THIS STATEMENT I AM TRYING TO POINT OUT THAT THERE NO LIGHTING TO EITHER SIDE OF THE VEHICLE, I AM SURE (POSITIVE) THAT IF I WOULD HAVE BEEN MAKING A RIGHT TURN AN ACCIDENT WOULD HAVE HAPPEN. ARE THERE ANY RECALLS REGARDING THIS PROBLEM? IF NOT, I THINK THERE SHOULD ONE. BECAUSE IF SOMETHING LIKE THIS EXAMPLE I AM SUBMITTING TO YOU EVER HAPPENS, THE DRIVER WILL HELD RESPONSIBLE. AN IN MY CASE IT WILL BE BLAMED DUE TO MY AGE. *TR

THE HEADLIGHTS ON THIS TRUCK PROVIDE INADEQUATE LIGHTING, INCLUDING BOTH LOW BEAMS AND HIGH BEAMS. ANY NIGHT DRIVING IS DIFFICULT DUE TO LIMITED VISIBILITY, THERE SIMPLY IS NOT ENOUGH ILLUMINATION TO SEE. CAN BE VERY DANGEROUS - ESPECIALLY AT SPEEDS ABOVE 35 MPH OR DURING PRECIPITATION. THE HEADLIGHT HAS A SEVERE DESIGN FLAW WITH GMS APPROACH AT A SHUTTER SYSTEM. THIS TYPE OF DESIGN DOES NOT LEAVE ANY OPTIONS FOR SIMPLY CHANGING THE TYPE OF BULB - THE DESIGN IS ACTUALLY AT FAULT FOR THE POOR VISIBILITY. THE VISIBILITY PROBLEMS SIMPLY CANNOT BE FIXED WITH A DIFFERENT BULB TYPE DUE TO THE SHUTTER DESIGN TYPE. MANY COMPLAINTS ARE BEING REGISTERED ONLINE RELATED TO THE VISIBILITY PROBLEM. THESE TRUCKS ARE NOT SAFE TO DRIVE AT NIGHT. IF THERE IS A STANDARD FOR MINIMUM HEADLIGHT ILLUMINATION FOR NIGHT TIME DRIVING, THIS MODEL HEADLIGHT NEEDS TO BE REVIEWED IF IT IS MEETING THE MINIMUM STANDARD. NOT SAFE, A DEFINITE PROBLEM THAT NEEDS ATTENTION. *TR

REGARDING 2014 GMC SIERRA 6 CYLINDER FULL SIZE PICKUP. VEHICLE VIBRATES AS IF RUNNING OVER RUMBLE STRIPS AT APX 1500 RPM. LOCAL GM SERVICE CENTER AND GM CORPORATE REPRESENTATIVE STATED ABOVE IS NORMAL VEHICLE OPERATION. LOCAL GM SERVICE CENTER CORRECTLY SUGGESTED THAT TRUCK BE DRIVEN FASTER OR SLOWER TO PREVENT VIBRATION OR THAT VEHICLE BE DRIVEN IN 5TH GEAR RATHER THAN OVERDRIVE 6TH GEAR TO PREVENT VIBRATION. IF VEHICLE IS NOR DRIVEN FASTER OR SLOWER TO GET OUT OF VIBRATION RANGE, THE TRUCK WILL VIBRATE ENDLESSLY. 2014 GMC SIERRA IS AN UNSAFE VEHICLE. NEEDING TO SPEED UP OR SLOW DOWN TO PREVENT VIBRATION SIGNIFICANTLY INCREASES RISK FOR MVA. NEEDING TO DRIVE IN 5TH GEAR RATHER THAN 6TH GEAR REDUCES GAS MILEAGE AS REPORTED TO NHSTA. LOCAL MECHANICS HAVE COMMENTED THAT THE ABOVE VIBRATION COMPLAINT IS COMMON TO 2014 6 CYLINDER GMC/CHEVY FULL SIZE PICKUP TRUCKS AND THAT THE VIBRATION MAY BE SECONDARY TO CYLINDER DEACTIVATION AND CHASSIS RIGIDITY. IT CERTAINLY WOUND BE A SHAME FOR A COLLISION TO OCCUR OR FOR A PEDESTRIAN TO GET RUN OVER BY A DRIVER OF A 2014 GMC/CHEVY FULL SIZE PICKUP WHO HAD TO SPEED UP OR SLOW DOWN TO REDUCE EXCESSIVE VIBRATION AT APX 1500 RPM

THE CENTER CONSOLE WITH SHAKE EXCESSIVELY IF GOING 70-80 MPH. IT WILL ALSO SHAKE BAD GOING DOWN A MAIN ROAD I DRIVE ON DAILY DOING 45-55 MPH. THE TRUCK HAS HAD THE TIRES REBALANCED TWICE NOW WITH NO SOLUTION FOUND. THE TRUCK HAS BEEN IN THE SHOP OVER 20 DAYS ALL TOGETHER FOR OTHER VIBRATION ISSUES AS WELL. *TR
