What 131 owners told NHTSA about the 2014 GMC Sierra 2500 Hd

Backing out of driveway, suddenly lost the transmission. I was stranded at about a 45-degree angle into the traffic lane. I had no gear position indication (an automatic) and couldn't move the truck under it's own power. Shut it off and restarted twice before I got it into "limp-mode" and, while abrupt and harsh, managed to get back into my driveway. Found fault code U0101, Lost Communication with TCM (Transmission Control Module). Had never heard that this has become a common problem. Discovered quickly GM has no parts available, no repairs available, and that it is happening to thousands of GM trucks from model years 2008 to 2015. The truck is useless without this module function. We use this truck to tow a 12000+ lb. travel trailer. I can't imagine how bad this could have been in freeway traffic with such a load. Have been told GM put the part on a national back order in October of 2022, with no estimate of availability. It's now late August of 2023 and still nothing available. Has me concerned that one of these vehicles could stall right in front of me in traffic! I can't afford to replace this vehicle, can't move it, and am relegated to going to work on a motorcycle- in traffic with other GM trucks just waiting to experience this failure. And winter is coming...

I WENT TO OPEN THE ELECTRIC REAR SLIDING WINDOW, AND IT STARTED TO OPEN, THEN IT STOPPED HALFWAY OPEN, WITH A BLACK CABLE HANGING DOWN. MY TRUCK ONLY HAS ABOUT 23,000 MILES ON IT, AND HAVE ONLY OPEN IT LESS THAN 12 TIMES. IT STILL DOESN'T WORK. I TRIED TO COMPLAIN TO GENERAL MOTORS CORP. CUSTOMER SERVICE, WITH THEM TELLING ME THAT IT WOULD COST ME $542.65 WITH GM ASSISTANCE. THIS IS REDICULOUS. IT MUST HAVE BEEN INSTALLED WRONG, OR IT WAS DEFECTIVE. I WAS STOPPED AT MY HOUSE WHEN THIS HAPPENED. I'VE MADE SEVERAL CALLS TO THE CUSTOMER SERVICE, SPEAKING TO SEVERAL REPRESENTATIVES, AND I KEEP GETTING THE SAME ANSWER, THATI WILL NEED TO PAY TO HAVE THE WHOLE WINDOW REPLACED (NOT FIXED). I WOULD LIKE TO KNOW IF THERE ARE OTHER COMPLAINTS ABOUT THIS SAME ISSUE FROM OTHER CUSTOMERS. THE DEALER THAT QUOTED ME THE COST WAS SANBORN CHEVROLET, IN LODI, CA.

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 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 SAYS IS 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. THE NEED FROM A NEW HEADLIGHT WILL SOLVE THE PROBLEM. 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.

HEADLIGHTS ON THIS VEHICLE ARE TERRIBLE. VERY POOR ILLUMINATION FOR NIGHT DRIVING.THERE SHOULD BE A SAFETY RECALL FOR THESE HEADLIGHTS, PICKUP IS DANGEROUS TO DRIVE AT NIGHT.HEADLIGHTS LIGHT UP ROAD ABOUT 50-60 FEET AND OFFER VERY POOR SIDE VISION.HIGH BEAMS ARE USELESS AND SHINE UP IN THE TREES AND NOT ON THE ROAD.VEHICLE HAS PROJECTORS WITH ONLY A FLAPPER TO CHANGE HIGH/LOW BEAM.IHAVE BEEN DRIVING FOR 40 YEARS AND HAVE NEVER DRIVEN A VEHICLE WITH THIS POOR HEADLIGHT DESIGN. I CANNOT BELIEVE HEADLIGHT PASSED PHOTOMETRIC DESIGN CERTIFICATION (MAYBE THEY DID NOT) I HAVE COMPLAINED TO GMC BUT THEY SAY HEADLIGHTS ARE WORKING AS DESIGNED. HEADLIGHT ASSEMBLIES WERE REPLACED ONCE AND ADJUSTED SEVERAL TIMES BY DEALER.STILL NO REMEDY TO THE PROBLEM. *TR
