BOTH LED TAIL LIGHTS STARTED FLICKERING AND FAILED WITHIN A MONTH OF EACH OTHER. THE MECHANIC SAID THIS WAS A KNOWN ISSUE WITH THESE LIGHTS AND THAT THE CIRCUIT BOARD FAILED.

THE VEHICLE WAS PURCHASED IN DECEMBER USED. THE VEHICLE NOW HAS 62,000 MILES. VEHICLE WAS PARKED OVERNIGHT AFTER WORKING FINE THE DAY BEFORE. WENT TO USE AIR CONDITIONING AND IT WOULD ONLY BLOW HOT AIR. AFTER CHECKING ONLINE, AND WITH EXPERIENCES FROM OTHER OWNERS, THE AIR CONDITIONING FAILURES APPEARS TO BE A VERY COSTLY COMMON ISSUE BUT THERE ARE NO RECALLS FOR THE DEFECTIVE PARTS. THE VEHICLE IS STILL IN FOR REPAIRS AT THIS TIME. ALTHOUGH THIS ISSUE WAS NOT SPECIFICALLY SAFETY RELATED IN MY SITUATION, THE POTENTIAL FOR SAFETY CONCERNS EXIST. HAD THE AC FAILED WHILE THE VEHICLE WAS RUNNING WITH CHILDREN OR ANIMALS INSIDE COULD BE FATAL.

INTERNAL CIRCUITRY OF PASSENGER TAIL LIGHT CRACKED IN MULTIPLE LOCATIONS CAUSING THE LED'S THAT PROVIDE RUNNING AND STOP FUNCTIONS OF THE LIGHT TO FAIL. THE CAR WAS NOT WRECKED OR DAMAGED IN ANY WAY. APPEARS AS IF METAL FATIGUE FROM BUMPY ROADS PERHAPS CAUSES THE CIRCUITRY TO FAIL AT AT LEAST 2 WEAK POINTS IN THE METAL CIRCUIT. THE PROBLEM WAS POINTED OUT BY A TRAILING POLICEMAN WHILE STOPPED AT A RED LIGHT, HE KINDLY NOTIFIED ME THAT THE ENTIRE LIGHT WAS OUT.

TL* THE CONTACT OWNS A 2016 GMC YUKON. THE CONTACT STATED THAT THE PASSENGER SIDE BRAKE LIGHT FAILED TO ILLUMINATE WHEN THE BRAKE PEDAL WAS DEPRESSED. THE VEHICLE WAS TAKEN TO GREINER BUICK GMC (14555 CIVIC DR, VICTORVILLE, CA 92394, (760) 245-3451) WHERE THE CONTACT WAS INFORMED THAT THE TAIL AND BRAKE LIGHT ASSEMBLIES NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 81,000.

MY WIFE WAS DRIVING DOWN A MAJOR ROAD AND A PERSON PULLED NEXT TO HER AT A STOP TO TELL HER THAT HER BRAKE LIGHTS WERE WORKING ONLY PART OF THE TIME. GM HAD JUST SERVICED MY VEHICLE AND DIDN'T CATCH IT, AND UPON RESEARCHING THE ISSUE, IT IS A KNOWN FAULTY DESIGN OF THE TAIL LIGHT ASSEMBLY. THE LED BRAKE LIGHT STARTS INTERMITTENTLY FAILING AT THE 2 YEAR POINT, LEADING TO DRIVERS FOLLOWING DRIVERS TO NOT KNOW THAT THE LEADING VEHICLE IS STOPPING. THIS IS A COMMON ISSUE AND THE ONLY RESPONSE FROM GM IS TO MAKE THE CUSTOMER BUY A NEW $700 BRAKE LIGHT ASSEMBLY. THE ISSUE IS SO COMMON THAT MULTIPLE COMPANIES HAVE STARTED BRAKE LIGHT REPAIR SERVICES AND MULTIPLE YOUTUBE VIDEOS EXIST TO WALK INDIVIDUALS THROUGH THE PROCESS OF REPAIRING THEIR OWN BRAKE LIGHTS. THE COST OF THE REPAIR IS SO STEEP THAT I HESITATE TO GET THE PROBLEM FIXED, AND THOUGH GM REPORTEDLY HAS DEVELOPED A REPLACEMENT LIGHT ASSEMBLY THAT CORRECTS THE FAULT, THEY ARE NOT TAKING RESPONSIBILITY FOR THE DEFECTIVE BRAKE LIGHT ASSEMBLE THAT THESE VEHICLES COME OFF THE ASSEMBLY LINE WITH. THE MAJOR DANGER IS THAT WE DRIVE FROM THE FRONT OF THE VEHICLE AND LIKELY DO NOT KNOW OUR BRAKE LIGHTS ARE INTERMITTENTLY FAILING--SINCE GM CANNOT EVEN CATCH THIS WHEN THEY DO SERVICE ON VEHICLES (MINE HAD BEEN IN THE SHOP FOR AN OIL CHANGE A FEW WEEKS BEFORE THE BRAKE ISSUE), THEN THEY ARE LEAVING A LOT OF CUSTOMERS DRIVING WITHOUT BRAKE LIGHTS TO AVOID THE COST OF THE REPAIR EVEN THOUGH THEY APPROVED A FAULTY DESIGN.

CAR ENGINE SHUT OFF WITH NO WARNING, I STARTED THE CAR, DROVE ABOUT 50 YARDS TO A STOP SIGN, STOPPED, STARTED TO PULL AWAY AND THE ENGINE COMPLETELY DIED. NO WARNING LIGHTS. I WAS HALFWAY INTO THE STREET. I PUT THE CAR INTO PARK AND WAS ABLE TO START IT AGAIN. THE CAR HAS ABOUT 37,000 MILES AND WAS SERVICED BY THE DEALER 11 DAYS PRIOR (ROUTINE SERVICE).

RUNNING BOARDS FAILING TO WORK PROPERLY ALL THE TIME. SOMETIMES WILL START TO GO DOWN BUT RETURN UP WHEN OPENING DOOR. WILL ALSO FAIL TO GO UP AFTER CLOSING DOOR AND REMAIN DOWN. MIDDLE ROW DVD SCREEN IS BLACK AND NOT WORKING. REAR BRAKE LIGHTS WORKING OFF AND ON. HORRIBLE LOUD SQUEALING SOUND UNDER THE HOOD. THE VEHICLE WILL ALSO BEGIN TO SHAKE RANDOMLY AND FEELS JUMPY AT TIMES.

NHTSA ODI 11258057

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. WHILE DRIVING VARIOUS SPEEDS OR WHILE THE VEHICLE WAS STATIONARY, THE REAR BRAKE LIGHTS EITHER INTERMITTENTLY ILLUMINATED OR DID NOT ILLUMINATE AT ALL. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE THE CONTACT WAS INFORMED THAT THE TAIL LIGHT ASSEMBLY BOARD WAS LOOSE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE DEALER WAS NOT CONTACTED.

TRANSMISSION HAS NOT SHIFTED CORRECTLY. SHUDDERING OCCURS OR SHIFTS ARE NOT SMOOTH

OVER THE LAST SEVERAL YEARS, WE HAVE BEEN HEARING THIS CLICKING SOUND IN OUR 2016 GMC YUKON XL. ADDITIONALLY, WE HAD EXPERIENCED OCCASIONAL TIMES WHERE THE VEHICLES BRAKES WOULD NOT FUNCTION PROPERLY MOSTLY IN SLOWER SPEED SITUATIONS. IN THE LAST SEVERAL WEEKS, THE SHORT RANGE BRAKING WAS HINDERED AGAIN AS THE BREAK WOULD 'STICK' AND NOT SLOW THE CAR. SEVERAL CLOSE INSTANCES OF HITTING EITHER ANOTHER CAR OR FAMILY MEMBER. I THEN LOOKED UP ON NHTSA IF ANY RECALLS, AND I NOTICED A RECALL WHICH DESCRIBED EXACTLY WHAT WE HAD BEEN EXPERIENCING. WE TOOK THE VEHICLE INTO THE DEALERSHIP YESTERDAY AND THEY TOLD MY WIFE IT WAS FIXED AND SENT HER ON HER WAY TO PICK UP MY 5 CHILDREN FROM SCHOOL. A FEW HOURS LATER, THE CAR JUST WOULDN'T BREAK AND MY WIFE CALLED ME TO ACTUALLY GO TO THE LOCATION ON MY CHILD'S PRACTICE SO I COULD DRIVE IT HOME AS SHE DIDN'T TRUST THE VEHICLE ANY LONGER. I TOOK THE VEHICLE BACK TO THE DEALER THE NEXT DAY. UPON THEIR INSPECTION, THEY SAID THE VACUUM PUMP WAS FAULTY AND WOULD COST $500 TO FIX. THEN I STARTED TO INVESTIGATE FURTHER, AND TO MY SURPRISE, THERE APPEARS TO BE A LONG STANDING ISSUE WITH 2014-16 GM VEHICLES THAT HAVE HAD FAULTY VACUUM PUMPS. HOWEVER, THESE HAVEN'T BEEN RECALLED YET. THE REVIEW ALSO LED ME TO THE CONCLUSION THAT THE CLICKING SOUND WE WOULD HEAR APPEARS TO BE RELATED TO THIS FAULTY PART. UNFORTUNATELY FOR ME, MY MILES ARE BEYOND THE WARRANTY PERIOD BUT THIS HAS BEEN A PERSISTENT ISSUE FOR A LONG TIME. BASICALLY, IT FEELS AS IF MY FAMILY'S SAFETY WAS SECONDARY WHILE THIS KNOWN ISSUE WITH THE VACUUM PUMP REMAINED 'SILENT'. WE BOUGHT THIS VEHICLE FOR THE SAFETY, DEPENDABILITY, AND PLANNED TO USE IT UP TO 200,000+ MILES. I AM DISAPPOINTED THAT A SAFETY ISSUE LIKE THE BRAKES WOULD EFFECTIVELY BE UNDISCLOSED TO ME AS A CAR OWNER. I AM HOPEFUL GM WILL DO ALL THAT IS NECESSARY TO RECTIFY OUR DISCOMFORT AND LACK OF TRUST.

LEFT REAR LED BRAKE/TAIL LIGHT WENT OUT AT APPROXIMATELY 43,000 MILES. IN DOING RESEARCH THIS IS A COMMON PROBLEM IN GMC YUKON. IT SEEMS TO BE JUST AFTER WARRANTY EXPIRES AS MINE DID. THE COST TO REPLACE IS ANYWHERE AROUND $800.00. I HAVE NO CHOICE BUT TO GET IT REPLACED AS IT IS A SAFETY ISSUE. RESEARCH ALSO SAYS THESE LED'S SHOULD BE LASTING MUCH LONGER THAN THEY ARE ON THIS MAKE AND MODEL. I FEEL WITH THE NUMBERS SO HIGH GMC REALLY NEEDS TO LOOK INTO A RECALL AND GET THIS PROBLEM FIXED OR HELP COMPENSATE SOME OF THE COST. ALSO, THIS PART IS NOT READILY AVAILABLE SO WE GO WEEKS WITH NO BRAKE OR TAIL LIGHT UNTIL IT CAN BE REPAIRED. THIS IS SO NOT SAFE!!

NHTSA ODI 11256174

DRIVERS BRAKE LIGHT SHORTS OUT AND STOPS WORKING.

NHTSA ODI 11255558

LED BRAKE LIGHTS FAILED AND CANNOT BE REPAIRED. I CANNOT REPLACE BULBS EITHER. GMC WANTS $600+ TO REPLACE THE LIGHT WITH ONE THAT HAS RISK OF FAILURE, SAME AS THE ORIGINAL! NO GUARANTEE!

NHTSA ODI 11255611

TL* THE CONTACT OWNS A 2016 GMC YUKON. AFTER STARTING THE ENGINE, THE VEHICLE WOULD NOT OPERATE WHILE IN THE DRIVE OR REVERSE POSITIONS. THE VEHICLE WAS TOWED TO SHEEHAN BUICK GMC (2800 SEVERAL HWY, POMPANO BEACH, FL 33064) WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION WAS FAULTY AND NEEDED TO BE REPLACED. THE TRANSMISSION WAS REPLACED AND THE FAILURE WAS REMEDIED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 144,000. THE VIN WAS INVALID.

I HAD THE RECALL (N192268490) APPLIED TO MY YUKON ON 12 SEP. I ONLY EXPERIENCED THE PROBLEM DESCRIBED IN THE RECALL 2X PRIOR TO THE RECALL. SINCE THE RECALL I HAVE HAD MULTIPLE INCIDENTS MUCH WORSE THAN THAN THE ORIGINAL PROBLEM. TONIGHT THE BRAKES WERE SO BAD I OVER SHOT MY PARKING SPOT AND DROVE INTO SOME BUSHES. IF A HARD STRUCTURE WAS THERE I WOULD HAVE DAMAGED THE CAR. THIS PROBLEM IS REPEATABLE. NO WARNING LIGHTS COME ON BUT THE "GRADE BREAKING ON" LIGHT WILL COME ON. THE BREAK PEDAL WAS VERY SOFT AND SHUTTERED. I EMPHASIZE THIS IS NEW SINCE THE RECALL WAS IMPLEMENTED.

NHTSA ODI 11256030

A CAR BRAKED IN FRONT OF ME GOING AROUND 40 MILES PER HOUR. I WAS UNABLE TO STOP IN TIME AND REARENDED THEM. THIS CAR IS PART OF THE GM RECALL FOR BRAKES

NHTSA ODI 11254852

THE RIGHT TAIL LIGHT AND BRAKE LIGHT FAILED AT ONLY 44,000 MILES. FAILS TO WORK IN ALL PHASES OF OPERATION.

NHTSA ODI 11254356

DRIVERS SIDE TAIL LIGHT/BRAKE STARTED FAILING, ONLY WORKING INTERMITTENTLY WHILE DRIVING AND WHILE STOPPED. NOW ONLY A SMALL OUTER CORNER OF THE THE LIGHT IS WORKING.

NHTSA ODI 11254155

THE LED BRAKE LIGHTS FAIL INTERMITTENTLY AND THEN COMPLETELY DUE TO A DESIGN FLAW OF WEAK CIRCUITRY. THE LED CIRCUIT BREAKS FROM FATIGUE IN THE BRAKE LIGHT HOUSING. THERE IS NO DASH NOTIFICATION TO TELL YOU WHEN A BRAKE LIGHT HAS FAILED. GM REPLACEMENT BRAKE LIGHTS COST $650 EACH BUT THEY HAVE THE SAME DESIGN FLAW. PICTURES ATTACHED.

NHTSA ODI 11253562

VEHICLE SHAKES/VIBRATES ABOVE 35 MPH. WHEN VEHICLE ACCELERATES ABOVE 35 MPH THE THE STEERING WILL VIBRATE WITH A FEELING THAT THE SUSPENSION IS SHIMMYING/SHUDDERING RAPIDLY. THIS IS ESPECIALLY BAD ON AN INCLINE FROM A STOPPED POSITION. AS THE VEHICLE ACCELERATES UP THE INCLINE, WHEN APPROXIMATELY 35 MPH IS ATTAINED, THE ENTIRE VEHICLE WILL STEADILY SHUDDER/VIBRATE. TRAVELING AT HIGHWAY SPEEDS THE VEHICLE WILL RANDOMLY VIBRATE IN THE FRONT END AND IN THE STEERING WHEEL. THIS OCCURS WITH BRAND NEW TIRES THAT HAVE BEEN BALANCED AND RE-BALANCED TO CONFIRM IT IS NOT TIRE RELATED.

NHTSA ODI 11253701

BOTH OF THE TAILLIGHTS WORK INTERMITTENTLY. I HAVE TAKEN IT IN TO THE GMC DEALER ONLY TO BE TOLD IT WILL BE 2000.00 TO REPLACE THEM BOTH. THIS IS A FACTORY PROBLEM. SOMETIMES ONE WORKS, SOMETIMES THEY BOTH WORK AND SOMETIMES NEITHER WORK, IN MOTION, STATIONARY, ALL STREETS AND AT ANY TIME.

NHTSA ODI 11253481

THE TRANSMISSION WENT OUT, THE ENGINE IS MAKING A NOISE AND A SERVICE CENTER SAID LOTS OF GM'S VEHICLES ARE HAVING THE SAME PROBLEM THE POWER STEERING SYSTEM ALSO STOP WORKING AND I HAVE TO REPLACE IT

NHTSA ODI 11252626

DRIVER SIDE REAR BRAKE AND TAIL LIGHT AND TURN SIGNAL WORKS INTERMITTENTLY. SOMETIMES IT WORKS FINE, SOME TIMES IT FLICKERS, AND SOMETIMES IT IT TOTALLY OUT. THIS ISSUE HAPPENS RANDOMLY. I HAVE SEEN IT WHILE PARKED, AND WHILE GOING DOWN THE ROAD

NHTSA ODI 11252635

BRAKE LIGHTS FAULTY. HAVE HAD BOTH PASSENGER AND DRIVER'S SIDE REPLACED. DRIVERS SIDE IS NOW SHORTING OUT AGAIN. TONS OF OWNERS OF THE YUKON LINE HAVE HAD THE EXACT SAME PROBLEM WITH FAULTY TAIL LIGHTS. LAW ENFORCEMENT THINKS IT IS A MAJOR SAFETY ISSUE WHICH IT IS! THESE TAIL LIGHTS WORK INTERMITTENTLY OR NOT AT ALL!
