WHILE THANKFULLY DRIVING IN THE SLOW LANE ON THE INTERSTATE IN ST. LOUIS MY STABILITY LIGHT CAME ON THE TRUCK THEN SLOWED DOWN ON ITS OWN THEN WENT INTO FOUR-WHEEL-DRIVE THEN REVVED UP TO 6000 RPMS THEN EVERY SERVICE LIGHT CAME ON ON THE DASH WHEN PULLING TO THE SIDE OF THE ROAD THE CAR THEN WOULD NOT DRIVE FORWARD IT STAYED IN NEUTRAL REGARDLESS OF GEARSHIFTING IT THEN BEGAN TO CYCLE THROUGH ALL OF THE SERVICE REQUEST FOR THE VEHICLE. AFTER HAVING TO HAVE THE VEHICLE TOWED TO THE NEAREST DEALERSHIP WHICH WAS THREE HOURS AWAY FROM MY HOUSE THEY INFORMED ME THE FOLLOWING MORNING THE POWER STEERING CONTROL GEARBOX HAD WENT OUT AND FRIED ALL THE ELECTRICAL'S INSIDE THE VEHICLE. THE VEHICLE HAS LESS THAN 39,000 MILES AFTER CONTACTING GMC THEY TOLD ME THERE WAS NOTHING THEY COULD DO THAT THERE WAS NOTHING ON A RECALL LIST FOR MY VEHICLES VIN NUMBER. AFTER DOING SOME RESEARCH I SAW THAT THERE WAS A RECALL FOR A VERY SIMILAR SITUATION IN 2018 IN SEPTEMBER. I HAVE VIDEOS OF THE VEHICLE COMPUTER SYSTEM MALFUNCTIONING IF REQUESTED. I JUST WANTED TO DOCUMENT AND FILE A COMPLAINT SO THIS DIDN'T HAPPEN TO SOMEONE ELSE AND CAUSE A SERIOUS WRECK , SINCE GMC HAS FAILED TO RECOGNIZE THIS SERIOUS OF AN ISSUE.

PASSENGER SIDE TAIL LIGHT STOPS WORKING OCCASIONALLY. THIS AFFECT'S THE BRAKE LIGHT AND NIGHT DRIVING. IT HAS STOPPED WORKING UP TO A WEEK AT A TIME, BUT THEN STARTS WORKING AGAIN. IT MIGHT BE WEATHER RELATED.

TAIL LIGHTS WORK INCONSISTENTLY, DEALERSHIP TELLS ME IT'S COMMON PROBLEM WITH MY YEAR AND MODEL.

NHTSA ODI 11289565

REAR PASSENGER BRAKE LIGHT IS WORKING INTERMITTENTLY. PURCHASED EXTENDED WARRANTY, BUT IT IS NOT COVERING COST TO REPLACE WHICH DEALER SAYS WILL BE OVER $700. WAS TOLD THAT GMC KNOWS THESE LIGHTS ARE NOT LASTING AS LONG, SO THEY EXTENDED THE WARRANTY OF THE LIGHTS, BUT I AM STILL OUT DUE TO MILES ON MY CAR. THE PURCHASED EXTENDED WARRANTY GOES TO 125K MILES, BUT THEY WILL NOT COVER.

BRAKE LIGHT GOES IN AND OUT AND DOESN'T WORK ALL THE TIME. ACCORDING TO WHAT I'M READING IS A VERY COMMON ISSUE AND NEEDS TO BE FIXED. THERE IS NO FIX EXCEPT BUYING A BRAND NEW ONE AND THAT DOESN'T SEEM RIGHT. SEEMS LIKE A POOR DESIGN AND NOT TO MENTION I CAN GET A TICKET FOR THIS. AND MOST IMPORTANT...I HAVE A FAMILY WITH TWO SMALL KIDS AND THIS IS A SAFETY HAZARD IF MY BRAKE LIGHTS DO NOT WORK!

CAR WAS PARKED IN FRONT OF OUR HOUSE AND COMBUSTED IN THE MIDDLE OF THE NIGHT WHILE WE WERE SLEEPING. CAR WAS EXPLODING AND ENGULFED IN FLAMES...COMPLETELY DESTROYED VIA FIRE AND THE WORST DAMAGE WAS IN THE ENGINE COMPARTMENT. CAUSE OF THE FIRE IS UNKNOWN ALTHOUGH BASED ON RESEARCH SOUNDS LIKE NHTSA CAMPAIGN #14V007000 OR 14V152000. FIRE DEPARTMENT EXTINGUISHED THE FIRE AND POLICE WERE ON THE SCENE.

REAR PASSENGER TAIL LIGHT OUT AND PASSENGER WINDOW ONLY GOES HALF WAY DOWN.

NHTSA ODI 11282983

REAR PASSENGER TAIL LIGHT NEEDS TO BE REPLACED AT A RIDICULOUS COST. EXTREMELY POOR ENGINEERING DESIGN. THAT IS IF IT WASN'T INTENTIONALLY DESIGNED TO FAIL. ON THE LOW END $5-600 TO REPLACE A TAIL LIGHT??? WHAT A JOKE. SAD THING IS I'M LUCKY, MANY MANY PEOPLE HAVE HAD MORE THAN ONE LIGHT ASSEMBLY GO OUT. I'VE BOUGHT GM FOR MY LAST 3 VEHICLES (ENVOY, TAHOE, YUKON) THIS WILL LIKELY BE THE LAST TIME I EVER BUY GM.

TL* THE CONTACT OWNS A 2015 GMC YUKON XL. WHILE DRIVING AND ATTEMPTING TO MAKE A TURN AT APPROXIMATELY 10 MPH, THE VEHICLE SHUT OFF AND LOST POWER WITHOUT WARNING. THE VEHICLE RESTARTED AFTER APPROXIMATELY 30 MINUTES AND 'PLEASE OPEN AND CLOSE DRIVER'S SIDE WINDOW' APPEARED. THE DEALER AND MANUFACTURER WERE NOT CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 97,000.

NHTSA ODI 11282717

BRAKE LIGHTS WORK SPORADICALLY, UNTIL THE PASSENGER REAR FINALLY STOPPED WORKING ALL TOGETHER. CONTACTED THE DEALERSHIP AND WAS TOLD THIS WAS A VERY COMMON PROBLEM, THAT THEY REPLACE SEVERAL A WEEK, AND MY WARRANTY WOULD NOT COVER IT. GOT A ESTIMATE OF OVER $1600 TO REPAIR IT. WAS PULLED OVER ON SEVERAL OCCASIONS EACH TIME WAS TOLD IT WAS EITHER THE LEFT OR RIGHT NOT WORKING. THEN MIRACULOUSLY BOTH WOULD BE WORKING. IF THIS IS SUCH A COMMON PROBLEM LIKE THE DEALERSHIP STATED, THEN WHY HASN'T GM RECALLED OR DISCONTINUED USING THEM? THIS IS A SERIOUS SAFETY ISSUE AND NOT AS SIMPLE AS REPLACING A BULB. WAY TO COSTLY TO JUST BRING IN FOR REPAIRS!

NHTSA ODI 11282360

THE TAIL LIGHTS KEEP GOING OUT EVEN AFTER HAVING THEM REPLACED AT THE DEALERSHIP. I HAVE BEEN STOPPED BY THE POLICE AND HAVE ACTUALLY HAD TO SHOW THE INVOICE WERE I HAVE HAD THE LIGHTS.

NHTSA ODI 11281971

MY TAIL LIGHTS GO OUT EVERY NOW AND THEN. MORE IN THE SUMMER THAN THE WINTER. THE BREAK LIGHTS AND TURN SIGNAL STILL WORK GREAT. I HAVE LOOKED ONLINE AND IT LOOKS LIKE A LOT OF PEOPLE ARE HAVING THE SAME ISSUE. ITS A SAFETY ISSUE HAVING TAIL LIGHTS ONE MINUTE AND THEN NOT HAVING TAIL LIGHTS. I ASKED GM MONTHS AGO TO DO A RECALL AND STILL HAVEN'T HEARD ANYTHING. THIS HAPPENS WHILE IT IS IN MOTION AND STATIONARY. WE SEEN ONLINE THAT ALL THE ISSUE IS, IS A PLACE THAT COMES LOOSE IN THE TAIL LIGHT AND IT ONLY NEEDS SOLDERED TOGETHER. WE TOOK THE TAIL LIGHTS OUT AND HAD A PROFESSIONAL TO SOLDER IT AND THEY STARTED WORKING PERFECTLY. THEY NOW ARE WORKING PART TIME AGAIN. FOR THIS TO HAPPEN TO MULTIPLE PEOPLE I FEEL LIKE IT IS AN ISSUE GM SHOULD FIX. IF IT WAS RARE I WOULD UNDERSTAND IF I HAD TO BUY NEW TAIL LIGHTS. BUT WITH MULTIPLE PEOPLE HAVING THIS ISSUE WILL NEW LIGHTS NOT DO THE SAME?

THE A/C HAS QUICK WORKING. WE TOOK IT IN TO GET FIXED, THEY COULD FIND NOTHING WRONG EXCEPT LOW ON FREON. REPLACED AND IT IS GONE (HAS DYE IN IT & NO DETECTION WHERE IT HAS GONE). I DIDN'T DRIVE THIS CAR FOR 6 MOS. BECAUSE OF THIS (TOO HOT). I CAN'T AFFORD TO FIX EVERYTHING THAT IS GOING WRONG ON THIS CAR. SAME DAY A/C WENT OUT, THE HEAT SYSTEM WENT OUT ON THE DRIVER'S SIDE SEAT. JUST BLOWS COLD AIR! THIS IS RIDICULOUS! THE SUSPENSION IS NOW SLAMMING HARD AND SUPER LOUD (ESPECIALLY WHEN IT IS COOL/COLD OUT). I AM GLAD THEY ARE FINALLY FIXING THE BRAKE ISSUE BUT REALLY? ALL THIS OTHER BS ON THIS EXPENSIVE CAR? THE DAY WE GOT BACK FROM SHOP FOR THE A/C, THE DRIVER SIDE BRAKE LIGHT WAS OUT. OMG!! TALK ABOUT EXPENSIVE TO REPAIR!! 650-800 FOR JUST THE LIGHT ASSEMBLY THROUGH GMC AND THAT IS RECONDITIONED PARTS! WHY WOULD WE PUT MORE CRAP PARTS IN? WAITED ANOTHER 2 MOS TO SAVE MONEY TO GO TO AN AFTERMARKET PERSON TO FIX THIS. JUST WAITING ON THE OTHER SIDE TO GO OUT! LIGHTS GO OUT ALL THE TIME, WHY WOULD YOU MAKE THEM WHERE THEY ARE NOT AFFORDABLE? WE BABY OUR CAR, PARK AWAY FROM EVERYONE AND YET IT IS FALLING APART DUE TO THE CRAPPY PRODUCTS THAT GM USED TO MANUFACTURE IT. ALL THESE PROBLEMS HAPPENED (EXCEPT THE BRAKING ISSUE AND THE SUSPENSION) WHEN I WENT TO START THE CAR AND I NOTICED IT. THE SUSPENSION IS WHEN I AM DRIVING AND THE ROAD CAN JUST HAVE A 'WAVE" IN IT. IF THERE IS ANY SORT OF BOUNCE, THIS CAR WILL BOTTOM OUT AND IS SUPER LOUD.THE AIR STARTED 3/28/19 AND ALL HAS FOLLOWED. WE BOUGHT IT USED WITH 74K-ISH ON IT. HAVE ONLY HAD IT SINCE LAST JULY, 2018

A FEW DAYS AGO I GOT OUT OF MY TRUCK TO RETRIEVE A PACKAGE LEFT AT MY GARAGE DOOR. I PUT MY VEHICLE IN PARK WALKED AROUND MY CAR DOOR WALKED BY THE FRONT OF MY TRUCK TO RETRIEVE THE PACKAGE AND ALL THE SUDDEN I WAS KNOCKED DOWN. I DID NOT REALIZE WHAT HAPPENED UNTIL I LOOKED UP AND SAW MY TRUCK DRIVING TOWARDS ME. I SCREAM FOR HELP AS I CRAWLED BACKWARDS TO SAFETY. A FEW MINUTES LATER I REALIZE THE TRUCK WAS NO LONGER MOVING AND BY THE GRACE OF GOD MY WHEELS WERE TURNED SLIGHTLY AND IT HAD STOPPED BECAUSE IT HIT THE SIDE OF MY HOUSE. IT TOOK A COUPLE OF DAYS FOR THE SHOCK TO WEAR OFF OF WHAT COULD HAVE HAPPENED TO ME OR MY KIDS IF THEY WERE PLAYING OUTSIDE. MY HUSBAND AND I SPOKE TO A COUPLE OF PEOPLE INCLUDING A CERTIFIED MECHANIC AND WE FOUND OUT THAT THIS HAS HAPPENED BEFORE ON THE 2015 YUKONS. I AM ATTACHING PICTURES OF WHAT WE FOUND FROM GMC ALONG WITH MY TRUCK.

TAIL LAMPS, TAIL LAMPS TAIL LAMPS! NON SERVICEABLE LED ILLUMINATION BULB CIRCUIT IS FAULTY LEADING TO INTERMITTENT OPERATION. HAVING PART TIME BRAKE LIGHT IS AGAINST THE LAW AND MORE IMPORTANT TO ME, LEAVES MY FAMILY IN AN UNSAFE SITUATION. WEB SEARCH LEADS TO MANY MOTORIST HAVING THE SAME PROBLEM AS I. AS A PAYING TAXPAYER WE SHOULD NOT BE SOLD FAULTY GOODS THAT MAY HAVE DIRE CONSEQUENCES.

MY VEHICLE HAS SUFFERED FROM POOR SLOW SPEED BRAKING SINCE IT WAS NEW. I WAS TOLD THIS IS JUST A CHARACTERISTIC OF THE VEHICLE. WHEN I POINTED OUT THIS PROBLEM AGAIN, I WAS TOLD THAT GM RECOMMENDS REPLACING THE VACUUM PUMP, BUT SINCE I WAS OUT OF WARRANTY, I WOULD HAVE TO PAY OUT OF POCKET. AFTER NUMEROUS ACCIDENTS AND COMPLAINTS TO THE NHTSA, GM ISSUE A RECALL. THE RECALL DID NOT CALL FOR REPLACING THE VACUUM PUMP AS GM HAD PREVIOUSLY REQUESTED, AND INSTEAD DID A SOFTWARE UPDATE. I JUST HAD THIS RECALL PERFORMED, AND THE BRAKES ARE NOW WORSE THAN EVER BEFORE. TODAY, I WAS PULLING INTO A CARWASH, AND WHEN I HIT THE BRAKES, THEY WERE HARD AS A ROCK AND WOULD NOT STOP MY VEHICLE. I ALMOST HIT THE VEHICLE IN FRONT OF ME. I HAD TO WARN THE PERSON AT THE CARWASH TO BE CAREFUL THAT THE BRAKES WERE NOT WORKING PROPERLY. AFTER HE MOVED MY VEHICLE, HE SAID THAT HE NEW WHAT I WAS TALKING ABOUT. THIS SITUATION CAN BE VERY DANGEROUS. IT MAY CAUSE YOU TO STRIKE THE VEHICLE IN FRONT OF YOU. IF THERE IS A PERSON BETWEEN YOU AND THE VEHICLE IN FRONT OF YOU, SUCH AS A CARWASH, THEY MAY BE CRUSHED BETWEEN THE TWO VEHICLES. THIS PROBLEM OCCURS ONLY AT LOW SPEED SUCH AS PARKING LOTS OR IN STOP AND GO TRAFFIC. THIS PROBLEM HAS BEEN OCCURING SINCE THE VEHICLE WAS NEW. IT IS NOW WORSE AFTER HAVING THE RECALL PERFORMED TO CORRECT THIS PROBLEM. THE MOST RECENT OCCURENCE WAS TODAY.

ANYTIME THE VEHICLE IS RUNNING THE FUMES FROM THE EXHAUST MAKE ME AND MY KIDS FEEL NAUSEOUS AND GIVING HEADACHES JUST FROM WALKING TO/AROUND THE TRUCK TO GET IN. WE ARE TAKING THIS TRUCK TO THE DEALER ON MONDAY. BEING THE 3RD DEALER WE HAVE TAKEN IT TO IN THE PAST YEAR. HAVE HAD MANY OTHER ISSUES OUT OF THIS VEHICLE AND JUST CANT SEEM TO GET THEM ALL FIXED. FOR SUCH A PRICEY VEHICLE YOU WOULDNT THINK THERE WOULD BE THIS MANY PROBLEMS. THE LIFT GATE IS POPPING NOT WANTING TO OPEN OR SHUTS ON YOU AS YOU WALK UNDER IT. THE WINDOW APPLIQUES ARE JUST SLOWLY FLYING OFF 1 BY 1. TRANSMISSION IS HARD SHIFTING IN LOW GEARS, DURING ACCELERATION AND DECELERATION. WE HAVE A HORRIBLE GRINDING/SQUEAKING NOISE IN THE FRONT THAT YOU CAN FEEL IN THE FLOOR BOARDS. THE BRAKES, WE HAD A MODULE REPLACED, BUT IT STILL FEELS AS IF WHEN PUSHING THE PEDAL IT LOOSES PRESSURE, CAUSING NEAR ACCIDENTS. THIS IS INSANE!!!!!! BOOUGHT THIS TRUCK JUST OVER A YEAR AGO AND HAVE HAD NOTHING BUT PROBLEMS. WASTE OF TIME AND MONEY!

NHTSA ODI 11279279

THE REAR LEFT TAIL LIGHT HAS GONE OUT, WHICH IS A COMMON FAILURE MODE OF THIS DESIGN. THE ENTIRE TAIL LIGHT MODULE MUST BE REPLACED, PUSHING $1000 FOR A BAD DESIGN. THIS NEEDS TO BE RECALLED AND REPLACED, AS IT IS EXTREMELY AFFORDABLE AND A SAFETY ISSUE THAT GMC WILL NOT ADDRESS.
