Defective wire harness between 2 body control modules, causing alarm to go off repeatedly "Service Trailer Brake System" and also "Stabilitrack" will come on randomly and lock my brakes up and all of the features in my dash. This has been very scary to drive and has brought the vehicle close to collision more than a handful of times now.
I keep getting a warning on my display on dash about my trailer brake system is not working. Also my temperature gauge stops working and I have to take off negative cable on battery to reset it. Temperature control sensor has been replaced but the problem still continues to happen.
Trailer service alert
My car is giving me all kinds of warnings, parking assist off, rear back up, trailer brake, the radio sounds go off, blinker sounds go off, while trying to park power steering locks up, it will die in the middle of a turn. It’s doing everything The 2015 recall was created for. I do not think my car was fixed during the recall period. It is very hazardous.
My vehicle Has a Service Trailer Brake System notification in my dash that dings as well. It does it on cold mornings with no trailer attached. I don’t trailer often.
Trailer assist error. Brakes not working. Ac compressors been replaced and the fan runs after the vehicles off and ac only blows warm air
Both tail lights work intermittently. Short in wiring ?
My "Service Trailer Brake System" messages comes on periodically for days at a time with and without my trailer. The loud chime rings consistently for the duration of the drive. It makes driving unbearable. When connecting my trailer to it, the brakes do not seem to function correctly when towing. This is very dangerous. I found out that a lot of my fellow GMC SUV drivers have the same problem.
The contact owns a 2015 GMC Yukon. The contact stated that while operating the vehicle, the power steering malfunctioned causing the steering wheel to become very difficult to turn in either direction. The contact indicated that recently when the failure occurred the vehicle also shut off nearly causing a crash. The vehicle was taken to the local dealer who diagnosed that the battery cables needed to be replaced. The vehicle was not yet repaired. The contact indicated that the vehicle was previously serviced under the NHTSA Campaign Number: 18V586000 (Steering) however, the failure recurred intermittently. The manufacturer was notified of the failure. The failure mileage was 75,000.
Driver side brake lights don't work again. This will be the 3rd time that I know of that this piece of equipment has been changed out.
LED Brake Lights fail due to design error typically on both side of the vehicle. I have found multiple reports of a failure on a circuit board that was poorly designed. A copper tracing is very narrow and fractures due to vibration resulting in Brake Light failure. Because the entire module must be replaced the repair costs $800-$900 per side.
LED brake light on drivers side fails to illuminate (noticed first at about 72,700 miles). Upon further research, this appears to be a recurring issue with 2015-2016 Yukon and Yukon XL vehicles. The LED taillight assembly is a sealed housing and the individual brake light bulbs are not replaceable. There appears to be a design defect that is causing premature failures of these assemblies, which results in a safety hazard because the driver does not receive any notification that the brake lights have failed.
REAR PASSENGER BRAKE LIGHT FAILURE.. KNOWN ISSUE THAT HAS BEEN NEGLECTED BY GMC.
THE AIR IN OUR 2015 YUKON HAS WENT OUT AND IS CONSTANTLY BLOWING WARM AIR. ITWILL NOT HOLD FREON. THE TEMPS IN LAS VEGAS GET INTO THE TRIPLE DIGITS. MY 78 YEAR MOTHER CONSTANTLY USES THE VEHICLE TO GET PLACES. I HAVE RESEARCHED THE PROBLEM AND SEEMS TO BE A CONSTANT PROBLEM WITH THE DESIGN OF THE AC CONDENSER AND HOSE DESIGN. WE HAVE BEEN SMELLING FREON FOR SOME TIME SO IT MUST HAVE BEEN SLOWLY LEAKING OUT. THIS SHOULD BE A RECALL PROBLEM SINCE SO MANY PEOPLE HAVE HAD THE SAME PROBLEM AND IS DEFINITELY A SAFETY PROBLEM HERE IN DESERT. THE PROBLEM IS CONSTANT, IN MOTION OR SITTING STILL.
REAR LIFTGATE WILL NOT OPEN. REPLACED LIFTGATE CONTROL MODULE AND STILL WILL NOT WORK. MECHANIC SAYS IT IS NOW BODY CONTROL MODULE. LIGHTS STAY ON INSIDE VEHICLE AT ALL TIMES AND HORN IS DISABLED
TAIL LIGHT/BREAK LIGHT WENT OUT FOR 2ND TIME. YOU CANNOT JUST PURCHASE A NEW TAIL LIGHT. THE DEALER STATES YOU HAVE TO PURCHASE A NEW TAIL LIGHT. THE DEALER WANTS $800 DOLLARS TO A NEW TAILLIGHT POD TO MAKE THE CAR SAFE AGAIN. CALLING GMC YOU NEED TO SPEND $100 DOLLARS FOR A DIAGNOSIS IN ORDER TO BE CONSIDERED FOR ASSISTANCE FROM GM WITH NO PROMISE OF ASSISTANCE.
THIS VEHICLE HAD A FAILED DRIVER'S BRAKE LIGHT AT ABOUT 60K MILES AND IT WAS REPLACED AS A RECALL ITEM. AT 76K MILES THE PASSENGER BRAKE LIGHT HAS FAILED AND WE ARE INFORMED IT IS NO LONGER A RECALL ITEM BECAUSE IT'S OUT OF THE RECALL TIMEFRAME. I'VE ALSO KNOWN 2 OTHER PEOPLE WITH YUKON'S, BOTH NEIGHBORS AND BOTH HAVE HAD AT LEAST 1 FAILED BRAKE LIGHT. IF THIS IS A KNOWN FAILURE AND SAFETY ISSUE, WHY ARE THEY DENYING RECALL AT SUCH A LOW MILEAGE.
BOUGHT THE 2015 YUKON XL AS CERTIFIED PREOWNED. WHILE STILL COVERED UNDER CERTIFIED WARRANTY, I COMPLAINED ABOUT THE INTERMITTENT TAIL LAMP FAILURE, BUT THE DEALER COULDN'T REPLICATE. YOU KNOW THE REST...THE CERTIFIED WARRANTY THEN EXPIRED BY MILEAGE, THEN THE TAIL LAMP COMPLETELY FAILED, THEN I TOOK IT BACK IN AND THEY SAY THEY WON'T COVER IT. I SPOKE TO DEALER SERVICE MANAGER, GMC CUSTOMER SERVICE (PLUS A MANAGER), BUT I"M TOLD THAT THEY WON'T ASSIST SINCE I'M OUT OF WARRANTY. I DID MY PART...I TOOK THE VEHICLE IN WHILE STILL UNDER WARRANTY AS SOON AS THE CONDITION PRESENTED ITSELF. IT'S A SHAME THAT GMC WON'T OWN THIS MASSIVE FAILURE UNTIL A RECALL ISSUED. MAYBE MY COMPLAINT WILL BE THE TIPPING POINT THAT KICKS OFF THAT PROCESS.
MAJOR SAFETY ISSUES WITH THIS VEHICLE. ANOTHER 2015 YUKON WITH NO TAIL OR STOP LIGHTS. I'M OVER MILLAGE ON SPECIAL RECALL. THERE SHOULD BE NO TIME/MILLAGE ISSUE ON THIS. SEAT BELTS LOCK UP. BRAKES ARE EITHER GOOD OR MUSSY WHENEVER THEY WANT TO BE. HARD TO STOP THE VEHICLE. ALSO WHEN I FIRST PURCHASED THE VEHICLE IT WOULD COMPLETELY DIE (NO LIGHTS MOTOR DIED, NO POWER STEERING, NO AIR BAGS, NO RADIO NOTHING AT ALL ON THE X-WAY AT 70 MPH) AND THE DEALER COULD NOT REPAIR IT! RUST ON FRAME RAILS. (AND MORE).
MY PASSENGER SIDE TAIL LIGHT ASSEMBLY NEED TO BE REPLACED AS THE BRAKE LIGHTS ARE NOT WORKING. THIS HAS BECOME A COMMON PROBLEM AS EVIDENCED BY THE NUMBER OF COMPLAINTS FILED ON YOUR SITE FOR THE SAME ISSUE. LACK OF PROPERLY FUNCTIONING TAIL LIGHTS IS A MAJOR SAFETY CONCERN AND A RECALL SHOULD BE ISSUED. *TR
RIGHT REAR BRAKE LIGHT LED KEEPS WORKING OFF AND ON. THIS IS A COMMON PROBLEM, LOOK AT THE OTHER COMPLAINTS, AND COSTS THE CUSTOMER AROUND $700 TO FIX. THE LED STRIP BREAKS INTERNALLY AND THIS IS THE CAUSE OF THE ISSUE.
I PURCHASED BY VEHICLE IN THE SUMMER OF 2015. IT HAS BEEN IN THE SHOP NUMEROUS TIMES FOR VARIOUS ISSUES, MOSTLY ELECTRICAL INVOLVING THE COMPUTER AND SOFTWARE, OR ISSUES INVOLVING MY TIRES OR STEERING WHEN TURNING THE STEERING WHEEL.. MY "DRIVER ASSIST" HAS MALFUNCTIONED MANY TIMES AND I HAVE TAKEN IT TO THE SHOP TO HAVE IT REPAIRED ON 3 SEPARATE OCCASIONS. LAST SUMMER MY FRONT AND REAR LIGHTS STARTED FLICKERING AND STOPPED WORKING. I SPENT $800 FOR THE BACK PASSENGER BRAKE LIGHT AND ALMOST $1000 FOR THE FRONT DRIVER HEAD LIGHT ASSEMBLY. I ALSO HAD TO GET A NEW BATTERY FOR THIS VEHICLE. MY 2015 GMC YUKON XL IS NOW MALFUNCTIONING AGAIN AND THIS TIME, I AM TOLD THAT THE SEAT MOTOR (THAT ALERTS YOU WHEN YOU ARE NEAR AN OBSTACLE HAS BURNED OUT.) ABOUT 4 DAYS AGO, I BECAME AWARE OF TICKING NOISE WHILE MY CAR HAS BEEN IDLE. I IMMEDIATELY SCHEDULED A MAINTENANCE APPOINTMENT. TODAY, I AM ALSO INFORMED THAT MY "LIFTERS" ARE BAD ON THE VEHICLE AND MY ENGINE IS GOING BAD. I AM TOLD THE AIR CONDITIONING CONDENSER HAS BURNED OUT, I AM TOLD THE MOTOR UNDER MY SEAT IS BURNED OUT. I HAVE PERFORMED ROUTINE MAINTENANCE, I GET OIL CHANGES REGULARLY AND USE HIGH QUALITY SYNTHETIC OILS. I TAKE MY CAR TO THE SHOP AT LEAST 2X PER YEAR FOR PROBLEMS AND SOME MAJOR REPAIR IS ALWAYS REQUIRED. THIS IS A CAR THAT I AM GOING INTO THE 5TH YEAR OF OWNERSHIP THIS SUMMER. ORIGINALLY. I WAS TOLD THAT THERE WAS A RECALL FOR BRAKES, NOW I AM TOLD THERE IS NOT, BUT I HAVE TAKEN MY CAR IN FOR VARIOUS RECALLS AT LEAST 3X. THIS IS AN UNSAFE, DEFECTIVE VEHICLE. EVERY SYSTEM FAILS. I AM NOW IN SEARCH OF A NEW VEHICLE. I HAVE DRIVEN OTHER GM VEHICLES (GRAND AM, HUMMER) AND NONE HAVE REQUIRED SO MUCH REPAIR COSTS. TODAY I AM TOLD THAT IT WILL COST $6800 TO REPAIR MY VEHICLE TO MAKE IT SAFE. MY REPAIR RECORDS WILL SHOW THE REPAIRS AND SERVICE CHARGES I HAVE PAID SINCE PURCHASE. THIS IS A LEMON. *TR
TL* THE CONTACT OWNS A 2015 GMC YUKON XL. THE CONTACT STATED THAT WATER LEAKED INTO THE ROOF OF THE VEHICLE AND SATURATED THE AIR BAG AND THE MAIN FUSE BOX. THE CONTACT STATED THAT THERE WAS A TSB FOR THE FAILURE. THE VEHICLE WAS TAKEN TO RENO BUICK GMC CADILLAC DEALER, LOCATED AT 900 KIETZKE LANE, RENO, NV 89502, (775)-815-7660, WHERE IT WAS STATED THAT THE FAILURE WAS A FACTORY DEFECT. THE TECHNICIAN REACHED OUT TO THE MANUFACTURER AND, THE MANUFACTURER AGREED TO COVER TEN PERCENT OF THE REPAIR COST. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 66,000.
NO BRAKE LIGHT IN BOTH REAR LIGHTING ASSEMBLIES. STARTED WITH THE PASSENGER SIDE AND NOW THE DRIVERS SIDE. GMC ISSUED A LETTER IN DECEMBER 2019 STATING THEY'D PAY FOR REPAIRS IF VEHICLE IS LESS THAN 6 YEARS OR 75,000 MILES WHICH EVER COMES FIRST. WE'LL I'M OVER ON BOTH. GMPP EXTENDED WARRANTY DOESN'T COVER THIS REPAIR. SPEND $75K FOR THIS TRUCK AND NOW THIS.
GMC RECENTLY ADVISED US THAT THE TAILGATE LIGHTS HAVE HAD PROBLEMS WHERE THEY "INTERMITTENTLY" DO NOT ILLUMINATE. WE HAVE HAD THIS ISSUE FOR QUITE SOMETIME WHERE DRIVERS CANNOT SEE OUR TAILGATE LIGHTS WHEN THE PROBLEM OCCURS. BECAUSE IT HAS BEEN INTERMITTENT, IT HAS BEEN VERY HARD FOR THE SHOP TO DIAGNOSE AS WHEN THEY GET IT AND IT IS ON, THEY CAN'T FIGURE OUT WHAT IS WRONG WITH IT. SINCE WE RECEIVED THE LETTER FROM GMC, WE HAVE BEEN INTO THE DEALERSHIP TO GET IT RESOLVED, BUT THEY WILL NOT DO IT BECAUSE OUR MILES ARE OVER. I HAVE TOLD THEM THAT THEY KNOW ITS AN ISSUE AND THAT IT IS INTERMITTENT AND WHEN PEOPLE TAKE IT INTO THE SHOP TO GET IT DIAGNOSE, ITS A HIT AND MISS. I HAVE NOW SEEN OVER A DOZEN OTHER GMC'S ON THE ROAD WITH THE SAME ISSUE. LAST WEEK, WHILE TRAVELING WITH KIDS TO A SOCCER TOURNAMENT, BOTH WEREN'T WORKING AT NIGHT AND WE WERE PULLED OVER. I FORTUNATELY HAD THE LETTER IN THE CAR AND SHOWED IT TO HIM. HE GAVE ME A WARNING AND ADVISED THAT IT IS VERY DIFFICULT FOR CARS TO SEE AT NIGHT WHEN THERE ARE NO TAILGATES ON AND THAT GMC HAD BETTER GET THIS RESOLVED. I HAVE MADE TWO REQUESTS WITH GMC AND THEY HAVE DENIED THE REQUEST. I EVEN TOLD THEM THAT I WOULD COST SHARE IF WE MEET IN THE MIDDLE AND THEY WOULD NOT. THEY KNOW THIS IS AN ISSUE, YET THEY AREN'T WILLING TO EXTEND THE WARRANTY OR MAKE IT A RECALL. THIS IS VERY DANGEROUS AND COULD CAUSE A LOT OF ACCIDENTS WITH GMC MODELS NATIONWIDE. I HOPE THAT THIS IS BROUGHT TO SOMEONE'S ATTENTION AND THAT GMC IS ENCOURAGED TO GET THIS RESOLVED WITH 2015 YUKON XL SUVS AND THAT WE AND MANY OTHERS ARE ABLE TO GET THEIR TAILGATES REPLACED.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
