2015 GMC YUKON XL Unknown Or Other Problems

I purchased a 2015 GMC Yukon in March 2024 I drive the vehicle 9 mons, 7500 miles the vehicle has been in service at my local dealership since Dec 13, 2024, for engine and transmission replacement, I have had the vehicle back 3 weeks not the warning light and service warning chime for the "Service Trailer Brake System is on, I have not ever use a trailer with the vehicle, I was told the vehicle needs a wire harness, I have read this a problem in these vehicles that has not been addressed GMC with a recall, I have put A LOT of money in the vehicle. This is an well documented failure in the trailer brake system that GM should repair at no cost to the consumer

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.

Trailer brake system keeps beeping and nothing is wrong, had it checked out several times.

Trailer assist error. Brakes not working. Ac compressors been replaced and the fan runs after the vehicles off and ac only blows warm air

Vehicle has a vibration in the gas pedal and shifts hard at times. The whole vehicle shakes. Even after I purchased a new set of tires I took it back twice thinking it was out of balance but that was not the case. Beyond aggravated with this vehicle and its issues!

WHEN DRIVING BETWEEN 40-70 MILES AN HOUR. I FEEL A VIBRATION SOMEWHERE IN THE VEHICLE. THE VIBRATION FEELS LIKE U ARE ROLLING OVER RUMBLE STRIPS. THIS HAPPENS TIME AND TIME AGAIN ON THE HIGHWAY, WHILE IN MOTION ONLY.

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.

ABOUT A MONTH AGO, I BEGAN TO RECEIVE AN ALERT THAT MY SIDE DETECTION SYSTEM NEEDED TO BE SERVICED. UPON INSPECTION, MY RIGHT SIDE MODULE HAD TO BE REPLACED. AFTER COMPLETING THE REPAIR, THE NEW MODULE WOULD NOT COMMUNICATE WITH THE LEFT MODULE WHICH IS HOW THE RIGHT MODULE GETS PROGRAMMED. IT WAS DISCOVERED THAT EVEN THOUGH THERE WAS NO ALERT THAT THE LEFT MODULE NEEDED TO BE REPLACED AS WELL. THIS IS A HUGE CONCERN THAT THESE MODULES WOULD FAIL THIS SOON INTO THE VEHICLE'S LIFE (68,000 MILES). THERE ARE NO MOVING PARTS, ETC. NOT TO MENTION THE SAFETY ISSUES OF NOT HAVING A WORKING SIDE COLLISION ALERT SYSTEM.

I PURCHASED MY VEHICLE OCTOBER 31'ST 2019 FROM A LOCAL DEALERSHIP. THE MILAGE WAS ABOUT 74K MILES. I HAVE ONLY HAD THIS VEHICLE FOR A FEW MONTHS. MY CONCERN IS THE FOLLOWING. WHILE DRIVING, AT LEAST 7 TO TEN TIMES THE VEHICLE COMPLETELY STALLS. IN OTHER WORDS IT COMPLETELY STOPS. THE STEERING WHEEL LOCKS. ALL POWER IS LOST. NO LIGHTS NO NOTHING. THIS HAS HAPPENED AT INTERSECTIONS, IT HAS HAPPENED WHEN TURNING LEFT, IT HAS HAPPENED WHEN TURNING RIGHT. IT HAPPENS WHEN WE ARE YIELDING. SOMETIMES THE DASH STARTS TO FLICKER AND ALSO THE CONSOLE. SOMETIMES LIKE TODAY WITHOUT ANY WARNINGS. THIS IS PUTS ME AND MY FAMILY IN A VERY DANGEROUS SITUATION. PLEASE RESPOND ASAP. I CURRENTLY HAVE 86K MILES ON MY VEHICLE.

Mileage: 86

OWNED THE CAR FOR 2 YEARS, BEEN IN THE SHOP THREE TIMES FOR THE SAME ISSUE, CAR JERKS GOING LESS THAN 25 MPH AND WHILE DRIVING AND ACCELERATING. BOTH TAIL LIGHTS ARE LED AND INOPERABLE. AC QUIT WORKING, RECHARGED ONCE AND FIGURE IT'S A LEAK. UPON READING REVIEWS GMC IS AWARE OF FAULTY PARTS BUT NO RECALL ON ANY VEHICLE.

Mileage: 127,000

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.

WHEN DRIVING AT LOW SPEED 40MPH AND UNDER YOU CAN BARELY FEEL THE VIBRATION/SHAKING BUT WHEN YOU GET UP TO HIGHWAY SPEED 60-75MPH THE TRUCK REALLY STARTS TO VIBRATE/SHAKE IF THE HIGHWAY HAS ANY TURNS OR CURVES IT SHAKES/VIBRATES EVEN MORE UNTIL YOU START GOING STRAIGHT AGAIN THEN IT CALMS DOWN AND SHAKES/VIBRATES AS IT ALWAYS DOES ALSO IF SLOW DOWN IT WILL SHAKE/VIBRATE LESS BUT NEVER COMPLETELY STOPS I TOOK IT TO MY LOCAL DEALER BECAUSE I HEARD THESE TRUCKS WERE HAVING PROBLEMS WITH THE TORQUE CONVERTER SHUTTERS BUT WAS TOLD THAT THE TIRES NEED TO BE BALANCED WITCH DIDN'T SOLVE THE PROBLEM I WAS THEN TOLD THAT IT WAS NORMAL FOR THESE TRUCKS WITCH I DIDN'T BELIEVE I EVEN TRIED A DIFFERENT SET OF WHEELS AND TIRES WITCH DID HELP EITHER IT SHAKES/VIBRATES SO MUCH THAT I DON'T WANT TO DRIVE IT BECAUSE YOU GET A HEADACHE THIS HAS BEEN A ON GOING PROBLEM FOR A YEAR AND A HALF I REALLY STARTED NOTICING IT AROUND 75,000 MILES THERE ARE A LOT OF CLAIMS OF THE SAME PROBLEM/SYMPTOMS ON THE WEB

THERE IS A KNOWN ELECTRICAL ISSUE WITH THE YUKON TAIL LIGHTS. THE ENCLOSED LED RUNNING LIGHTS AND BRAKE LIGHTS WILL GO OUT AND NOT OPERATE. THIS IS A HUGE SAFETY CONCERN AS THERE IS NO BRAKE LIGHT THAT WILL ILLUMINATE AND NO RUNNING LIGHT. BOTH OF MY TAIL LIGHTS HAVE GONE OUT ON MY VEHICLE. DURING A RECORD CHECK I HAVE LEARNED THAT THIS IS A COMMON PROBLEM WITH THE YUKON'S. GMC HAS FAILED TO TAKE ACTION ABOUT THE KNOWN PROBLEM. THE PROBLEM IS PERSISTENT WHILE BEING STOPPED AND DRIVING. SECONDLY THE BRAKING VACUUM SYSTEM WILL GO OUT UNEXPECTEDLY. THIS CAUSES THE ASSISTED BRAKES TO FAIL CAUSING THE BRAKING SYSTEM NOT TO TAKE AFFECT AND STOP THE VEHICLE PROPERLY. THIS IS A HUGE SAFETY CONCERN AS YOU WILL NOT BE ABLE TO SAFELY STOP YOUR VEHICLE IN A TIMELY MANNER AND WILL CAUSE SEVERAL ACCIDENTS. I NOTICED THAT THE BRAKES HAD FILLED WHILE BEING STOPPED AT A STOPLIGHT AND ALSO WHILE BEING MOBILE AND DRIVING.

AS I WAS DRIVING MY VEHICLE YESTERDAY AFTER IT WAS RAINING, THE DRIVER'S SIDE SUN VISOR LEAKED WATER. I WAS TOLD BY MY GMC DEALERSHIP THAT THE VISOR IS LEAKING DUE TO THE ANTENNA ON THE TOP OF MY VEHICLE. (I DO NOT HAVE A SUN ROOF) SO, MY HEADLINER IS WET AND THE ANTENNA NEEDS TO BE REPLACED. I WAS TOLD BY MY GMC DEALERSHIP (I WORK FOR THE FAMILY THAT OWNS THE DEALERSHIP) THAT THE ANTENNA IS NOT COVERED UNDER A RECALL. I DO NOT THINK I SHOULD HAVE TO PAY FOR A DEFECT IN MY ANTENNA! THE MANUFACTURER THAT MADE MY VEHICLE SHOULD PAY FOR THE REPLACEMENT OF THE ANTENNA NOT ME! IT IS NOT SOMETHING THAT I HAVE DONE TO THE VEHICLE. IT IS A DEFECT IN MANUFACTURING! I WOULD LIKE FOR GM TO PLACE A RECALL FOR THE ANTENNA TO BE REPAIRED FREE OF CHARGE. AGAIN, I WORK WITH THE GMC DEALERSHIP AND THEY HAVE HAD OTHER CUSTOMERS COME IN WITH THE SAME COMPLAINT! AGAIN, I SHOULD NOT HAVE TO PAY FOR THE REPLACEMENT OF THE ANTENNA OR FILE A CLAIM WITH MY WARRANTY COMPANY. THIS IS A DEFECT!

MY VEHICLE HAS A SIGNIFICANT VIBRATION WHEN TRAVELING 40MPH AND ABOVE WITH A REAR WINDOW DOWN. THE VIBRATION IS ALSO ACCOMPANIED BY INCREASED CABIN PRESSURE. THESE ISSUES ARE CAUSING HEADACHES, NAUSEA, AND DIZZINESS. DEALERSHIP CONFIRMS ISSUE AND TRIED TO REPAIR, BUT UNABLE TO. THE VIBRATION STARTED RIGHT AFTER WE TOOK DELIVERY OF THE CAR AND HAS ONLY GOTTEN WORSE. WE BOUGHT THE CAR IN OCTOBER 2015 AND THE ISSUE CONTINUES UNFIXED TO THIS DAY AFTER 5 VISITS.

Mileage: 18,500

AC CONDENSER FAILURE

MY 2015 GMC YUKON XL WITH 5000 MILES EXHIBITS A BUFFETING / PRESSURE SENSATION THAT CAN BE FELT PREDOMINATELY IN THE EARS BETWEEN 30 AND 70 MPH WHEN ONLY THE REAR PASSENGER WINDOWS ARE DOWN . AFTER A SHORT AMOUNT OF TIME IT BEGINS TO CAUSE DIZZINESS, EAR PAIN, AND HEADACHES. SOMETHING IS VERY WRONG AND MUST BE FIXED

ON THE DAY I TEST DROVE MY YUKON MY HUSBAND AND I NOTICED A VIBRATION IN THE VEHICLE. WHEN WE RETURNED TO DEALER NOTICED ONE OF THE RIMS WAS DIFFERENT THAN THE OTHER THREE SO WE ALL BELIEVED IT WAS THE CAUSE. WAS TOLD IT WOULD BE HANDLED. SO WE CAME BACK TO PICKUP AND THAT'S WHERE IT ALL BEGAN. THIS VEHICLE HAS SEVERE REVERBERATION AND VIBRATIONS. REVERBERATION CAUSES SEVERE HEADACHES AND NAUSEA. MY DRIVING LEG GOES NUMB FROM THE VIBRATION THAT COMES THRU THE GAS PEDAL. SO UNSAFE. SEVERE TUNNELING VIBRATION THEY HAVE DONE THE TIRES NOT THE PROBLEM. REPOSITIONED UPPER AND LOWER REAR CONTROL ARMS TO CHANGE PINION ANGLE &CHECKED AND ADJUSTED TRANSMISSION CROSS MEMBER AND MOUNT. PICKED IT UP IMMEDIATELY NOTICED NOTHING HAD CHANGED. WHEN RIGHT BACK TO DEALER AND SERVICE MANAGER DROVE WITH ME. HE ALSO AGREED THAT IT WASN'T FIXED. BROUGHT BACK AGAIN. AFTER DOING ANOTHER SERIES OF THINGS GMC REP DROVE VEHICLE AND SAID THAT PICO SCORES FALL UNDER SPECS. OFFERED ME A ADDITIONAL 2YR/24000 MILE WARRANTY. HAHA I TRADE EVERY THREE YEARS AND PUT 6000 MILES PER YEAR ON MY SUV. SO ON 1/28/16 THE PICO SCORE WAS 20 BEFORE THE REPAIRS CLAIMED THEY GOT IT DOWN TO 5. PICKED IT UP BROUGHT IT BACK TO DEALER 2/3 (I'VE PUT 45 MILES ON BETWEEN SERVICES) TAKE IT BACK OUT ON ROAD PICO BACK AT 20 DID MORE STUFF GOT IT BACK DOWN TO 6. SO GM REP SAYS IT'S WITHIN GM SPECS?? THIS IS CRAZY. JUST TOOK DISABLED HUSBAND TO DR AND HE COULD HARDLY MAKE IT HOME IN THIS VEHICLE. THIS IS A SEVERE HEALTH CONCERN. DOES SOMEONE HAVE TO HAVE AN ACCIDENT AND KILL SOMEONE BEFORE THIS IS ADDRESSED. I HAVE ACTUALLY STUMBLED AFTER GETTING OUT OF THIS VEHICLE DUE TO THE REVERBERATION AND MY EQUILIBRIUM BEING OFF BECAUSE OF IT. I HAD WKED FOR A GM DEALER FOR 25 YEARS THAT'S WHEN THEY USED TO TAKE CARE.OF THERE CUSTOMERS. I HAVE DRIVEN AND OWNED 20 SUBURBAN & YUKONS I HAVE NEVER HAD ONE LIKE THIS. CONCLUSION: NOT FIXED

WITH ALL WINDOWS UP, VEHICLE EXHIBITS A BUFFETING / PRESSURE SENSATION THAT CAN BE FELT PREDOMINATELY IN THE EARS BETWEEN 30 AND 50 MPH. SIMILAR TO WHEN ONLY THE REAR PASSENGER WINDOWS ARE DOWN IN MANY VEHICLES. I SECOND THE FACT THAT AFTER ANY AMOUNT OF TIME AT THESE SUSTAINED SPEEDS IT BEGINS TO CAUSE DIZZINESS, EAR PAIN, AND HEADACHES. GM FORUMS ARE FLOODED WITH COMPLAINTS. THIS VEHICLE OBVIOUSLY WAS MANUFACTURED WITH A SIGNIFICANT, KNOWN FLAW THAT THEY CANNOT CURRENTLY FIX. THIS SHOULD ABSOLUTELY BE A SAFETY ISSUE STRICTLY BASED UPON THE PHYSICAL SYMPTOMS ONSET BY THE FEELING WITHIN THE VEHICLE.

HORRIBLE CABIN PRESSURE AND BUFFETING ABOVE SPEEDS OF 40MPH. PASSENGERS HAVE COMPLAINED OF HEADACHES, DIZZINESS, EARS POPPING, ETC. OCCURS WITH ALL WINDOWS AND SUNROOF CLOSED. DURING LONG PERIODS IT CAN SOMETIMES CREATE NAUSEA AND SICK FEELING EVEN HOURS AFTER EXITING TRUCK.

VEHICLE EXHIBITS A "BUFFETTING" OR PRESSURE SENSATION THAT CAN BE FELT PRIMARILY IN THE EARS BETWEEN 40 AND 50 MPH. AFTER ANY AMOUNT OF TIME AT THESE SUSTAINED SPEEDS IT BEGINS TO CAUSE DIZZINESS, EAR PAIN, AND HEADACHES. THIS CONDITION WAS CONFIRMED BY THE DEALER WITH 3 SEPARATE DRIVERS INCLUDING A TECH, THE SALES MANAGER, AND THE OWNER. GM HAS A TECHNICAL PI ISSUED, AS THE PROBLEM IS APPARENTLY RELATIVELY COMMON IN THESE VEHICLES. SUGGESTED REPAIRS INCLUDE RE-BONDING THE ROOF SHEET METAL TO THE FRAME, REPAIR/REPLACEMENT OF THE REAR DIFFERENTIAL, REPLACEMENT OF THE PROPSHAFT, REPAIR/REPLACEMENT OF WHEELS AND TIRES, REMOVAL AND "RELAXING" OF THE EXHAUST SYSTEM, AND MORE. NONE OF WHICH APPEARS TO SOLVE THE ISSUE. A QUICK INTERNET SEARCH TURNED UP DOZENS OF CASES WITH THIS ISSUE IN JUST ONE WEBSITE. GM HAS MANUFACTURED A VEHICLE WITH A SIGNIFICANT, KNOWN FLAW THAT THEY CANNOT CURRENTLY FIX. THIS FLAW SHOULD BE CONSIDERED A SAFETY ISSUE STRICTLY BASED UPON THE PHYSICAL SYMPTOMS TRIGGERED BY THE SENSATION WITHIN THE VEHICLE.
