There are 50 owner-reported electrical system complaints for the 2015 GMC Yukonin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
1) Wiring harness to the wireless charging pad on the center console that is wired through the door hinge. Shorts out when opening or closing center console. 2) Caused a fire that led to smoke and melted components inside center console hinge. Caused smoke and awful plastic burning smell while my kids and I were parked. I had just started the vehicle. My two kids and I had to jump and run from the vehicle. 3) No, but by many forums that dealers and mechanics are aware of this issue and charges you hundreds to fix it when it is MANUFACTURE ERROR. 4) This vehicle has been inspected many times. By all the other inspection laws Missouri has in place. How has it gotten passed many times with this known issue? 5)NO! This put mine and my kids life at risk. It is a known and wide issue yet no one takes this seriously. As it just affected me and my two children, I hope this is taken seriously. Hold manufactures responsible and dealers for selling vehicles with these known issues. Protect people.
Air intake stayed on after shutting vehicle off and locked. It seemed it was in auto start mode from the key fob. Now it is hesitating to go and struggling to switch gears. Local mechanic is unable to pinpoint issue. Will bring to GMC dealership next. The rear camera intermittently works. If you open and close it sometimes it will fix it. USB ports intermittently work. Both taillights had to be replaced due to intermittently going out. Both front heated seats only work on top.
The engine turns off when driving. This has happened at least 50 in the 2 years I've owned the vehicle. It has been serviced at Garland Shelton GMC in Temple, TX. The issue is not fixed. The battery and the negative cable have been replaced. When the engine dies none of the electrical works until I open the hood and wiggle the negative battery cable.
Trailer break system warning keeps appearing.
The problem initially started around August 19th when my daughter was driving the SUV. It started suddenly flashing multiple service problems ex trailer brake service, park assist service and stability track service. It started flashing them over and over every second and the engine would rev up then slow down which continued even after she was able to pull over and get it into park. It was terrifying for her. We had the vehicle towed to GMC. GMC felt the electrical problems were due to the fuse box so they replaced the entire fuse box and changed all the fuses. Last week, my daughter again was driving home on the highway and the vehicle started doing the same warning but also displayed several more warnings and the car was lurching forward and slowing down over and over again despite trying to maintain a safe speed. She was close to home and thankfully made it safely home. I drove the car the next morning a few miles to see what was going on and it started doing the same thing with alerts, servicing cycling through the dashboard and the speed and rpm kept revving up and slowing down, I could not maintain a steady slow speed as it seemed like the car was braking every few seconds so it kept lurching forward out of control. We had the car again towed to the same GMC. This time GMC changed out all the battery cables going to and from the batter itself. My husband picked up the car a few days later after being told the problem had been fixed. Within a couple miles of leaving the dealership (and thankfully before getting on the highway) the car started again with the lurching, revving and continuous flashing of a multitude of service alerts/failures. GMC had the car towed back to the service center where it has remained as they run more diagnostic tests. We are concerned that there is a serious electrical problem that they have been unable to figure out on this vehicle which has put each of us at serious safety risk when trying to drive it.
THE TAIL LIGHTS FLICKER AND SOMETIMES DON'T WORK AT ALL.
BOTH REAR TAIL LIGHTS ARE INOPERABLE AND THE DEALER WANTS OVER $800 TO REPLACE. I'M OVER THE MILEAGE LIMIT FOR THE RECALL SO I'M OUT OF LUCK.
Trailer Brake connection gives errors. Has been fixed multiple times with dealer with error still occurring
SO MY BRAKE LIGHT ON REAR ALL HAVE GONE OUT DUE TO BAD LED LIGHTS OR SOME KNOWN COMPONENT GOES BAD. #2. FUEL PUMP IS BAD. #3 RADIATOR HAS A CRACK IN IT. THIS IS A 2015 YUKON
THE DOOR LOCK ACTUATOR WORKS INTERMEDIATELY. I CAN'T ALWAYS UNLOCK OR LOCK THE DOOR WITH THE KEY FOB AND THERE IS NOT A MANUAL ENTRY.
REAR TAIL LIGHTS NOT WORKING. BOTH TAIL LIGHTS REQUIRE REPLACEMENT. THERE IS AN OPEN RECALL FOR 2016 GMC YUKON'S WHY IS THERE NOT AN OPEN RECALL FOR 2015? THIS IS OBVIOUSLY AN ISSUE BASED ON THE NUMBER OF COMPLAINTS MADE / REPORTED HERE. *TR
BRAKE LIGHT GOES OUT DUE TO WIRING ISSUES. *TR
BOTH TAILLIGHTS INTERMITTENTLY STOP WORKING. *TR
ONSTAR/ GPS ANTENNA ELECTRICAL SHORT AND CORROSION. SEAL ON ANTENNA COVER INCORRECTLY INSTALLED/ DEFECTIVE. *TR
REAR TAILLIGHT DOES NOT WORK. SEARCHED ONLINE AND FOUND THAT THIS IS A VERY COMMON ISSUE, GM REFUSES TO FIX AND TRIES TO CHARGE $800 TO REPLACE WHOLE TAIL LIGHT ASSEMBLY, AND THEY REPLACE WITH SAME FAULTY LIGHTS! FIX IT GMC, RIDICULOUS
Drivers side tail light intermittently works, doesn't work all the time. Passenger side brake light stays on continuously, never changes.
TL* THE CONTACT OWNS A 2015 GMC YUKON. THE CONTACT STATED THAT THE BRAKE LIGHT FAILED TO ILLUMINATE WHEN THE BRAKE PEDAL WAS DEPRESSED. THE CONTACT RECEIVED A CUSTOMER SATISFACTION PROGRAM REGARDING THE BRAKE LIGHT. THE CONTACT WAS INFORMED THAT THE VEHICLE WAS INCLUDED IN NHTSA CAMPAIGN NUMBERS: 18V586000 (STEERING) AND 19V645000 (SERVICE BRAKES, HYDRAULIC). STANLEY WOOD CHEVROLET BUICK GMC (1674 BATESVILLE BLVD, BATESVILLE, AR 72501, (870) 390-4093) WAS CONTACTED AND AN APPOINTMENT WAS SCHEDULED TO HAVE THE VEHICLE REPAIRED UNDER THE RECALLS. THE CONTACT WAS ALSO INFORMED THAT THE MILEAGE WAS EXCEEDED UNDER THE CUSTOMER SATISFACTION PROGRAM. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 113,000.
BRAKE LIGHTS WILL INTERMITTENTLY STOP WORKING. NO CONSISTENCY TO WHEN THEY STOP WORKING OR WHEN THEY START AGAIN. MAJOR SAFTEY HAZARD. GMC KNOWS ABOUT THE PROBLEM BUT ARE CALLING IT AN EXTENDED WARRANTY ISSUE, AND NOT FIXING VEHICLES OUTSIDE THEIR DESIGNATED TIME/MILEAGE BECAUSE THEY SAY IT IS NOT A SAFETY HAZARD...' IT IS!!!
RIGHT REAR LED TAIL/BRAKE LIGHT STOPPED WORKING. NOT EASILY FIXABLE. DEALERS ARE AWARE OF THE PROBLEM AND MAKE YOU PAY $700+ A PIECE FOR A WHOLE NEW ASSEMBLY. THE ISSUE APPEARS TO BE A FAULTY CIRCUIT BOARD INSIDE. THIS SHOULD BE SOMETHING THAT CAN BE TAKEN APART AND FIXED EASILY OR GM SHOULD REPLACE IT FOR FREE.
REAR BRAKE LIGHT ASSEMBLY FAILING TO LIGHT WHEN BRAKES APPLIED AND THERE IS NOT A NOTIFICATION TO THE DRIVER. THIS IS A MANUFACTURE FLAW WITH THE LED LIGHT CIRCUIT INSIDE THE ASSEMBLY. THERE IS NOT A LIGHT OUT NOTIFICATION SO THE DRIVER IS NOT AWARE THE BRAKE LIGHT HAS FAILED. THIS IS A SAFETY ISSUE AND IS AN WELL KNOWN ISSUE ON THE 2015-2019 YUKON. THIS IS OCCURRING OFTEN AND GMC IS HAVING PROBLEMS WITH SUPPLYING REPLACEMENTS BECAUSE THE DEMAND IS SO HIGH FROM THE FAILURE. GMC HAS ALSO RAISED THE PRICE OF THE BRAKE LIGHT BY 30% FROM $425 TO $675 NOT INCLUDING LABOR. I CALLED THE DEALER AND THEY INFORMED IT WAS A HIGH FAILING ITEM AND WAS ON BACKORDER AND NOT SURE WHEN THEY WOULD GET ONE. DRIVING THE VEHICLE WITHOUT PROPER BRAKE LIGHTS IS A SAFETY CONCERN AND NOT LEGAL SO LEFT WITH LITTLE OPTION BUT TO STOP DRIVING THE YUKON.
