Owners have filed 404 complaints
about the 2015 GMC Yukon XL with NHTSA between 2015 and 2026.
The largest single group is the lights.
Across this model's run it ranks 5 of 27 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 100
Against the median year of the GMC Yukon XL. 50 means typical for this
model; 100 means roughly double.
Severity — 22
4.2% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 22
13% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2015 GMC Yukon XL
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Brake Vacuum Pump Failure
On November 20, 2018, the Office of Defects Investigations (ODI) opened PE18-012 to investigate instances of sudden onset of a hard brake pedal that could result in extended stopping distance due to an issue with the brake assist vacuum pump in model year (MY) 2014 through 2016 GMC Sierra 1500 and Chevrolet Silverado 1500 series pickup trucks and MY 2015 through 2016 Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon SUVs.If the brake assist vacuum pump fails to operate as intended, the amount of brake power assist supplied to the driver can be significantly reduced, extendi...
Recalls on the 2015 GMC Yukon XL
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 20194205,327 units in Canada
Other
Issue: This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act. Safety Risk: Glass that breaks in to large pieces could create a risk of injury. Corrective Actions: The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.
Recall 2019324310,121 units in Canada
Brakes
Issue: On certain vehicles, there could be a reduction in power brake assist due to a decrease in output from the vacuum pump. This could cause a hard brake pedal and an increase in brake pedal effort to stop the vehicle. Safety Risk: A sudden increase in brake pedal force could lead to an increase in stopping distance. This could increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a dealer to reprogram the electronic brake control module.
Recall 2017342152 units in Canada
Airbag
On certain vehicles, the sensing and diagnostic module (SDM), which controls airbag and pretensioner deployment, contains a software defect which may prevent the deployment of frontal airbags and pretensioners in certain circumstances. Failure of frontal airbags and seatbelt pretensioners to deploy in a crash (when warranted) could increase the risk of injury. Correction: Dealers will reflash the SDM with new software. In vehicles with any previous deployment events recorded in the SDM, the dealers will replace the existing SDM with a new SDM containing the latest software.
Recall 20165021,435 units in Canada
Tires
On certain vehicles equipped with Continental P275/55R20 CrossContact LX20 tires, a manufacturing defect could cause a lack of adhesion between belts in the tire. Affected tires may exhibit localized tread wear, excessive vibration, noise and bulging in the tread area. Continued use could cause the belts to separate, which could lead to full belt/tread loss. This could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect tire date code markings to determine whether they are from the affected date code. Affected tires will be replaced.
Recall 2016439362,263 units in Canada
Airbag
On certain vehicles, the sensing and diagnostic module (SDM), which controls airbag and pretensioner deployment, contains a software defect which may prevent the deployment of frontal airbags and pretensioners in certain circumstances. Failure of frontal airbags and seatbelt pretensioners to deploy in a crash (when warranted) could increase the risk of injury. Correction: Dealers will reflash the SDM with new software. In vehicles with any previous deployment events recorded in the SDM, the dealers will replace the existing SDM with a new SDM containing the latest software. Note: This recall affects 2014-2017 model year Sierra LD/Silverado LD models and 2015-2016 model year Sierra HD/Silverado HD model vehicles.
Recall 20145533,540 units in Canada
Lights And Instruments
Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard 108 - Lighting System and Retroreflective Devices. If the headlamp switch is rapidly and repeatedly cycled between positions (at least two cycles within 0.6 seconds), park lamp and daytime running light function could be disabled, which is contrary to the requirements of the standard. Correction: A production change has been undertaken to remedy this technical non-compliance condition. No corrective recall action is required as the technical non-compliance condition is deemed to be non-safety related.
Recall 201425453,607 units in Canada
Powertrain
Certain vehicles equipped with an Automatic Transfer Case may have a condition in which an electric signal short may cause the transfer case to switch to neutral without operator input. The transfer case mode selection knob would still indicate the last selected drive mode, but the driver would not have any feedback that the transfer case is in neutral. If the transfer case switches to neutral while the vehicle is in motion, the driver would experience a loss of motive power and, if the vehicle is parked without the parking brake applied, the vehicle could roll away. Both scenarios could result in a crash causing injury and/or damage to property. Correction: Dealers will re-program the software of the Transfer Case Control Module.
Recall 20142165,439 units in Canada
Accessories
Certain vehicles equipped with a base radio and internal amplifier may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 114 - Theft Protection and Rollaway Protection, and CMVSS 208 - Occupant Crash Protection. The radio may become inoperative, causing a no-chime condition and disabling the audible warning if the key is in the ignition and the driver’s door is opened, or if a front outboard seat belt is not buckled. A loss of the seat belt audible warning may increase the likelihood of a front outboard occupant being unbelted, increasing the risk of injury in a crash. Similarly, the loss of an audible warning when a key is left in the ignition may increase the risk of vehicle theft. Correction: Dealers are to program the radio with updated software.
Reports where the owner recorded a crash, a fire, an injury or a death.

I was dropping my daughter off at school in the car line. I was at low speed trying to brake and with the brake all the way down couldn't stop immediately. I was able to stop but then went to go again and when tried to stop again, couldn't and hit the car in front of me. It was making a sound while trying to brake but wouldn't engage my brakes. Luckily it didn't leave any damage and the other driver said it was OK and accepted my apology as my brakes were not working correctly.

THE BRAKES FAILED IN MY CAR CAUSING A REAR COLLISION WITH AN OBJECT IN MY DRIVEWAY. AFTER INSPECTION FROM A CERTIFIED GMC DEALERSHIP, THE BRAKE FAILURE WAS NOT CAUSED BY SERVICE NEGLECT OR AGE OF BRAKES, IT WAS DUE TO THE VACCUM PUMP FAILURE TO PROVIDE PRESSURE. THIS IS THE SECOND TIME IN TWO YEARS THIS PART HAS CAUSED MY BRAKES TO FAIL. THE DEALERSHIP REPLACED THE PART AT NO COST THOUGH THERE IS NOT FORMAL RECALL ON THIS PART. BOTH TIMES THIS PART FAILED THE CAR WAS IN MOTION. THE FIRST TIME IT WAS TOWED OUT OF A CITY TO BE REPAIRED AS IT WAS DANGERSOUS TO DRIVE AND THE SECOND TIME THE FAILURE CAUSED THE VEHICLE TO COLLIDE WITH A LARGE DUMPSTER IN MY DRIVEWAY CAUSING EXTENSIVE DAMAGE TO THE REAR PASSENGER SIDE OF THE CAR. THANKFULLY THERE WAS NOT PHYSICAL DAMAGE TO ANY PERSONS IN EITHER OF THESE TWO INCIDENTS WHICH BOTH WERE NO FAULT OF THE DRIVER OR OWNER OF THE CAR.

OUR 2015 YUKON XL DENALI CAUGHT FIRE IN THE ENGINE COMPARTMENT WHILE WAITING AT STOP LIGHT ON SAT, WITH MY WIFE AND CHILDREN INSIDE. IT WAS A HOT DAY, OVER 95 DEGREES, AND WE WERE TURNING LEFT ACROSS TRAFFIC WHEN WE REALIZED THE SMELL AND SMOKE WAS COMING FROM OUR VEHICLE. SMOKE WHIFFED FROM UNDER THE HOOD AND NOXIOUS FUMES FILLED THE PASSENGER COMPARTMENT, SCARING ME AND MY FAMILY. WE FINISHED THE TURN AND IMMEDIATELY PULLED OVER, SHUTOFF THE TRUCK, AND ALL ESCAPED FEARING IT WOULD BURST INTO FLAMES. WHATEVER WAS BURNING APPEARED TO STOP ONCE THE IGNITION WAS OFF. I OPENED THE DRIVER DOOR, POPPED AND RAISED THE HOOD TO LOOK FOR THE PROBLEM. I COULD SEE THAT A BELT, BEHIND THE SERPENTINE BELT, HAD SNAPPED, AND THERE WAS CHARRED DEBRIS ON THE EXPOSED MECHANICAL PULLEY FOR THE AC COMPRESSOR. AFTER FURTHER INSPECTION, I RESTARTED THE TRUCK WITH THE AC OFF, AND MONITORED FOR SMOKE. THE TRUCK SEEMED OK TO DRIVE HOME , SO WE DID WITHOUT AC ON A 95 DEGREE DAY. ON MONDAY WE DROVE THE TRUCK TO A TRUSTED MECHANIC FOR INSPECTION. THEY DIAGNOSED THE COMPRESSOR SEIZED AND ESTIMATED REPAIRS WERE $1,240. THE TRUCK IS GARAGED KEPT, AND GENTLY USED WITH ONLY 37,500 MILES. WE PURCHASED THE GMC CERTIFIED TRUCK IN JULY 2018 FROM A DEALER. I CREATED AN ACCOUNT ON GMC.COM & LOOKED THROUGH WARRANTY COVERAGE. A SPECIAL COVERAGE HAD BEEN EXTENDED FOR AC DEFECTS, BUT IT LAPSED IN MARCH, 2020. LOOKING FURTHER; MANY THOUSANDS OF GM OWNERS HAD SAME PROBLEM FROM SAME DEFECTIVE AC CONDENSER COMBI-COOLER. I CALLED GM TO COMPLAIN THEY NEVER TOLD US OF ABOUT A DEFECTIVE AC SYSTEM. THEY SAID ONLY A GM DEALER COULD DIAGNOSE THE PROBLEM, BECAUSE THEY ARE 'EXPERTS'. THAT SAME 'EXPERT' DEALER HAD SERVICED OUR YUKON 4 TIMES OVER THE PAST 2 YEARS AND NEVER ONCE SHARED THE INFORMATION ABOUT THE DEFECTIVE AC SYSTEM. GM & DEALER COLLUDED TO ALLOW WARRANTY TO EXPIRE.

The Active Fuel Management (AFM) system malfunctioned causing not all engine cylinders to fire at critical times, thus causing a safety issue when the vehicle has insufficient power traveling at highway speed. The AFM is intended to transition from 8 cylinder power to 4 cylinder power to save fuel. However it malfunctioned so that it couldn't transition back from 4 cylinder power. The malfunction occurred while driving at highway speed, approximately 70 mph and towing a trailer. There were no warning messages or other symptoms prior to the failure. This malfunction necessitated removal and replacement of the engine. A certified mechanic completed the repair work.

My transmission is causing a lot of shaking and hard shifting and it's very detrimental to my physical and psychological health. I am a disabled veteran with back problems and every time my Yukon shakes (almost every single shift) it hurts my back and makes it difficult to do anything. This is a very, very common issue with this year make and model but nothing seems to be getting accomplished. GM needs to remedy these issues as a recall since most of us can't afford the $5000-$12000 that this type of repair is going to cost us and GM knows that this is an issue. I can't continue to risk my family's health and safety with this vehicle and it needs to be fixed immediately!

In the past 2 months, the rust has caused a massive hole underneath the rear passenger's side door and we have had no choice but to get it repaired. The initial estimate for this single repair is going to be over $3400. This rust easily could've broken down further and gotten into the brakes and other components right behind it as it sits very close to the wheel well. This is an absolutely dangerous issue and should be addressed.

In December 2024 took my GMC Yukon XL to a mechanic. They replaced the lifter in the driver side of the engine. 2500 miles later it is back in the shop for the same side. Now there is a bent rod. One of the lifter/Rod spots collapsed. The mechanic is in contact with the local GMC dealer to figure out what the next steps are. The recent symptoms had to have car towed back to Fairly reliable Bobs mechanic. Pictures were taken and sent to GMC. First time this happened I heard a Tic in the engine and took it straight to the mechanic. second time this happened. Engine light came on flashing, Trackton light came on, Lost power, there was a shimmy when slowing down and a shake at the stop. I will note the second time this happened below.

While driving, the check engine light started to blink and there was a steady knocking coming from the engine. This is the same issues that GMC is currently recalling newer model vehicles for. Safety was at risk because the engine failure happened while driving.
