  THE AIR CONDITIONING IN MY 2017 YUKON XL STOPPED BLOWING COLD AIR. THERE IS A KNOWN ISSUE WITH GMC CONDENSERS. I BROUGHT MY YUKON TO THE DEALERSHIP AND WAS TOLD THAT INDEED IT WAS THE CONDENSER WHICH CAUSED REFRIGERANT TO LEAK. HOWEVER, IT WAS NOT COVERED UNDER THE SPECIAL COVERAGE ADJUSTMENT 17336 AS MY VIN # WAS NOT INCLUDED FOR SOME REASON. SAME PROBLEM, BUT I HAVE TO PAY FOR THIS OUT OF MY POCKET - $1200.

  I purchased a 2017 yukon xl denali. In the short time that I have had the vehicle the transmission has started to make a loud audible popping noise when coming to a complete stop. I have take the vehicle to the GM dealership multiple times to try and get the problem fixed and according to them it is something with the transmission that they don't know exactly how to fix. So I am stuck with this 8l90 transmission that is a piece of junk and can't even get a rebuilt transmission from companies like Jasper due to the issues of these transmissions.

  On July 3, 2025 we were traveling on a 4 lane at 55mph. Without any prior symptoms, the vehicle began to shake violently. It shook so hard that the skid warning light simultaneously came on. It was followed by the check engine light. The oil pressure guage started bouncing around. We stopped driving the vehicle and had it towed to VanYork GMC dealer in Asheboro, NC on this same day. (Invoice attached) VanYork GMC determined that cyclinder 5 was misfiring. We paid to have them repair it, and we began driving the vehicle again. (invoice attached) On or about August 1, 2025 we were traveling on an interstate at 70mph. Without any forewarning, the vehicle began to violently shake. Just as before, the skid warning light simultaneously came on, followed by the check engine light came on, and then the oil pressure guage started bouncing around. As there was heavy traffic on the interstate, the failure created a very dangerous situation for us as we tried to maintain our lane, and stay in control of the vehicle until which time we were able to safely maneuver to the side of the road. The vehicle was again towed to Vann York GMC in Asheboro, NC. (invoice attached) On December 3, 2025 we received a call from VannYork GMC saying that the vehicle repairs were complete. It had been in their repair shop for 4 months. This repair began with lifter and camshaft replacement. When this repair was unsuccessful, they decided that the vehicle needed a 'new' rebuilt engine. Since GMC has not offered any assistance with the expense of this new re-built engine, we will have to satisfy the $12,000 bill when we pick it up. After experiencing two very dangerous episodes, we are happy that we did not wreck, but certainly, this not the situation we expected from a high-end vehicle with only 76,169 miles on it.

  At stop light vehicle began to sputter, run rough, and make noise. I was less than a mile from my home, no check engine light on. I turned the vehicle off, used a scanner to have codes P0106 and P0506 show. I had vehicle towed to Complete Car Care. Misfire on multiple cylinders, 3 push rods bent, one valve spring broken. The right Cylinder head assembly had to be removed and replaced with 8 new push rods, 8 new lifters, gaskets, seals, and valve spring. Total cost 3304.79, the vehicle only has 69,801 miles on it. In addition one of the rear tail lights has a known issue (found out on google), intermittently goes out, was never notified. I took the car to Jim Hudson GMC to be told it would cost 475 plus tax because I did not come in early enough even though it is to be warranted up to 70,000 miles. I am greatly concerned that this engine has the same manufacturing defects of the current recall and extended recall for the GMC Yukon Denali engines.

In addition the rear tail light has been sporadic on and off, GM was to replace up to 70,000 miles. When I took it to them they stated the time limit had expired, yet I had not been informed until I did a google search. GM requesting 475 plus tax. I am concerned my vehicle has the same manufacturing defects as the GM motors being recalled with total engine failures.

  DRIVING MY VEHICLE IN WINTER WEATHER CONDITIONS, IN AUTOMATIC 4 WHEEL DRIVE OPTION. I TURNED THE CORNER BY MY HOUSE ON A CITY STREET GOING NO MORE THAN 7 MPH. I WAS TAPPING THE BRAKE AS I TURNED. I'M NOT SURE WHAT REALLY HAPPENED AS I WAS BRAKING (THE BRAKES SEEMED WEIRD; KIND OF LIKE ABS), BUT MY VEHICLE SLID AND HIT THE CURB ON THE STREET I WAS TURNING IN. THIS IS KITTY CORNER FROM MY HOUSE. MY RIGHT REAR TIRE DROVE UP ONTO THE CURB AND HALF WAY ONTO THE SIDEWALK, BEFORE GOING BACK OFF. I DROVE RIGHT INTO MY GARAGE FROM THERE AND THE VEHICLE WAS MAKING A WEIRD NOISE. MY WHOLE TIRE/WHEEL WAS BENT AT AN ANGLE WITH THE BOTTOM GOING INWARD. THE TIRE AND WHEEL DID NOT HAVE ANY DAMAGE. THERE WERE SCRAPES ON THE HUB CAP. WE TOOK THE TIRE OFF AND SAW THAT THE HALF SHAFT HAD SNAPPED RIGHT IN HALF. AFTER LOOKING AT THIS, THERE WAS BUBBLING AROUND IT. IT SEEMS THAT THE WAY THIS WAS MANUFACTURED IS NOT IN ANYWAY SAFE. THANKFULLY, I WAS RIGHT BY MY HOUSE. IF I HAD BEEN GOING ANY FASTER IN WINTER WEATHER CONDITIONS, WHO KNOWS WHAT COULD HAVE HAPPENED IF I SLID INTO SOMETHING ELSE GOING FASTER. I AM GLAD MY WIFE AND KIDS WERE NOT IN THE VEHICLE. I WOULD THINK THIS WOULD BE COVERED IN THE POWERTRAIN WARRANTY; 5-YEAR/60,000. ONE PERSON WITH GM STATED IT WAS INCLUDED WITH THE 3-YEAR/36,000 OPTION. OUR MILEAGE IS BARELY OVER AT 36,352. THE DEALERSHIP I TOOK IT TO, STATED THEY WILL NOT BUDGE OVER 36,000 MILES. I BELIEVE THIS IS A HUGE SAFETY ISSUE AND THAT IT SHOULD BE COVERED NO MATTER WHAT! THIS SHOULDN'T HAVE HAPPENED WHEN THERE WAS NO DAMAGE AT ALL TO THE TIRE. HOW COULD SOMETHING LIKE THIS JUST SNAP IN HALF? IT JUST DOESN'T SEEM RIGHT! THIS VEHICLE WAS EXPENSIVE AND APPARENTLY BUILT VERY CHEAP!!! WE JUST HAD A RECALL FIXED TOO! WE HAVE ONLY PAID TO GET IT TOWED TO THE NEAREST DEALERSHIP, WHICH IS IN THE NEXT TOWN OVER ABOUT 15 MILES AWAY. MY PICS ARE MORE THAN 5MB. THEY ARE 7+MB.

  Not sure if this is the correct raea to notify regarding this incident. I had windshield replaced by Safelite Auto Glass in Cadillc Mi.After the service the technician said he calibrated everything and all is fine. Upon my initial driving after the windshield service the vehicle engine light was flashing and the display was telling me the advanced collision and lane departure warning systems were inoperable. Additionally the vehicle would not accelerate. The vehicle could not be driven safely. I contacted Safelite in Cadillac Michigan the next morning and was initially told the warnings have nothing to do with the service they performed and they do not have to do anything to help me. The manager advised that they ran 3 scans with their equipment and all scans came out good. The manager is saying that confirms everything was OK. I see that as an admission of something being wrong since the technician ran 3 scans. Why run additional scans if all is good. What he was seeing is that the vehicle was displaying warning lights and was not running properly. That is why he kept running scans over and over. Even after 7 scans now they are still saying it's not their problem. Obviously their equipment is incapable of calibrating the new windshield to the vehicle. Additionally they have caused a problem within the engine control module by hooking up faulty electronic device. The vehicle is inoperable. Additionally Safelite knows that they are incapable of performing windshield replacement on this vehicle. The technician no more than left my driveway and I received a text from Safelite saying: "Modifications to your vehicle may cause your advanced safety systems to not function a intended" That is admission thjat Safelite knows they are incompetent in this matter. The windshield is in of the most important safety feature in a vehicle. It is unacceptable the an industry leading automotive aftermarket company is continuing to operate this way. Please look into this.

Metal within the lamp vibrates loose and cause the brake lamp to fail - thus resulting in no BRAKE Lamps illuminating at braking. This would be the second time this issue has occurred in 4 months, with the previous repair occurring rear drivers side and logged with NHTSA for this issue under 11436519.

  Engine failure 6.2L cylinder failure. Recall already in effect for other years. But it seems that it is needed to be expanded. I had to do a complete engine replacement and all oil related components. Metal was found easily in the oil and oil filter. I was luckily in a parking ramp when it happened so I did not crash. I was already driving for 45 minutes prior on the interstate. Could have been very dangerous at high rate of speed.

  Noting that prior to this we only had one issue with transmission and we did the flush and it did fine for several thousand of miles. Fast forward to a few days ago. As I was driving down the highway I came to a stop at the red light. Once it was green and I pressed on the accelerator with my foot per usual. And it did not move it pushed the gas peddle and nothing at all happened. I was stuck in the highway could not move until I’m assuming the transmission finally shifted jarring my entire car and it allowed me to get to a safe place at 20 miles an hour max. Keep in mind I was in the middle of the highway not knowing what was happening. With my precious babies in the car. Thanking God we were not injured. This problem is so common and notorious among GMC Yukons 2017 year models. It’s saddening that now I have a car note on a car that will not go. Transmissions are back ordered who knows when I can have my car back this economy is horrible trying to stay afloat. And now we have a vehicle that won’t drive and no time forks of when it can drive. This needs to be addressed asap. Other people are dealing with the same things and GMC need to make this safety concern a thing of the past. Make a recall.

  We were on the freeway with my 4 small children. The freeway speed is 75 mph. The car had been jerking and hard shifting for over a week and I had it scheduled with a mechanic. As we were driving on the freeway, it lost total power as cars were going to the left and right around us. I was barely able to get it to the side of the road without being hit. This could have been tragic! I took it to the mechanic and the transmission is shaving a lot of metal (that was in the bottom of the pan). I have had to pay to have a whole new transmission redone. This is absurd with a car that is only 4 years old.

  UNKNOWN 4 times in the past 6 months, while parking the vehicle (turning into a spot, left or right) or slowly turning to pull up to a security code box, the car completely begins to lose power in drive, and has lost power while in drive twice. The dash begins to flicker to the point that you can't decipher which error codes are showing up. Most recently, the Trailer Brake Service message was on before it died. We were not towing anything, did not have tow mode on, or anything like that. The parking sensors were on for all these instances...regardless if we were parking or not. I can't confirm if that is the issue or not. It was pretty dangerous when I was pulling into my parents driveway along a busy road when the car did this before I was completely off the road...with my 3 young children in the back 2 rows. I know the battery is new. I did have the dealer look at the brakes about a month ago, because I felt they were soft. They said they were fine. They and myself checked the reservoir for brake fluid low. Was in normal range. Starter was replaced in March time frame. I feel this is related to the factory trailering system wiring harness or something.
