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 and make noise, I was very close to my home, no engine light on. Upon turning vehicle off and using a code reader codes P0106 and P0506 was on scanner. I had vehicle towed to Complete Car Care. Mis fire on multiple cylinders. Vehicle has 69,801 miles. 3 push rods bent and I 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. Cost was $3304.79. 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.

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.

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.

The engine developed a ticking noise which turned out to be bad lifters and bent lifter rods, and a bad valve lifter oil manifold.

drivers side tail light flickering and sometimes not working a $900+ cost! I issue with right hand side when suv has 32k miles, seems like this is an ongoing issue, luckily it was still under warranty the 1st time. The AC condenser when out in April, also an know issue with the Yukon, they wanted to charge me $1500 to repair, I was able to find someone to do it for around $600, now the outlet and usb ports seem to not work. I also had an issue with the braking system , dealer couldn't figure it out, I finally found someone to repair it, $500 fix. For what I paid for the Yukon, you would think they would use top of the line parts!

There was a pump in the heart of the transmission. The dealer said told me that was leaking fluid. Apparently this was a faulty hose within the transmission which leaked fluid in the transmission. Therefore, my transmission died. This was a severe I could have been a very dangerous situation if my kids had been in the car. I’ve had to pay almost $8000 for the transmission to be fixed and yeah I see that on the line there was some sort of recall but my dealership is saying there was not. I bought this car brand new and I’ve had it for seven years. I’ve never had an issue with the transmission on any of my vehicles ever.

Car has 100k miles on it. At 59k the fuel injectors went out and needed to be replaced. Then the transmission went out and needed to be replaced, then the front differential needed to be rebuilt, also had to replace the struts. Now the lifters are going out and that, plus likely the camshaft, need to be fixed. Total costs for all the above is close to $20,000. If not fixed these problems could easily result in catastrophic engine failure while driving leading to personal injury and death. I see that there is a class action lawsuit for the latter.

The 'active fuel management/displacement on demand' lifters failed and caused the engine to run very poorly with a significant lack of power. This occurred while driving and could have caused a crash before I was able to get off the road and out of the way of traffic. The problem was diagnosed and confirmed by an independent repair shop. The vehicle had to have the camshaft and all valve lifters replaced, as well as several valves that were damaged in the failure. The total cost to repair was just over $9000. The failure also caused the catalytic converters to become clogged, resulting in even further loss of power from the engine. There were no warning lamps or symptoms prior to the failure. It occurred suddenly as I was driving down the road. Searching online reveals this seems to be a common problem with GM 5.3 and 6.2l engines from 2010 onward. GM is aware of the issues and refuses to assist in any way. Their only response is that the vehicle is "Out of warranty". The failure is caused by a design defect in the AFM/DOD system that starves the lifters of oil, resulting in lifter failure and damage to the camshaft and valves.

I have a 2017 Yukon XL with 80,000 miles on it. Last year I was driving on the highway with my kids when it began to lose power and failed to accelerate. The issue was in the engine and I had to replace the entire engine for $8000 because it was barely past the warranty. Now one year later the car began to jerk and not shift while on highway and it is the transmission that is going to be replaced for $6000. The 2017 Yukon XL is a lemon and very dangerous for drivers. I spent $45k and should not be replacing the engine and transmission withing 6 years of it's age. Reading online these are common issues putting lives at risk.

When accelerating the car starts bucking, after driving some more shakes like going over speed bumps.

Driving towards the bank and suddenly the truck turned off … no warning nothing it turned off while operating .

CAR STRUGGLED TO START WHEN I STARTED IT. IDLE WAS/HAS BEEN REALLY SHAKY. ENGINE LIGHT CAME ON. I GOT A DIAGNOSIS FROM 2 COMPANIES FOR MY ENGINE. BOTH SAID I NEEDED TO REPLACE ALL 8 FUEL INJECTORS. GMC HAS AN EXTENDED WARRANTY TO COVER THESE ISSUES, BUT IT IS NOT AVAILABLE FOR MY STATE OF UTAH. HERE IS THE CODE FOR REFERENCE FOR YUKON #N182198000. MY CAR IS A YUKON XL 2017 THAT NEEDED FUEL INJECTORS AT 85,000 MILES! HOW IS THIS OKAY? THE REPAIR COST $1,990.28. THE POWER TRAIN WARRANTY HAS BEEN CHANGED FOR 2016 AND 2017 GMC VEHICLES SO THAT IT IS NOW 60,000 MILES OR 5 YEARS. MECHANICS HAVE REPORTED THAT GM HAS CHANGED THE WAY THEY ARE BUILDING ENGINES IN ORDER TO REDUCE COSTS, BUT IT APPEARS THAT CONSUMERS SUCH AS MYSELF ARE BEARING THE BRUNT OF THE COSTS. I WOULD APPRECIATE IF THE EXTENDED SERVICE WARRANTY COULD BE EXTENDED TO ALL STATES IN THE U.S. VS. THOSE WHO HAVE MANDATED IT BECAUSE OF LEGISLATION OR LEGAL ENFORCEMENT.
