  The contact owns a 2019 GMC Yukon XL. The contact stated that while driving approximately 68 MPH, the vehicle vibrated abnormally, with a knocking sound coming from the engine compartment, with the check engine warning light was illuminated. The vehicle was taken to a certified mechanic, who diagnosed the vehicle and determined that lifter #7 had failed and needed to be replaced. The contact stated that all the lifters were replaced. The contact stated that approximately 5 days later, on October 2, 2025, while reversing, there was a burning odor with black smoke coming from the exhaust pipe. The vehicle was towed to the mechanic and was diagnosed with coolant intrusion into the engine. The contact was informed that the engine needed to be replaced; however, the warranty only provided the replacement of 2 head gaskets. After 7 days of having the vehicle, while driving approximately 68 MPH, the vehicle started shaking with the check engine warning light illuminated. The vehicle was also idling roughly. The vehicle was towed to the mechanic and was diagnosed with fuel pump failure. The fuel pump was replaced; however, the vehicle was idling roughly, and there was an intermittent misfire in cylinders #1 and #6. The dealer was unable to identify which cylinders needed to be replaced.

• 11/11/2025· POWER TRAIN

  The vehicle experienced a lifter and valve train failure within the warranty period, as addressed in GM TSM MC-10209953. This failure can cause sudden engine noise, loss of power, and potential engine seizure while driving, creating a serious safety hazard for the driver, passengers, and others on the road. The component failure is reproducible and has been confirmed by a repair shop; it is available for inspection upon request. An engine rebuild was completed just after the warranty expired, and the manufacturer has denied warranty coverage and refused to address the issue. Prior to failure, no warning lights or messages indicated a problem, meaning drivers have little to no warning before a potentially catastrophic malfunction. Because this is a documented issue affecting multiple vehicles and the manufacturer is refusing corrective action, this defect presents a clear risk to public safety. I urge NHTSA to investigate this matter, determine whether a safety recall is warranted, and require the manufacturer to address this known defect to prevent accidents and injuries.

• 11/09/2021· STEERING

  Multiple times upon starting my Yukon I get a message on the dash that states Power steering disabled drive with care. I have no power steering until the computer has enough time to reset itself, usually about 15 min. This issue has been confirmed at our shop with the code being for the power steering. We have had it into the dealership and they found the same code but were unable to get it to recreate for them. It is not something that happens every day so I would have to leave it with them for a long period of time and that is not an option. This started happening within a couple weeks of buying the vehicle. It started for me in March 2020, with less than 17K miles on the truck.

  The V8 engine on our family's 2019 GMC Yukon Denali XL check engine light came on and began ticking while taking our daughter to college in Montana. The dealer informs us the engine has probable lifter failure and will need to be disassembled to diagnose additional issues. The estimated repair costs are from $3,000 to $10,000+, may require a new engine, and we will be without the vehicle for almost two months. We are incurring additional costs such as lodging, airfare to fly home, costs for an additional car, and storage for a travel trailer that must remain behind. The warranty on our vehcle expired last year. The vehicle has been consistantly serviced at our local dealer. Research and discussions with other GM customers inform us this is a known issue for our year and that a recall was issued for vehicles for 2021 to 2025.

  I have 98,000 on my Yukon XL Denali and I have a crack in the piston block as I was told by the dealer. I have an Endurance Car Warranty on the vehicle and the vehicle has been at the dealers since [XXX]. The warranty company is giving the dealer the run around where they have torn down the motor already twice to prove to them that there is a crack. Plus, there was no warning signs other than it not running smoothly as it has been and that is why it went to the shop. Nothing should be happening to this motor at 98,000. The vehicle is presently at Palm Chevrolet in Ocala, Florida and Scott Kelly is the service manager. Can you please give me some advice.

  2019 GMC Yukon XL. Purchased pre-owned from a dealership in July 2023. This month, August 2025, my transmission has failed. Apparently this defect is notorious for this particular year of GMC Yukon XL. There was a lawsuit against GMC but it was closed in June 2025. The issue is real and widespread and GMC should ABSOLUTELY be responsible. There’s no reason a six year old vehicle should require this extensive repair.

  The air conditioning system in my vehicle failed in April 2025. My dealership service department diagnosed the problem as a refrigerant leak requiring the compressor to be replaced. I had the $2400 repair made replacing both the compressor, condenser and the a/c system was charged. 2 months later, I am having the same issue again - failure of the a/c system due to a refrigerant leak requiring the condenser to be replaced. A quick Google search identifies a recall on the 2019 Yukon XL noting a "refrigerant leak due to thermal cycling". Though this is the precise year, make, model and distinct problem that I am experiencing, my specific VIN has not been included on the recall. We are in the height of summer, currently experiencing temperature that feel like 104-107 degrees in East Tennessee thus is has become a safety issue for myself, 4 children and husband to travel in our primary/only family vehicle. I find it unbelievable that a vehicle of this caliber has a basic (air conditioning) system failure after 6 years; however, it is incomprehensible to spend $2400, have it repaired, know there is a recall for the precise vehicle and concern, have it fail again and be expected to spend another $2400 because my specific VIN is not included. It is simply preposterous. I am requesting that my specific VIN be included on this recall, please.

  GM vehicles manufactured between 2015 – 2019 equipped with GM’s 8-speed transmission are equipped with a defective transmission design of GM’s Hydra-Matic 8L90 transmission or Hydra-Matic 8L45 transmission, which causes vehicles to suddenly lurch forward, shudder, and experience significant delays in acceleration. GM not only knew about this pervasive issue but developed a fix for it in 2018 – namely a transmission flush it calls Mod1a. However, GM made the business decision in 2019 to forgo recalling all impacted vehicles (approximately 2 million) to receive this flush, which would have cost GM about $305 per vehicle for a total $592 million, and instead decided to limit the flush to only unsold Cadillacs and trucks in certain states where it expected customers to complain within their warranty. Furthermore, GM never alerted existing customers of the issue or the fix and only addressed the issue if the customer was under warranty and complained about the shudder. GM marketed and sold these 8-speed automatic transmission vehicles as having “world-class performance,” lightning-fast and smooth shifting, along with improved fuel efficiency, and instead sold defective vehicles.” These conditions make it difficult to safely merge into traffic or back out of a garage/driveway. Even more troubling, the transmission defects cause the vehicle to delay downshifting and decelerating when the brakes are depressed. The affected vehicles include Chevrolet Silverado (2015-2019); Chevrolet Colorado (2017-2019); the Chevrolet Corvette (2015-2019); the Chevrolet Camaro (2016-2019); the Cadillac Escalade and Escalade ESV (2015-2019); the Cadillac ATS, ATS-V, CTS, CT6, and CTS-V (2016-2019); the GMC Sierra, Yukon, and Yukon XL, and Yukon Denali XL (2015-2019); and the GMC Canyon (2017-2019).

The sad thing is when I pulled up to the dealership and told the sales manager and shop manager my problem they just shook their head and said it won't be good and that they have had to replace a lot of them, so many that they keep the transmission in stock like wiper blades.

I always change oil on regular intervals and there were no check engine lights and engine continued to run fine with no loss of power or ticking changing. It was our only vehicle so we had to continue to drive that day. Wife was driving and said vehicle shuddered and started sounding funny and check engine light came on she was able to drive back home. Now ticking is worse with a clucking rattling sound now coming from oil pan. After some internet searching it very much sounds like issues many others are having with the 6.2l GM engine.

  At 70 mph the adaptive cruise control system applied the brakes hard enough to engage the abs system even though my lane of travel was clear. There was a car on the exit ramp to the right applying their brakes not in my path that I believe my vehicle picked up. There were several vehicles behind me and it almost caused an accident. There needs to be a way to disable the adaptive cruse on this vehicle for safety concerns. This has happened to me on multiple occasions and I reported it to the General Motors hotline with absolutely no feedback on the issue.

  Vehicle began idling rough then check engine came on. Acceleration would then vary while driving. Took to GM dealership and they said lifters, head gaskets and cam shaft are bad. The charge to repair is $7,736. Saw GM just did a “voluntary “ recall for this same issue on year models starting 2021-2024. 2019 year should be added as this is a costly repair.
