2019 GMC YUKON XL Recalls, Complaints & Safety

P0304 and P0306 misfiring and compression on both cylinders is 0. Both lifters have broke and collapsed. It started with a noise, once checked by the mechanic, we were told the lifter was going bad, before we could get it repaired it completely broke and that is when the check engine light came on and went off repeated times. At this time it is pouring out black smoke when driving and must have a complete engine replacement. The replacement work has been quoted for $10479.57.

Crash 3 injured

I suddenly noticed a noise coming from the engine that sounded like a noisy lifter and stopped using the car after hearing it. The next day I called Circle Chevrolet to check and verify if they could check the car and do any work required under the CPO Warranty. They advised that they could since they were part of the GM Family and could do any work required under the CPO Warranty. I then arranged to have the car towed to Circle Chevrolet to prevent any further damage, that was on Oct 20, 2025. The CPO Warranty was due to expire on Oct 27, 2025 due to time, not mileage. The dealership advised that the vehicle would need to be examined by one of only 3 qualified mechanics in their shop who could do this evaluation and determination if the issue(s) were covered under the CPO Warranty and it would be about 3 days before they could have one of their 3 qualified technicians check the car. The Service Adviser called me back on October 22nd, 2025, and advised that Cylinder 5 had noisy lifters and that they would be changing out the engine with a newly rebuilt engine, all under the CPO Warranty. The Service Adviser said it would take 3-5 days to get the replacement engine in and then about 2-3 days to replace the engine. However, less then 24 hours after getting my car back, the check engine light came on, which was not on when I had the car towed to the dealer. They said the catalytic converter needed to be replaced and said it would be ~$6000. They refused to cover the replacement even though the catalytic converter was damaged due to a combination of the engine problem/defect and the testing and installation work performed by the dealer. I reached out to the dealer and GMC and they refused to address the issue and would not provide an itemized estimate to replace the catalytic converter and refused to return my phone calls I made to both the Service Adviser and Service Manager. The GMC representative I spoke to refused to address the issue as well.

The transmission is shaky, Lower gears the truck seems to fight it way into the next gear, I feel this is happening around 3 to 5 gears. One garage told me the power converter was failing. I changed the transmission fluid and filter and it got better, but sill, this is an expensive truck. This is power train, this should be covered to 100,000 miles.

The contact owns a 2019 GMC Yukon XL. The contact stated that while driving approximately 30 MPH, there was a misfire in the engine, with a ticking sound coming from the engine compartment. There was no warning light illuminated. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The contact was referred by the manufacturer to the NHTSA Hotline for assistance with having the VIN linked to NHTSA Action Number: PE25001 (Engine and Engine Cooling). The approximate failure mileage was 104,389.

Camshaft/Lifter broken and need replaced

Engine began knocking noise at around 150k miles, noise became faster with throttle speed. Brought in to repair shop, mechanic confirmed connecting rod failure, suggested replacing engine. Replaced engine as suggested.

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. The contact discovered information of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not available. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 127,000.

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.

The engine had catastrophic failure McCluskey Chevrolet Kings Auto Mall said it needs an engine replacement that has a blown engine. There is currently a recall on this particular 6.2 l87 engine from 2019 to 2024 but my vehicle for some reason isn't included but it's got the same problems as all the other ones

The contact related the failure to an unknown recall. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

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.

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.

Engine Knock, possible piston rods bent. oil in cylinder. cylinder has not enough compression. No safety issues, was able to drive to mechanic without harming myself or others. this is the second vehicle in my family to have lifter or rods issues leading to major engine work. Check engine light came on after the vehicle began to misfire.

The contact owns a 2019 GMC Yukon XL. The contact stated while driving 60 MPH, there were abnormal loud sounds coming from the engine. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with crankshaft or lifters failure. The contact related the failure to NHTSA Action Number: PE25001 (Engine, Engine and Engine Cooling). The dealer was contacted and provided an estimate for the repair because the VIN was not under recall. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 106,000.

Driving down the interstate and engine gave out, started shaking, and started losing speed. No warning, in the middle of the night with two young kids in the car. Sat on the side of the highway in the pitch dark. 2 days later truck was towed but the GMC had no one to look at it. Had it towed again and that GMC dealership said it was the engine and they see it all the time with that year/make/model. $16,000 for new engine. Contacted GMC and they stated that year is not included in the recall. Research this issue on google and most owners of the same year/make/model have the same issue with no help to solve the problem.

The contact owns a 2019 GMC Yukon XL. The contact stated that while attempting to start the vehicle, there were abnormal sounds coming from the engine. The contact stated that the check engine warning light illuminated and started flashing. A dealer was contacted. The vehicle was towed to a dealer where it was diagnosed and determined that part in the engine had failed, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure via email. The failure mileage was 64,747.

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.

Diagnosed as in catastrophic engine failure

Reporting engine failure with my 2019 GMC Yukon XL. Reporting engine failure after 106,500 miles. Yukon was properly functioning and well cared for with frequent oil changes and tire rotations. On [XXX] I was driving home with my [XXX] daughter coming back from her dance recital on [XXX] at [XXX] in Minnetonka, MN when the "Forward Collison System Unavailable" warning notification came present on my dash. The vehicle started to sputter and an abundance of smoke was coming out of the rear exhaust. Fortunately, I was able to make it home safely. I brought the car in the following day and it was diagnosed that the engine failed and complete repair of camshaft, cylinders, engine coolant lines and oil pans would need replacement. I did notice that the vehicle years 2021 to 2024 are currently under recall for similar issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This vehicle has left my family along side of a high twice. First time from lifter failure the second time from bearing failure. The bearing failure caused the vehicle to shut off and made for an unsafe pull off of a major highway. Both times this has happened with no warning till it happened. Lost of power with the check engine light coming on at the same time. No warning of any issues till it was to late a broke down. This could have been tragic to my family the second time around when complete shut down on an interstate highway why driving in heavy traffic. WITH NO WARNING boom shut off!! Every gm/chevy dealer I been too even say it’s been an issue and don’t understand why gm has not fixed the problem. These repairs alone cost us over 18000 out of pocket.

The contact owns a 2019 GMC Yukon XL. The contact stated while driving at an undisclosed speed, the vehicle made an abnormal banging sound. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with catastrophic engine failure. The dealer determined that the engine needed to be replaced. The vehicle was not repaired and was taken back to the residence. The contact related the failure to NHTSA Action Number: PE25001 (Engine, Engine and Engine Cooling). The manufacturer was not notified of the failure. The failure mileage was approximately 110,000. The VIN was not available.

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.

Catastrophic engine failure to the GM 6.2L engine. Mechanical issue - cam or crankshaft came apart. Safety to myself and/or others as I was driving on the road in traffic when the issue occurred and had complete loss of power. I was able to avoid traffic and get the SUV to the shoulder of the road. The issue was confirmed by my auto service provider. No warning lamps or messages prior to failure. Once failure occurred, the check engine light started to blink.

There was a problem with the catalytic converter that I was not aware of when I purchased the vehicle. There were no issues with performance for a few days until the engine began misfiring on the interstate and it forced me to pull over during heavy traffic. This was all in a week and the dealer has refused to take any responsibility despite being a Chevy Certified Dealer. I am now getting the vehicle repaired by my local mechanic due to the need for this vehicle. I have made General Motors aware of the situation.

Transmission went out at 100,000 miles, exactly.

See attached document for complaint.

Total engine failure with no warning. Vehicle has approximately 106,000 miles. While driving on Monday [XXX], the car began shaking violently and the engine light began flashing. Fortunately I was only about a mile from a GMC dealership, so I pulled into Rice GMC Buick in Knoxville, TN. They informed me that there was a catastrophic engine failure and that a complete replacement would be necessary at a cost of $15,000 dollars. I live 100 miles away in Chattanooga, TN. I understand that cars experience some level of wear and tear, but a total engine failure at just over 100,000 miles when the car has been serviced at all regular intervals is very unusual. I recommend my case be referred to active investigation #PE25001. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

GMC engines are faulty and puts people at risk when they malfunction. The first time the vehicle lost power, It was spitting and sputtering as i was driving with my family in the car. The vehicle Left us sit along side the road of a major highway in freezing temps. The lifters malfunctioned costing 5000 dollars in repairs. Once again started having loss of power and the vehicle shut completely down while driving down the road with my family in it. So no engine means no power steering an etc . Again left us sit along side the road. The main bearing has went in the motor. Now costing us 16,000 in repairs For new engine. Now we are at the cost of 21,000 in repairs. This is a known issue with the v8 engines a yet GM has done nothing to fix or compensate people for their loses. I’m stuck with this vehicle now cause I’m so upside down at this point it’s disgusting. Also sad an auto manufacturer doesn’t NOT stand behind their product as it puts people and their family’s at risk. They NEED TO BE held accountable for this issue as thousands of people have had this issue. I don’t have the other repair bill on me at this time do to the car is in the body shop from a deer accident. But I do have one an can provide it at a later date if needed. Thanks

The contact owns a 2019 GMC Yukon. The contact stated while driving 55 MPH, and approaching a red light, the brakes failed to operate upon the depression of the brake pedal. The brake pedal was firm while the contact steered the vehicle off the shoulder of the road. Due to the failure, the contact drove through the intersection and allowed the vehicle to coast to a complete stop. Upon restart of the vehicle, the "Brake Assist" message flashed on the instrument panel. The contact's husband was called to the scene and later drove the vehicle to an independent mechanic. The mechanic inspected the vehicle and discovered that the vacuum pump had failed. The vehicle was repaired by the mechanic. The dealer was notified of the failure and offered to inspect the vehicle; the dealer then referred the contact to the NHTSA Hotline to report the failure. The manufacturer was notified of the failure but offered no assistance. The failure mileage was approximately 131,600.

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.

The contact owns a 2019 GMC Yukon XL. The contact stated that while reversing out of the driveway at approximately 2 MPH, the vehicle stopped moving. The contact depressed the accelerator pedal and the vehicle only revved. The contact stated that she was able to move the gear shift lever, however the vehicle was not responding in any gear. The contact stated there was no warning light illuminated. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the transmission had failed and needed to be replaced. The vehicle was not repaired.

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).

My vehicles Electronic stability control is activating randomly. This issue started a few years ago and has increased in frequency. We will be driving at speeds between 50-75 mph in dry conditions and it will randomly activate which has almost caused us to lose control of the vehicle. No mechanics have been able to figure it out. I did some research and saw there was a vehicle recall issued for 2019 GMC Yukons Electrontronic Stablilty Control system, but for some reason it does not cover my vehicle. The GM recall number is N192261050. The description of the issue matches exactly what is happening. I called GMC and issued a complaint and also have setup a dealership to fix the issue. I don't believe i should be responsible for paying the cost of the repair since other 2019 GMC Yukons were recalled for this issue.

Steering will all of a sudden feel disconnected. Feels like truck is sliding, till I move the wheel, then it feels connected again. Very weird feeling. This only seems to happen on the highway at highway speed. Witch is the part that worries me. This happens at least once every time on on the highway.

it's been a known fact and on social media there has been many complaints, why is there nothing being done. this vehichle has a water or moisture problem which goes to the electric connectors and makes the vehichle go in to derate mode and only code it throws is peddle position sensor. which I have changes, and still no fix, as other connectors that are going to the electronic board removed, and it has corrosion. this is clearly a safety risk and it literally puts in a mode where a truck is not drivable.

Crash

This car had catastrophic engine failure due to the lifters, push rods and camshaft. This car make and model and engine type is notorious for these specific parts to malfunction. This could have left myself and my children stranded on the interstate. The vehicle has been inspected by a certified master technician with ASE training. They confirmed that these parts are a common issue with these cars.

The contact owns a 2019 GMC Yukon XL. The contact stated while driving at an undisclosed speed, he heard an abnormal sound coming from underneath the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a general failure with the transmission. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the dealer, who again diagnosed a general failure with the transmission, and informed the contact that the transmission needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was not notified of the failure. The failure mileage was 65,000.

Service Trailer Brake System keeps coming on while driving. Dealership says nothing wrong although they replaced fuse. Still happening. Only thing that seems to work is pulling off road and restarting vehicle. That is only a,temporary "fix". Comes back a few days later. This is a safety issue as 1) distracts me while driving 2) I pull an 8,000lb travel trailer with the vehicle.
