2019 GMC YUKON XL

ENGINE

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.

POWER TRAIN

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

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.

ENGINE AND ENGINE COOLING

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.

VEHICLE SPEED CONTROL

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.

UNKNOWN OR OTHER

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

FORWARD COLLISION AVOIDANCE: WARNINGS

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)

ENGINE

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.

ENGINE

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.

ENGINE

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.

ENGINE

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.

ENGINE

Transmission went out at 100,000 miles, exactly.

ENGINE

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)
