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.

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.

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.

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.

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.

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

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.

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.

UNINTENDED SURGE OF ACCELERATION. WILL HAPPEN RANDOMLY ABOUT ONCE A WEEK WHEN UNDER SLIGHT ACCELERATION. IT FEELS LIKE THE ACCELERATOR GOES FULL THROTTLE FOR ONE SECOND, CAUSING A HUGE SURGE OF ACCELERATION, ALMOST PLOWING INTO THE CAR IN FRONT OF US MULTIPLE TIMES. THE LAST TIME IT HAPPENED WHILE IN REVERSE. DEALER EXAMINED THE CAR AND SAID THERE ARE NO CODES STORED IN THE COMPUTER AND COULDN'T REPLICATE THE PROBLEM. WE GET THE CAR BACK TOMORROW AND MY FILE DRIVES IT WITH OUR 4 KIDS, SO THIS IS VARY SCARY (FOR THE SAFETY OF OUR FAMILY AND OTHERS ON THE ROAD). DEALER SUGGESTED IF WE DON'T TRUST THE CAR, WE CAN HAVE CAMERAS INSTALLED IN THE CAR TO CAPTURE THE PROBLEM SO WE CAN SHOW THEM. WE HAVE VERY LOW CONFIDENCE IN THIS CAR AS IT IS DANGEROUS TO DRIVE. THE FIST TIME WE NOTICED THIS WAS IN THE AM, SO THE ENGINE WAS STILL COLD. STARTED ACCELERATING SLIGHTLY DOWN OUR RESIDENTIAL STREET AND THE CAR WENT TO FULL THROTTLE ON IT'S OWN FOR ABOUT 1-2 SECONDS (RPMS SKY ROCKETED). THE SECOND TIME WAS ABOUT A WEEK LATER WHEN MY WIFE WAS DRIVING THE KIDS TO SCHOOL IN THE MORNING (AGAIN WITH A COLD ENGINE). SHE PULLED OUT OF AN INTERSECTION AND THE HEAVY SUV WENT TO FULL THROTTLE ON ITS' OWN AGAIN, ALMOST CAUSING HER TO LOSE CONTROL. THE PROBLEM PRESENTS ITSELF ABOUT ONCE OR TWICE A WEEK. THE LAST TIME SHE WAS BACKING OUT IN REVERSE WHEN THIS OCCURRED, CAUSING HER TO ALMOST CRASH INTO SOMETHING. DEALER CAN'T FIND THE PROBLEM BUT THE PROBLEM EXISTS. THE ONLY THING IN COMMON BETWEEN ALL OCCURRENCE IS THAT THE ENGINE WAS COLD, THE AC WAS ON, AND THAT WE WERE UNDER LIGHT ACCELERATION WHEN THE SYMPTOM PRESENTED ITSELF.
