2023 GMC Yukon Xl Engine Problems

This is an ongoing problem from date of purchase, before the normal oil change time the low oil light comes on. When i check the oil dip stick it is in fact low. I have to add at least 2 qts of oil to get it to the right level. Time frame would be at least once every 2 months under normal CA driving conditions. Also does have a rough idle and noise that sounds like the motor is going to come apart on startup. I have takin it to the dealer, they performed consumption test and checked the motor recall. The dealer told us that our motor passed the recall inspection, made the changes, oil, oil cap, etc. Then told us it passed the consumption test. Since then I still have to add oil between oil changes. We were told by the service tech that even if the motor is bad, there is no replacements at this time and the vehicle would just sit at our dealership until we can get a replacement. No one has been hurt at this time. I'm just waiting for the motor to lock up. The vehicle can be inspected upon request. The only warning light that comes on is the low engine oil warning.

I had the recall remedy of the v8 completed. They said it only required thicker oil which now lowers fuel economy and costs more for oil changes. After the recall, the engine still makes a knocking sound

Incident

Aug 13, 2026

I am reporting a severe, recurring, and life-threatening manufacturing defect involving a sudden, catastrophic loss of motive power at highway speeds on the interstate. This vehicle has suffered two identical valvetrain failures that placed my passengers and nearby motorists in extreme danger. Incident 1 (Approx. 40,000 miles): While traveling at high speed on the interstate, the vehicle violently shook, all engine warning lights flashed, and the engine suffered an immediate, near-total loss of propulsion. The vehicle was towed to an authorized GMC dealership, where technicians diagnosed a collapsed Dynamic Fuel Management (DFM) hydraulic lifter in Cylinder 3. The lifter bank was replaced under the factory powertrain warranty. Incident 2 (Approx. 77,000 miles): While driving at high speed on the interstate, the exact same vehicle behavior occurred. The engine suffered a sudden, total loss of power, and all dashboard warning lights illuminated simultaneously. Out of absolute necessity and to avoid a catastrophic high-speed collision on a dangerous stretch of highway, the severely crippled vehicle had to be forced through active interstate traffic without proper engine power all the way to my home. The vehicle has since been inspected by a GMC dealership, which has confirmed that the exact same Cylinder 3 lifter has failed a second time. The dealership and the GMC Regional Service Manager are currently refusing to honor the 24-month dealer-installed service parts warranty, demanding an out-of-pocket deposit of $5,000, and denying alternative transportation. GM's failure to permanently remediate this known, systemic valvetrain defect has twice left me navigating a failing vehicle through high-speed highway traffic, heavily compounding the safety risk.

Incident

Jul 20, 2026

My vehicle was taken in as part of the 25v-274 recall. It passed and was given the new oil. It underwent a second oil change using the new oil and before the third oil change at around 46,000 miles the engine was having trouble. I took it in for the oil change and the engine issue. I have barely been told anything but from what I understand I have a camshaft issue and need new lifters. I haven't seen my car in 12 days and have received almost to no updates.

Vehicle shifted into neutral while driving down the highway, extremely dangerous. Would not shift into gear and could not accelerate. Was able to pull over and the vehicle would not restart. Had to have the vehicle towed to a dealership. Dealership found a blown fuse, problem happened again twice and the dealer could not find the problem. This was July 28th, 2026. On August 20th, while in cruise control, slight ringing noise began, then a loud thump, then a loss of oil pressure. Unable to do anything other than pull over on an interstate with my family. Again, very dangerous. The vehicle would not restart and could not be shifted out of park. Had to have the vehicle towed again. Have also had at least 8 recalls on the vehicle. Unbelievably dangerous situations with my family, aside from inconvenient and expensive.

My 2023 GMC Yukon Denali XL, used as a commercial vehicle for my business, experienced sudden and complete engine failure at approximately 70,000 miles with no prior warning. No check engine light, no unusual noise, and no other symptoms. The vehicle had previously been inspected/serviced under GM Safety Recall 25V-274 (L87 Engine Loss of Propulsion) and had been deemed safe prior to this failure. The failure occurred while driving on a two-lane road in Durango, CO. The vehicle lost all propulsion and came to a stop in the roadway, blocking the lane of travel and forcing other vehicles to cross into the oncoming traffic lane to go around the disabled vehicle. This created a serious and immediate hazard to myself and to oncoming traffic. The vehicle was not driveable and had to be towed. The dealer confirmed catastrophic engine failure requiring a complete engine replacement. After the engine replacement, the Morehart Murphy GMC dealership in Durango also failed to properly recalibrate vehicle sensors. They did not reinstall certain suspension components that had been removed for the engine replacement, requiring multiple additional dealership visits to resolve along with recalibration of the air ride suspension. After the replacement I was getting messages that the vehicle was "too low to drive with caution" and "Reduced Acceleration Drive With Care." This vehicle failure occurred during our peak season (June 10-July 2). The vehicle being out of service, I was required to rent a replacement vehicle at my own expense because GM did not provide a loaner vehicle. I estimate loss revenue at $1k/day. When I attempted to raise this issue with GM directly, their response was to submit letter to a P.O. Box, with no other means of resolution or contact offered. Given that this vehicle had already undergone the recall remedy and was represented as safe, this incident is relevant to NHTSA's ongoing investigation into post-recall L87 engine failures (Recall Query RQ26001).

2023 GMC Yukon XL(6.2 liter engine).Engine has failed twice with the first incident being on the interstate and the engine seized without warning with only 38,000 miles. GMC replaced the engine and now the second engine has failed with only 80,000 miles on it. I am told there needs to be a third engine installed and the vehicle is only three years old. If an engine fails without warning this puts everyone in danger. My [XXX] son was in the car when the first engine failed. There is an obvious manufacturer's defect that needs to be addressed before innocent people are injured or killed. The vehicle is currently located at Darrell Waltrip GMC in Franklin, Tennessee. It is not drivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car just died while going 55mph on the highway. Complete shutdown but luckily both the steering and brakes worked. After stopping it wouldn’t start again. I had my three children in the car aged [XXX], [XXX], and [XXX]. It was a horrific experience. GMC did some repairs to the engine that took over two months and then the car had a few more warnings pop up just a few weeks later. GMC now says there is a misfiring in one of the positions. I’m terrified of driving this car with my children as I don’t know when it will shut off again and how bad it will be!

While driving about 70 mph in the express lanes, the vehicle suddenly lost power and drifted like it went into neutral. There were no warning symbols. The vehicle could not restart even while coasting. After stopping, it locked itself in park and would not shift out of park. My family and I were trapped on the express lanes for over an hour in a dangerous location. The vehicle stayed stuck in park even on the tow truck. The dealer confirmed metal in the oil filter, a blown main fuse, and knocking when starting. The recall inspection and remedy were already done, but the failure still happened. The vehicle is undriveable and the required recall repair cannot be completed because the replacement engine is on backorder with no ETA.

My wife and I were traveling to Denver CO to pick up my son and grandson from the airport. The engine started to make a very exaggerated rattle. We found a dealership near our motel where we took the vehicle to and were told not to drive home that the engine needed to be replaced. We had to arrange our own transportation for both us and the vehicle 8 hrs back to our home in Rapid City, SD where our local dealership replaced the engine. The vehicle had approximately 65,000 miles when this occurred. Fortunately we were in a populated area when this occurred as there is a lot of very sparsely populated area between our home and Denver. This malfunction not only cost me a lot of money but also put my family at risk in unfamiliar areas.
