2023 GMC YUKON XL Engine Problems

Engine issue crankshaft problem

my engine was part of L87 engine GMC Yukon Xl 2023 recall, they checked the car at 41,000Miles in aug-sept 2025, then they suggested different oil to be used, they changed the oil and thats it, 5000 miles later my engine died on the high way, it shut off and car seized and shut off on the highway and did not move. I towed it to the GMC dealership, they confirmed the engine is seized, but they have been very secretive, they did not tell me whats wrong, they been some what ignoring me, I dont have a car its been few days, no one reached out to tell me whats happening, no offer to give me a loaner, when I kept bugging me they said we're opening the enigne to send the broken part inside to the GMC headquarters, I asked to know what's the issue what's happening but...

I was on the interstate and when I was passing a vehicle in the middle lane the engine lost power, shifted to N. I tried going back to drive it would not shift. Stopped the suv and tried restarting it. When I pushed on the brake and tried to start it the whole vehicle would loose power to all my screens. I had this vehicle towed in back in September 2025 due to not cranking over when starting. They did the recall for the engine at that time. The engine light would randomly turn on but would go back off within the same day.

2023 Yukon Denali XL 6.2l: GM oil change recall performed (October 2025) and GMC dealership noted no issues. Prior to recall oil change, at aprox 5k miles interval (45K total miles), check engine oil light on dash and was over 1 quart low. Next oil change at aprox 50K miles, no check engine light came on, but certified mechanic drained and measure oil level, 1.5 quarts low. Engine often sounds odd at cold start, ticking sound. Now an oil change is $100 more, due to special oil, but not compensated for extra cost. Brake calibers failed. February 2026, engine light on, then off, then hood latch dash light warning now on and off. Huge safety concerns with the 2023 GMC Yukon 6.2L.

POST-RECALL 25V274 ( & EA25007, EA25001) EXHAUST INTRUSION WITH CARBON MONOXIDE POISONING HAZARD Following the complete engine replacement under GM recall N252494000, my vehicle has developed a severe and persistent exhaust intrusion that allows toxic exhaust fumes, including carbon monoxide (CO), to enter the passenger cabin. CO levels have measured a peak of 83 PPM and consistent reading between 20-37 over multiple tests. PATTERN OF POST-RECALL EXHAUST SYSTEM FAILURES Vehicle has been in for service 6 times, over 100 days, as part of the engine replacement plus (metal found in the oil pan). Since recall, the vehicle has had an exhaust smell and noise rattle issue with the following exhaust system components deemed failed and been replaced: 1. Radiator cap (leaking onto exhaust) 2. Exhaust muffler (replaced TWICE - June 2025 and August 2025) 3. Exhaust clamps (leaking) 4. Left exhaust manifold (warped) Critical Finding: Despite replacement of virtually the...

On 12/22/2025 I took my 2023 GMC Yukon in for the L87 recall. After receiving information that my vehicle passed the recall they told me that the oil would be change to from OW-20 to OW-40 and that my oil changes would go up in price (double the price) due to the oil being a high performance oil. On 01/05/26 exactly two weeks and 616 miles later our engine and lights completely stopped working while driving it on the road!!! The vehicle would not start or switch into neutral so we could get the vehicle off the road due to blocking traffic! The vehicle was towed the GMC dealership and had to have a new engine replacement. We were out of our vehicle for 31 days. Now our vehicle rear view camera guidelines have stopped working and now have to put that under warranty claim.

On two separate occasions, while driving at approximately 60 mph on New York parkways, my vehicle unexpectedly shifted into neutral and lost power without warning. During the first incident, a message appeared instructing me to “press start to continue.” I was able to restart the vehicle and drive home. Two days later, the same failure occurred again under similar conditions. This time, after pulling over and pressing the start button, the vehicle shut off completely and became totally inoperable. The vehicle had no power and would not restart. At the time of this second incident: - I had my [XXX] child in the vehicle - The outside temperature was approximately 20 degrees - Recent snow made it difficult to pull fully off the parkway - Police assistance was required to ensure our safety - We waited nearly two hours for a tow truck due to the hazardous roadside conditions This...

I am reporting a catastrophic engine failure involving my 2023 GMC Yukon XL Denali, which was subject to a GM-issued recall related to engine failure. On January 10, 2026, at approximately 1:00 a.m., while traveling at highway speed (approximately 65+ mph) on a multi-lane highway, the engine suddenly failed without warning, resulting in a complete loss of power. I was forced to make immediate evasive maneuvers to reach the shoulder while avoiding semi-trucks and other vehicles. The sudden loss of power created an extremely dangerous situation for myself, my passengers, and surrounding traffic. After the engine failure, the vehicle could not be placed into neutral, preventing it from being moved out of traffic if it had stopped in an active lane. This design issue significantly increased the risk of a collision. I was stranded on the roadside for several hours in cold conditions awaiting a tow. The failure was later...

Following a catastrophic engine failure in my 2023 GMC Yukon XL Denali, I discovered that the vehicle could not be shifted into neutral once the engine failed. This prevented the vehicle from being moved out of traffic if it had stopped in an active lane. The inability to place the vehicle into neutral after a loss-of-power event creates a serious safety hazard, particularly on high-speed roadways. In the event of a failure occurring in traffic, occupants may be left stranded in a travel lane with no ability to push or reposition the vehicle, significantly increasing the risk of a rear-end or multi-vehicle collision. This condition occurred immediately following the engine failure and was not accompanied by any prior warning or instructions to allow safe vehicle repositioning. I am unaware of any manual or mechanical override that would allow the vehicle to be shifted into neutral under these conditions. This design...

Vehicle was taken to dealership and test was run. Service manager notified me it passed and told us about change of oil. Then recently engine stopped on us twice on the interstate with no power. We finally got it to the dealer and while they were test driving it lost power and they had to have it towed. Now we have been told we are needing a new engine and have not been given any time line. We have also read that many time the solution even on the new engine is not fixing all issues. We just want a safe vehicle returned to us.

On January 19, 2026, Recall 25V274 was performed on my vehicle, and this was not disclosed to me when I picked up the vehicle from the dealership, Courtesy Buick GMC in Louisville, KY. I only found out when I got home and read through all the service notes. I contacted the dealer on January 19 after I got home, asking for explanation and have not heard back. The Recall Remedy failed. Since the service, symptoms of hesitation, lack of propulsion and low MPG persisted. As of Feb 1, the vehicle has suffered a transmission failure and is unsafe. The dealer told me verbally everything was fine, and in the service notes from Jan 19, they noted vehicle as 'Operating as Designed and Within Spec' despite performing safety recall work."

We had the L87 engine recall completed at 14,318 miles on Nov 20, 2025 on our 2023 Yukon XL Denali with the 6.2L engine. Engine passed all tests by dealer and we were sent on our way with 0W-40 and a new oil cap. Fast forward to Jan 21, 2026.... My wife pulled the vehicle out of driveway and noticed a deep pitched, knocking sound. She slowly started to drive down the street a bit and then the vehicle shut off and displayed a warning message on the dash (this was on a cold engine, not due to the absurd auto start/stop feature). She was able to restart and get vehicle back to the garage. We had just rolled 15,000 miles on the odometer the day before. Immediately called our dealer and had an appointment set for the next day. We were able to drive vehicle to dealer with knocking...

The vehicle was running perfectly fine. We pulled into a service station to fill up the gas tank, and suddenly it wouldn’t start at all. We had no choice but to have it towed to McKenzie GMC in Milton, Florida. After several days of waiting, we were told we now “need another engine.” Yes—another engine. This is completely unacceptable. This same vehicle already had its engine replaced in 2025 under recall 25V274000. It passed the PICO test, and the oil was changed to the updated 0W‑40 viscosity exactly as required. There is absolutely no reason a vehicle with a recently replaced, recall‑compliant engine should be failing like this. Something is seriously wrong with this vehicle, and it needs to be addressed immediately. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There have been several issues for which I had to take my vehicle to the dealer. I did the engine oil recall. Then 4 months later my engine was destroyed. I’ve had several issues with oil leaks. I had an issue with my running boards a few times. And I’ve had an ongoing issue that the dealer hasn’t been able to fix - a water leak (I believe stemming from the moonroof), water gets into my vehicle, on my floorboard, and behind the dash. I’ve called to record these incidents with the dealer and taken it in several times, but they are never able to duplicate it, but they have witnessed the water leakage after the incidents (which happens during heavy downpours, and isn’t all the time because my vehicle is in the garage when I’m not at work).

My family and I received a recall notice from GM. We took the vehicle in promptly and had it "repaired" by an authorized dealer. They replaced the oil cap and placed a sticker in our owner's manual. This Christmas, instead of going to Angel Fire, New Mexico, like we do every year to visit family, we stayed home in the Rio Grande Valley. On December 28, 2025, my family decided to go holiday shopping. With kids home from college, and others off from school, I packed my wife and kids (there are six of us) into our 2023 Yukon XL to go shopping. I was driving down a busy 3 lane road with a 55 mph speed limit. By the Grace of God, I had just turned from the center lane to the right (outer) lane when our Yukon lost ALL POWER and the display read something like "Press Start/Ignition."...

Good afternoon, My 2023 GMC Yukon XL AT4 with the 6.2L L87 engine (approx. 61,000 miles) suffered a sudden and complete engine failure at highway speed while I was driving between Canton, OH, and Columbus, OH, on the expressway, returning to my home in Cincinnati. There was no warning before the engine lost all power and propulsion. I was traveling in the left lane of the interstate in moderately heavy traffic. When the engine shut down, I only had steering and braking available to me. In addition to losing all propulsion, I also lost all electronics, and there was no shoulder. The complete dashboard shut down. The only reason there was not a collision was that the traffic around me could see what was happening and slowed down themselves. I coasted on through the onramp and found a shoulder where I had three lanes of traffic on my left and...

The engine experienced a catastrophic mechanical failure after the vehicle had been inspected by the manufacturer and certified as compliant with an engine recall. The failure occurred after the recall remedy/inspection was completed. The engine lost functionality while the vehicle was in use, resulting in loss of propulsion and the vehicle becoming disabled, requiring towing. The engine is currently available for inspection and is awaiting major powertrain repair at an authorized dealership. The sudden engine failure created a safety risk due to unexpected loss of power while driving. No collision occurred. The issue has been confirmed by an authorized dealership. The vehicle had previously been inspected by the manufacturer as part of the recall process prior to the failure. Prior to the failure, there were no known warning lamps or messages indicating an imminent catastrophic failure. The failure occurred after the vehicle had passed the recall inspection. This appears to...

Engine oil level drops significantly well before the oil change interval. Vehicle consumes excessive oil without warning lights or leaks. Risk of engine damage or failure if oil level is not closely monitored. Condition discovered during normal use.

Vehicle has 56000 miles currently and at 47000 transmission had to be replaced due to defective valve body. At 56000 miles, motor was replaced due to broken lifter. The vehicle currently will not start.

2023 Gmc Yukon XL SLT 5.3 Liter V8 engine As i was crusing on hiway my engine gave up lost of power knocking noise and check engine light appeared on dash it was a very serious matter when you are on hiway and engine fails on you ive gotte the car diagnosed it had known issue like the rest of GM trucks and suv Lifter failure/camshaft/push rods complete engine had to be either replace or professional rebuilt. This vehicle brand new is almost $100k vehicle which shouldnt have had this issue under 2 years of ownership and paying out of my own pocket. I urge NHTSA to take this matter in to consideration and have the GM 5.3 liter V8 engine under recall just like they have with the 6.2 liter V8 engine they have the same problem with the lifters, camshaft,pushrod failure. Thank you

Engine failure at 38k miles No service lights on dash. GM says 4 months to get replacement motor with very little help on getting rental car

While traveling on the interstate my vehicle shuttered and lost power we went to a friend’s neighborhood and the vehicle stalled when we pulled in no lights had come on until then and a knock had started. With no where to pull over I finally got the vehicle started and drove it straight to our friends house and left in on the side of the street. I had to take there vehicle home and called ONSTAR to tow it to the dealership. I have to pay for the over mileage because I was out of town when it happened.

The vehicle has experienced numerous losses of power, it has nearly stalled during normal operation, there is a horrible knocking noise coming from the engine. I have had the vehicle into the dealership who state they are unable to recreate the issue, and since the vehicle has been turned off the recorder shows noting either. They have performed an inspection and changed the oil, but the vehicle still has the issue. It knocks and shudders like it's cold, it comes very close to stalling and then seems to recover, this has happend twice while making left hand turns, it has completly lost power even while depressing the gas, but again they indicate they can't recreate it, so there is nothing they can do. I am scared for my safety, and that of the child I drive daily. There have been several instances in the last few months.

The vehicle underwent a recall inspection on September 8, but on October 2, the vehicle still experienced a serious engine failure. The vehicle was undrivable, and the dealer inspected it and opened a TCA case. However, General Motors stated that it had passed the recall test and was not covered under special warranty, and asked me to pay $5,000 for vehicle repairs. I believe this is an engine malfunction related to the recall, and the manufacturer should replace the engine for me free of charge and refund my 5,000 .

On May 23, 2025, I purchased a 2023 GMC Yukon XL VIN: [XXX] from the GMC dealership.
 At the time of sale, I specifically asked about the active GM engine recall. They assured me the vehicle had been inspected and was unaffected. On October 30, 2025, the engine catastrophically failed on a highway while my family — including my two small children — were in the vehicle. This created a dangerous emergency situation as I had to avoid high-speed traffic. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving and pulling up into my driveway when suddenly the message “push start button to start engine” comes on with an alert sound - I notice my gear is lighting up “N” and when I pushed the start button it sounded like my engine restarted. I remained in neutral and had to change it back to drive myself. The engine randomly cut off

I have had two incidents. The vehicle is hesitant. It’s spudders, it stalls. You can hear it in the engine at idle and especially at cold start.

My vehicle’s engine failed for the second time while driving on the road. The first time a few months ago while my wife was driving. The engine failed and brakes failed. Fortunately she was on a back road a coasted to a stop. Car was towed to dealership. They said there was no problem. Received recall letter about a month ago outlining this issue. Yesterday, [XXX], I was driving with my daughter and the car stopped again while driving. I was in traffic and narrowly missed an accident. Gwinnett county police came to the scene and towed the vehicle to the dealership. I am not sure if the female officer made a report. But she requested the tow truck because I was blocking traffic. We often drive on the highway for work commutes. This could have happened and anyone in my family could have been fatally injured. I would like...

GM issued a recall, N25249000 after hundreds if not thousands of complaints of catastrophic engine failure. My engine was impacted. It failed Sunday, [XXX]. I limped it to Mike Marroone dealership in Longmont, CO, on August 5th. That afternoon they confirmed my engine and various other components needed to be replaced. At this time GM was flooded with recalls and the whereabouts of all necessary parts were unknown and could not be tracked. It was so bad that the dealer could give no timeline as they had 5 vehicles waiting for engines. They also were replacing engines, and the replacement engine would fail immediately. Without notice, an engine and parts arrived after 3 painful weeks of sitting in the unknown. The vehicle was returned to me on August 23nd, 2024, 19 days after I dropped it off. During this time I was paying $977.50 for a car payment plus $130...

the coolant control valve failed, and now its been in the dealership for over a month. I have been reading online that this is not an isolated issue, and many people experience months of wait time getting the part because its apparently nationally backordered because of this problem.

All of a sudden while driving on [XXX] in PA, the vehicle made a loud click noise, started squealing and randomly slowing down as if we were slamming on the brakes, but it was all engine related. Then it was shaking vigorously while we were parked. We got towed to a local shop in the middle of nowhere, and they just called stating it could be a valve spring that broke and they’d have to take the valve cover off to determine it.

Speed control became stuck and I had to hit my breaks to stop acceleration. Vehicle stopped shifting while driving down the road periodically. Warning collision lights and traction control lights randomly come on with nothing in front of vehicle. Yesterday vehicle would not start or even unlock. When I did get the vehicle to start by manually unlocking it and trying over and over it would not go forward or backward although the engine did rev up. All warning lights were on including traction control and check engine. It did randomly start moving but the “service steering column” light and check engine light are still on . The car periodically revs up while going down a hill when it needs to downshift instead. It has completely shut off driving down the road through town and stopped. I had to hurry and turn it back on as there were cars behind...

The contact called on behalf of her daughter who owns a 2023 GMC Yukon XL. The contact received notification of NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact stated that while her daughter was driving on a back road at 55 MPH, the vehicle lost automotive power. There were no warning lights illuminated. The contact’s daughter pulled over and attempted to restart the vehicle; however, the vehicle failed to restart. The contact stated that a bystander pulled over and assisted with towing the vehicle to a local dealer to be diagnosed. The contact was informed that failure might be related to the recall; however, parts to...

I was at a stop on my street needing to cross a busy one. I stepped on gas to quickly move forward and it stalled. Almost causing a wreck. I have taken it in to gm it had a recall and they said it was fixed and now there is another recall and it has been at least three months now that our dealer can not resolve this issue because they do not have parts to fix the issue. The vehicle seems to struggle moving forward and when its switching gears. It is still running but I feel like something is off. I have two small children with me and we are in this car all the time. I do not feel safe driving it anymore. What can I do about this?

Vehicle surged, lost all power while driving, switched to neutral and would not restart.

Vehicle was traveling on interstate and lost power/propulsion and automatically shifted to neutral. Grave danger for eminent death/injury as a result of possible accident.

I am reporting a serious engine failure in my 2023 GMC Yukon XL (5.3L Ecotec3 V8) at approximately 68,775 miles. The engine began to run rough with a loud chatter noise, and both the check engine light and traction control light activated. Diagnostic tests at the dealer (F.C. Kerbeck GMC) confirmed a P0300 random misfire code and revealed that the lifter on cylinder #5 had collapsed, causing damage to the camshaft lobe. The repair required removing the cylinder head and replacing the lifter, camshaft, pushrods, valves, and associated gaskets and seals. Although I was told this was covered as a ‘goodwill repair’ by GM, I was still charged $3,450 for miscellaneous charges. I find this highly concerning and question whether these charges are consistent with GM’s stated goodwill or warranty policies. In my opinion, a known lifter design flaw requiring such an extensive repair should not result in out-of-pocket costs...

I own a 2023 GMC Yukon Denali XL (VIN: [XXX] ) currently under active recall for the L87 6.2L engine. GM has no remedy available and has acknowledged a risk of complete engine failure and loss of propulsion, which could occur without warning. This is the primary vehicle I have for transporting my family of seven, including a toddler. I am significantly upside down on the loan, and the dealership cannot guarantee it is safe to drive. I am requesting that NHTSA escalate the urgency and hold the manufacturer accountable for timely resolution or replacement.” INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Major recall on Yukon with no remedy listed - unable to sell vehicle or trade in with open recall.

We were traveling eastbound on I 70 around 75mph. We received no prior indication that there was a problem. The display read engine oil hot, transmission shifted to neutral, and the entire vehicle shut down. We lost propulsion and were left coasting on a major highway with no power.

I’ve inserted the question and their answer: What component or system failed or malfunctioned, and is it available for inspection upon request? Lifter valve number six failed causing it to shatter and send pieces of it throughout the engine along with other debris into the cylinders. How was your safety or the safety of others put at risk? Vehicle had loud engine knock, pulsation of power, had to pull off on main highways due to loss of power over 400 miles away from home. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, engine was serviced by GM dealership in Baldwinsville, NY for over $8,500. Will attach copy of bill. Now is doing same thing, again. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? GM as stated above. Were there any warning lamps, messages or other symptoms...

I was driving on a highway with my [XXX] son and 2 dogs when without any warning the vehicle just stopped and completely went dead. I was unable to turn on the hazards so I called 911, the police came within minutes and surrounded the vehicle to keep us from being crashed into. The brakes failed to work, the hazard lights would not work, the doors would not open other than the driver door. The police had to help remove my child and 2 dogs from the vehicle through the driver door. The vehicle could not be put into neutral so the police had to tow the vehicle from the middle of the highway. The result could have been deadly. The vehicle was completely dead with absolutely no function. After the police towed it to the police tow facility it was then towed to the GMC dealership I purchased the...

While driving at approximately 30 mph in moderate traffic on the interstate during a return leg of a 370-mile trip, my vehicle unexpectedly shifted into neutral and became unresponsive. The dashboard displayed the warning message: "condition not correct for shift," and despite repeated attempts to restart the engine, the vehicle would not engage. Although the electrical system remained active, I had no propulsion. Critically, the vehicle became immobilized in a **very dangerous curve on the interstate**, presenting an extreme safety risk to myself and others. The car could not be manually shifted into neutral for towing, prompting Illinois Department of Transportation (IDOT) to declare the location unsafe. I was stranded there for over three hours, after dark, in a vulnerable and exposed position. During the forced tow process, two rear tires were destroyed and the two front tires sustained major damage. In the days leading up to this incident, the...

I am formally requesting a complete refund for my vehicle. It has only 6,300 miles, and the remedy provided for the recall does not adequately address the issue. The recall explicitly indicates defects in the engine components (rods/cam shafts) that may lead to a loss of propulsion. Merely inspecting the vehicle and adding thicker oil does not resolve the underlying problem; it only postpones the inevitable expiration of my warranty. Currently, there are no warning lights illuminated, as the vehicle is not driven frequently. The recall raises significant concerns, and GM should be taking more substantial measures than simply applying thicker oil as a solution. This approach feels like a temporary fix rather than a genuine resolution. I have communicated with the dealership, and have been informed there is currently no solution available for this matter. They are awaiting further instructions on how to proceed. I request a more thorough...

My vehicle stalled while driving on a busy highway & I had no option but to pull over, which left me & my family in a very dangerous position. Had to remove my daughter's wheelchair onto a tow truck as the vehicle had no power to use the hoist for her powerchair. Again, on the side of a busy road! Towed the vehicle to a GM dealership, who stated there was catastrophic engine failure & the engine had to be replaced. Had no way to transport my daughter until I got a new engine since her hoist was stuck at the dealership. This was our original vehicle, until the sold me another one with the same defect (2024 Yukon for MORE money!). That vehicle was reported in Complaint 11657786.

The contact owns a 2023 GMC Yukon. The contact stated that upon taking the vehicle into the dealer for regular service, the dealer found that the engine oil level was extremely low, resulting in damages to the engine. The check engine warning light was illuminated. The contact was informed that the piston O-rings needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 22,000.

Crankshaft bearing failed, leading to engine failure at 65MPH on highway. No warning.

While driving without any warning the screen said press start. The vehicle shifted to neutral and lost all power while driving down a very busy road on the top of a hill going 55 mph. Once stopped we tried to turn the vehicle back on, vehicle would power on but wouldn’t start just click and screens flash
