2023 GMC Yukon XL complaints

The contact owns a 2023 GMC Yukon XL. The contact stated that immediately after purchasing the vehicle, the battery failed and was replaced on two separate occasions. Additionally, while driving or reversing, the braking system erroneously activated, causing the vehicle to abruptly stop. During the failure, there were no other vehicles or large objects nearby to cause the Forward Collision Avoidance system to activate. The vehicle was taken to the local dealer on several occasions, but no failures were found. The vehicle was not repaired. The manufacturer had not yet been contacted. The failure mileage was 50.

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

While driving on a busy highway, the engine stalled and could not be restarted. We were in the left lane and thankfully traffic was light and i was able to get to the shoulder. No warning and no check engine light before stall. After numerous attempts and about 15 minutes it did restart. A few miles later same issue and could not restart. We were 200 miles from home. Called GM and they sent a tow truck. Dealer had the car for almost a month and replaced the engine because they found metal in the oil and determined that the main bearings had spun. The concern is that the replacement engine is presumably a 2024 and the issue could happen again.

While driving on the freeway at about 70mph, the lights on the dash lit up and the message "Push Button to Start" showed up. At that point the vehicle started decreasing in speed. When the accelerator was depressed, nothing happened. Luckily the freeway was not crowded and the vehicle was able to coast the side of the road where it came to a stop. Pushing the start button did nothing except bring up the dash information. Engine would not start or even try to start. AAA was called and the car was towed to a dealership. The dealer has since determined that the engine is locked up. The oil had metal in it and an engine replacement will be needed. They have put in an order for a new engine. There were no warning lights or CELs of any kind. The engine just stopped working without any warning. The 6.2l engine on the GM line of SUVs and trucks seems to be known for doing this. If this were a busy time of day or there was more traffic it may not have been so easy to pull to the side of the road. It is only a matter of time before these engine issues result in an injury or worse, a fatality. The solution to replace a faulty engine with another engine that has not been redesigned or fixed is an unsafe and risky solution.

Multiple issues...I bought the vehicle in Oct. 2023 1. BRAND NEW.... First day I brought the vehicle home there was a whining sound coming from the transmission. The reaction carrier assembly had to be replaced along with all other components. The transmission had to be completely removed from the vehicle and repaired. 2. In May of 2024 I had to have the lifters replaced on one side of the motor. 3. Right now it's in the shop with a blown motor. Yes there's only about 43,000 miles on it and the motor is blown and has to be fully replaced.

I was going about 53 mph and went to pass another vehicle. While in the oncoming traffic lane, the transmission went out. The engine revved up and the gas pedal did not work. The vehicle has been inspected and was found to have a faulty control module that possibly caused the failure within the transmission. The parts are all on "indefinite backorder" and I have a $50,000 loan on a $60,000 vehicle that is now a paper weight.

Good afternoon. Our rental car we picked up from the Denver International Airport on [XXX] had numerous incidents of emergent braking at highway and non highway speeds which were reported to Sixt ( car rental) and documented on the dates in which they occurred, [XXX] (7-8 occurrences ) and [XXX] (3 occurrences-2 after a car wash). On the day in which the first occurrences happened, the car rental company representative from Sixt, 3way connected me with a mechanic from Annex who advised washing the vehicle to ensure the sensors were clean. I did proceed to wash the vehicle on 1.25.25. This same company, Annex Automotive, then evaluated the vehicle on 1.29.25 after emergency breaking occurrences continued of which [XXX] was the worst. On [XXX] there were no vehicles in front of or behind us nor to the sides of us and the roads were completely clear. It was also dark out. Attached you will find evaluation with validation there is a mechanical concern with the vehicle. On [XXX] the extremely unsafe occurrence of emergent braking occurred with skidding tires and the doors locking and unlocking at the same time occurred. This vehicle was completely unsafe to drive. I, as well as my passengers/family, are very lucky the road conditions were moderate on [XXX] and clear on [XXX], or these emergency Breaking issues could have caused a serious accident. There were a total of five of us in the vehicle when all of these occurred. I am from Minnesota and have a Yukon XL so I am comfortable

While driving with my cruise control set to 75, my vehicle began losing speed and power for no apparent reason. I was able to fortunately pull over on the shoulder of the road when the engine turned off without pushing the stop button. At this point I put the vehicle in park and tried to restart the vehicle with no luck. It was at this time I contacted my husband and he was able to come load the vehicle on a trailer to tow to our GMC Dealership. This happened on January 28, 2025. There was 60,407 miles on the odometer. The dealership was able to tell us that the motor seized due to a bearing failure. I am glad that I was able to get over to the shoulder of the road and was not in the middle of road construction. This was a scary situation that could have been much worse.

Vehicle went to GM for recall repairs on 02/24/25 the morning after when I cranked my car it was dead. Jumped the car off then began hearing a "clicking noise" GM advised I replace my serpentine belt as they noticed it needed replacement when doing the recall repairs. 02/26/25 serpentine belt was replaced but car still seemed to have power issues when cranking. 02/27/25 car barely cranked then while driving down the highway I lost all power and power steering to the vehicle. There was no warning, no check engine lights etc. The screen went black then car shut off then the screen said "press start to restart." I was BARELY able to get the vehicle safely off the road with vehicles in front, behind, and in the other lanes. It could have caused a fatal accident. GMC still has my vehicle with NO UPDATE on replacement engine timeline.

Recently, while driving my 2023 GMC Yukon Denali XL Ultimate (with only 19,457 miles) on the expressway, my vehicle suddenly lost all power and steering at high speed—without any warning lights, noises, or alerts. One moment everything was normal, the next I was gliding in silence, completely powerless in a 6,000 lb vehicle surrounded by fast-moving traffic. I was nearly sideswiped multiple times as I tried desperately to avoid a potentially deadly accident. This failure wasn’t just mechanical—it was terrifying. And it could have cost me my life. What happened next only made things worse. GM Roadside Assistance left me stranded on the side of the road for nearly 4 hours. Multiple tow trucks were sent, but none had the right equipment because the vehicle could not be put into neutral due to the engine failure. I was left vulnerable, frustrated, and utterly unsupported while GM fumbled through their response.

Vehicle started making noise and idling rough 1-2days after receiving it back from oil change. It was absolutely fine and out of nowhere this happens. I’m great with cars and this is my 5th GMC Yukon and I bought this one at 0 mileage so I am very familiar with this car. There is absolutely no explainable reason my car is doing this I had it inspected and the dealer told me this has been happening lately to a lot of the gmc Yukons and I would need major engine repair for a brand new car!!! Over 20k in repairs and parts. I have 6 children and we have had to abandon the vehicle on Christmas Day to drive our old 2019 GMC Yukon which I think is starting to sound a lot like the 2023 under the hood! It’s roughly idling to. I’m afraid we might be taking the bus if I don’t pay 20k. I looked to see if there were recalls but found none. there is no way engine failure should just pop up after we spent tons of money keeping these cars in perfect shape and only being serviced at the dealership. This should be investigated and repair records pulled to find people who are not aware

Vehicle "Low Oil Warning" light appeared at approximately 3000 miles after an oil change. Checked the oil and it was nearly 3 quarts low. Without any visible leaks or loss of oil, I called local GMC service department and had them inspect. They found that 4 pistons and other components needed replaced due to failure. There was no signs or symptoms other than the warning light. The car has been in the shop for 3 weeks. I currently do not have my vehicle, but I was going to use this vehicle for a long road trip and I'm sure this would have been a catastrophic loss, and possibly a safety issue for my family traveling 1k miles at highway speeds.

Driving on highway with my [XXX] daughter in the car, screen all of a sudden flashed “press start” on the dashboard and the car died in highway at the off ramp exit. Had to call state police because we were blocking ramp and almost got hit multiple times. Could not get car to restart, state police towed off highway for $200 and AAA towed to dealer. Took over a week for dealer to claim GM owned up to engine failure. No rental car provided. Sold for a $37,000 loss a year and a half after purchase with only 27,000 mile on the vehicle.

I was travelling on the interstate at 75 miles per hour and the vehicle started slowing down and completely shut down. The engine warning light then came on and I had to coast to the side of the road. I was on the side of the interstate for about 45 minutes and the vehicle had to be towed. The repair shop informed me it was a complete engine failure requiring a new motor and that GM has an extended backorder time due to this being a widespread problem for these model years with the 6.2L gas engine. The vehicle is currently at the dealership and will be there for several months waiting on an engine.

My daughter and I were coming and got off of the [XXX] on the [XXX] exit ramp to go home. When we were pulling up the vehicle suddenly showed the check engine light and the vehicle turned off. It would not go into neutral, it would not restart. I am being told there is no active recall on it; however, in researching, it appears that I am one of many cases of this exact scenario. Being stuck on a busy exit ramp is not safe and had this have happened in the road construction on [XXX] , this could have been a much different scenario even fatal. This vehicle is a 2023 with 40,355 miles on it. The Denali is currently at the dealership it was towed to, and I am waiting on the diagnostic.

My wife was travelling down a two-lane road at 50mph when the engine suddenly shut off affecting steering. She was able to maneuver to the shoulder, but the vehicle would not restart. Could have been much worse. Had it towed to the dealer we purchased it from, and they informed us the engine had seized. There were no warning signs or dash lights indicating there may be an issue.

•What component or system failed or malfunctioned, and is it available for inspection upon request? Driver and passenger side rear view mirrors will not hold memory and auto adjust while driving at times. Been to the dealership 5 times. They could not repair and just said that a software update should fix it, but it did not fix it. I will program the mirrors to the preferred settings but when I re-enter the vehicle after shutting it down, it doesn't always retain the memory, and they go to random positions. This usually happens after 5 miles of driving the vehicle. The passenger side mirror will go down so I could see the curbs while in reverse but when I go into Drive, it does not go all the way back up. I will be flying to visit family but the vehicle will be at a different dealership from 3/26/2025 to 4/1/2025. •How was your safety or the safety of others put at risk? After adjusting the mirrors, I left my garage with my kids in the car and started driving to our destination. While entering the highway, I went to check my driver’s side rear view mirror and noticed that it was pointed to a random position. In that moment, I was trying to match the highway speed to enter, there was a vehicle in front of me, a vehicle behind me, and a vehicle on the highway exit/entrance lane that I was trying to be cognizant of location to adjust speed properly. I ended up doing multiple shoulder checks which caused me to lose visibility of the vehicle in front of me multiple times. •Has the

During a cross country road trip on [XXX] we experienced the dreaded 6.2 gm engine failure. As I was driving I lost all power going up a steep grade in the fast lane of a 4 lane interstate. There was no room to pull over to the left side so I had to very quickly cross 4 lanes of traffic without any power. I was able to get the yukon off the interstate as safely as possible. Once I placed the vehicle in park it shut off completely. I tried to restart it several times. Finally got a message on the dash saying engine oil cooler was hot or oil was overheated. Called gmc and got a tow to nearest dealership. I rented a vehicle on my own dime and drove that back to north dakota where we live. We are still in the process of getting some of our expenses reimbursed. I called an Uber to pick my wife and 3 daughters up to get them to a near by hotel. My son snd I stayed with the vehicle on the side of the road till the tow truck arrived. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to express serious safety concerns regarding our 2023 GMC Yukon XL Denali, which has been in our possession for less than two years and has only 24,000 miles. On multiple occasions, while driving at high speeds on the freeway with our four young children, the vehicle unexpectedly lost power and shifted into neutral without warning. This occurred approximately four times on March 9, 2025, when we contacted OnStar for assistance. Despite their response indicating no alerts on their end, we were advised to reach out again if the issue persisted. Unfortunately, the problem did occur again on March 16th, which prompted us to contact OnStar and have the vehicle towed to the nearest dealership for further evaluation. The service department has since informed us that the motor requires replacement. Upon conducting additional research, it seems this may be a known issue with many vehicles manufactured by GM around the same time. We are deeply concerned by this safety hazard, especially given that the malfunction could have led to a life-threatening accident. While we are grateful that we were fortunate enough to avoid any serious consequences, we believe a solution beyond standard repairs is necessary to restore our confidence in the safety of this vehicle. Our family’s well-being and trust in the reliability of our vehicle are of the utmost importance.

While on the expressway driving at highway speed the engine started backfiring and many codes were displayed on dashboard including “ rear drive disabled” “ service ECU” and many others. Pulled over and Had GMC Yukon towed to dealer. I’ve seen many complaints of the same thing and found this recall on your site GENERAL MOTORS DCS6866 URGENT - DISTRIBUTE IMMEDIATELY Date: April 24, 2024 Subject: N232413430 - Customer Satisfaction Program The dealer said they would fix broken valves and I would have to pay for the new computer that’s not under warranty.

Engine stopped and vehicle went into neutral. Family of 5 in the vehicle on a busy highway. Once pulled over safely from the highway and shut off ignition, the vehicle stayed in park and would not shift to neutral, the engine would not restart. Vehicle had to be towed into the GMC dealer. No warnings, messages or symptoms prior to the failure. The vehicle was just at the dealer for routine maintenance 4 days prior. Dealership found that the engine had seized.

Engine was making rattle noises and oil low message appeared. Brought to dealer who changed oil and said they couldn’t detect noises. I asked for a road test and while driving the tech noticed it, then the car died and shifted into neutral without warning.

While in use on several different occasions, the front windshield wipers malfunction. They stop working for hours sometimes even days. This is a hazard especially if you are in the middle of driving and it’s storming. The a few days ago for instance I was driving and all of a sudden they stopped working while I was driving home in the rain, at night. I had to immediately pull onside the road and wait for the rain to stop because I tried everything to get them to start back working. Including observing and trying to make sure it wasn’t the wiper /signal switch. I even went under the hood and checked to see if the fuse had blown or if there was some kind of wiring undone. Still nothing. I have taken it to the dealership and several people complain about the same thing but no remedy has been presented. They just all of a sudden start back to working out of the blue. This is definitely a safety hazard and these wipers or wiper motor should be recalled and fixed immediately in my opinion. Please help. Save some lives before it’s too late. Thanks for helping with this matter.

Engine failed during trip on interstate without warning after 23k miles. Car went into neutral and we were without power. We coasted to side of road and had to be towed. Dealership has ordered new engine which will be covered under warranty. There were no warning lights before, during or after the incident — no check engine light. The only indicator is that car started making a rattling noise from the engine a few seconds before we lost power.

Vehicle is on its second engine. Shut down unexpectedly in middle of the road, with my three young children inside.

Upon acceleration the engine began to sputter with a clanking noise. After turning around to pull back into my drive way the engine began to work properly. I had the vehicle towed to Master GMC Augusta,GA. After the car was at the dealership for several days, I was told the issues could not be duplicated and there were no error codes. While returning home from the dealership the car began to sputter and decelerate at this time multiple lights flashed on and off on the dash including the check engine light. As I pulled to the side of the interstate the car once again corrected itself and all lights went out. I reached out to the dealership again. The car was returned to Master GMC again. This time I was notified the engine had failed due to metal shards in the engine. Since this vehicle had only 4988 miles at the time, and I had a 2021 Suburban prior with lifter failures, I was hesitate to keep this vehicle. I did trade the 2023 Yukon XL Denali at the time of engine failure.

Driving at highway speeds at night when engine sputtered, vehicle shifted itself into neutral and shut engine down. Slight difficulty steering for 1/4 of a mile with traffic continuing to pass at full highway speeds but was able to coast to a side road. No warnings of failure or check engine lights prior to event. Had just stopped for gas continued on trip and cruising about 77mph and hear a few noises as if vehicle ran our of gas and dash lit up letting me know it was shutting down, then shifted to neutral. Now dealing with GM travel interruption team and being told that it is engine failure due to faulty lifter/rod/bearing issue with no timeline as to when an engine replacement will be available. It has been inspected and confirmed by GMC service department in San Angelo TX

1. My engine failed at 10,000 miles, seized up completely. 2. Safety was a HUGE risk factor as the engine went out while driving 65 mph in a dangerous canyon highway, which made me lose control of being able to drive the vehicle to safety as I was needing to coast to the top of a hill and then coast down to even find a safe spot to pullover. My safety was also at risk because it then left me stranded in a canyon with no cell service where I was (and I couldn't even connect via OnStar because of the area I was stuck in), leaving me stranded for over 3 hours in 100 degree weather with no place to hide from the heat in the middle of summer. I also had my [XXX] with me and thank God we made it out of that situation alive. And thank goodness for bystanders I don't know what I would've done without them. 3. Yes, an engine replacement was made via warranty, but the new engine still make clunky/grindy sounds and even after having that looked at, I was turned away because apparently there were no performance issues but I still feel like I cannot rely on the vehicle especially driving longer distances. 4. Yes. see comment for #3. 5. NO warnings AT ALL were ever on my dash regarding my engine going out. There was never a check engine light prior to the engine seizing, nothing. So how was I supposed to know my engine was going to give out on me at only 10,000 miles? Regular maintenance was kept up to date. It just went out randomly with no warning.

While driving down a two-lane highway, the vehicle unexpectedly lost power and shifted into neutral. We coasted to a stop and pulled into a driveway, at which point the vehicle would not restart. The vehicle was towed to the local GM dealership, where we were informed that the engine required replacement.

I was driving down the highway at 75 miles per hour and my engine shifted from drive to Neutral on its own, luckily I was able to get off to the side of the road as it would not shift back into drive. I got off the highway and was able to put it in park but it would not shift into any other gear. I turned the vehicle off and it would not power back on. It was completely dead. I had to have it towed and drug up onto truck and back off the truck as it was not shift into Neutral. It has now been at the GM dealership for 16 days. The engine had seized they said and needs a new one. this is a 2023 and only has slightly over 20K miles on it. They have told me there is a national shortage on engines and I am in line to get one but there is no telling on how long that will be. I am out of a car for 2 weeks and who knows how much longer. GM has given me a rental car but a very small SUV that does not fit my family. I have no idea how long it will be nor do they until I get a new engine in my vehicle. I was fortunate I was able to get to the side of the highway and stop safely.

Motor locked up while driving on highway to vacation, when i tried to get warranty at a nearby dealership i was told engine was on back order with no release and the only option i had was to purchase a new vehicle . vehicle was under a year old with very low mileage on it.

While driving, vehicle threw an error “ reduced acceleration, drive with care”. I had my children in the car when the car abruptly reduced speed and car jerked. It was very scary while driving. It was stuck in 5th gear. I was taken to dealership. Code showed it needs a Transmission Valve Body replacement. Part # 24065353. Dealership has stated part is “on backorder with no ETA of the part”. My car has been sitting on the lot for 17 days waiting to be fixed.

2023 Yukon XL AT4 with 6.2L engine. [XXX] started to hear rattling noise coming from the engine area. I took the vehicle to a GMC dealer in Houston TX. The dealer diagnosed the problem as a defective transmission plate? Said they would have to order the part. Part arrived and while at the dealer they decided to inspect the oil pan. In the oil pan they found metal shavings. It was reported to me yesterday [XXX] that the engine would need to be replaced. This vehicle has roughly 17,000 miles and it’s been just over 1 1/2 years since purchased brand new by me. No confirmation of when a new motor will be available for replacement. Was told it could be months. Was also told that the vehicle is unsafe to drive since the engine could lock up at any time based on their findings.

While driving on the interstate at 75mph the vehicle shutdown and would not allow a restart. I had to coast over to the emergency lane with no engine power. Once stopped the vehicle would not start. After having the vehicle hauled to the dealership I was informed that the engine had locked-up and a new engine would have to be ordered and replace the engine. The dealership could not provide me with a repair date because they said GMC has lots of problems with this engine and it would be backordered.

Engine blew up on interstate and left the vehicle in mobilized with only 60,000 miles and all regular maintenance was completed just catastrophically shut off and would not start in the middle of the interstate

Our 2023 GMC Yukon XL Denali that has suffered multiple severe mechanical failures well beyond what is reasonable for a vehicle of this class. G At approximately 14,000 miles, the vehicle’s 6.2L engine catastrophically failed, rendering it inoperable and requiring a full engine replacement. The engine seized and failed while operating the vehicle with her 3 small children on board and nearly caused a catastrophic accident. As a result, the vehicle was out of service for eight weeks, an unreasonable disruption and an unacceptable failure for a luxury SUV of this caliber. Now, (02/11/2025) at just 20,400 miles, the vehicle’s injectors have failed, further reinforcing that this vehicle is defective, unreliable, and unfit for continued ownership. This vehicle was purchased with the expectation of owning a dependable, high-performance SUV—not one plagued with major mechanical failures at such low mileage. The repeated, severe defects have substantially impaired the vehicle’s use, value, and safety, leaving use without reliable transportation for extended periods. Given these circumstances, it is clear that this vehicle does not meet the quality and durability standards expected from General Motors’ flagship SUV lineup and present SERIOUS risks of catastrophic injuries and/or death.

We were driving uphill on the highway, about 60 mph when the engine appeared to loose some power for about 10 seconds even though the engine was reving higher, and the ln the engine cut out. We coasted to a stop and then the electrical system was cutting out. I tried to restart the engine but it would not turn over at all, and the car’s electrical was intermittent. There was no warning or error lights before or during the engine failure. Photos provided are the messages on the instrument cluster when attempting to restart the engine. Vehicle was towed to the local GMC dealership, and they are replacing the engine under warranty. No eta on the engine replacement at this time.

At around 23,000 miles the vehicle collapsed a lifter - Took it to a dealership, fixed the lifter and asked them to confirm that the lobes of the cam were good and that all bearings were in good shape - approximately 2 weeks later, complete engine failure on a busy highway, no good place to pull off the road, no reimbursement for towing bill, no rental car - dealership put new motor in (took 5 weeks and GM did nothing to help us with the situation) and now we have the same bad 6.2 liter motor in the vehicle that is likely to fail again withing the 25,000 miles. Manufacturer refused to answer specific questions about the motor and could not tell me if this new motor was built to satisfy this known issue - the new motor has the same part number as the previous motor so consensus is that it has the same failure possibility leaving family in a dangerous place on the roads. GM still refuses to discuss this with us as the customer!

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 had not experienced a failure with the car seats.

At 9,900 miles my safety camera system failed which disabled the cruise control and all safety features that used the camera. Car was out of service for nearly two weeks and subsequently fixed by the dealer under warranty at no charge. At 11,300 miles I was driving on an interstate highway in the left lane at rush hour, without warning the car stopped accelerating the car shifted into neutral and totally lost power. It was a very dangerous situation with me in the left lane in heavy traffic. I am a skillful driver and thankfully I was able to make it off the travel lanes on the highway. The temperature was 18 degrees at the time and I had to wait outside for a tow truck. The engine seized without warning or noise and this presents a severe danger to the driver of the vehicle and other vehicles on the highway. There was a substantial possibility that other vehicles could not avoid me as I was exiting the travel lanes. There was also a substantial possibility that the vehicle would simply be in the travel lane stopped on a divided highway.

The 2023 GMC Yukon had a complete loss of power and engine while driving 65 mph on a highway. The vehicle was unable to restart or be placed into neutral. No previous issues and no indications of failures. No fault codes or lights indicating any issues. Dealership informed me that the engine stopped working and gave an estimate of greater than 4 months for any replacement or repair.

Wife was driving down the interstate (18,000 or so miles on vehicle), and engine suddenly shut down causing loss of power. Had to safely maneuver vehicle off the side of the road to try to restart. After restart, continued driving without issue until noticeable clicking noise and engine thumping noise. Vehicle was diagnosed with lifter issues. After repair, and 2000 miles additional driving (20,000) ticking and thumping noise returned. Taken back for service and notified full engine replacement is necessary.

The engine failure was confirmed by dealer. My wife and I were traveling on I-74 at approximately 72 mph when the truck began to jerk slightly. This continued for about a mile, prompting me to ask if she felt it too. Suddenly, the truck lost power while we were driving on a two-lane interstate, putting our safety at risk. Fortunately, we were close enough to an exit and managed to coast to a nearby restaurant. Thankfully, it was not during peak business hours, and no vehicles were directly behind us at the time. Given the heavy semi-truck traffic on this stretch of interstate, the situation could have been significantly more dangerous.

The engine failed at highway speeds on approx. July 15 2024. Filed a claim with GM. GM replaced minimal engine parts to get the car running. GM refused to acknowledge this was a safety issue. Engine failed at highway speeds again approx 09/20/2024 this time just shutting off. When the engine oil was drained at the dealer it was silver. The entire engine was replaced this time. Again GM refused to acknowledge this was a safety hazard. After engine replacement the low oil light came on at the time of an oil change. I am monitoring oil burn on this new engine.

The engine completely failed without warning. The vehicle stalled and would not restart. I was unable to put the Yukon in neutral in order to move it out of the way of traffic. As I was in the process of turning I was completely blocking oncoming traffic. When the vehicle was finally towed to the dealership they told me that there was no oil in the engine. I had checked the oil 2 days prior and the dipstick showed full. We had no leaks in the driveway and no low oil indicator came on to warn us. A dealership in Holland Michigan had just looked at the vehicle to take care of some recall updates and reset the oil indicator telling me that we could get it taken care of later as it was only 2000 miles since the previous oil change and the previous oil change company hadn’t reset the percentage indicator properly. In the case of LOW OIL there was no warning whatsoever.

Engine failure - Yes, vehicle at dealer Engine failed on a busy road during rush hour, family in vehicle. Dealer confirmed engine needs replacement, lead time unknown. Expected later than Oct 2025. Inspected by certified dealer service dept. Warning lamps prior to failure, roughly .5 miles prior. Limited power.

I have had this vehicle serviced twice for the electrical issue on the running boards. While driving and while parked the running boards constantly deploy and store on their own or get stuck at a half way position. This will happen even if I have them turned off or on.

While traveling on vacation, my family and I experienced a catastrophic engine failure in our GMC Yukon Denali, leaving us stranded in a small Texas town. After having the vehicle towed to the nearest dealership, we were informed that the engine is seized and requires a full replacement. Unfortunately, the dealer has no estimated timeline for when GM will be able to provide the necessary replacement engine, leaving us in a difficult and uncertain situation. This has caused significant disruption and hardship for my family.

Engine had to be replaced at 25000 miles.

My vehicle stopped on the middle of highway when the engine seized. I had to call tow truck and tow it to a dealer. It’s been 2 months without my vehicle, the dealer has engine on a back order and offer no remedy
