ENGINE
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 driving the vehicle shut down and never would restart. It was taken to a GMC dealer and currently on a waitlist for a new engine. The wait period I was given is approximately 4 months as I was told the engine is on back order.

ELECTRICAL SYSTEM, ENGINE
While driving on the highway the engine just shut off with no warning or other indication of problem. The dashboard computer instructed to restart the vehicle, which it would not restart. Managed to get to the side of the road. But the vehicle was unresponsive. After about an hour the lights in the rear of the vehicle flickered, so I attempted to re-start -which it did, and was able to drive the vehicle to the dealer (about 20 miles away). Where the car remains today. The incident occurred Feb 2. Took the dealer until 2/6 to advise me that the engine would need to be replaced. At that time they indicated they would need to car for about 2 weeks. I contacted them on 3/3 and they informed me they had no idea when they might be able to get the parts to replace the engine - there was a 3,000 engine backlog? Clearly there is a major issues with these engines; how are they allowed to continue to sell these vehicles, and allow current owners to operate them without a notice? While I was fortunately able to get to the side of the road - have in the car lose power suddenly lose power is clearly a safety issue!

ENGINE
I was 450 miles away from home. Travelling at 80 mph in the left lane of Interstate 35 when the Yukon stopped accelerating and started coasting. I looked at the gauge clusters on the dash and it said Press Start to Shift. I looked at the shifter and it had automatically moved from Drive to Neutral. It would not move back to Drive. I then pressed the Start button like it said on the dash and the whole vehicle shutoff while still at highway speed going 70mph and still coasting. I put hazards on and moved to the right sliding in-between two 18 wheelers who gave me space thankfully then I was able to get it to the shoulder. Once stopped I moved it into Park and pressed the Start button and the dash said "unsafe conditions unable to shift", or something like that. After 2 minutes of pressing the Start button, I was able to get it started again and we started back on the road. After 2 miles, I was once again back to 80 mph in the left lane when it happened again. This time I was barely able to move off the road. We were on a long turn to the left and several 18 wheelers were all around. Once stopped, it never started again. The engine shutting off at highway speed with 18 wheelers all around put myself and 2 family members at serious risk for injury and we were just leaving a family funeral. And the 2nd time it happened, I was not able to fully pull over either causing 18 wheelers to come very close to hitting us as we were stuck on a left hand turn with a 60 mph left to right cross wind making it very dangerous for us while we waited 80 minutes for a tow truck. The only indication of a problem was the engine light on after we were stopped nothing before hand. no sound, no warning, no vibration, just an immediate shutdown. The dealership it was towed too said it is a complete engine failure and the bearings more than likely failed and I will have to wait for a new engine. Most likely the same faulty 6.2 engine. Please do something before someone dies.

ENGINE
The engine had a bearing fail causing the engine to knock and make loud noises. The engine has been replaced and is at GMC corporate investigation center. GMC installed another engine that is also doing the same thing 150 miles after it was replaced. My families safety was put at risk because the motor could have locked up or exploded with us in the car causing a crash or possible fatality. Yes the problem was found at the dealer and caused them to investigate which is when they found the failing bearing. Yes, GMC corporation has the failed components and identified the engine needs replaced. They have yet to comment on the second engine that needs replaced. There are no warning lights to identify this issue, The lack of notification from GMC could cause drivers to be hurt by not knowing their car is failing.

ENGINE
Driving on a highway at 70 MPH then vehicle shut off / lost all power (with my kids in the car!!). Luckily we made it across three lanes of traffic to the shoulder. Got the vehicle to the dealership where they said they found large amounts of metal shavings in my engine. The engine was replaced but I am still nervous when office that it could happen again. I’m in a Facebook group where people are continually reporting the same thing happening to them. I bought this large vehicle to transport my kids and this is an extreme safety hazard (not only for us but those driving around us). This happened when I only had approximately 18,000 miles on the vehicle. Pretty much still brand new. Since then, I recently had to have the belt replaced again and the rear differentials flushed for loud grinding noises.

I had a 10 month old 2022 Yukon Denali XL. There was a constant smell of exhaust fumes inside the cabin. Took it into the dealership on multiple occasions and they found a leak in the exhaust system and supposedly fixed it. Less than 24hrs after getting it out of the shop, the engine seized up. Engine was replaced weeks later and within 7 days I started having transmission issue. GMC did absolutely nothing to keep my family of 8 safe.

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
Our family of 6 were traveling home on the Freeway, from a family road trip going about 75 mph. The engine revved up and then the entire car all electronics went black. And then flashed back on. A warning told me to "Start Engine" I attempted to, and it would not turn over. I was able to get to the shoulder to get us out of the hi-speed traffic. I put our hazards on, and the "Start Engine" warning popped up again. I attempted to start the engine again and it wouldn't turn over. All the warnings started to flash things like "check transmission, check battery.." etc. We asked our kids to stay buckled, because of the hi-speed traffic, and that it was dark outside, and we were in more of rural area. We called the nearest tow company, and had to wait about 30-40 minutes for him to get to us. The tow truck operator was not able to get the car in neutral to be able to get the Yukon on to the tow truck, he eventually got it on. The next morning the Service Tech called and said the car was completely dead when he got to it. Then, he called me later in the day and said he was able to look at the vehicle and run diagnostics and said the engine had seized. My car is less than 4 years old and had 66k miles. I had it serviced right before our family road trip at 64k miles. We have been the only owners and have always serviced it through GMC Service Centers Only. *Note*We had complained multiple times of a squeaking/chirping noise coming from the engine. Since we first received it. The service center kept the vehicle a couple of times overnight to try and diagnose. We had to pay for a new belt replacement, and the squeaking/chirping noise was never resolved. We wonder if this was a preexisting issue.

The contact owns a 2007 GMC Yukon XL. The contact stated while driving at approximately 35 MPH, all the air bags were independently deployed, except the driver's steering wheel air bag. The contact pulled over and had to cut all the side curtain air bags and the passenger’s side front air bag which were blocking the view of the road. The contact stated no warning light was illuminated. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 178,000.

ENGINE
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.

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.

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.

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

My wife was driving down the road with my Daughter and the engine simply stopped running without warning. She was able to coast to a stop on the side of the road and engage her hazard lights. When she tried to restart the engine it just cranked but never started. We had it towed to a mechanic and the mechanic told us that the engine is seized and we likely need a new engine, total cost of over $20,000. This vehicle should not be having this type of issue at 70,000 miles. If they were on a busy highway in the middle of rush hour it would have been a very dangerous situation.
